Android多圖像移動調整大小問題

我想在我的android應用程序中移動旋轉和調整圖像大小，我發現這個代碼從stackoverflow和它的工作完全符合我的要求....但現在我需要移動兩個圖像當我切換到第二個圖像時，此代碼將重複第一個圖像移動。 1）我怎麼做那個... 2）我試圖爲這兩個圖像添加單獨的觸摸監聽器，但沒有一個圖像沒有「T動彈Android多圖像移動調整大小問題

需要使用與onTouch事件自定義類的ImageView的

之一

iv_choose_hats = (ImageView)findViewById(R.id.iv_chooseHats); 
iv_choose_hats.setScaleType(ScaleType.MATRIX); 
iv_choose_hats.setOnTouchListener(new Image_OnTouch()); 

public class Image_OnTouch implements OnTouchListener { 
    @Override 
    public boolean onTouch(View v, MotionEvent event) { 

    } 
}
