左右滑动数据显示
1. 整体布局
FragmentLayout 容器包裹Fragment
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="demo.yuchen.com.ex04_extras.MainActivity"> <!--<fragment--> <!--android:layout_width="wrap_content"--> <!--android:layout_height="wrap_content"--> <!--android:name="demo.yuchen.com.ex04_extras.MyFragment"--> <!--android:id="@+id/fragment"--> <!--android:layout_alignParentTop="true"--> <!--android:layout_centerHorizontal="true"--> <!--android:layout_marginTop="136dp" />--> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceLarge" android:text="Large Text" android:id="@+id/textView2" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="添加Fragment" android:id="@+id/btnAdd" android:onClick="btnAdd" android:layout_below="@+id/textView2" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" /> <FrameLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@+id/btnAdd" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_marginTop="80dp" android:id="@+id/container"></FrameLayout> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="替换" android:id="@+id/btnReplace" android:onClick="btnReplace" android:layout_below="@+id/btnAdd" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" /> </RelativeLayout>
2.Fragment内容替换
public class MainActivity extends FragmentActivity {
public void btnAdd(View view) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new MyFragment()).commit();
}
public void btnReplace(View view) {
getSupportFragmentManager().beginTransaction()
.replace(R.id.container, new ViewPagerFragment()).commit();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
2. ViewPagerFragment
/**
* A simple {@link Fragment} subclass.
*/
public class ViewPagerFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View layout = inflater.inflate(R.layout.fragment_blank, container, false);
ViewPager viewPager = (ViewPager) layout.findViewById(R.id.pager);
viewPager.setAdapter(new MyPagerAdapter(getChildFragmentManager()));
return layout;
}
class MyPagerAdapter extends FragmentPagerAdapter{
List<Fragment> fragmentList = new ArrayList<>();
public MyPagerAdapter(FragmentManager fm) {
super(fm);
fragmentList.add(new PagerItemFragment());
}
@Override
public Fragment getItem(int position) {
return fragmentList.get(position);
}
@Override
public int getCount() {
return fragmentList.size();
}
}
}
3. fragment_blank.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".ViewPagerFragment"> <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent"/> </FrameLayout>
4.
public class PagerItemFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.fragment_pager_item, container, false); } }
