Android broadcast (internal class) Usage

1. Broadcast is defined in a separate file

Source code:

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")){}}}

Register in manifest:

<receiver android:name=".MessageReceiver">            <intent-filter>                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>            </intent-filter></receiver>

Use the code to register:

// Generate messagereceiver smsbroadcastreceiver = new messagereceiver (); // instantiate the filter and set the broadcast intentfilter = new intentfilter (); intentfilter. addaction ("android. provider. telephony. sms_received "); // register broadcast this. registerreceiver (smsbroadcastreceiver, intentfilter );

Cancel broadcast:

unregisterReceiver(smsBroadCastReceiver);

2. Broadcast is an internal class

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");    }}}

Note that it must be declared as static during the definition process, otherwise it will not be found

Register in manifest:

<receiver android:name=".SettingForSMS$MessageChangeReceiver">            <intent-filter>                <action android:name="com.ginwave.message_changed"/>            </intent-filter></receiver>

Note that the internal class uses the $ symbol instead of the. symbol. If you use the. symbol, the class cannot be found.

Register in the program. The register is placed in oncreate, And the unregister is placed in ondestroy.

Smsbroadcastreceiver = new messagechangereceiver (); // instantiate the filter and set the broadcast intentfilter = new intentfilter (); intentfilter. addaction ("com. ginwave. message_changed "); // register broadcast this. registerreceiver (smsbroadcastreceiver, intentfilter );

unregisterReceiver(smsBroadCastReceiver);

I hope it will be easier to use it later ~~
