布局文件(activity_sms.xml)




    

一个简单的读取短信内容的例子(SMSActivity)

package com.example.administrator.myapplication;

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.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class SMSActivity extends AppCompatActivity {

    private ListView lv_sms_list;
    private List> data;
    private SimpleAdapter simpleAdapter;
    private ContentResolver contentResolver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sms);

        //获取访问者
        contentResolver = getContentResolver();

        lv_sms_list = (ListView) findViewById(R.id.lv_sms_list);
        data = new ArrayList>();
        //适配器
        simpleAdapter = new SimpleAdapter(this,data,android.R.layout.simple_list_item_2,new String[]{"names","note"},new int[]{android.R.id.text1,android.R.id.text2});
        lv_sms_list.setAdapter(simpleAdapter);
    }


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

        }
    }
}

最后需要在清单文件上配置读取短信的权限即可(AndroidManifest.xml)
