Android开发获取短信的内容并截取短信

1、首先我们要写一个广播接收器，当我们的手机收到短信时，系统会自动发送一个广播，我们只需要接收到这条广播就可以了

2、在广播里面，我们重写的onreceive（）方法，通过里面的intent写到的bundle就可以拿到短信的内容，

3、清单文件里面我们必须要添加权限，否则无法接收到。

4、为了防止我们的广播接收不到，我们自己写的广播接收器的权限必须要大，以防万一，我设置了1000。

下面上代码，里面的注释也比较详细..

 <?xml version="." encoding="utf-"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.fanlei.cutnotedemo" >
   //接收短信
   <uses-permission android:name="android.permission.receive_sms"/>
   <application
     android:allowbackup="true"
     android:icon="@drawable/ic_launcher"
     android:label="@string/app_name"
     android:theme="@style/apptheme" >
     <!-- action:name = 的名称是固定的 -->
     <receiver android:name=".notereceiver">
       <intent-filter android:priority="">
         <action android:name="android.provider.telephony.sms_received"/>
       </intent-filter>
     </receiver>
     <activity
       android:name=".mainactivity"
       android:label="@string/app_name" >
       <intent-filter>
         <action android:name="android.intent.action.main" />
         <category android:name="android.intent.category.launcher" />
       </intent-filter>
     </activity>
   </application>
 </manifest>

写一个类，继承broadcastreceiver

android--获取短信的内容，截取短信
 package com.example.fanlei.cutnotedemo;
 import android.content.broadcastreceiver;
 import android.content.context;
 import android.content.intent;
 import android.os.bundle;
 import android.telephony.smsmessage;
 import android.widget.toast;
 import java.text.simpledateformat;
 import java.util.date;
 /**
 * 广播接收器
 */
 public class notereceiver extends broadcastreceiver {
   private static final string sms_received_action = "android.provider.telephony.sms_received";
   @override
   public void onreceive(context context, intent intent) {
     string action = intent.getaction();
     //判断广播消息
     if (action.equals(sms_received_action)){
       bundle bundle = intent.getextras();
       //如果不为空
       if (bundle != null){
         //将pdus里面的内容转化成object[]数组
         object pdusdata[] = (object[]) bundle.get("pdus");
         //解析短信
         smsmessage[] msg = new smsmessage[pdusdata.length];
         for (int i = ;i < msg.length;i++){
           byte pdus[] = (byte[]) pdusdata[i];
           msg[i] = smsmessage.createfrompdu(pdus);
         }
         stringbuffer content = new stringbuffer();//获取短信内容
         stringbuffer phonenumber = new stringbuffer();//获取地址
         stringbuffer receivedata = new stringbuffer();//获取时间
         //分析短信具体参数
         for (smsmessage temp : msg){
           content.append(temp.getmessagebody());
           phonenumber.append(temp.getoriginatingaddress());
           receivedata.append(new simpledateformat("yyyy-mm-dd hh:mm:ss.sss")
               .format(new date(temp.gettimestampmillis())));
         }
         /**
         * 这里还可以进行好多操作，比如我们根据手机号进行拦截（取消广播继续传播）等等
         */
         toast.maketext(context,phonenumber.tostring()+content+receivedata, toast.length_long).show();//短信内容
       }
     }
   }
 }

ps：android获取短信所有内容

public class getmessageinfo {
