在一个while循环内的Android Touch有条件吗？

Question

好吧，假设我一次有40个imageViews在屏幕上，我想检查是否有任何触摸，是否有任何方法来浓缩我的代码，并写一个循环为我做？现在我的代码看起来像只有更长的下面，因为我有一个巨大的条件每个图像。它使得无尽的和总体看起来的代码。每个条件唯一不同的是索引值。

public boolean onTouch(View v, MotionEvent event) 
{ 
    switch (event.getAction()) 
    { 

     case MotionEvent.ACTION_MOVE: 

      float x = event.getRawX(); 
      float y = event.getRawY(); 


       if (x > imageViewArray[0].getX() && x < imageViewArray[0].getX() + imageViewArray[0].getWidth() && y > imageViewArray[0].getY() && y < imageViewArray[0].getY() + imageViewArray[0].getHeight()) { 

        System.out.println("imageView0 was touched"); 
       } 
       if (x > imageViewArray[1].getX() && x < imageViewArray[1].getX() + imageViewArray[1].getWidth() && y > imageViewArray[1].getY() && y < imageViewArray[1].getY() + imageViewArray[1].getHeight()) { 

        System.out.println("imageView1 was touched"); 

       } 
       if (x > imageViewArray[2].getX() && x < imageViewArray[2].getX() + imageViewArray[2].getWidth() && y > imageViewArray[2].getY() && y < imageViewArray[2].getY() + imageViewArray[2].getHeight()) { 

        System.out.println("imageView2 was touched"); 

       } 

      break; 
    } 
    return true; 
}

试试这个。

ArrayList<ImageView> myImageViewsList = new ArrayList<ImageView>(); 
    ... 
    //Add ImageView's to list 
    ... 
    public boolean onTouch(View v, MotionEvent event) 
    { 
     ImageView touchedView; 

     for(ImageView view : myImageViewsList) { 
      Rect rect; 
      view.getDrawingRect(rect); 
      if(rect.contains((int)event.getX(),(int)event.getY())) { 
       touchedView = view; // that is a touched ImageView 
       break; 
      } 
     } 
     return true; 
    }
