屏幕底部的内容...在使用 Kivy 添加工具栏之后
Content at bottom of screen... after adding ToolBar with Kivy
我只是想添加一个简单的 'ToolBar' 但在工具栏保持与底部对齐后我发现 AnchorLayout: 让我将工具栏锚定到顶部。但是我所有的内容现在只显示在屏幕的下半部分......我不知道为什么......调整 'center_y': 什么都不做......有没有人看到我的问题，我真的很感激。

问题是您没有考虑 size_hint (1,1) 和 pos (0,0) 的默认值。所以你的 AnchorLayout 填充你的 Main Screen，因为默认值，但是 anchor_y 设置将 MDToolBar 放在 [=15= 的顶部].
同样，您的 MDBoxLayout 也填充了整个 Main Screen，但是由于 MDRectangleFlatButton 和 MDTextField 具有预定义的大小，因此它们不要填写 MDBoxLayout。所以他们只填满 MDBoxLayout.
的下半部分
所以这是您的 kv 的一个版本（对于 Main Screen），它使用 pos_hint 作为 MDToolBar 和 minimum_height 对于 MDBoxLayout 并实际设置它的 y 值以撞到工具栏：
