我用下面的代码得到它：

FloatLayout: 
    BoxLayout: 
     orientation:'vertical' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 
     Button: 
      text:'Hello' 

    Widget: 
     id: ellipse 
     size_hint: (None, None) 
     size: (dp(56), dp(56)) 
     pos_hint:{'right': 1} 
     canvas.before: 
      Color: 
       rgba: 0, 1, 0, 1 
      Ellipse: 
       size: self.size 
       pos: [dp(self.pos[0]) - dp(16), dp(self.pos[1]) + dp(16)]
