layout of the screen moves up when keyboard is displayed

Try using

android:windowSoftInputMode="adjustPan|adjustResize"

for the activity.

well, I have not mentioned any "windowSoftInputMode" in my app's manifest and it runs fine. Screen does not move up when the keyboard opens up. Try this approach - just remove the "windowSoftInputMode" parameter from your manifest .

Try this:

android:windowSoftInputMode="adjustNothing"
