我在自定义复合控件中夸大了xml。
public class CustomView extends RelativeLayout{
private LayoutInflater inflater;
public CustomView(Context context) {
super(context);
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
addView(inflater.inflate(R.layout.common_views, null));
}
}
我已将此复合控件包含在4种不同的布局中。布局之一:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/wall1Layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/wall1withkey" >
<com.example.room.CustomView
android:id="@+id/customView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
....
</RelativeLayout>
我在viewflipper中包含的所有4种布局:
<ViewFlipper android:id="@+id/water_room_flipper"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<include layout="@layout/water_room_wall1" android:id="@+id/first" />
<include layout="@layout/water_room_wall2" android:id="@+id/second" />
<include layout="@layout/water_room_wall3" android:id="@+id/third" />
<include layout="@layout/water_room_wall4" android:id="@+id/fourth" />
</ViewFlipper>
然后我在运行时在mainactivity的方法中更改了这个复合控件的一些控件:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.water_room_view_flipper);
vf = (ViewFlipper) findViewById(R.id.water_room_flipper);
vf.setDisplayedChild(R.id.first);
}
...
public void someOnClickMethod(){
...
RelativeLayout rl = (RelativeLayout) findViewById(R.id.customView);
ImageButton newItem = (ImageButton)rl.findViewById(R.id.ImageButton01);//this is inside common_view.xml which was inflated in CustomView class(compound countrol)
newItem.setBackgroundResource(R.drawable.key_stored);
}
正如您可以看到someOnClickMethod更改其中一个控件的背景图像。但它不会在其他3种布局中生效,仅在第一种布局中生效。如何更改控件以使其在复合控件中包含的所有布局中生效?
