Flash Card Tutor

This Android application is intended to work like "flash cards" that have an quiz question on one side and the answer on the flip side. It has 2 displays boxes: An upper box in which a "quiz" line is displayed, and a lower box in which an Answer is displayed. In its simplest form, the user touches the upper box to see the next randomly chosen Quiz line. If he doesn't know the answer, he can touch the lower box to see the Answer.

The Quiz and Answer lines are derived from a file. The file is organized with Quiz lines on an even numbered line, and the Answer lines on odd-numbered lines, as shown in this example for Thai language training:

Hello [-- on line #0 --)
Saw wat dee kup [-- one line #1--]
Excuse me [-- on line #2 --]
Kho thoet kup [-- on line #3 --]
I speak Thai a little [-- on line #4 --]
Phom phut paasaa Thai dai nitnoi kup [-- on line #5 --]
(Another even-numbered quiz line)
(Another odd-numbered answer line, etc.)
