我有5个正方形的瓷砖,所有这些瓷砖都必须具有相同的尺寸,但必须具有柔韧性,以便可以增长和缩小以适应不同的显示器尺寸。每个图块下方都有文字。我希望最后一行水平居中,并希望在可能的情况下仅使用xml。我也有一个工具栏和一个导航栏。这是我的xml文件:

尝试更改android:id="@+id/ivLearn"
的属性
来自
app:layout_constraintStart_toStartOf="@+id/ivGuide"
app:layout_constraintEnd_toEndOf="@+id/ivGuide"
到
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"

我还没有尝试过,但是回收站视图似乎是android团队最好和最灵活的答案。我使用了百分比形式的垂直指南,我需要在不同的屏幕尺寸上进行测试,这似乎至少可以在一个屏幕尺寸上使用。我还必须将Java代码转换为我正在学习的Kotlin。
谢谢。
