我有通知,点击通知应该使用intent设置值。此值应在其他"活动"的BroadcastReceiver中接收。有什么帮助吗?下面是我的代码:
public void showNotification(){
Intent intent = new Intent(MainActivity.ACTION_NEW_MSG);
intent.putExtra(MainActivity.MSG_FIELD, "TEST VALUES");
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
ComponentName cn = new ComponentName(getApplicationContext(), MainActivity.class);
intent.setComponent(cn);
sendBroadcast(intent);
contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
notification = new NotificationCompat.Builder(getApplicationContext())
.setCategory(Notification.CATEGORY_PROMO)
.setContentTitle("TEST VALUE")
.setContentText("Please click for")
.setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(false)
.setVisibility(1)
.setSubText("Time left: " + millisUntilFinished/1000)
.addAction(android.R.drawable.ic_menu_view, "View details", contentIntent)
.setContentIntent(contentIntent)
.setPriority(Notification.PRIORITY_HIGH)
.setVibrate(new long[]{0}).build();
notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
int notification_id = 666;
notificationManager.notify(notification_id, notification);
}
及以下主要活动:
private void initReceiver() {
myReceiver = new MyReceiver();
IntentFilter filter = new IntentFilter(ACTION_NEW_MSG);
registerReceiver(myReceiver, filter);
}
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_NEW_MSG)) {
String message = intent.getStringExtra(MSG_FIELD);
Toast.makeText(getApplicationContext(),message, Toast.LENGTH_LONG).show();
Log.e("TESTING", "TESTING");
}
}
}
为什么不使用服务而不是接收器?您可以创建这样的意图:Intent i = new Intent(MainActivity.this, MyService.class);
你可以在意图中加入额外的内容和动作。在服务类中,只需覆盖此功能:
@Override
public int onStartCommand(Intent intent, int flags, int startId){
if (intent != null) {
final String action = intent.getAction();
}
}
