我怎么能每5秒在onCreate上循环那个time()函数..帮我在
android =)中新手我想在onCreate中每隔5秒执行一次time()函数.
- public void onCreate(Bundle savedInstanceState) {
- time(); //<-- How can i execute this every 5 seconds.
- }
- private void time() {
- new Handler().postDelayed(new Runnable() {
- @Override
- public void run() {
- int success;
- gps = new GPSTracker(AdminMenu.this);
- if(gps.canGetLocation()){
- tmplat=latitude;
- tmplong=longitude;
- // new InsertUser1().execute();
- }
- else{
- gps.showSettingsAlert();
- }
- try {
- Thread.sleep(5000);
- } catch (InterruptedException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- }
- System.out.println("LATTTTT" + tmplat);
- System.out.println("LONGGGGGGGG" + tmplong);
- }
- },5000); // 5 sec
- }
任何帮助都会被批评..
解决方法@H_404_8@
试着这样做！只需在startTimer方法中替换您的代码.它应该工作..
- private Timer timer;
- private TimerTask timerTask;
- private Handler handler = new Handler();
-
- //To stop timer
- private void stopTimer(){
- if(timer != null){
- timer.cancel();
- timer.purge();
- }
- }
-
- //To start timer
- private void startTimer(){
- timer = new Timer();
- timerTask = new TimerTask() {
- public void run() {
- handler.post(new Runnable() {
- public void run(){
- //your code is here
- }
- });
- }
- };
- timer.schedule(timerTask,5000,5000);
- }
- private Timer timer;
- private TimerTask timerTask;
- private Handler handler = new Handler();
- //To stop timer
- private void stopTimer(){
- if(timer != null){
- timer.cancel();
- timer.purge();
- }
- }
- //To start timer
- private void startTimer(){
- timer = new Timer();
- timerTask = new TimerTask() {
- public void run() {
- handler.post(new Runnable() {
- public void run(){
- //your code is here
- }
- });
- }
- };
- timer.schedule(timerTask,5000,5000);
- }
