一.滑动界面:

界面:

public class SlideActivity extends Activity{
		
		private ViewPager mViewPager;	
		private ImageView mPage0;
		private ImageView mPage1;
		private ImageView mPage2;
		private ImageView mPage3;
		private ImageView mPage4;
		private ImageView mPage5;
			
	    @Override
	    public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        setContentView(R.layout.whatsnew_viewpager);
	        mViewPager = (ViewPager)findViewById(R.id.whatsnew_viewpager);        
	        mViewPager.setOnPageChangeListener(new MyOnPageChangeListener());
	       
	        
	        mPage0 = (ImageView)findViewById(R.id.page0);
	        mPage1 = (ImageView)findViewById(R.id.page1);
	        mPage2 = (ImageView)findViewById(R.id.page2);
	        mPage3 = (ImageView)findViewById(R.id.page3);
	        mPage4 = (ImageView)findViewById(R.id.page4);
	        mPage5 = (ImageView)findViewById(R.id.page5);
	        
	        //将要分页显示的View装入数组中
	        LayoutInflater mLi = LayoutInflater.from(this);
	        View view1 = mLi.inflate(R.layout.whats1, null);
	        View view2 = mLi.inflate(R.layout.whats2, null);
	        View view3 = mLi.inflate(R.layout.whats3, null);
	        View view4 = mLi.inflate(R.layout.whats4, null);
	        View view5 = mLi.inflate(R.layout.whats5, null);
	        View view6 = mLi.inflate(R.layout.whats6, null);
	        
	        //每个页面的view数据
	        final ArrayList<View> views = new ArrayList<View>();
	        views.add(view1);
	        views.add(view2);
	        views.add(view3);
	        views.add(view4);
	        views.add(view5);
	        views.add(view6);
	        
	        //填充ViewPager的数据适配器
	        PagerAdapter mPagerAdapter = new PagerAdapter() {
				
				@Override
				public boolean isViewFromObject(View arg0, Object arg1) {
					return arg0 == arg1;
				}
				
				@Override
				public int getCount() {
					return views.size();
				}

				@Override
				public void destroyItem(View container, int position, Object object) {
					((ViewPager)container).removeView(views.get(position));
				}
				
				
				
				@Override
				public Object instantiateItem(View container, int position) {
					((ViewPager)container).addView(views.get(position));
					return views.get(position);
				}
			};
			
			mViewPager.setAdapter(mPagerAdapter);
	    }    
	    

	    public class MyOnPageChangeListener implements OnPageChangeListener {
			@Override
			public void onPageSelected(int arg0) {
				switch (arg0) {
				case 0:				
					mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
					mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page));
					break;
				case 1:
					mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
					mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page));
					mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page));
					break;
				case 2:
					mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
					mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page));
					mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page));
					break;
				case 3:

					mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page));
					mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page));

					mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page));
					mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page));
					break;
				case 5:
					mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page_now));
					mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page));
					break;
				}
				//animation.setFillAfter(true);// True:图片停在动画结束位置
				//animation.setDuration(300);
				//mPageImg.startAnimation(animation);
			}
			@Override
			public void onPageScrolled(int arg0, float arg1, int arg2) {
			}
			@Override
			public void onPageScrollStateChanged(int arg0) {
			}
		}
	    public void startbutton(View v) {  
	      	Intent intent = new Intent();
			intent.setClass(SlideActivity.this,TestActivity.class);
			startActivity(intent);
			this.finish();
	      } 
}

布局:

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >  

    <android.support.v4.view.ViewPager
        android:id="@+id/whatsnew_viewpager"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" > 
        
        
        <android.support.v4.view.PagerTitleStrip
            android:id="@+id/pagertitle"
            android:layout_width="wrap_content"
            android:layout_height="0dp"
            android:layout_gravity="bottom"
            android:background="#0000"
            android:textColor="#ffff" />
    </android.support.v4.view.ViewPager>  
    
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
        > 
        
         <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
        	android:layout_marginBottom="30dp" 
        	android:gravity="center_horizontal"     >
            
            <ImageView
            	android:id="@+id/page0"
        		android:layout_width="wrap_content"
        		android:layout_height="wrap_content"        	     	
        		android:scaleType="matrix"
        		android:src="@drawable/page_now" />
            <ImageView
            	android:id="@+id/page1"
        		android:layout_width="wrap_content"
        		android:layout_height="wrap_content"
        		android:layout_marginLeft="10dp"        	     	
        		android:scaleType="matrix"
        		android:src="@drawable/page" />
            <ImageView
            	android:id="@+id/page2"
        		android:layout_width="wrap_content"
        		android:layout_height="wrap_content"
        		android:layout_marginLeft="10dp"           	     	
        		android:scaleType="matrix"
        		android:src="@drawable/page" />
            <ImageView
            	android:id="@+id/page3"
        		android:layout_width="wrap_content"
        		android:layout_height="wrap_content" 
        		android:layout_marginLeft="10dp"          	     	
        		android:scaleType="matrix"
        		android:src="@drawable/page" />
            <ImageView
            	android:id="@+id/page4"
        		android:layout_width="wrap_content"
        		android:layout_height="wrap_content" 
        		android:layout_marginLeft="10dp"          	     	
        		android:scaleType="matrix"
        		android:src="@drawable/page" />
            <ImageView
            	android:id="@+id/page5"
        		android:layout_width="wrap_content"
        		android:layout_height="wrap_content" 
        		android:layout_marginLeft="10dp"          	     	
        		android:scaleType="matrix"
        		android:src="@drawable/page" />           
            
        </LinearLayout>
        
       
    </LinearLayout>
    
	   
</FrameLayout>

每个view的布局:

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:background="@drawable/w1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
  >
    
    <TextView 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:gravity="center" 
        android:text="\n旅游日记\n是您外出旅游的必备应用" 
        android:layout_alignParentTop="true"
        android:layout_marginTop="35dp"
        android:textSize="22sp"
        android:textColor="#fff" 
        />
</RelativeLayout>

如果想要实现第一次启动显示,用SharedPreferences存储下信息就行,每次启动判断下,就ok了。
