详解Android短信的发送和广播接收实现短信的监听

本文介绍了android短信的发送和广播接收者实现短信的监听，要注意android清单中权限的设置以及广播的注册监听实现，废话不多说，代码如下：

以下就是 android清单的xml

androidmanifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.zyw.broadcastsendsms"
  android:versioncode="1"
  android:versionname="1.0" >

  <uses-sdk
    android:minsdkversion="8"
    android:targetsdkversion="15" />

  <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/apptheme" >
    <activity
      android:name=".sendsms"
      android:label="@string/title_activity_send_sms" >
      <intent-filter>
        <action android:name="android.intent.action.main" />

        <category android:name="android.intent.category.launcher" />
      </intent-filter>
      
    </activity>
    <receiver android:name=".smsbroadcastreceiver">
      <intent-filter android:priority="1000">
        <action android:name="android.provider.telephony.sms_received"/>
      </intent-filter>
    </receiver>
    
  </application>
  <uses-permission android:name="android.permission.send_sms"></uses-permission><!--添加权限-->
  <uses-permission android:name="android.permission.receive_sms"></uses-permission> 
  <uses-permission android:name="android.permission.read_sms"></uses-permission> 
</manifest>

发送短息的主界面mian.xml和实现activity    sendsms.java

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  android:padding="10sp" >

  <textview
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="手机号码" />

  <edittext
    android:id="@+id/number"
    android:numeric="integer"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="请输入电话号码" />

  <textview
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="短信内容" />

  <edittext
    android:id="@+id/content"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="请输入短信内容"
    android:lines="3" />

  <textview
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >
  </textview>

  <button
    android:id="@+id/btnsend"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:paddingtop="20sp"
    android:text="发送短信" 
    android:onclick="send"
    />
 

</linearlayout>

实现activity 
sendsms.java

package com.zyw.broadcastsendsms;

import java.util.arraylist;

import android.app.activity;
import android.os.bundle;
import android.telephony.smsmanager;
import android.view.view;
import android.widget.edittext;
import android.widget.toast;

public class sendsms extends activity{
  private edittext num;
  private edittext content;
  
  @override
  public void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.main);
    num=(edittext) findviewbyid(r.id.number);
    content=(edittext) findviewbyid(r.id.content);
  }
  
  public void send(view view ) {
    string strno=num.gettext().tostring();
    string strcontent=content.gettext().tostring();
    
    smsmanager smsmanager = smsmanager.getdefault();
    //如果字数超过5,需拆分成多条短信发送
    if (strcontent.length() > 5) {
      arraylist<string> msgs = smsmanager.dividemessage(strcontent);
      for (string msg : msgs) {
        smsmanager.sendtextmessage(strno, null, msg, null, null);            
      }
    } else {
      smsmanager.sendtextmessage(strno, null, strcontent, null, null);
    }
    num.settext("");
    content.settext("");
    
    toast.maketext(sendsms.this, "短信发送完成", toast.length_long).show();
  }
}

广播接收者实现短信的监听  smsbroadcastreceiver.java

package com.zyw.broadcastsendsms;

import java.text.simpledateformat;
import java.util.date;
import android.content.broadcastreceiver;
import android.content.context;
import android.content.intent;
import android.os.bundle;
import android.telephony.smsmessage;
import android.widget.toast;

public class smsbroadcastreceiver extends broadcastreceiver {
  public void onreceive(context context, intent intent) {
    smsmessage msg = null;
      bundle bundle = intent.getextras();
      if (bundle != null) {
        object[] pdusobj = (object[]) bundle.get("pdus");
        for (object p : pdusobj) {
          msg= smsmessage.createfrompdu((byte[]) p);
          
          string msgtxt =msg.getmessagebody();//得到消息的内容
          
          date date = new date(msg.gettimestampmillis());//时间
          simpledateformat format = new simpledateformat("yyyy-mm-dd hh:mm:ss");
          string receivetime = format.format(date);
          
          string sendernumber = msg.getoriginatingaddress();
        
        if (msgtxt.equals("testing!")) {
          toast.maketext(context, "success!", toast.length_long)
              .show();
          system.out.println("success!");
          return;
        } else {
          toast.maketext(context, msgtxt, toast.length_long).show();
          system.out.println("发送人："+sendernumber+" 短信内容："+msgtxt+"接受时间："+receivetime);
          return;
        }
      }
      return;
    }
  }
}
