这篇文章主要是自己研究如何对底部菜单进行布局,并简单的实现点击不同"按钮"实现图片切换和背景切换的功能,最后通过PopupWindows实现弹出菜单,点击不同按钮能实现不同方法,相当于美图秀秀编辑图片的功能吧!它并没有涉及到Fragment碎片切换页面的功能,因为页面始终显示被处理的图片.这是我初学Android的一篇基础性文章和在线思想笔记,网上有很多更优秀的demo,不过也希望对大家有用~

首先介绍两种方法实现底部菜单点击不同图标显示选中状态的效果.

    (可参考简短文章： Android_UI_点击按钮切换背景效果实现

)

    一. 底部菜单 第一种方法

    它显示的效果如下图所示,其中底部菜单布局采用多个LinearLayout进行,点击不同"按钮"可以改变其背景图片.

首先介绍它的activity_main.xml布局：

1.它采用3个RelativeLayout相对布局进行,分别对应标题路径、中间显示图片和底部的菜单栏;

2.底部菜单栏由5个LinearLayout水平布局组成,每一个LinearLayout都由ImageView和TextView组成.

    代码如下：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/container"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="com.example.touchimagetest.MainActivity"
  tools:ignore="MergeRootFrame" >
   <!-- 顶部路径 -->
  <RelativeLayout 
    android:id="@+id/MyLayout_top"
    android:orientation="horizontal" 
    android:layout_width="fill_parent"
    android:layout_height="40dp" 
    android:layout_alignParentTop="true"
    android:gravity="center">
    <TextView
      android:id="@+id/textView1"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textSize="15sp"
      android:text="显示图片操作" />
  </RelativeLayout>
  <!-- 底部按钮 -->
  <RelativeLayout
    android:id="@+id/MyLayout_bottom"
    android:orientation="horizontal" 
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_alignParentBottom="true"
    android:background="@drawable/image_toolbar_bg"
    android:gravity="center">
    <LinearLayout 
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="horizontal"
      android:layout_alignParentBottom="true" >
       
      <LinearLayout 
        android:id="@+id/layout_watch"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_weight="1"
        android:gravity="center"  
        android:orientation="vertical" >  
        <ImageView  
          android:id="@+id/image_watch"  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
           	android:padding="3dp" 
          android:src="@drawable/tab_watch_btn" />  
        <TextView  
          android:id="@+id/textview_watch"
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"   
          android:text="查看"  
          android:textColor="#ffffff"  
          android:textSize="10sp" />  
      </LinearLayout>  
      
      <LinearLayout 
        android:id="@+id/layout_increase"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_weight="1"
        android:gravity="center"  
        android:orientation="vertical" >  
        <ImageView  
          android:id="@+id/image_increase"  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
           	android:padding="3dp" 
          android:src="@drawable/tab_increase_btn" />  
        <TextView  
          android:id="@+id/textview_increase"
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"   
          android:text="增强"  
          android:textColor="#ffffff"  
          android:textSize="10sp" />  
      </LinearLayout>  
      
      <LinearLayout 
        android:id="@+id/layout_effect"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_weight="1"
        android:gravity="center"  
        android:orientation="vertical" >  
        <ImageView  
          android:id="@+id/image_effect"  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
           	android:padding="3dp" 
          android:src="@drawable/tab_effect_btn" />  
        <TextView  
          android:id="@+id/textview_effect"
    android:layout_width="wrap_content"  
android:layout_height="wrap_content"   
android:text="特效"  
android:textColor="#ffffff"  
android:textSize="10sp" />  
</LinearLayout>
<LinearLayout 
android:id="@+id/layout_frame"  
android:layout_width="wrap_content"  
android:layout_height="wrap_content"  
android:layout_weight="1"
android:gravity="center"  
android:orientation="vertical" >  
<ImageView  
android:id="@+id/image_frame"  
android:layout_width="wrap_content"  
android:layout_height="wrap_content"  
android:padding="3dp" 
android:src="@drawable/tab_frame_btn" />  
<TextView  
android:id="@+id/textview_frame"
android:layout_width="wrap_content"  
android:layout_height="wrap_content"   
android:text="相框"  
android:textColor="#ffffff"  
android:textSize="10sp" />  
</LinearLayout> 
<LinearLayout 
android:id="@+id/layout_person"  
android:layout_width="wrap_content"  
android:layout_height="wrap_content"  
android:layout_weight="1"
android:gravity="center"  
android:orientation="vertical" >  
<ImageView  
android:id="@+id/image_person"  
android:layout_width="wrap_content"  
android:layout_height="wrap_content"  
android:padding="3dp" 
android:src="@drawable/tab_person_btn" />  
<TextView  
android:id="@+id/textview_person"
android:layout_width="wrap_content"  
android:layout_height="wrap_content"   
android:text="美白"  
android:textColor="#ffffff"  
android:textSize="10sp" />  
</LinearLayout>
</LinearLayout>  		
</RelativeLayout>
<!-- 显示图片 -->
<RelativeLayout
  android:id="@+id/Content_Layout" 
android:orientation="horizontal"
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:layout_above="@id/MyLayout_bottom" 
android:layout_below="@id/MyLayout_top"
android:background="#EFDFDF"
android:gravity="center">
<ImageView
  android:id="@+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:scaleType="matrix" />
</RelativeLayout>
</RelativeLayout>

