It a default layout when you change your device orientation to landscape.

Add

android:imeOptions="flagNoExtractUi|flagNoFullscreen"

to disable the fullscreen editing view

<EditText
    android:id="@+id/edit_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:imeOptions="flagNoExtractUi|flagNoFullscreen"
    android:hint="annotation text"
    android:inputType="text"
    android:textSize="14sp"/>

flagNoExtractUi Used to specify that the IME does not need to show its extracted text UI. For input methods that may be fullscreen, often when in landscape mode, this allows them to be smaller and let part of the application be shown behind. Though there will likely be limited access to the application available from the user, it can make the experience of a (mostly) fullscreen IME less jarring. Note that when this flag is specified the IME may not be set up to be able to display text, so it should only be used in situations where this is not needed.

flagNoFullscreen Used to request that the IME never go into fullscreen mode. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it.
