Android call Method after rendering a Layout

I started programming Android apps. But I have one question. Is it possible to call a method first after the Layout belonging to the Activity has renderd and not at the onCreate() method?

Look at the activity lifecycle (scroll down a bit for it) to see the hooks that you have. The layout is usually rendered (as in measured, laid-out, etc) when you call setContentView inside onCreate, but becomes visible on-screen only after onResume. Note that onResume can be called multiple times, while onCreate is only called once.

setContentView

onCreate

onResume

onResume

onCreate

no it is not possible to call a method first after the Layout belonging to the Activity has renderd. oncreate is start point of your activity. check following link for more information

Use onStart():

onStart()

@Override
protected void onStart() {
super.onStart();
// WRITE YOUR CODES HERE
}


You can write after rendering works inside the onStart()

onStart()
