Answer 1

用它 - drawable/style_circular_button.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" >
        <shape android:shape="oval">
            <solid android:color="@color/colorDeepOrange"/>
            <size android:width="120dp" android:height="120dp"/>
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="oval">
            <solid android:color="@color/colorOrange"/>
            <size android:width="120dp" android:height="120dp"/>
        </shape>
    </item>
    <item >
        <shape android:shape="oval">
            <solid android:color="@color/colorOrange"/>
            <size android:width="120dp" android:height="120dp"/>
        </shape>
    </item>
</selector>

并将其设置style_circular_button.xml为背景Button-

<Button
   android:id="@+id/btnSignin"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="@string/text_btn_login"
   android:background="@drawable/style_circular_button"/>
