我想讓這樣的事情:如何用Viewpager和Fragment分割窗口?
正如你所看到的,ViewPager是在頂部和窗口是在Viewpager和片段吐盡。
我曾嘗試以下操作:
activity_homescreen.xml:
<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=".HomeScreenActivity" tools:ignore="MergeRootFrame"
>
<android.support.v4.view.ViewPager
android:id="@+id/home_screen_view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<fragment
android:id="@+id/homescreen_fragment"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
class="com.krupalandharsh.touristguideexperiments.HomeScreenFragment" />
</RelativeLayout>
fragment_homescreen.xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="login"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="signup"/>
</LinearLayout>
HomeScreenActivity.java:
public class HomeScreenActivity extends Activity{
ViewPager homescreen_viewpager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_screen);
homescreen_viewpager = (ViewPager) findViewById(R.id.home_screen_view_pager);
HomeScreenImageAdapter adapter = new HomeScreenImageAdapter(this);
homescreen_viewpager.setAdapter(adapter);
}
} HomeScreenFragment.java:
public class HomeScreenFragment extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_homescreen, container, false);
return rootView;
}
}
HomeScreenImageAdapter.java
public class HomeScreenImageAdapter extends PagerAdapter {
private Context context;
private int[] HomeScreenImages = new int[] {
android.R.drawable.ic_menu_report_image,
android.R.drawable.ic_btn_speak_now,
android.R.drawable.ic_dialog_dialer,
};
public HomeScreenImageAdapter(Context context)
{
this.context = context;
}
@Override
public int getCount() {
return HomeScreenImages.length;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return (view == ((ImageView)object));
}
@Override
public Object instantiateItem (ViewGroup container, int position){
ImageView imageview = new ImageView(context);
imageview.setImageResource(HomeScreenImages[position]);
imageview.setScaleType(ImageView.ScaleType.FIT_CENTER);
((ViewPager)container).addView(imageview);
return imageview;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
但是,我無法見下文片段米。只顯示ViewPager。有沒有什麼想法可以讓我們像上面一樣在Viewpager和Fragment中分割屏幕?
