每當設置一個可移動的按鈕，它就變得不可點擊在android

Question

每當設置一個可移動的按鈕，它就變得不可點擊。 我可以移動按鈕，但按鈕點擊調用的功能不起作用。 我已經在xml文件中設置了android：onClick =「playGame」，並且在類中定義了playGame函數。但它不工作。

如果我刪除了爲可移動按鈕編寫的代碼，它的工作正常。

用於移動按鈕編寫的代碼是

@Override 
    public boolean onTouch(View view, MotionEvent event) { 
     float currX,currY; 
     int action = event.getAction(); 
     switch (action) { 
      case MotionEvent.ACTION_DOWN: { 
       mPrevX = event.getX(); 
       mPrevY = event.getY(); 
       break; 
      } 
      case MotionEvent.ACTION_MOVE: 
      { 
       currX = event.getRawX(); 
       currY = event.getRawY(); 
       ViewGroup.MarginLayoutParams marginParams = new ViewGroup.MarginLayoutParams(view.getLayoutParams()); 
       marginParams.setMargins((int)(currX - mPrevX), (int)(currY - mPrevY),0, 0); 
       RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams); 
       view.setLayoutParams(layoutParams); 
       break; 
      } 
      case MotionEvent.ACTION_CANCEL: 
       break; 
      case MotionEvent.ACTION_UP: 
       break; 
     } 
     return true; 
    } 

代碼是用於移動按鈕工作正常，但按鈕變得不可點擊。

我認爲你應該在區分點擊移動你的onTouchEvent()：

@Override 
public boolean onTouch(View view, MotionEvent event) { 

    private static final int MAX_CLICK_DURATION = 200;//!! 
    private long startClickTime; //!! 

    ... 
    switch (action) { 
     case MotionEvent.ACTION_DOWN: { 
      startClickTime = Calendar.getInstance().getTimeInMillis();//!! 

      ... 
     } 
     case MotionEvent.ACTION_MOVE: 
     { 
      ... 
     } 
     case MotionEvent.ACTION_CANCEL: 
      break; 
     case MotionEvent.ACTION_UP: 
      long clickDuration = Calendar.getInstance().getTimeInMillis() - startClickTime; 
      if(clickDuration < MAX_CLICK_DURATION) { 
       //click event has occurred 
      } 
      break; 
    } 
    return true; 
}
