Question

当我尝试旋转相对布局时，我在底部得到空白区域......这是我的xml布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"   
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    <RelativeLayout      
          android:id="@+id/columnLayout" 
          android:layout_width="match_parent" 
          android:layout_height="20dp"
          android:layout_marginLeft="40dp"> 
         <ListView 
             android:id="@+id/columnlistview"
             android:layout_width="wrap_content" 
             android:layout_height="wrap_content" 
             android:background="#b0b0b0" />  
    </RelativeLayout>
</RelativeLayout>

这就是我试图旋转相对布局的方式

RelativeLayout columnLayout = (RelativeLayout) findViewById(R.id.columnLayout);
 int w = columnLayout.getWidth();
 int h = columnLayout.getHeight();
 columnLayout.setRotation(270.0f);
 columnLayout.setTranslationX((w - h)/2);
 columnLayout.setTranslationY((h - w)/2 );
 ViewGroup.LayoutParams lp=(ViewGroup.LayoutParams)columnLayout.getLayoutParams();
 lp.height = w; 
 lp.width = h;
 columnLayout.requestLayout();

任何人都可以帮我解决如何摆脱空白..

TIA，
