首先，我们来看下运行效果
运行效果如下：

展示短信内容的效果如下：
这里写图片描述

布局文件（activity_sms.xml）

<?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_sms"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:orientation="vertical"    tools:context="com.example.administrator.myapplication.SMSActivity">    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="获取手机所有的短信内容"        android:onClick="getContactsSms"        />    <ListView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/lv_sms_list"        ></ListView></LinearLayout>

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<Map<String,Object>> 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<Map<String,Object>>();        //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()){                Map<String,Object>map=new HashMap<String,Object>();                _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）

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