我的抽屉布局左侧有抽屉。
抽屉上有一个按钮,我想用新视图替换抽屉的视图。 问题是,当新视图被替换时,它不会占据整个屏幕高度。
为了说明我已经为导航抽屉视图提供了背景颜色。
我希望绿色视图占据整个屏幕高度。复制粘贴下面的代码以开始: 的 MainActivity.java
public class MainActivity extends Activity {
LayoutInflater inflater;
DrawerLayout drawer;
RelativeLayout parentRL;
RelativeLayout viewToBeRemovedRL;
View viewToBeAdded;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main_activity);
inflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
parentRL = (RelativeLayout) findViewById(R.id.parentRL);
viewToBeRemovedRL = (RelativeLayout) findViewById(R.id.viewToBeReplaced);
}
public void onRemoveView(View view) {
viewToBeAdded = inflater.inflate(R.layout.add_view, null);
viewToBeRemovedRL.setVisibility(View.GONE);
parentRL.addView(viewToBeAdded);
}
public void onOpenDrawer(View view) {
drawer.openDrawer(parentRL);
}
}
main_activity.xml
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="75dp"
android:onClick="onRemoveView"
android:text="Change View" />
</RelativeLayout>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
add_view.xml
<?xml version="1.0" encoding="utf-8"?>

答案 0 :(得分:0)
通常情况下,抽屉实际上会占据整个屏幕高度,只是视图的默认背景颜色是清晰的。
将RelativeLayout @ id / parentRL的背景设置为纯色或某些可绘制的,例如
android:background="@android:color/black"
并且您的抽屉应覆盖整个屏幕高度。
