CheckedTextView 注意事项

设置选着框的样式：
selector必须要使用drawable,不能使用color，否者会报xml错误

//incompetence_item_selector  xml名称
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/uncheck" android:state_enabled="true" android:state_focused="true" android:state_pressed="false" />
    <item android:drawable="@drawable/check" android:state_enabled="true" android:state_pressed="true"  />
    <item android:drawable="@drawable/check" android:state_checked="true" android:state_enabled="true" />
    <item android:drawable="@drawable/uncheck" />

</selector>

    <CheckedTextView
        android:id="@+id/incompetence_item_ctv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:button="@null"
        android:ellipsize="marquee"
        android:filterTouchesWhenObscured="true"
        android:focusableInTouchMode="true"
        android:gravity="center_vertical"
        android:padding="@dimen/padding_size_two"
        android:text="CheckedTextView 注意事项" />

设置背景的selector一定要在代码里面设置，不能再xml中设置：

incompetence_item_ctv?.setCheckMarkDrawable(R.drawable.incompetence_item_selector)
