Disabling the fullscreen editing view for soft keyboard input in landscape?

I finally answered my own question:

The extract UI (i.e. the fullscreen editing mode) can be disabled at the point at which the input connection is hooked up:

@Overridepublic InputConnection onCreateInputConnection(EditorInfo outAttrs) {    outAttrs.imeOptions = EditorInfo.IME_FLAG_NO_EXTRACT_UI;    // etc.}

To do that, navigate to activity xml and paste android:imeOptions="flagNoExtractUi" in your code. But where should it be pasted? Have look at code of example activity xml and look at EditText:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"             >    <EditText        android:imeOptions="flagNoExtractUi"        android:id="@+id/etTextInAct"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:ems="10" >           <requestFocus />    </EditText></LinearLayout>      

If you want more customisation options for the keyboard see http://developer.android.com/guide/topics/ui/controls/text.html

add the property android:imeOptions="flagNoExtractUi" to each EditText in your XML file.
