通过ContentProvider实现获取手机中的短息内容

以下是我通过ContentProvider实现的获取的手机中的短息内容和发送人的电话号码，通过ListView遍历了短信的内容

首先展示下获取的短信内容

在清单文件中配置获取的短信的权限

    <uses-permission android:name="android.permission.READ_SMS">uses-permission>
    <uses-permission android:name="android.permission.WRITE_SMS">uses-permission>

activity_message.xml

<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.g150825_resolver.MessageActivity">
  <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:onClick="readSMS"
      android:text="读取手机短信"
      />

  <ListView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:id="@+id/lv_main_list"
      >
  ListView>

MessageActivity.java

public class MessageActivity extends AppCompatActivity {

    private ListView lv_main_list;
    private SimpleAdapter sa;
    private List> data;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_message);
        //得到ListView
        lv_main_list = (ListView) findViewById(R.id.lv_main_list);

        data =new ArrayList>();
       //配置适配置器S
        sa = new SimpleAdapter(this,data,android.R.layout.simple_list_item_2,new String[]{"names","message"},new int[]{android.R.id
                .text1,android.R.id.text2});
        lv_main_list.setAdapter(sa);
    }
    public void readSMS(View view) {
        //读取所有短信
        Uri uri=Uri.parse("content://sms/");
        ContentResolver resolver = getContentResolver();
        Cursor cursor = resolver.query(uri, new String[]{"_id", "address", "body", "date", "type"}, null, null, null);
        if(cursor!=null&&cursor.getCount()>0){
            int _id;
            String address;
            String body;
            String date;
            int type;
            while (cursor.moveToNext()){
                Map map=new HashMap();
                _id=cursor.getInt(0);
                address=cursor.getString(1);
                body=cursor.getString(2);
                date=cursor.getString(3);
                type=cursor.getInt(4);
                map.put("names",body);

                Log.i("test","_id="+_id+" address="+address+" body="+body+" date="+date+" type="+type);
                data.add(map);
                //通知适配器发生改变
                sa.notifyDataSetChanged();
            }
        }
    }
}
