hi everyone-- got questions about android..... the MAIN.XML screen has the following items in this order: 1. TextView01 2. EditText (called gF) 3. EditText (called fF) 4. EditText (called sF) 5. EditText (called ttlF) 6. EditText (called nF) and at the bottom of the screen, a botton called cB(that performs the calculations).
i need to be able to READ and check if the user has entered a valid input into the first field(gF). such as a double value/float value within a given range( greater than 1.01 and less than 99.98). this should not be an integer. if that number is not within that range, change the TextView01(string) informing the user what that range should be(i.e "Please enter a value between 1.00 and 99.99"). pause xx seconds, and restore the original text to TextView01. if gF is within the allowed range, button cB would/should be ENABLED, the user presses it, the fields(EditText(3 thru 6) would be calculated and filled in with whatever those values come out to be. i have not been able to figure out how to READ what the user entered into field(gF), how to PLACE/ASSIGN those values to fields 3-6(once the calculations are done), how to get the calculation portion to fire up, validate a range, OR change a TextView01(string). i am at a COMPLETE loss. can/would anyone be able to help me? thank all of you for your kind attention. rc3375. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
