轉換視圖點擊座標從世界座標到本地？

我這樣做，當點擊視圖我試圖獲得協調的點擊視圖。現在我正在世界共同oridates值我想要得到它在本地查看座標檢查下面的代碼轉換視圖點擊座標從世界座標到本地？

public void objectClick(View objectClicked) 
    { 

     int [] locationOfViewInWindow=new int[2]; 
     int Object = objectClicked.getId(); 
     View img= (View)findViewById(Object); 
     objectClicked.getLocationInWindow(locationOfViewInWindow); 
     Log.d("Check:","locn in window" + locationOfViewInWindow[0]+ " "+ locationOfViewInWindow[1]); 
     switch (hObject) { 


    case R.id.imageView1: 
      case R.id.imageView2:...... 
        case.R.id.imageview11: 
     ImageView drawable= (ImageView)findViewById(objectClicked.getId()); 
       Drawable d = drawable.getDrawable(); 

      boolean flag = d.getTransparentRegion().contains(locationOfViewInWindow[0], locationOfViewInWindow[1]); 

       Log.d("Check", "Opacity" + flag); 


boolean flag is returning me null because the region of transparent it is checking w.r.t to world co-ordinate 

Suggestion is appreciated

您應該擴展視圖類爲你的對象和使用的onTouchEvent獲得點擊位置：

public boolean onTouchEvent(MotionEvent event) { 
int eventaction = event.getAction(); 

switch (eventaction) { 
    case MotionEvent.ACTION_DOWN: 
     // finger touches the screen 
     break; 

    case MotionEvent.ACTION_MOVE: 
     // finger moves on the screen 
     break; 

    case MotionEvent.ACTION_UP: 
     // finger leaves the screen 
     break; 
} 

// tell the system that we handled the event and no further processing is required 
return true;

}

您可以使用event.getX（）和event.getY（）來獲取觸摸事件的位置。