  此时你需要注意的是为每个LinearLayout中ImageView指定src时并不是原图片,而是drawable中的xml文件,如<ImageView android:id="@+id/image_watch".. />.

    同时每个drawable中的xml文件对应每个相应的按钮,上图中effect(效果)、increase(增强)、frame(相框)、watch(查看)、person(美白).其中每个格式基本如下,如tab_watch_btn.xml：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/image_icon_watch_sel" android:state_selected="true"/>
    <item android:drawable="@drawable/image_icon_watch_sel" android:state_pressed="true"/> 
    <item android:drawable="@drawable/image_icon_watch_nor"/> 
</selector>

其中state_selected表示"选中"状态,state_pressed表示"点击"效果,而最后的<item android:drawable="@drawable/image_icon_watch_nor"/> 表示默认情况显示图片,原图片如下：

    同时设置选中状态"按钮"的背景加黑效果,在drawable中添加selector_tab_background.xml文件:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
  <item android:drawable="@drawable/image_home_layout_bg" android:state_pressed="true"/>  
    <item android:drawable="@drawable/image_home_layout_bg" android:state_selected="true"/>  
</selector>

//自定义变量
private LinearLayout layoutWatch;             //查看图片
private LinearLayout layoutIncrease;           //增强图片
private LinearLayout layoutEffect;               //图片特效
private LinearLayout layoutFrame;              //图片边框
private LinearLayout layoutPerson;             //图片美白

private ImageView imageWatch;    
private ImageView imageIncrease;  
private ImageView imageEffect;  
private ImageView imageFrame;  
private ImageView imagePerson;

//创建活动
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //布局
    layoutWatch = (LinearLayout) findViewById(R.id.layout_watch);
    layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase);
    layoutEffect = (LinearLayout) findViewById(R.id.layout_effect);
    layoutFrame = (LinearLayout) findViewById(R.id.layout_frame);
    layoutPerson = (LinearLayout) findViewById(R.id.layout_person);
    //图标 
    imageWatch = (ImageView) findViewById(R.id.image_watch);
    imageIncrease = (ImageView) findViewById(R.id.image_increase);
    imageEffect = (ImageView) findViewById(R.id.image_effect);
    imageFrame = (ImageView) findViewById(R.id.image_frame);
    imagePerson = (ImageView) findViewById(R.id.image_person);
    //初始化布局
    initView();

