源码：

public class MessageReceiver extends BroadcastReceiver{

	@Override

	public void onReceive(Context context, Intent intent) {

		// TODO Auto-generated method stub

		if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){

		}

	}

}

在Manifest中注册：

<receiver android:name=".MessageReceiver">

            <intent-filter>

                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>

            </intent-filter>

</receiver>

使用代码注册：

//生成广播处理

MessageReceiver  smsBroadCastReceiver = new MessageReceiver ();

//实例化过滤器并设置要过滤的广播

IntentFilter intentFilter = new IntentFilter();

intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");  

//注册广播

this.registerReceiver(smsBroadCastReceiver, intentFilter);  

注销广播：

unregisterReceiver(smsBroadCastReceiver);

2.广播是内部类

public class SettingForSMS extends PreferenceActivity{

	@Override

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		addPreferencesFromResource(R.layout.sms_setting);

	}

	public static class MessageChangeReceiver extends BroadcastReceiver {

	    @Override

	    public void onReceive(Context context, Intent intent) {

	        // TODO Auto-generated method stub

	        Log.i(tag, "onReceive");

	    }

	}

}

注意定义的过程中必须声明为static，不然会找不到

在Manifest中注册：

<receiver android:name=".SettingForSMS$MessageChangeReceiver">

            <intent-filter>

                <action android:name="com.ginwave.message_changed"/>

            </intent-filter>

</receiver>

注意内部类使用$符号而不是.，使用.会出现类找不到异常

在程序内注册，register是放在onCreate中，unregister是放在onDestroy中。

smsBroadCastReceiver = new MessageChangeReceiver ();

		//实例化过滤器并设置要过滤的广播

		IntentFilter intentFilter = new IntentFilter();

		intentFilter.addAction("com.ginwave.message_changed");  

		//注册广播

		this.registerReceiver(smsBroadCastReceiver, intentFilter); 

unregisterReceiver(smsBroadCastReceiver);

希望以后使用的时候方便点～～
