Hi.
Need help here.
I have 2 input text where user must enter their phone number. Then if the phone number is match, it will go to other page, if not the user must re-enter the phone number. The problem is, how to compare the value that entered by the user and verify whether it is match or not?

@ainie89
you can achieve this by using this simple logic.

if( ! textField2.getText().toString().matches(textField1))
{
// do this..
}

hope it helps.
