recyclerView裏面的按鈕點擊不正常

Question

我在recyclerView裏設置了一個按鈕，在那裏我點擊它Toast將顯示「RecyclerViewOnClick」而不是「RecyclerView裏面的按鈕」。

如果我想顯示「按鈕裏面的RecyclerView」，我必須點擊按鈕longClick。

如何點擊recyclerView onClick中的按鈕，它會顯示「RecyclerView內的按鈕」而不是「RecyclerViewOnClick」？

任何幫助將不勝感激。

我用recyclerView點擊模式是這樣的：

public class RecyclerViewClickListener implements RecyclerView.OnItemTouchListener { 

    private GestureDetector mGestureDetector; 
    private OnItemClickListener mListener; 


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

     void onItemLongClick(View view, int position); 
    } 

    public RecyclerViewClickListener(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 != null && mListener != null){ 
          mListener.onItemClick(childView,recyclerView.getChildLayoutPosition(childView)); 
          return true; 
         } 
         return false; 
        } 

        @Override 
        public void onLongPress(MotionEvent e) { 
         View childView = recyclerView.findChildViewUnder(e.getX(),e.getY()); 
         if(childView != null && mListener != null){ 
          mListener.onItemLongClick(childView,recyclerView.getChildLayoutPosition(childView)); 
         } 
        } 
       }); 
    } 
    @Override 
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) { 

     if(mGestureDetector.onTouchEvent(e)){ 
      return true; 

     }else 
      return false; 
    } 

    @Override 
    public void onTouchEvent(RecyclerView rv, MotionEvent e) { 
    } 

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

我recyclerView的onClick函數內部按鈕下MyAdapter擴展RecyclerView.Adapter：

public class MyViewHolder extends RecyclerView.ViewHolder{ 
     private Button creditCardPayment; 
     public MyViewHolder(View itemView) { 
      super(itemView); 
      creditCardPayment=(Button)itemView.findViewById(R.id.creditCardPayment); 
      //I want to show this toast when i onClick button. 
      creditCardPayment.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
        Toast.makeText(view.getContext(),"Button inside RecyclerView",Toast.LENGTH_SHORT).show(); 
       } 
      }); 
     } 

這是我的片段聲明recyclerView點擊模式：

@Override 
       public void onActivityCreated(@Nullable Bundle savedInstanceState) { 
        super.onActivityCreated(savedInstanceState); 

        recyclerView.addOnItemTouchListener(new RecyclerViewClickListener(getActivity(),recyclerView, new RecyclerViewClickListener.OnItemClickListener() { 
         @Override 
         public void onItemClick(View view, int position) { 
    //When i click the button , the toast show "RecyclerViewOnClick" not "Button //inside recyclerView"      

Toast.makeText(getActivity(),"RecyclerViewOnClick",Toast.LENGTH_SHORT).show(); 
         } 

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

         } 
        })); 
       } 

這是我的recyclerView佈局，我設置了一個按鈕：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="?android:attr/selectableItemBackground" 
    android:clickable="true" 
    android:orientation="horizontal"> 

    <LinearLayout 
     android:layout_weight="1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:padding="10dp"> 

     <TextView 
      android:id="@+id/paymentStatus" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_gravity="center" 
      android:layout_marginTop="8dp" 
      android:text="@string/paymentStatus" 
      android:textColor="@android:color/black" 
      android:textSize="18dp" /> 
     //onClick over here 
     <Button 
      android:id="@+id/creditCardPayment" 
      android:layout_width="80dp" 
      android:layout_height="30dp" 
      android:layout_alignParentRight="true" 
      android:layout_gravity="center" 
      android:background="@drawable/corner_light_dark_blue" 
      android:text="@string/creditCardPayment" 
      android:textColor="@android:color/white" /> 

    </LinearLayout> 

</RelativeLayout>

正如您所設置TouchListener到recylerview你永遠不會在同一時間onClick事件的按鈕。 Button的OnClick監聽器很好，但RecyclerView的OnTouchListener優先於Button的監聽器OnClick。

因此，實現兩者的最佳方式是設置整個項目的點擊偵聽器，就像按鈕的點擊偵聽器一樣。

刪除此

recyclerView.addOnItemTouchListener(new RecyclerViewClickListener(getActivity(),recyclerView, new RecyclerViewClickListener.OnItemClickListener() { 
    @Override 
    public void onItemClick(View view, int position) { 
     //When i click the button , the toast show "RecyclerViewOnClick" not "Button //inside recyclerView"      

     Toast.makeText(getActivity(),"RecyclerViewOnClick",Toast.LENGTH_SHORT).show(); 
    } 

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

    } 
})); 

而是添加此呼籲在ViewHolder就像下面。

public class MyViewHolder extends RecyclerView.ViewHolder{ 
    private Button creditCardPayment; 
    public MyViewHolder(View itemView) { 
     super(itemView); 
     creditCardPayment=(Button)itemView.findViewById(R.id.creditCardPayment); 
     //I want to show this toast when i onClick button. 
     creditCardPayment.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Toast.makeText(view.getContext(),"Button inside RecyclerView",Toast.LENGTH_SHORT).show(); 
      } 
     }); 

     //recyclerView's item click 
     itemView.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Toast.makeText(getActivity(),"RecyclerViewOnClick",Toast.LENGTH_SHORT).show();      
      } 
     }); 
    }
