结果如下：

这里写图片描述

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);    }}
