使用broadcastreceiver监听短信

最近接的一个小项目，监听短信，如果短信中包含某字符串（比如“#回复码”），则自动回复内容。

功能很简单，就涉及到两块知识点：broadcastreceiver的静态动态注册和短信类的使用。

项目的完成参考的此篇博客：http://blog.csdn.net/mad1989/article/details/22426415

先说说broadcastreceiver的注册问题：

1、静态注册：

        <receiver android:name="jianghuai.automessage.MsgReceiver" >            <intent-filter android:priority="999" >                <action android:name="android.provider.Telephony.SMS_RECEIVED" />            </intent-filter>        </receiver>

静态注册很简单，在AndroidManifest.xml配置文件中添加receiver标签，并设置其filter为

"android.provider.Telephony.SMS_RECEIVED"

剩下的就是写一个Receiver类，并重写onReceive方法。

2、动态注册：

动态注册就是在activity中动态对receiver进行注册。

//动态注册broadcastreceivermsgReceiver = new MsgReceiver();IntentFilter filter = new IntentFilter();filter.addAction("android.provider.Telephony.SMS_RECEIVED");MainActivity.this.registerReceiver(msgReceiver, filter);

如上面的示例代码，一个IntentFilter类和一个写好的Receiver类，通过filter.addAction将需要监听的内容添加进来，并调用registerReceiver来进行注册。

动态注册还需要注意在activity中还需要动态注销，如下

@Overrideprotected void onDestroy() {super.onDestroy();MainActivity.this.unregisterReceiver(msgReceiver);}

在activity中的onDestroy方法中，调用unregisterReceiver方法来注销receiver。

短信类的使用：SmsMessage类

java.lang.Object   ↳android.telephony.SmsMessage

常用的几个方法：

getOriginatingAddress() 获得发来短信的号码

getDisplayMessageBody 获得短信内容

getTimestampMillis 获得短信时间

另外这个小项目中，用到了SharedPreferences类来对数据进行持久化。

将数据存入SharedPreferences。

sharedPreferences = getSharedPreferences("autoMsg",Context.MODE_PRIVATE);Editor editor = sharedPreferences.edit();

editor.putString("custom_submsg", submsg);editor.putString("custom_reply", auto_reply);editor.commit();

从SharedPreferences取出数据：

sharedPreferences = context.getSharedPreferences("autoMsg",Context.MODE_PRIVATE);submsg = sharedPreferences.getString("custom_submsg", "");

最后贴下完整的代码：

MainActivity

The action bar will// automatically handle clicks on the Home/Up button, so long// as you specify a parent activity in AndroidManifest.xml.int id = item.getItemId();if (id == R.id.action_settings) {return true;}return super.onOptionsItemSelected(item);}}
