How to call a method after a delay in Android

Question

I want to be able to call the following method after a specified delay. In objective c there was something like:

[self performSelector:@selector(DoSomething) withObject:nil afterDelay:5];

Is there an equivalent of this method in android with java? For example I need to be able to call a method after 5 seconds.

public void DoSomething()
{
     //do something here
}

Answer 1

Kotlin

Handler(Looper.getMainLooper()).postDelayed({
    //Do something after 100ms
}, 100)

Java

final Handler handler = new Handler(Looper.getMainLooper());
handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        //Do something after 100ms
    }
}, 100);

The class to import is android.os.handler.
