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" />