    //按钮一 监听事件 查看图片
    layoutWatch.setOnClickListener( new OnClickListener() {
    	@Override
    	public void onClick(View v) {
      //设置背景图片加深
    		Toast.makeText(MainActivity.this, "点击按钮1", Toast.LENGTH_SHORT).show();
    		layoutWatch.setBackgroundResource(R.drawable.selector_tab_background);
    		//设置图标选中情况
    		layoutWatch.setSelected(true);
    		layoutIncrease.setSelected(false);
    		layoutEffect.setSelected(false);
    		layoutFrame.setSelected(false);
    		layoutPerson.setSelected(false);
    	}
    });
    //按钮二 监听事件增强图片
    layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase);
    layoutIncrease.setOnClickListener( new OnClickListener() {
    	@Override
    	public void onClick(View v) {
    		layoutIncrease.setBackgroundResource(R.drawable.selector_tab_background);
    		//设置图标选中情况
    		layoutWatch.setSelected(false);
    		layoutIncrease.setSelected(true);
    		layoutEffect.setSelected(false);
    		layoutFrame.setSelected(false);
    		layoutPerson.setSelected(false);
    	}
    });
    //按钮三 监听事件图片特效
    layoutEffect = (LinearLayout) findViewById(R.id.layout_effect);
    layoutEffect.setOnClickListener( new OnClickListener() {
    	@Override
    	public void onClick(View v) {
    		//设置背景图片
    		layoutEffect.setBackgroundResource(R.drawable.selector_tab_background);
    		//设置图标选中情况
    		layoutWatch.setSelected(false);
    		layoutIncrease.setSelected(false);
    		layoutEffect.setSelected(true);
    		layoutFrame.setSelected(false);
    		layoutPerson.setSelected(false);
    	}
    });
    //按钮四 监听事件图片相框
    layoutFrame = (LinearLayout) findViewById(R.id.layout_frame);
    layoutFrame.setOnClickListener( new OnClickListener() {
    	@Override
    	public void onClick(View v) {
    		//设置背景图片
    		layoutFrame.setBackgroundResource(R.drawable.selector_tab_background);
    		//设置图标选中情况
    		layoutWatch.setSelected(false);
    		layoutIncrease.setSelected(false);
    		layoutEffect.setSelected(false);
    		layoutFrame.setSelected(true);
    		layoutPerson.setSelected(false);

    	}
    });
  	//按钮五 监听事件图片美白
    layoutPerson = (LinearLayout) findViewById(R.id.layout_person);
    layoutPerson.setOnClickListener( new OnClickListener() {
    	@Override
    	public void onClick(View v) {
    		//设置背景图片
    		layoutPerson.setBackgroundResource(R.drawable.selector_tab_background);
    		//设置图标选中情况
    		layoutWatch.setSelected(false);
    		layoutIncrease.setSelected(false);
    		layoutEffect.setSelected(false);
    		layoutFrame.setSelected(false);
    		layoutPerson.setSelected(true);

    	}
    });
}

//初始化布局
private void initView()
{
  imageWatch.setImageResource(R.drawable.tab_watch_btn);
  imageIncrease.setImageResource(R.drawable.tab_increase_btn);
  imageEffect.setImageResource(R.drawable.tab_effect_btn);
  imageFrame.setImageResource(R.drawable.tab_frame_btn);
  imagePerson.setImageResource(R.drawable.tab_person_btn);
}

    二. 底部菜单 第二种方法

    其中activity_main.xml中布局与第一个相同,不同的是在xml中就指定drawable-hdpi中原图片名,因为它不在调用drawable如 tab_watch_btn.xml文件,而使用代码直接操作. 其中5个LinearLayout一个如下所示：

<LinearLayout 
     android:id="@+id/layout_watch"  
     android:layout_width="wrap_content"  
     android:layout_height="wrap_content"  
     android:layout_weight="1"
     android:gravity="center"  
     android:orientation="vertical" >  
     <ImageView  
       android:id="@+id/image_watch"  
       android:layout_width="wrap_content"  
       android:layout_height="wrap_content"  
        android:padding="3dp" 
       android:src="@drawable/image_icon_watch_nor" />  
     <TextView  
       android:id="@+id/textview_watch"
       android:layout_width="wrap_content"  
       android:layout_height="wrap_content"   
       android:text="查看"  
       android:textColor="#ffffff"  
       android:textSize="10sp" />  
</LinearLayout>

    同时5个LinearLayout(查看、增强、特效、相框、美白)设置触屏响应事件：

layoutWatch.setOnTouchListener(new OnTouchListener() {
  @Override
  public boolean onTouch(View v, MotionEvent event) {			   
    if(event.getAction() == MotionEvent.ACTION_DOWN) {	   
      //按下背景图片			 	
      layoutWatch.setBackgroundResource(R.drawable.image_home_layout_bg);
      layoutIncrease.setBackgroundResource(R.drawable.image_home_layout_no);
      layoutEffect.setBackgroundResource(R.drawable.image_home_layout_no);
      layoutFrame.setBackgroundResource(R.drawable.image_home_layout_no);
      layoutPerson.setBackgroundResource(R.drawable.image_home_layout_no);
      //设置按钮图片
      imageWatch.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_watch_sel));	
      imageIncrease.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_increase_nor)); 
      imageEffect.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_effect_nor)); 
      imageFrame.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_frame_nor)); 
      imagePerson.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_person_nor)); 
    }
    return false;	   
  }	   
});

