postdelayed

final Handler handler = new Handler(); LOG.d("delay"); handler.postDelayed(new Runnable() { @Override public void run() { LOG.d("notify!"); //calling some methods here } }, 2000); The "delay" does shows in the log, but not others at all. And the method called in the run() is not called at all also. Can anyone help explain why this happens, am I doing anything wrong? The class that has this code extends IntentService, will this be a problem? ============================ UPDATE: I put this code in the class that extends IntentService . The only place I found it worked was in the constructor. But

I used postedDelayed method to refresh my Activity, which works fine. But the problem is that even when I press the Back button postdelayed method call back the previous activity.. //handler for 30000 milli-secs post delay refreshment of the activity mHandler.postDelayed(new Runnable() { public void run() { dostuff(); } }, 30000); } protected void dostuff() { Intent intent = getIntent(); finish();startActivity(intent); Toast.makeText(getApplicationContext(), "refreshed", Toast.LENGTH_LONG).show(); } public void onBackPressed() { super.onBackPressed(); finish(); mHandler.removeCallbacks(null);

I'm very new to android programming so please forgive my noobie-ness. I'm trying to create a very simple activity that will have one TextView in the middle of the Layout and just have it switch to a different text every couple of seconds. For example, the TextView will say "text1", pause for a couple of seconds, then say "text2, and pause again. Eventually, I want to add more texts and have them all cycle one after another. I know this seems like a super simple thing but I'm mainly trying to learn about threads and handlers at this moment. Anyways, I've read up on how we should keep lengthy

I have an "open" animation and am using Handler.postDelayed(Runnable, delay) to trigger a "close" animation after a short delay. However, during the time between open and close, there is possibly another animation triggered by a click. My question is, how would I cancel the "close" animation in the handler? Just use the removeCallbacks(Runnable r) method. Daniel L. Cristian's answer is correct, but as opposed to what is stated in the answer's comments, you actually can remove callbacks for anonymous Runnables by calling removeCallbacksAndMessages(null); As stated here : Remove any pending

I am trying to use a nested postDelayed because I need to do something after (delayed for) 5 minutes, stop it after (delayed) 30 seconds, do something else, then repeat both events in the cycle again from the start. I just can't seem to get it right. code I have sofar: private long EnabledAfter = 300000; // 5 minutes private long DisabledAfter = 30000; // 30 seconds public void start_timers(){ on_delayed(EnabledAfter); }//end method private void on_delayed(long period_off){ Delayed = new Runnable() { public void run() { something.enable(context); something.enable_else(context, true); off
