Question

I need to pass the root view to a function in order to show a popup window

instructions_popup_window.showAtLocation( "parent view", Gravity.CENTER, 0, 0);

the problem is what to put as "parent view".

In the onCreate I have

setContentView(R.layout.splash);

So is my root view: "R.layout.splash" or "findViewById(R.layout.splash)" or something else altogether?

The root view is the topmost view in your splash layout.

You can give it an ID and then findviewbyid it OR you can get the activity’s root view with this function:

getWindow().getDecorView()