 

bottomReturnBtn.setOnTouchListener(new OnTouchListener() {  
    //这段代码仅仅实现点击一次改变图标功能
  public boolean onTouch(View v, MotionEvent event) {  
    Button upStepBtn = (Button) v;  
    if(event.getAction() == MotionEvent.ACTION_DOWN){  
      upStepBtn.setBackgroundResource(R.drawable.bottom_sub_order_btn);  
    }else if(event.getAction() == MotionEvent.ACTION_UP){  
      upStepBtn.setBackgroundResource(R.drawable.bottom_return_check);  
      finish();   
    }  
    return false;  
  }  
});

    三. PopupWindow实现弹出菜单

     

 

然后讲解如何通过PopupWindow实现下面的功能.效果如下图所示,简单实现PopupWindow功能可结合下面两篇文章：

android之popupWindow在指定位置上的显示

 

[android开发] 使用PopupWindow实现页面点击顶部弹出下拉菜单

 

    首先,为PopupWindow设置动画效果,在res文件夹下添加文件夹anim,然后添加anim_entry.xml文件：

<?xml version="1.0" encoding="utf-8"?>  
<set xmlns:android="http://schemas.android.com/apk/res/android">	
  <translate	
    android:fromXDelta="0"	
    android:toXDelta="0"	
    android:fromYDelta="120"	
    android:toYDelta="0"	
    android:duration="500" />	
</set>

    它是出现效果：从菜单栏底部向上弹出,同时添加anim_exit.xml:

<?xml version="1.0" encoding="UTF-8"?>  
<set xmlns:android="http://schemas.android.com/apk/res/android" >  
  <!-- 透明度消失 -->
  <alpha 
    android:fromAlpha="1.0" 
    android:toAlpha="0.0" 
    android:duration="200" />
</set>

    最后在res/values文件夹styles.xml中添加动画效果,通过调用name="AnimationPreview"可以实现动画：

<!-- 定义popupwindows动画效果 -->
 <style name="AnimationPreview">  
     <item name="android:windowEnterAnimation">@anim/anim_entry</item>  
     <item name="android:windowExitAnimation">@anim/anim_exit</item>  
 </style>

    然后你需要自定义弹出PopupWindow的布局xml文件,如popup_effect.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content" >  
  
  <LinearLayout  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:layout_alignParentBottom="true"  
    android:background="@drawable/image_button_bg_left"  
    android:orientation="vertical" >  
    <LinearLayout  
      android:layout_width="wrap_content"  
      android:layout_height="wrap_content"  
      android:layout_gravity="center_horizontal"  
      android:layout_marginTop="5dp"  
      android:orientation="horizontal" > 
       
      <LinearLayout  
        android:id="@+id/layout_effect_hj"
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_margin="2dp"  
        android:layout_weight="1"  
        android:orientation="vertical" >  
        <ImageView  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
          android:layout_gravity="center_horizontal"  
          android:layout_marginTop="1.0dip"  
          android:src="@drawable/image_effect_hj" />
        <TextView  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
          android:layout_gravity="center_horizontal"  
          android:layout_marginTop="1.0dip"  
          android:shadowColor="#ff000000"  
          android:shadowDx="1.0"  
          android:shadowDy="1.0"  
          android:shadowRadius="1.0"  
          android:text="怀旧"  
          android:textColor="#ffffffff"  
          android:textSize="13.0dip" />  
      </LinearLayout>  
  
      <LinearLayout  
        android:id="@+id/layout_effect_fd"
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_margin="2dp"  
        android:layout_weight="1"  
        android:orientation="vertical" >  
        <ImageView  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
          android:layout_gravity="center_horizontal"  
          android:layout_marginTop="1.0dip"  
          android:src="@drawable/image_effect_fd" />  
        <TextView  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
          android:layout_gravity="center_horizontal"  
          android:layout_marginTop="1.0dip"  
          android:shadowColor="#ff000000"  
          android:shadowDx="1.0"  
          android:shadowDy="1.0"  
          android:shadowRadius="1.0"  
          android:text="浮雕"  
          android:textColor="#ffffffff"  
          android:textSize="13.0dip" />  
      </LinearLayout>  

