I want to cause my program to pause for a certain number of milliseconds, how exactly would I do this?
I have found different ways such as Thread.sleep( time )
, but I don't think that is what I need. I just want to have my code pause at a certain line for x milliseconds. Any ideas would be greatly appreciated.
This is the original code in C...
extern void delay(UInt32 wait){
UInt32 ticks;
UInt32 pause;
ticks = TimGetTicks();
//use = ticks + (wait/4);
pause = ticks + (wait);
while(ticks < pause)
ticks = TimGetTicks();
}
wait is an amount of milliseconds
In between, we have also put the main thread to sleep by using TimeUnit. sleep() method. So the main thread can wait for some time and in the meantime, T1 will resume and complete its execution.
There may be many plugins in Android Studio that you are not using it. Disabling it will free up some space and reduce complex processes. To do so, Open Preferences >> Plugins and Disable the plugins you are not using.
In android Handler is mainly used to update the main thread from background thread or other than main thread. There are two methods are in handler. Post() − it going to post message from background thread to main thread using looper.
You really should not sleep the UI thread like this, you are likely to have your application force close with ActivityNotResponding exception if you do this.
If you want to delay some code from running for a certain amount of time use a Runnable and a Handler like this:
Runnable r = new Runnable() {
@Override
public void run(){
doSomething(); //<-- put your code in here.
}
};
Handler h = new Handler();
h.postDelayed(r, 1000); // <-- the "1000" is the delay time in miliseconds.
This way your code still gets delayed, but you are not "freezing" the UI thread which would result in poor performance at best, and ANR force close at worst.
You can use the Handler
class and the postDelayed()
method to do that:
Handler h =new Handler() ;
h.postDelayed(new Runnable() {
public void run() {
//put your code here
}
}, 2000);
}
2000 ms is the delayed time before execute the code inside the function
