Question

I’d like to make a welcome screen just for 1 time. It should not be a splash screen because I’d put a TextEdit and a button to get the user’s username. I need to see some examples of the code that would do it, thanks for stopping by! 😀

Answer 1

1. First let the user insert his Username in the TextView.

2. When the user press the Button, then do the following…

– Use Intent to move to the next Activity you want to divert him after this Staring Activiy.

Eg:

    Intent i = new Intent(StartActivity.this, DesiredActivity.class);

– Now after you use startActivity() method with Intent as the argument, do use finish() method, that will remove this StartActivity from the Back-Stack.

Eg:

    Intent i = new Intent(StartActivity.this, DesiredActivity.class);
    startActivity(i);
    finish();

Now if the user press back button from the DesiredActivity( the one you went from StartActivity), the app will exit.

You don’t want you app not to go to the First activity again, where you have already given the username.. After the first time..right ??????

– Then to do this… i will recommend you to do the below….

i. First save the username that user inputs the first time into Shared Preference or into a file, or a Database.

ii. Now when you open you app, let there be a thread which checks the existence of the username in the Shared Preference or in a file, or a Database, resp wherever u have saved it.

iii. If found let it move to the desired activity, if not prompt him to input the username, thats what happen the 1st time you open your app.

iv. Now its also about user-friendliness, so i recommend you to use a splash activity in the beginning, and fire your checking thread from here. So the user wont feel awkward looking at the blank screen while the thread checks the username
