Layout dancing when user tap on QTextEdit in Android

When layout contains QTextEdit and some controls under it, tapping makes layout dance. See image for details.

After step 3 behaviour repeated: Tap -> layout atop virtual keyboard: Tap -> layout under virtual keyboard...

I make red scrollbars for better understanding.

UPD 1: Using android:windowSoftInputMode="adjustResize" not fix it.
UPD 2: Sometimes after application start and clicking to qtextedit it not adjust layout, but if I change device orientation and go back, it again works line on screenshots.
