Kivy佈局不按預期呈現

我試圖用Kivy框架提供的KV lang創建接口。我想堆疊兩個BoxLayout小部件在彼此之上。當渲染第一個佈局時，它的默認高度爲350.否則我需要減少它。Kivy佈局不按預期呈現

下面是我的佈局

# this is the rule for your root widget, defining it's look and feel.

你可以這樣做。嘗試使用size_hint，因爲它使您的應用程序響應，在所有屏幕分辨率中看起來都一樣。

BoxLayout: 
    orientation: 'vertical' 
     BoxLayout: 
      id: 'letterBox' 
      size_hint: 1, .15 

     BoxLayout: 
      id: 'contentBox' 
      size_hint: 1, .85
