RecyclerView onClick不起作用

Question

我试图通过Recyclerview项目点击启动自定义对话框，但没有任何反应。我正在使用Recyclerview的自定义onClick功能。这是我的代码：

recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(context, recyclerView ,new RecyclerItemClickListener.OnItemClickListener() { 
        @Override public void onItemClick(View view, int position) { 
         AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); 
         builder.setView(getLayoutInflater().inflate(R.layout.edit_dialog, null)); 
         builder.setTitle("Edit Item"); 
         builder.setNeutralButton("TEST", new DialogInterface.OnClickListener() { 
          @Override 
          public void onClick(DialogInterface dialogInterface, int i) { 
           Log.d("TEST","Test button was clicked in AlertDialog"); 
          } 
         }); 
         builder.setCancelable(true); 
         builder.show(); 
        } 

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

起初，我以为问题是，我并没有设立对话框按钮，但即使设立一个中立的按钮后，它仍然无法正常工作。下面是我对recyclerview的onClick功能：

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener { 
    private OnItemClickListener mListener; 

    @Override 
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {return false;} 

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

    @Override 
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {} 

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

     public void onLongItemClick(View view, int position); 
    } 

    GestureDetector mGestureDetector; 

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

     mListener = listener; 
     mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { 

      @Override 
      public boolean onSingleTapUp(MotionEvent e) {return true;} 

      @Override 
      public void onLongPress(MotionEvent e) { 
       View child = recyclerView.findChildViewUnder(e.getX(), e.getY()); 
       if (child != null && mListener != null) { 
        mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child)); 
       } 
      } 
     }); 
    } 
} 

这是我的适配器：

public class CustomCursorAdapter extends RecyclerView.Adapter<CustomCursorAdapter.TaskViewHolder>{ 

private Cursor cursor; 
private Context con; 

public CustomCursorAdapter(Context context) { 
    this.con = context; 
} 



@Override 
public TaskViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

    View view = LayoutInflater.from(con).inflate(R.layout.task_layout, parent, false); 
    return new TaskViewHolder(view); 
} 

@Override 
public void onBindViewHolder(TaskViewHolder holder, int position) { 

    int index = cursor.getColumnIndex(TaskContract.TaskEntry._ID); 
    int descriptionOfIndex = cursor.getColumnIndex(TaskContract.TaskEntry.COLUMN_DESCRIPTION); 
    int priorityofIndex = cursor.getColumnIndex(TaskContract.TaskEntry.COLUMN_PRIORITY); 

    cursor.moveToPosition(position); 

    final int id = cursor.getInt(index); 
    String description = cursor.getString(descriptionOfIndex); 
    int priority = cursor.getInt(priorityofIndex); 

    holder.itemView.setTag(id); 
    holder.taskDescriptionView.setText(description); 

    String priorityString = "" + priority; 
    holder.priorityView.setText(priorityString); 

    GradientDrawable priorityCircle = (GradientDrawable) holder.priorityView.getBackground(); 
    int priorityColor = getPriorityColor(priority); 
    priorityCircle.setColor(priorityColor); 

} 

private int getPriorityColor(int priority) { 
    int priorityColor = 0; 

    switch(priority) { 
     case 1: priorityColor = ContextCompat.getColor(con, R.color.materialRed); 
      break; 
     case 2: priorityColor = ContextCompat.getColor(con, R.color.materialOrange); 
      break; 
     case 3: priorityColor = ContextCompat.getColor(con, R.color.materialYellow); 
      break; 
     default: break; 
    } 
    return priorityColor; 
} 

@Override 
public int getItemCount() { 
    if (cursor == null) { 
     return 0; 
    } 
    return cursor.getCount(); 
} 

public Cursor swapCursor(Cursor c) { 
    if (cursor == c) { 
     return null; 
    } 
    Cursor temp = cursor; 
    this.cursor = c; 

    if (c != null) { 
     this.notifyDataSetChanged(); 
    } 
    return temp; 
} 

class TaskViewHolder extends RecyclerView.ViewHolder { 

    TextView taskDescriptionView; 
    TextView priorityView; 

    public TaskViewHolder(View itemView) { 
     super(itemView); 

     taskDescriptionView = (TextView) itemView.findViewById(R.id.taskDescription); 
     priorityView = (TextView) itemView.findViewById(R.id.priorityTextView); 
    } 
} 

}

我敢肯定，这将是您更轻松地设置里面点击监听器onBindViewHolder。 containerView - 从viewholder

@Override 
    public void onBindViewHolder(TaskViewHolder holder, int position) { 
      containerView.setOnClickListener(new DefaultInterfaceImplUtils.ClickListener() { 
       @Override 
       public void onViewClicked(View v) { 
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); 
        builder.setView(getLayoutInflater().inflate(R.layout.edit_dialog, null)); 
        builder.setTitle("Edit Item"); 
        builder.setNeutralButton("TEST", new DialogInterface.OnClickListener() { 
         @Override 
         public void onClick(DialogInterface dialogInterface, int i) { 
          Log.d("TEST", "Test button was clicked in AlertDialog"); 
         } 
        }); 
        builder.setCancelable(true); 
        builder.show(); 
       } 
      } 
     }); 
    }
