我正在尝试为我的ExpandableListView创建自定义背景选择器.它适用于除焦点以外的所有州.我无法确定当前关注哪一行.这是代码：
im_selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true"
android:drawable="@drawable/list_selector_background_focus" />
<item android:state_pressed="true"
android:drawable="@drawable/list_selector_background_pressed" />
<item
android:drawable="@drawable/list_bg" />
</selector>
我的列表视图在布局文件中
<ExpandableListView android:id="@+id/android:list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:scrollbars="horizontal"
android:layout_below="@id/top_bar"
android:layout_marginBottom="45px"
android:divider="#00000000"
android:cacheColorHint="#00000000"
android:listSelector="@layout/im_selector"
android:focusable="true"
/>
