Android利用ContentProvider读取短信内容

本文实例为大家分享了Android利用ContentProvider读取短信内容的具体代码,供大家参考,具体内容如下

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:

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" />
