Before and After:

Found couple resources in SO:

1. How to keep all fields and texts visible while the soft keyboard is shown
2. android soft keyboard spoils layout when appears
3. Adjust layout when soft keyboard is on

But the questions & answers are rather ambiguous, here's the question with clearer picture of what I want.

Requirements:

• It should work on phone with any screen sizes.
• Noticed that the margin/padding space at "FACEBOOK" and "Sign Up for Facebook" has changed before and after.
• No scroll view is involved.

Just add

android:windowSoftInputMode="adjustResize"

in your AndroidManifest.xml where you declare this particular activity and this will adjust the layout resize option.

some source code below for layout design
