How do I create an Android Spinner as a popup

Question

I want to bring up a spinner dialog when the user taps a menu item to allow the user to select an item   Do I need a separate dialog for this or can I use Spinner directly  I see this link  mentions a MODE DIALOG option but it doesn t seem to be defined anymore  AlertDialog may be OK but all the options say  clicking on an item in the list will not dismiss the dialog  which is what I want  Any suggestion   Ideally  the code would be similar to the case where the spinner is shown on the screen   ArrayAdapter lt String gt  adapter   new ArrayAdapter lt String gt  activity       android R layout simple spinner item  items                 adapter setDropDownViewResource android R layout simple spinner dropdown item   myspinner setAdapter adapter        myspinner showAsDialog    lt -- what i want

Here is an Spinner subclass which overrides performClick   to show a dialog instead of a dropdown  No XML required  Give it a try  let me know if it works for you  public class DialogSpinner extends Spinner       public DialogSpinner Context context            super context               Override      public boolean performClick             new AlertDialog Builder getContext    setAdapter  ListAdapter  getAdapter                 new DialogInterface OnClickListener                      Override public void onClick DialogInterface dialog  int which                        setSelection which                       dialog dismiss                                     create   show            return true           For more information read this article  How To Make Android Spinner Options Popup In A Dialog

You can use a spinner and set the spinnerMode to dialog  and set the layout width and layout height to 0  so that the main view does not show  only the dialog  dropdown view   Call performClick in the button click listener       mButtonAdd setOnClickListener view - gt            spinnerAddToList performClick              Layout        lt Spinner         android id    id spinnerAddToList          android layout width  0dp          android layout height  0dp          android layout marginTop  10dp          android prompt   string select from list          android theme   style ThemeOverlay AppCompat Light          android spinnerMode  dialog   gt    The advantage of this is you can customize your spinner any way you want    See my answer here to customize spinner  Overriding dropdown list style for Spinner in Dialog mode
