推荐答案
使用ConstraintLayout如下:
Use ConstraintLayout as below:
这是您的代码:your_layout.xml

形状可绘制:your_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#4588C0" />
<stroke
android:width="2dp"
android:color="#ffffff" />
</shape>
如果你想用白色显示按下/选择的按钮，那么你必须创建可绘制的选择器并将其放在按钮的背景中.
If you want to display pressed/selected button with white color then you have to create selector drawable and give it in background of button.
如果您不想提供静态垂直边距，请使用以下代码
