Set initial background color before loading

Question

How can I set background color of an activity before setContentView. I have an activity which takes lot of time to load, I need to keep background white until activity finishes loading.

Try to add spinner in that activity and make the background transparent — Rakshit Nawani, May 14 '15 at 05:58
Make `rootView` Background White till your Loading and then make it different color after loading done — M D, May 14 '15 at 05:59
@MD I tried this `getWindow().getDecorView().findViewById(android.R.id.content).setBackgroundColor(0xffffffff);` but it's not working. — AVEbrahimi, May 14 '15 at 06:05

You can do one of the following:

setContentView can be called multiple times in activity lifecycle, So you can simply set another layout file which just shows the background as you require, and once you are done loading, call setContentView again to load the actual layout!

OR

You can simply manage all this in one layout file, by giving white background color to your root view than show/hide desired section as required!

In your oncreate add the following

Spinner = (ProgressBar) findViewById(R.id.LoginPageProgressBar);
    Spinner.setVisibility(View.GONE);

and when you click the button add the following before using intent

Spinner.setVisibility(View.VISIBLE);

From Documentation

setContentView(int layoutResID)

Set the activity content from a layout resource. The resource will be inflated, adding all top-level views to the activity.

So , it is not possible to give some background color before setContentView()

But try to

Avoid too much code in onCreate() of Activity .
Use AsyncTask to load Data & show a progressbar to the user
Or you can implement some splash screen before loading the main Activity.
