Kivy Image Widget没有向右移动

Question

如果你看第一个GridLayout下面有一个Image小部件。我试图让它移动到屏幕的右侧。任何帮助都是适当的。这是代码。我需要在右侧的小部件的id是id = image。我似乎无法移动它。

我提供了更多详细信息，因为stackoverflow需要它。我认为以上是非常详细的堆栈溢出，但是您的负责人在这里是更多文本。

谢谢大家。

Answer 1

在kv文件中，执行以下操作。有关详细信息，请参阅以下示例。

1. 将GridLayout:替换为BoxLayout:，因为GridLayout与cols: 1的展示与BoxLayout orientation: 'vertical'的展示类似。
2. 删除cols: 1
3. 在Image:，添加size_hint_x: 0.4
4. 将pos_hint: {'right': 0.5}替换为pos_hint: {'right': 1}

注意

GridLayout没有名为orientation的属性。

实施例
