Android 动态设置控件高度

TextView textView= (TextView)findViewById(R.id.textview);   
LinearLayout.LayoutParams linearParams =(LinearLayout.LayoutParams) textView.getLayoutParams(); //取控件textView当前的布局参数  
linearParams.height = 20;// 控件的高强制设成20  
  
linearParams.width = 30;// 控件的宽强制设成30   
  
textView.setLayoutParams(linearParams); //使设置好的布局参数应用到控件</pre>
