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

You can create your own custom Dialog  It s fairly easy  If you want to dismiss it with a selection in the spinner  then add an OnItemClickListener and add  int n   mSpinner getSelectedItemPosition    mReadyListener ready n   SpinnerDialog this dismiss      as in the OnClickListener for the OK button  There s one caveat  though  and it s that the onclick listener does not fire if you reselect the default option  You need the OK button also   Start with the layout   res layout spinner dialog xml    lt  xml version  1 0  encoding  utf-8   gt   lt RelativeLayout xmlns android  http   schemas android com apk res android    android layout width  wrap content     android layout height  wrap content  gt   lt TextView      android id    id dialog label       android layout height  wrap content       android layout width  fill parent      android hint  Please select an option         gt   lt Spinner     android id    id dialog spinner       android layout height  wrap content       android layout width  fill parent        gt   lt Button     android id    id dialogOK       android layout width  120dp      android layout height  wrap content       android text  OK      android layout below   id dialog spinner        gt   lt Button     android id    id dialogCancel       android layout width  120dp      android layout height  wrap content       android text  Cancel      android layout below   id dialog spinner      android layout toRightOf   id dialogOK        gt   lt  RelativeLayout gt    Then  create the class   src your package SpinnerDialog java   public class SpinnerDialog extends Dialog       private ArrayList lt String gt  mList      private Context mContext      private Spinner mSpinner      public interface DialogListener           public void ready int n           public void cancelled               private DialogListener mReadyListener       public SpinnerDialog Context context  ArrayList lt String gt  list  DialogListener readyListener            super context           mReadyListener   readyListener          mContext   context          mList   new ArrayList lt String gt             mList   list              Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState            setContentView R layout spinner dialog           mSpinner    Spinner  findViewById  R id dialog spinner           ArrayAdapter lt String gt  adapter   new ArrayAdapter lt String gt   mContext  android R layout simple spinner dropdown item  mList           mSpinner setAdapter adapter            Button buttonOK    Button  findViewById R id dialogOK           Button buttonCancel    Button  findViewById R id dialogCancel           buttonOK setOnClickListener new android view View OnClickListener                public void onClick View v                    int n   mSpinner getSelectedItemPosition                    mReadyListener ready n                   SpinnerDialog this dismiss                                      buttonCancel setOnClickListener new android view View OnClickListener                public void onClick View v                    mReadyListener cancelled                    SpinnerDialog this dismiss                                        Finally  use it as   mSpinnerDialog   new SpinnerDialog this  mTimers  new SpinnerDialog DialogListener       public void cancelled            do your code here       public void ready int n           do your code here

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

Here is a Kotlin version based on the accepted answer   I m using this dialog from an adapter  every time a button is clicked   yourButton setOnClickListener       showDialog it   here I pass additional arguments        In order to prevent double clicks I immediately disable the button  and re-enable after the action is executed   cancelled   private fun showDialog view  View   additional parameters          view isEnabled   false      val builder   AlertDialog Builder context      builder setTitle R string your dialog title       val options   arrayOf  Option A    Option B        builder setItems options    dialog  which - gt          dialog dismiss            when  which                   execute here your actions                0 - gt  context toast  Selected option A               1 - gt  context toast  Selected option B                      view isEnabled   true            builder setOnCancelListener           view isEnabled   true            builder show       You can use this instead of a context variable if you are using it from an Activity

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
