我正在做一個應用程序來檢查現場比分。我不知道這是否是最好的方法,但我創建了一個Timertask,一個Service和Activity來通知。每x秒發送一次通知
Timertask每x秒檢查一次分數是否發生變化,如果發生變化,則通知服務。 如果通知服務,它會調用將通知用戶的活動。我的問題是我沒有打電話給該服務通知活動。
這裏是我的代碼(本例中,我沒拿分數,但一個變量i。
//import ...
public class MyService extends Service{
Notif notif = new Notif();
private static final String TAG = "MyService";
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
Toast.makeText(this, "Congrats! MyService Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
}
@Override
public void onStart(Intent intent, int startId) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
Timer time = new Timer(); // Instantiate Timer Object
final ScheduleTask st = new ScheduleTask(); // Instantiate SheduledTask class
time.schedule(st, 0, 5000); // Create Repetitively task for every 1 secs
}
@Override
public void onDestroy() {
Toast.makeText(this, "MyService Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
}
public void checkI(int i){
if (i==3){
notif.initializeUIElements();
}
}
}
的TimerTask
import ...
// Create a class extends with TimerTask
public class ScheduleTask extends TimerTask {
MyService myService = new MyService();
Notif notif = new Notif();
int i = 0;
// Add your task here
public void run() {
i++;
System.out.println("affichage numero " + i);
myService.checkI(i);
}
public int getI() {
return i;
}
}
NOTIF
import ...
public class Notif extends Activity {
private static final int NOTIFY_ME_ID = 1987;
private NotificationManager mgr = null;
ScheduleTask scheduleTask = new ScheduleTask();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
}
void initializeUIElements() {
Notification note = new Notification(R.drawable.ic_launcher,
"Welcome to MyDoople.com", System.currentTimeMillis());
PendingIntent i = PendingIntent.getActivity(this, 0, new Intent(
this, MainActivity.class), Notification.FLAG_ONGOING_EVENT);
note.setLatestEventInfo(this, "MyDoople.com", "An Android Portal for Development",
i);
// note.number = ++count;
note.flags |= Notification.FLAG_ONGOING_EVENT;
mgr.notify(NOTIFY_ME_ID, note);
}
}
