android广播（内部类）使用

1.广播定义在一个单独的文件中

源码：

1. public class MessageReceiver extends BroadcastReceiver{
2. @Override
3. public void onReceive(Context context, Intent intent) {
4. // TODO Auto-generated method stub
5. if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
6. }
7. }
8. }

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：

1. <receiver android:name=".MessageReceiver">
2. <intent-filter>
3. <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
4. </intent-filter>
5. </receiver>

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

使用代码注册：

1. //生成广播处理
2. MessageReceiver  smsBroadCastReceiver = new MessageReceiver ();
3. //实例化过滤器并设置要过滤的广播
4. IntentFilter intentFilter = new IntentFilter();
5. intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
6. //注册广播
7. this.registerReceiver(smsBroadCastReceiver, intentFilter);

//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：

1. unregisterReceiver(smsBroadCastReceiver);

unregisterReceiver(smsBroadCastReceiver);

2.广播是内部类

1. public class SettingForSMS extends PreferenceActivity{
2. @Override
3. public void onCreate(Bundle savedInstanceState) {
4. super.onCreate(savedInstanceState);
5. addPreferencesFromResource(R.layout.sms_setting);
6. }
7. public static class MessageChangeReceiver extends BroadcastReceiver {
8. @Override
9. public void onReceive(Context context, Intent intent) {
10. // TODO Auto-generated method stub
11. Log.i(tag, "onReceive");
12. }
13. }
14. }

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：

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

<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。

1. smsBroadCastReceiver = new MessageChangeReceiver ();
2. //实例化过滤器并设置要过滤的广播
3. IntentFilter intentFilter = new IntentFilter();
4. intentFilter.addAction("com.ginwave.message_changed");
5. //注册广播
6. this.registerReceiver(smsBroadCastReceiver, intentFilter);

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); 

1. unregisterReceiver(smsBroadCastReceiver);

unregisterReceiver(smsBroadCastReceiver);

希望以后使用的时候方便点～～
