[android-developers] spliting srings
Hello sorry for the simple and i guess basic question but how would i get some lines ot text saved in a .txt file on a sd card. then split the line and display word 1 and word 3. the words are separated by commas. i have spent a good few hours looking through google for the answer but have not come up with any code that works. i can read a file and display it and i can split a string but i cant seem to merge these two parts and get it to work regards -- You received this message because you are subscribed to the Google Groups Android Developers group.

figure it out.

In this snippet, you're not re-initializing datetime to the current
time, so it's going to keep the same value you assigned to it earlier
(in onCreate?), no matter how many times you click the button.
Oh, and rather than getBaseContext(), use your activity
class.class or v.getContext().
