okay thanks Dianne. You have been great help! One more question(sorry to keep troubling you): Is there any way to have my OWN softkeyboard just for one application.
Eg: I have an EditText. I want a custom softkeyboard to show only when I edit this text box only in my app. I dont want it to be used for any other apps. OR is there is way to disable the popping up of the system IME when I click an EditText?
