Question

它在预览中显示良好，但是当我运行时，界面隐藏了最后一个按钮。我该如何解决这个问题？

编辑：现在我想起来，我认为这是TitleBar的大小。我该如何解决这个问题？

Answer 1

预览中没有操作栏，但在模拟器中你获得了操作栏，这就是为什么隐藏最后一个按钮的原因，我想在清单文件中检查该特定布局的主题。如果你想要动作栏，你需要添加scrollview

Answer 2

Action bar is causing problem as in preview there is no Action bar..check this layout.

Answer 3

您的UI太大，设备无法呈现，请将您的布局包装在滚动视图中，以便在无法同时显示整个UI的设备上垂直滚动UI：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

//Put your layout here

</ScrollView>

将 ScrollView 放入 XML ，并在按钮上添加保证金底部
