ExpandableListView 设置子节点分隔线颜色

首先创建一个child_bg.xml

<?xml version="1.0" encoding="utf-8"?>

<layer-list

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

<item>

<shape>

<gradient

android:startColor="#000000"

android:centerColor="#CCCCCC"

android:endColor="#FFFFFF"

android:height="1px"

android:angle="0" />

</shape>

</item>

</layer-list>

//然后ExpandableListView里把颜色赋值给android:childDivider="@drawable/child_bg"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@color/common_bg">

<ExpandableListView
android:id="@+id/expandableListView_plJTG"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="false"
android:divider="#FFCECFCE"
android:dividerHeight="1.0dp"
android:fadingEdge="vertical"
android:childDivider="@drawable/child_bg"
android:cacheColorHint="#00000000"
android:background="@color/common_bg">
</ExpandableListView>

</LinearLayout>
