觸摸監聽器優先於列表滾動監聽器

我有一個水平列表刷卡解僱工作，除了滑動解僱優先滾動，即如果我從左到右滑動，但在最輕微的角度，它會認爲我試圖刷卡解僱一個項目，而不是滾動列表。我覺得這個最簡單的辦法是各地擁有它的其他方式，但不知道如何去改變它或是否有更好的辦法觸摸監聽器優先於列表滾動監聽器

我修改盧卡斯Rocha的twowayview和羅馬Nurik /蒂姆魚卵swipedismissundolist

我不確定是否所有的代碼都是我應該看的地方，但是我可以告訴它相關的。

mainactivity

listView = (TwoWayView) findViewById(R.id.listView1); 


    //need to add in emptyview and list view to show and gone them when emtpy/full 


    imageAdapter = new ImageAdapter(this, products,emptyview,listView); 


    listView.setAdapter(imageAdapter); 


    VSwipeDismissList.OnDismissCallback callback = new VSwipeDismissList.OnDismissCallback() { 
     @Override 
     public VSwipeDismissList.Undoable onDismiss(AbsListView listView, final int position) { 
      // Delete the item from your adapter (sample code): 

      imageAdapter.remove(position); 
      return null; 

      } 

    };

swipedismiss

我發現了一個非常有重複的問題here

我加入叔他採取行動並採取行動將代碼移至swipedismiss的onTouch方法

 @Override 
    public boolean onInterceptTouchEvent(MotionEvent ev) { 
    switch (ev.getAction()) { 
    case MotionEvent.ACTION_DOWN: 
     xDistance = yDistance = 0f; 
     lastX = ev.getX(); 
     lastY = ev.getY(); 
     break; 
    case MotionEvent.ACTION_MOVE: 
     final float curX = ev.getX(); 
     final float curY = ev.getY(); 
     xDistance += Math.abs(curX - lastX); 
     yDistance += Math.abs(curY - lastY); 
     lastX = curX; 
     lastY = curY; 
     if(xDistance > yDistance) 
      return false; 
}
