拖放FloatingActionButton Android

Question

我嘗試在FAB中拖放，但我的拖放操作從未調用;

這裏是我拖累激活碼：

View.OnLongClickListener onDrag = new View.OnLongClickListener() { 
     @Override 
     public boolean onLongClick(View v) { 
      View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v); 
      v.getClass(); 
      v.startDrag(ClipData.newPlainText("test", "test"), shadowBuilder, v, 0); 
      return true; 
     } 
    }; 

這裏讀心人：

protected class myDragEventListener implements View.OnDragListener { 

    // This is the method that the system calls when it dispatches a drag event to the 
    // listener. 
    public boolean onDrag(View v, DragEvent event) { 

     // Defines a variable to store the action type for the incoming event 
     final int action = event.getAction(); 
     switch (action) { 
      case DragEvent.ACTION_DRAG_ENTERED: 
       v.setBackgroundColor(Color.GRAY); 
       return true; 

      case DragEvent.ACTION_DRAG_EXITED: 
       //v.setBackgroundColor(Color.TRANSPARENT); 
       return true; 

      case DragEvent.ACTION_DRAG_STARTED: 
       return true; 

      case DragEvent.ACTION_DRAG_LOCATION: 
       //v.setVisibility(View.VISIBLE); 
       return false; 
      // return processDragStarted(event); 
      case DragEvent.ACTION_DROP: 
       Toast.makeText(context, "teste ok", Toast.LENGTH_SHORT).show();; 
      default: 
       return true; 

     } 
    } 

，我在我的工廠設置：（setOnClickListener和setOnDragListener）

您已設置錯誤地輸入您的OnLongClickListener。您應該使用setOnLongClickListener()，而不是setOnClickListener()。
