android广播（内部类）使用

1.广播定义在一个单独的文件中

源码：

public class MessageReceiver extends BroadcastReceiver{@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif(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{@Overridepublic 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～～
