Recyclerview與刷卡左/右

排

我有tablayout viewpager，裏面ViewPager I'hv它正在創造一個RecyclerView片段，Recyclerview與刷卡左/右

在RecyclerVIew魚子項目我已經創建的水平滾動型，用於獲取向左掃/正確的運動，

基本上我想向左滑動該行只有75％的屏幕，然後顯示滑動式視圖，

我也用的RecyclerViewItemTouchHelper但刷卡完整的行（100％刷卡行），

我知道有創建刷卡左，右的手勢在谷歌可用庫，

但所有這些工作不正常，因爲當我們在刷卡項目recyclerview，有時倒是去ViewPager因此頁面獲得刷卡我不想即，

所以，我用HorizontalScrollView，但問題是，我無法檢測HorizontalScrollView的觸摸聽者內刷卡方向，

其實我們想一定量後自動滾動，如果滾動上HorizontalScrollView，

下面是我嘗試過的代碼。

holder.scrollContainer.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 

       int scroll1st = 0; 
       int scroll2nd = 0; 

       if(event.getAction() == MotionEvent.ACTION_DOWN){ 
        scroll1st = holder.scrollContainer.getScrollX(); 
        Log.d("SCROLL", "Scroll down callded: amt is: " + holder.scrollContainer.getScrollX()); 
        mDataSet.get(position).isFirstSwipe = false; 
       } else if (event.getAction() == MotionEvent.ACTION_UP){ 
        scroll2nd = holder.scrollContainer.getScrollX(); 
        Log.d("SCROLL", "Scroll up callded: amt is: " + holder.scrollContainer.getScrollX()); 
       } 

       Log.d("SCROLL", "max scroll amount: " + holder.scrollContainer.getMaxScrollAmount()); 

       if(event.getAction() == MotionEvent.ACTION_UP){ 

        if(scroll2nd > scroll1st && (scroll2nd - scroll1st) > 50){ 
         holder.scrollContainer.postDelayed(new Runnable() { 
          public void run() { 
           holder.scrollContainer.fullScroll(HorizontalScrollView.FOCUS_RIGHT); 
          } 
         }, 100L); 
         mDataSet.get(position).isFirstSwipe = true; 
        } else if (scroll1st > scroll2nd && (scroll1st - scroll2nd) > 50){ 
         holder.scrollContainer.postDelayed(new Runnable() { 
          public void run() { 
           holder.scrollContainer.fullScroll(HorizontalScrollView.FOCUS_LEFT); 
          } 
         }, 100L); 
         mDataSet.get(position).isFirstSwipe = true; 
        } 
    } 
       v.onTouchEvent(event); 
       return true; 
      } 
     });

基本上ACTION.DOWN事件不被調用每次所以不能得出不刷卡方向
