问题
AutoCompleteTextView displays it's suggestions in a dropdown in the portrait mode.I would like to display suggestions either in a dialog or in a dropdown in the landscape mode,here the EditText and the keyboard go full screen.
Which layout should I use in the Adapter to display hints as a dialog in landscape mode.
Im currently using android.R.layout.simple_dropdown_item_1line.
回答1:
In the layout where you defined your AutoCompleteTextView use android:imeOptions=flagNoExtractUi
The flag prevents the element from going full-screen when it is rotated to landscape mode.

@vamsiampolu answer is correct but if you want to use same by using java, you can use
itemautoTxt.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI);
where itemautoTxt is AutoCompleteTextView
hope this will helpful to others.

Firstly, set this android:imeOptions="flagNoExtractUi" in XML.
Secondly, your dropdown may be under your keybord or above it. So it may not fit on screen - appear below or above the visible area of the screen. To fix this use android:dropDownAnchor="@id/your_view" to pin dropdown to the required view.
Thirdly, the dropdown may not appear on some devices or may appear unstable.
