原生的SwitchCompat控件如下图，不说不堪入目，也算是不敢恭维了。开个玩笑...

所以我们就需要对SwitchCompat进行自定义风格，效果如下图

代码如下

    <androidx.appcompat.widget.SwitchCompatandroid:id="@+id/switch_compat"android:layout_width="wrap_content"android:layout_height="wrap_content"android:thumb="@drawable/switch_thumb"app:switchMinWidth="60dp"app:track="@drawable/switch_track_style" />

从上面的xml代码来看其实只需要定制两个东西一个是thumb，另一个是track

switch_thumb

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"android:shape="oval"><solid android:color="@color/white" /><sizeandroid:width="50dp"android:height="50dp" /><!-- 这里的5dp边距的作用是，圆点在轨道里面的边距，这样的效果感觉更好 --><strokeandroid:width="5dp"android:color="#00000000" /><corners android:radius="15dp" />
</shape>

switch_track_style

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"><item android:drawable="@drawable/switch_common_track_selected" android:state_checked="true" /><item android:drawable="@drawable/switch_common_track_unselected" android:state_checked="false" />
</selector>

switch_track_style里面有两个背景如下

switch_common_track_selected

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"><item ><shape android:shape="rectangle"><solid android:color="#23c3ff" /><size android:height="30dp" /><strokeandroid:color="#00000000" /><corners android:radius="30dp" /></shape></item>
</layer-list>

switch_common_track_unselected

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"><item><shape android:shape="rectangle"><solid android:color="#4D8E8E8E" /><size android:height="30dp" /><strokeandroid:color="#00000000" /><corners android:radius="30dp" /></shape></item>
</layer-list>

完活了！！！
