在我的应用程序中,我有一个包含一个简单容器(LinearLayout)的“活动”,我想在其中显示片段。一切正常,片段显示出来,但在屏幕末尾有点“切断”。这意味着如果片段中的屏幕完全被按钮填充,则在实际运行的应用程序中,最后一个按钮没有或仅部分显示。
为了便于测试,我创建了这个新项目,其中片段中只有3个大按钮,在android studio的设计功能中,这些按钮不会扩展屏幕,但是当我运行它时,它会被切断。 / p>

我有99%的把握要确保您的视图不适合您的屏幕,因为视图上的文本尺寸很大(100dp
),较大的文本尺寸会调整视图的尺寸,并且您使用固定的尺寸你发短信的大小。
请记住,固定的视图尺寸会使布局无响应
我从视图中删除了您的文本大小之后,下面是一个示例:
<?xml version="1.0" encoding="utf-8"?>

如果您想使用大字体,则可以使用Autosizing TextViews
