#ANDROID STUDIO HANDLER ANDROID#
If you want to communicate with the UI thread, then use one of the recommended methods of doing that. Developing Android Apps Using Android Studio 2022.2.1 and Kotlin Neil Smyth. But I suspect you don't really want to create a handler. So if you really want to use a handler in your worker thread (as distinct from the User Interface thread on which the rest of your app runs) you have to become very familiar with loopers and how they are used. Set time to handler and call Handler().postDelayed, it will call run method of runnable after set time and redirect to main app screen. But basically the thread just runs straight line code, being interrupted only by Android OS time sharing and by calling blocking system methods (functions that must wait for something to happen before they can return.) It is never a good idea to have a thread sit "spinning its wheels" so to speak. This is how you can create your own CustomHandler like android handler by using only Java. Switch to your activity behavior class and add below method.
Switch to the Text tab of your layout, press ALT + ENTER on the warning on 'onClick' attribute, and then choose Create onClick Handler, choose the activity and hit OK. There are special mechanisms provided by Android to allow a worker thread to signal to the UI how it is going and when it is done. First: you can type anything in onClick attribute and press Enter then will place below in your layout.
#ANDROID STUDIO HANDLER CODE#
The UI code is built upon the idea that it is supposed to respond to events and then quickly return to the system (which is a looper).Ī worker thread, on the other hand, is generally something that you start up to do something on its own without any interaction with the user. Someone have recommend me Handler another recommend me AlarmManager but I don't know which method fits better with NSTimer.
In iOS, I have NSTimer, but in Android I don't know what to use. These events can be anything from button presses to timers expiring. 161 I'm developing an Android 2.3.3 application and I need to run a method every X seconds. A looper is like a dispatcher that dispatches events to handlers in your code. Almost everybody who uses handlers uses them in the UI thread because the UI thread runs under a looper.
The first thing you should do is re-evaluate why you are trying to use a handler in a thread other than the UI thread (which as a system-supplied looper).
