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

发送短息的主界面mian.xml和实现Activity    SendSMS.java

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 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;
    }
  }
}
