how to make scene adjusted to soft keyboard?

When I focus on a EditBox, the popped soft keyboard would hide some part of the scene.
I don’t like it. I want the keyboard push up the scene.I’ve tried to add:

<activity android:windowSoftInputMode=“stateVisible|adjustResize” . . . >

into manifest.xml. But it doesn’t work…What should I do to solve this problem? thank you~
