I have a really long onActivityCreated for one of my fragments because it has to initialize a big gridlayout. Instead of using xml, I did it programmatically because it is easier on my life to code than to create 108 separate views using xml. The only problem: it takes forever to load everything when the fragment is created.
I have tried to use AsyncTaskLoader and that didn't work because you can't change a view using a different thread. Please tell me anyway I can make it run faster or better. This is my first app, so there is a good chance I am just being really dumb. Any help is appreciated.
Also I am doing many things in this fragment, like using mediaplayers and using onclicklisteners. All that works perfectly, its just really slow to make the fragment load. This is my code:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
if (savedInstanceState == null) {
TextViewCompat.setAutoSizeTextTypeWithDefaults(textTranslation, TextViewCompat.AUTO_SIZE_TEXT_TYPE_UNIFORM);
GridLayout gridLayout = v.findViewById(R.id.grid_layout);
final MediaPlayer[] sound_resource = {MediaPlayer.create(v.getContext(), R.raw.a_sound),
MediaPlayer.create(v.getContext(), R.raw.b_sound), MediaPlayer.create(v.getContext(), R.raw.c_sound),
