class DraggableButton(DragBehavior, Button):
    pass

class GridApp(App):
    def build(self):
        layout = GridLayout(cols=2)  # 创建一个2列的网格布局
        layout.add_widget(DraggableButton(text='Button 1'))  # 添加可拖动按钮
        layout.add_widget(DraggableButton(text='Button 2'))
        return layout
