问题
I have an issue with a simple layout. If I set
android:windowSoftInputMode="stateHidden|adjustResize"
this happens: Bug
In any case this happens only If I open keyboard from landscape, then rotate (with keyboard open). In normal use (rotating and then opening keyboard) this does not happens!
If I set
android:windowSoftInputMode="stateHidden|adjustPan"
ActionBar is pushed up.
Here layout code:

FIX: The problem was in mikepenz MaterialDrawer. Now I contacted mike and we fixed the bug
回答1:
The problem occurs when the SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN flag, which is required to display the drawer behind the StatusBar.
As a solution for this I implemented the KeyboardUtil which adds the height of the keyboard as padding to the contentview. As there is no listener to get an event when the keyboard is shown, this is done via a OnGlobalLayoutListener.
@MarcoCount had a special usecase which caused the KeyboardUtil to not working correctly. With the help of him we came to an updated version of the KeyboardUtil which now also works when the screen is rotated, and the Keyboard keeps showing the whole time.
Here's the source of the updated KeyboardUtil in case someone needs it. It is also available on GitHub within the source of the MaterialDrawer

回答2:
try to use scroll view in your layout instead of adding adjustpan at manifest file. Using the scroll view your screen is adjustable and scrollable and this will not scroll up your toolbar or action bar and not gonna to hide your layout.
<ScrollView>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars = "vertical"
android:scrollbarStyle="insideInset"
> </ScrollView>
try using this layout as your parent layout. But scroll view cant be used as the base layout for that you have to use the scrollView inside a linear or relative layout.
