CheckBox自定义样式

android:drawableStart="@drawable/sel_select"
android:button="@null"

此处不要使用background, 否则padding失效

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@mipmap/batch_operate_option_s" android:state_checked="true"/>
    <item android:drawable="@mipmap/batch_operate_option_n"/>
</selector>
