android利用ContentResolver访问者获取手机短信信息

利用contentresolver访问者获取手机短信信息，在此记录一下，一遍以后查询。

首先看一下结果，结果如下：

activity_message.xml类:

 <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/activity_message"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 tools:context="com.example.android_25.messageactivity">
 <listview
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:id="@+id/lv_message"
  >
 </listview>
</linearlayout>

activity_xs.xml类

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/activity_xs"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 tools:context="com.example.android_25.xsactivity">
<textview
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:id="@+id/tv_name"
 />
 <textview
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:id="@+id/tv_telephone"
  />
</linearlayout>

messageactivity类：

public class messageactivity extends appcompatactivity {

 private listview lv_message;
 private contentresolver cr;
 private arraylist<map<string, object>> datalistview;

 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_message);
  //获得短信的id
  lv_message = (listview) findviewbyid(r.id.lv_message);
  //得到访问者contentresolver
  cr = getcontentresolver();
  //定义一个接收短信的集合
  datalistview = new arraylist<>();
  uri uri = uri.parse("content://sms/");
  cursor cursor = cr.query(uri, null, null, null, null);
  while (cursor.movetonext()) {
   string body = cursor.getstring(cursor.getcolumnindex("body"));
   int address = cursor.getint(cursor.getcolumnindex("address"));
   //将号码和短信内容放入map集合中
   map<string, object> map = new hashmap<>();
   map.put("images", address+"");
   map.put("titles", body);
   datalistview.add(map);
  }
  simpleadapter adapter = new simpleadapter(this, datalistview, r.layout.activity_xs, new string[]{"images", "titles"}, new int[]{r.id.tv_name, r.id.tv_telephone});
  lv_message.setadapter(adapter);
 }
}
