RecyclerView的OnItemClick觸發之前，它的孩子的OnClick

我在我的學校項目有一些問題。當我點擊其中的ImageButton時，我的RecyclerView的OnItemClick正在觸發。RecyclerView的OnItemClick觸發之前，它的孩子的OnClick

CODE

mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, mRecyclerView, new RecyclerItemClickListener.OnItemClickListener() { 
    @Override 
    public void onItemClick(View view, int position) { 
    viewComments(posts.get(position)); 
    } 

    @Override 
    public void onItemLongClick(View view, int position) { 

    } 
}));

而這裏的RecyclerItemClickListener代碼：

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener { 

    private OnItemClickListener mListener; 
    private GestureDetector mGestureDetector; 

    public interface OnItemClickListener { 
    void onItemClick(View view, int position); 

    void onItemLongClick(View view, int position); 
    } 

    public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) { 
    mListener = listener; 

    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { 
     @Override 
     public boolean onSingleTapUp(MotionEvent e) { 
     View childView = recyclerView.findChildViewUnder(e.getX(), e.getY()); 

     if (childView.findViewById(R.id.btnRateUp).isPressed() || childView.findViewById(R.id.btnRateDown).isPressed()) { 
      return false; 
     } 

     return true; 
     } 

     @Override 
     public void onLongPress(MotionEvent e) { 
     View childView = recyclerView.findChildViewUnder(e.getX(), e.getY()); 

     if (childView != null && mListener != null) { 
      mListener.onItemLongClick(childView, recyclerView.getChildAdapterPosition(childView)); 
     } 
     } 
    }); 
    } 

    @Override 
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) { 
    View childView = view.findChildViewUnder(e.getX(), e.getY()); 

    if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) { 
     mListener.onItemClick(childView, view.getChildAdapterPosition(childView)); 
    } 

    return false; 
    } 

    @Override 
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { 
    } 

    @Override 
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) { 
    } 
}

這是我想出了檢測，如果孩子獲得點擊，

if(childView.findViewById(R.id.btnRateUp).isPressed() || childView.findViewById(R.id.btnRateDown).isPressed())

但我已經意識到方法isPressed()需要比RecyclerV更長的時間圖像OnItemClick進行處理。該代碼僅適用於不快速點擊它的情況。

btnRateUp和btnRateDown是ImageButtons及其OnClick事件在適配器的onBindViewHolder正在實施如下：

holder.getBtnRateUp().setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
    doStuff(true); 
    } 
}); 

holder.getBtnRateDown().setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
    doStuff(false); 
    } 
});
