設置RelativeLayout時，ImageViews會縮小尺寸參數高度

Question

我有一個活動就像底部工作表一樣。我已經設置好了，所以用戶可以用手指拖動它，它會相應地移動。所有的效果都很好，除非當底部圖被拖動時，無論哪個圖標離底部最近都會被調整大小，而不是從屏幕上掉下來。這會產生一種奇怪的和不希望的效果。

這裏是正在發生的一個畫面：

下面是調整的方法：

public void setAdjustableTouchListener() { 
     full.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       switch (event.getActionMasked()) { 
        case MotionEvent.ACTION_DOWN: 
         mDragStartY = event.getY(); 
         mDraggingStarted = SystemClock.elapsedRealtime(); 
         mPointerOffset = event.getRawY() + main.getMeasuredHeight(); 
         return true; 
        case MotionEvent.ACTION_UP: 
         if (mDragStartY < (event.getY() + TAP_DRIFT_TOLERANCE) && mDragStartY > (event.getY() - TAP_DRIFT_TOLERANCE) 
           && ((SystemClock.elapsedRealtime() - mDraggingStarted) < SINGLE_TAP_MAX_TIME)) { 
          result = "Dismissed"; 
          finish(); 
         } else { 
          if (main.getMeasuredHeight() > (viewConversion + heightDifference)) { 
           ResizeAnimation a = new ResizeAnimation(main); 
           a.setDuration(500); 
           a.setParams(main.getMeasuredHeight(), extendedViewHeight); 
           main.startAnimation(a); 
          } else if (main.getMeasuredHeight() < (viewConversion + heightDifference) 
            && main.getMeasuredHeight() > viewConversion) { 
           ResizeAnimation a = new ResizeAnimation(main); 
           a.setDuration(500); 
           a.setParams(main.getMeasuredHeight(), viewConversion); 
           main.startAnimation(a); 
          } else if (main.getMeasuredHeight() < viewConversion && main.getMeasuredHeight() > (viewConversion/2)) { 
           ResizeAnimation a = new ResizeAnimation(main); 
           a.setDuration(500); 
           a.setParams(main.getMeasuredHeight(), viewConversion); 
           main.startAnimation(a); 
          } else { 
           result = "Dismissed"; 
           finish(); 
          } 
         } 
         return true; 
        case MotionEvent.ACTION_MOVE: 
         if (mPointerOffset - event.getRawY() < extendedViewHeight) 
          setPrimaryContentHeight((int) (mPointerOffset - event.getRawY())); 
         return true; 
        default: 
         return true; 
       } 
      } 
     }); 
    }

試試這個

imageView.setScaleType(ImageView.ScaleType.FIT_XY);
