Screen occluded by keyboard

Hi, (searched for other users' solutions, but found nothing so far)...

My textbox is near the bottom of my app screen. Click on it and the screen-keyboard obviously occludes the screen and the textbox I want to edit.
How do I get my app's screen to slideUpwards so that the keyboard is accommodated and the selected textbox remains visible?
Thanks for all ideas on this.
