Android 下实现程序关闭后监听取消

核心提示:StringBuilder sb = new StringBuilder();Bundle bundle = intent.getExtras();if (bundle != null) {Object[] pdus = (Object[]) bundle.get("pdus");SmsMessag

StringBuilder sb = new StringBuilder();

Bundle bundle = intent.getExtras();

if (bundle != null) {

Object[] pdus = (Object[]) bundle.get("pdus");

SmsMessage[] msg = new SmsMessage[pdus.length];

for (int i = 0; i < pdus.length; i++) {

msg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);

}

for (SmsMessage currMsg : msg) {

sb.append("From:");

sb.append(currMsg.getDisplayOriginatingAddress());

sb.append(" Message:");

sb.append(currMsg.getDisplayMessageBody());

}

}

Intent i = new Intent(SvrId);

i.putExtra("PARAM", sb.toString());

sendBroadcast(i);

}

}

}

}

可以看到,前文中接收短信的代码被原封不动的复制到服务的代码内,唯一不同的就是服务中多了sendBroadcast()

二、修改BroadcastReceiver

package com.demo;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.widget.Toast;

public class MessageReceiver extends BroadcastReceiver {

public static final String SvrId = "RARNU.SERVICE.DEMO";

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().toString().equals(SvrId)) {

Bundle bund = intent.getExtras();

String strParam = "";

if (bund != null) {

strParam = bund.getString("PARAM");

}

Intent i = new Intent(context, MsgListen.class);

i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Toast.makeText(context, strParam, Toast.LENGTH_SHORT).show();

context.startActivity(i);

}

}

}

收短信的代码被移到服务中了,那么BroadcastReceive自然也不再需要那段代码,直接从Extras中取得服务传来的字符串即可。