      <LinearLayout  
        android:id="@+id/layout_effect_gz"
        android:layout_width="wrap_content"

        android:layout_margin="2dp"  
        android:layout_weight="1"  
        android:orientation="vertical" >  
        <ImageView  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"  
          android:layout_gravity="center_horizontal"  
          android:layout_marginTop="1.0dip"  
          android:src="@drawable/image_effect_gz" /> 
        <TextView  
          android:layout_width="wrap_content"  
          android:layout_height="wrap_content"

android:shadowDy="1.0"  
android:shadowRadius="1.0"  
android:text="光照"  
android:textColor="#ffffffff"  
android:textSize="13.0dip" />  
</LinearLayout>  
  
<LinearLayout

    它的在Xml中Graphical Layout显示效果如下图所示：

    添加5个自定义变量：

//弹出按钮
private PopupWindow popupWindow1;     
private PopupWindow popupWindow2;
private PopupWindow popupWindow3;
private PopupWindow popupWindow4;
private PopupWindow popupWindow5;

    然后当点击"相框"布局LinearLayout时,添加代码如下(其他类似)：

//按钮四 监听事件图片相框
layoutFrame.setOnClickListener( new OnClickListener() {
  @Override
  public void onClick(View v) {
    //载入PopupWindow
    if (popupWindow4 != null&&popupWindow4.isShowing()) {  
      popupWindow4.dismiss();  
      return;  
    } else {  
      initmPopupWindowView(4);   //number=4
      int[] location = new int[2];  
      v.getLocationOnScreen(location); 
      Toast.makeText(MainActivity.this, ""+location[0], Toast.LENGTH_SHORT).show();
      popupWindow4.showAtLocation(v, Gravity.NO_GRAVITY, location[0], location[1]-popupWindow4.getHeight());
    }
  }
});

    其中initmPopupWindowView(int number)为自定义函数,参数对应的是点击LinearLayout的序号,点击"按钮"4即传入数字4：

public void initmPopupWindowView(int number) {  
    View customView = null;
    // 获取自定义布局文件  
    if(number==1) { //查看
      customView = getLayoutInflater().inflate(R.layout.popup_watch, null, false);  
      // 创建PopupWindow实例  (250,180)分别是宽度和高度  
      popupWindow1 = new PopupWindow(customView, 250, 280); 
      // 设置动画效果 [R.style.AnimationFade 是自己事先定义好的]  
      popupWindow1.setAnimationStyle(R.style.AnimationPreview);  
      // 自定义view添加触摸事件  
      customView.setOnTouchListener(new OnTouchListener() {  
        @Override  
        public boolean onTouch(View v, MotionEvent event) {  
          if (popupWindow1 != null && popupWindow1.isShowing()) {  
            popupWindow1.dismiss();  
            popupWindow1 = null;  
          }  
          return false;  
        }  
      });  
    }
     if(number==2) { //增强
     	customView = getLayoutInflater().inflate(R.layout.popup_increase, null, false);  
     	popupWindow2 = new PopupWindow(customView, 450, 150);
     	// 使其聚集 要想监听菜单里控件的事件就必须要调用此方法   
       popupWindow2.setFocusable(true);  
       // 设置允许在外点击消失   
       popupWindow2.setOutsideTouchable(true); 
       popupWindow2.setAnimationStyle(R.style.AnimationPreview);  
       // 自定义view添加触摸事件  
       customView.setOnTouchListener(new OnTouchListener() {  
         @Override  
         public boolean onTouch(View v, MotionEvent event) {  
           if (popupWindow2 != null && popupWindow2.isShowing()) {  
             popupWindow2.dismiss();  
             popupWindow2 = null;  
           }  
           return false;  
         }  
       });  
     }
    if(number==3) { //效果
      customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false);  
      popupWindow3 = new PopupWindow(customView, 450, 150);
      // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法   
      popupWindow3.setFocusable(true);  
      // 设置允许在外点击消失   
      popupWindow3.setOutsideTouchable(true); 
      popupWindow3.setAnimationStyle(R.style.AnimationPreview);  
      // 自定义view添加触摸事件  
      customView.setOnTouchListener(new OnTouchListener() {  
        @Override  
        public boolean onTouch(View v, MotionEvent event) {  
          if (popupWindow3 != null && popupWindow3.isShowing()) {  
            popupWindow3.dismiss();  
            popupWindow3 = null;  
          }  
          return false;  
        }  
      });  
    }
    if(number==4) {
      customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false);  
      popupWindow4 = new PopupWindow(customView, 450, 150);
      // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法   
      popupWindow4.setFocusable(true);  
      popupWindow4.setAnimationStyle(R.style.AnimationPreview);  
      // 自定义view添加触摸事件  
      customView.setOnTouchListener(new OnTouchListener() {  
        @Override  
        public boolean onTouch(View v, MotionEvent event) {  
          if (popupWindow4 != null && popupWindow4.isShowing()) {  
            popupWindow4.dismiss();  
            popupWindow4 = null;  
          }  
          return false;  
        }  
      });  
    }
    if(number==5) {
      customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false);  
      popupWindow5 = new PopupWindow(customView, 450, 150);
      // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法   
      popupWindow5.setFocusable(true);  
      popupWindow5.setAnimationStyle(R.style.AnimationPreview);  
      // 自定义view添加触摸事件  
      customView.setOnTouchListener(new OnTouchListener() {  
        @Override  
        public boolean onTouch(View v, MotionEvent event) {  
          if (popupWindow5 != null && popupWindow5.isShowing()) {  
            popupWindow5.dismiss();  
            popupWindow5 = null;  
          }  
          return false;  
        }  
      });  
    } //end if
  }

