llOptionsContainer的布局如下：

<LinearLayout

android:id="@+id/ll_feedback_options_parent"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginTop="12dp"

android:background="@color/gray_f"

android:orientation="vertical" >

</LinearLayout>

radioButton 的样式selector：

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

<item android:drawable="@drawable/fuli_choose_grey" android:state_checked="false"/>

<item android:drawable="@drawable/fuli_choose_red" android:state_checked="true"/>

</selector>

由于时间关系就不封装了，可以自己自定义方式进行封装
