BroadcastRecever

##简介
注册分为静态注册和动态注册
静态注册是在xml中进行注册是常驻型的不随着程序的关闭而关闭
动态注册在代码中进行注册不是常驻型随着程序的关闭而关闭
###多个界面公用一个broadcastrecever

public abstract class MyBaseFragment extends Fragment {public static final String ACTION_1 = "com.example.action1";public static final String ACTION_2 = "com.example.action2";@Overridepublic void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(ACTION_1);intentFilter.addAction(ACTION_2);getActivity().registerReceiver(receiver, intentFilter);Intent intentserver  = new Intent(getActivity(),MyNotificationServer.class);getActivity().startService(intentserver);}protected abstract void doAction1();protected abstract void doAction2(String arg);BroadcastReceiver receiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();if (action.equals(ACTION_1)) {doAction1();} else if (action.equals(ACTION_2)) {String arg = intent.getStringExtra("arg");doAction2(arg);}}};@Overridepublic void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();getActivity().unregisterReceiver(receiver);}}

 @Overrideprotected void doAction1() {// TODO Auto-generated method stub}@Overrideprotected void doAction2(String arg) {// TODO Auto-generated method stubLog.d("tag", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"+arg);if (arg.equals("1")) {Log.d("tag", arg);handler.sendEmptyMessage(MyConfig.UPDATA_TOKEN_WFJ);

Intent intent = new Intent();intent.setAction(MyBaseFragment.ACTION_1);intent.setAction(MyBaseFragment.ACTION_2);intent.putExtra("arg","1");sendBroadcast(intent);

####MyReceiver extends BroadcastReceiver

public class Reciever extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {Toast.makeText(context,"我收到了广播",Toast.LENGTH_SHORT).show();Log.d("TAG", "闹钟");}
}

####MainActivity

public class MainActivity extends Activity {private Button mButtonSend;private Reciever mReciever;private AlarmManager mAlarmManager;private Button mButtonAlarm;private Button mButtonStopAlarm;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mAlarmManager= (AlarmManager) getSystemService(Context.ALARM_SERVICE);mReciever=new Reciever();IntentFilter filter=new IntentFilter();filter.addAction("com.lingzhuo");registerReceiver(mReciever,filter);//注册接收ID号mButtonSend= (Button) findViewById( R.id.button_send);mButtonSend.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent intent=new Intent();intent.setAction("com.lingzhuo");sendBroadcast(intent);}});mButtonAlarm= (Button) findViewById(R.id.button_alarm);mButtonAlarm.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent intent1=new Intent();intent1.setAction("com.lingzhuo");PendingIntent pendingIntent=PendingIntent.getBroadcast(getApplicationContext(),0x23,intent1,PendingIntent.FLAG_UPDATE_CURRENT);mAlarmManager.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis()+3000,3000,pendingIntent);Log.d("TAG", "asdasdasdas");}});mButtonStopAlarm= (Button) findViewById(R.id.button_alarm_stop);mButtonStopAlarm.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent intent=new Intent();intent.setAction("com.lingzhuo");PendingIntent pendingIntent=PendingIntent.getBroadcast(getApplicationContext(),0x23,intent,PendingIntent.FLAG_UPDATE_CURRENT);mAlarmManager.cancel(pendingIntent);}});}
//注册ID以后必须要销毁不然会报错@Overrideprotected void onDestroy() {super.onDestroy();unregisterReceiver(mReciever);}
}
