在我的应用程序中,我有一个实现计时器任务的服务,通过它我每 10 秒后获取用户的位置。
我坚持的事情是我想在 1 或 2 分钟后停止这项服务以及计时器。
我不能把它的逻辑放在后面。请帮帮我。
public class TimeService extends Service {
// constant
public static final long NOTIFY_INTERVAL = 20 * 1000; // 10 seconds
// run on another Thread to avoid crash
private Handler mHandler = new Handler();
// timer handling
private Timer mTimer = null;
int i=0;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
// cancel if already existed
if(mTimer != null) {
mTimer.cancel();
} else {
// recreate new
mTimer = new Timer();
}
// schedule task
mTimer.scheduleAtFixedRate(new TimeDisplayTimerTask(), 0, NOTIFY_INTERVAL);
}
class TimeDisplayTimerTask extends TimerTask {
@Override
public void run() {
// run on another thread
mHandler.post(new Runnable() {
@Override
public void run() {
// display toast
Toast.makeText(getApplicationContext(), getDateTime(),
Toast.LENGTH_SHORT).show();
new LongOperation().execute("");
}
});
}
private String getDateTime() {
// get date time in custom format
SimpleDateFormat sdf = new SimpleDateFormat("[yyyy/MM/dd - HH:mm:ss]");
return sdf.format(new Date());
}
}
private class LongOperation extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
System.out.println("bgnotification Long operation doinbackground called----> ");
return "";
}
@Override
protected void onPostExecute(String result) {
System.out.println("bgnotification Long operation post execute called----> ");
if(i<3){
GPSTracker mGPS = new GPSTracker(getApplicationContext());
onLocationChanged(mGPS);i++;
Toast.makeText(getApplicationContext(), "HEllo Post execute called",
}
@Override
protected void onPreExecute() {
System.out.println("bgnotification Long operation pre execute called----> ");
}
@Override
protected void onProgressUpdate(Void... values) {
}
}
public void onLocationChanged(GPSTracker track) {
// Getting latitude
double latitude = track.getLatitude();
// Getting longitude
double longitude = track.getLongitude();
System.out.println( latitude);
System.out.println( longitude);
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try
{
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
Log.e("Addresses","-->"+addresses);
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
