在您的res/drawable中添加以下xml:
In your res/drawable add these xml:
mybutton.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="25dp" />
<solid android:color="#004D40" />
</shape>
mybutton2.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="25dp" />
<solid android:color="#FFA726" />
</shape>
stroke_button.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
<corners android:radius="20dp" />
<stroke
android:width="1dp"
