自定义SwitchCompat按钮的样式

先自定义中间的圆球switch_thumb_bg.xml

<?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="45dp"android:height="45dp" /><!-- 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>

然后自定义外部的椭圆

// switch_select_style.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"><item android:drawable="@drawable/switch_selected" android:state_checked="true" /><item android:drawable="@drawable/switch_unselected" android:state_checked="false" />
</selector>// switch_selected.xml
<?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="@color/home_color_sel" /><size android:height="40dp" /><corners android:radius="40dp" /><strokeandroid:width="1dp"android:color="@color/white" /></shape></item>
</layer-list>//switch_unselected.xml
<?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="#2e4044" /><size android:height="40dp" /><strokeandroid:width="1dp"android:color="@color/white" /><corners android:radius="40dp" /></shape></item>
</layer-list>

然后编写控件

   <androidx.appcompat.widget.SwitchCompatandroid:id="@+id/sc_auto"android:textColor="@color/white"android:text=" ON/OFF"android:thumb="@drawable/switch_thumb_bg"app:switchMinWidth="@dimen/common_height"app:track="@drawable/switch_select_style"android:layout_width="match_parent"android:layout_height="@dimen/common_height"/>

自定义radioButton的选择背景色

编写drawable的样式

//radio_sel_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"><item android:state_checked="false"><shape android:shape="rectangle"><solid android:color="#323f45" /><strokeandroid:width="1dp"android:color="@color/white" /><cornersandroid:radius="99dp"/></shape></item><item android:state_checked="true"><shape android:shape="rectangle"><solid android:color="@color/home_color_sel" /><strokeandroid:width="1dp"android:color="@color/white" /><cornersandroid:radius="99dp"/></shape></item>
</selector>

编写控件

 <RadioButtonandroid:id="@+id/rb1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:button="@color/transparent"android:background="@drawable/radio_sel_bg"android:gravity="center"android:text="1s"android:checked="true"android:textColor="@color/white" /><RadioButtonandroid:id="@+id/rb2"android:layout_width="wrap_content"android:layout_height="wrap_content"android:button="@color/transparent"android:background="@drawable/radio_sel_bg"android:gravity="center"android:text="1m"android:textColor="@color/white" />

然后编写拖动长条的样式

// bg_sb_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-listxmlns:android="http://schemas.android.com/apk/res/android"><item android:id="@android:id/background"><shape><-- 这里是拖动条右边的颜色 --><solid android:color="#2e4044" /></shape></item><item android:id="@android:id/secondaryProgress"><clip><shape><solid android:color="#FFFFFFFF" /></shape></clip></item><item android:id="@android:id/progress"><clip><shape><-- 这里是拖动条左边的颜色 --><solid android:color="#2e4044" /></shape></clip></item>
</layer-list>

编写控件

<SeekBarandroid:id="@+id/sb_brightness"android:layout_below="@+id/tv_music_num"android:layout_width="match_parent"android:layout_height="wrap_content"android:background="@color/transparent"android:maxHeight="10dp"android:minHeight="10dp"android:progress="50"android:max="255"android:min="0"android:thumb="@drawable/icon_seek_bg"android:progressDrawable="@drawable/bg_sb_bar"android:splitTrack="false" />
