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

<!--读取手机短信权限-->
<uses-permission android:name="android.permission.READ_SMS"></uses-permission>
<uses-permission android:name="android.permission.WRITE_SMS"></uses-permission>

activity_message.xml

<?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_message"

android:orientation="vertical"
tools:context="com.example.g150825_resolver.MessageActivity">
<Button

android:layout_height="wrap_content"

/>

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

</ListView>

</LinearLayout>

MessageActivity.java

package com.example.g150825_resolver;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
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 MessageActivity extends AppCompatActivity {

private ListView lv_main_list;
private SimpleAdapter sa;
private List<Map<String, Object>> 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<Map<String,Object>>();
//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<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);

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();
}
}
}
}

以上是简单的获取手机短信内容的代码，有其他意见的，可以一起交流
