Activity中获取view的宽高

方式一：

view.post(new Runnable()
{
   @Override
   public void run()
   {
      Log.d("ssss","Width = "+view.getWidth());
      Log.d("ssss","Height = "+view.getHeight());
   }
});

输出：

 Width = 308
  Height = 168

view 在执行完onMeasure()后会调用 post（）

方式二：

Observer方法

view.getViewTreeObserver().addOnGlobalLayoutListener( new OnGlobalLayoutListener() {

  @Override   public void onGlobalLayout() {      // 宽高已经测量完毕      

      Log.d("ssss","Width = "+view.getWidth());
      Log.d("ssss","Height = "+view.getHeight());

view.getViewTreeObserver().removeGlobalOnLayoutListener( this) ;

   }

  }

);

方式三

@Override
public void onWindowFocusChanged(boolean hasFocus)
{
   super.onWindowFocusChanged(hasFocus);

   view.getHeight();
   Log.d("ssss","hight = "+view.getHeight());

   Log.d("ssss","Width = "+view.getWidth());

}方式四：

view.setOnClickListener(new

OnClickListener()
{

   @Override public void onClick (View v){
   

Log.d("ssss","hight = "+view.getHeight());

   Log.d("ssss","Width = "+view.getWidth());

}

  }

);
