                 t[1].setVisibility(View.VISIBLE);
                 t[2].setVisibility(View.VISIBLE);

"It's not working" is one of the most useless problem descriptions we get: it tells us absolutely nothing about the problem. We don't know if you get an error message, or the wrong data, or even that that code compiles successfully!
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
So tell us what happens when you run that code, what you expected to happen, how you checked what happened. Help us to help you!

Java

EditText[] t;
t[0].setVisibility(View.VISIBLE);
t[1].setVisibility(View.VISIBLE);

You have created the array t, but it does not contain anything. So t[0], t[1] etc. do not exist. You must add references to actual EditText items in each entry that you are trying to use. Something like:

Java

EditText[] t = new EditText[6];
t[0] = new EditText;
t[0].setVisibility(View.VISIBLE);

You are welcome. Creating a loop should be quite simple.
