问题 I have a minor problem in one of my apps. It uses a BroadCastReceiver to detect when a call finishes and then performs some minor housekeeping tasks. These have to be delayed for a few seconds, to allow the user to see some data and to ensure that the call log has been updated. I'm currently using handler.postDelayed() for this purpose: public class CallEndReceiver extends BroadcastReceiver { @Override public void onReceive(final Context context, final Intent intent) { if (DebugFlags.LOG

问题 I am using handler.postDelayed method to create some delay for some animation stuff. Like this: Handler h = new Handler(); h.postDelayed(new Runnable() { @Override public void run() { // Start Animation. } }, 6000); Later, How can I get the remaining time until the animation starts? 回答1: You can simply save the time in a var when you call post delayed long startTime = System.nanoTime(); h.postDelayed(... and then when you need to check the remaining time you can calculate the elapsed time

问题 in my app I got a thrad that checks every 60s data from a webservice (defined in onCreate()): new Thread(new Runnable() { @Override public void run() { while (true) { try { Thread.sleep(PERIOD); if(condition) do_something(); } catch (Exception e) { e.printStackTrace(); } } } }).start(); Additionally i got a handler executing a method after a period of user inactivity: private Handler disconnectHandler = new Handler(); private Runnable disconnectCallback = new Runnable() { @Override public

问题 I have a problem with countdown timer.I try some of solutions and articles in this site but they never worked for me. so, please read my codes... also I used handler.postDelayed(new Runnable() { before and it was not my solution but it just worked correctly. Main question is: I want to do something like below: (button pressed) do some codes1 delay1 do other codes2 delay2 go back to *do some codes1* again. In short, this is my real code: itimesec--; setdelay(); irepeat--; setrelax(); and this
