Android ExpandableListView 进行二级扩展 （BaseExpandableListAdapter）

首先，我的这个这个加载界面是在Fragment里面添加的，可能和activity有点区别，但不是很大。

主要布局文件stream.xml，添加ExpandableListView控件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ExpandableListView
android:id="@+id/expandable"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>

第一个自定义菜单布局文件groups.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:layout_width="50dp"
android:layout_height="80dp"
android:id="@+id/ImageGroup"
/>
<TextView
android:id="@+id/textGroup"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:paddingLeft="40px"
android:paddingTop="6px"
android:paddingBottom="6px"
android:textSize="25sp"
android:text="No data"
android:layout_marginLeft="70dp"/>
</LinearLayout>

第二级自定义菜单布局childs.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:id="@+id/imageChild"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_gravity="left"/>
<TextView
android:id="@+id/textChild"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:paddingLeft="60px"
android:paddingTop="10px"
android:paddingBottom="10px"
android:textSize="20sp"
android:text="No Data"
android:layout_marginLeft="0dp"/>

</LinearLayout>

Fragment里面的文件和响应
