ExpandableListView 是一个可以实现下拉列表的控件，大家可能都用过QQ，QQ中的好友列表就是用ExpandableListView实现的，不过它是自定义的适配器。本篇博客除了要介绍ExpandableListView的使用，还整合了获取SIM的状态，这个很简单也就是获取系统服务，再调用相应的方法就可以实现，在这里只是记录一下。

本篇博客要实现效果图如下：

除了子列表不怎么好看之外，组列表还是蛮好看的，这里只是为了演示，子列表就没做特别的处理。

布局文件：

/SIM_Card_Demo/res/layout/inbox.xml

组列表项

/SIM_Card_Demo/res/layout/group_item.xml

子列表项
/SIM_Card_Demo/res/layout/child_item.xml

<?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="@drawable/item_bg"
> <TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#ffff0000"
android:text="SIM卡状态:" /> <TextView
android:id="@+id/tv_sim_status"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#ff00ff00"
android:text="@string/app_name" /></LinearLayout>

自定义适配器（重要）