    四. PopupWindow实现点击效果

   

做到这里,你就能实现点击底部菜单实现弹出PopupWindows效果,但显然是不足的.怎样通过点击弹出PopupWindow中的按钮实现做不同的事情呢?下面讲解,你只需要添加下面的代码即可实现"特效"效果.

   

代码如下,你可以自定义函数实现不同效果功能(结合前面几篇文章,我的美图秀秀基本完成)：

if(number==3) { //效果
  customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false);  
  popupWindow3 = new PopupWindow(customView, 450, 150);
  // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法   
  popupWindow3.setFocusable(true);  
  // 设置允许在外点击消失   
  popupWindow3.setOutsideTouchable(true); 
  popupWindow3.setAnimationStyle(R.style.AnimationPreview);  
  // 自定义view添加触摸事件  
  customView.setOnTouchListener(new OnTouchListener() {  
    @Override  
    public boolean onTouch(View v, MotionEvent event) {  
      if (popupWindow3 != null && popupWindow3.isShowing()) {  
        popupWindow3.dismiss();  
        popupWindow3 = null;  
      }  
      return false;  
    }  
  });  
  //判断点击子菜单不同按钮实现不同功能
  LinearLayout layoutEffect1 = (LinearLayout) customView.findViewById(R.id.layout_effect_hj);
  layoutEffect1.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
      Toast.makeText(MainActivity.this, "效果-怀旧", Toast.LENGTH_SHORT).show();
    }
  });
  LinearLayout layoutEffect2 = (LinearLayout) customView.findViewById(R.id.layout_effect_fd);
  layoutEffect2.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
      Toast.makeText(MainActivity.this, "效果-浮雕", Toast.LENGTH_SHORT).show();
    }
  });
  LinearLayout layoutEffect3 = (LinearLayout) customView.findViewById(R.id.layout_effect_gz);
  layoutEffect3.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
      Toast.makeText(MainActivity.this, "效果-光照", Toast.LENGTH_SHORT).show();
    }
  });
  LinearLayout layoutEffect4 = (LinearLayout) customView.findViewById(R.id.layout_effect_sm);
  layoutEffect4.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
      Toast.makeText(MainActivity.this, "效果-素描", Toast.LENGTH_SHORT).show();
      //打开图片
      OpenImage();
    }
  });
  LinearLayout layoutEffect5 = (LinearLayout) customView.findViewById(R.id.layout_effect);
  layoutEffect5.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
      Toast.makeText(MainActivity.this, "效果-锐化", Toast.LENGTH_SHORT).show();
    }
  });
}

    五. 总结

 

 

本文章主要讲述如何加载菜单栏在底部,同时讲述PopupWindows弹出事件,其实更好的布局方法是通过适配器,但是我才学Android,很多东西还不懂.所以它只是一篇初级文章,但完全能实现需要功能.

Android之用PopupWindow实现弹出菜单

 

   

 

 

最后希望文章对大家有所帮助,如果文章中有错误或不足之处见谅~
