获取手机短信并显示

效果图如下：是用ListView显示的短信内容

一下是实现代码：
package com.example.android_contentresolver;

import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ListView;
import android.widget.SimpleAdapter;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class DuanxinActivity extends AppCompatActivity {

private ListView lv_duanxin;
private List list;
private SimpleAdapter simpleAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_duanxin);
    lv_duanxin = (ListView) findViewById(R.id.lv_duanxin);
    list = new ArrayList();
    simpleAdapter = new SimpleAdapter(this, list, android.R.layout.simple_list_item_2, new String[]{"date", "body"}, new int[]{android.R.id.text1, android.R.id.text2});
    lv_duanxin.setAdapter(simpleAdapter);
}
public void getDuanxin(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);//id
            address=cursor.getString(1);//电话号码
            body=cursor.getString(2);//短信内容
            date=cursor.getString(3);
            type=cursor.getInt(4);
            Log.i("test","_id="+_id+" address="+address+" body="+body+" date="+date+" type="+type);
            map.put("address",address);
            map.put("body",body);
            list.add(body);
    }
}

}
}
