you might want style spinner like:

one approach: (that won't work)

<style name="dropdown" parent="android:style/widget.holo.light.spinner.dropdown.actionbar">     <item name="android:typeface">"mytypeface"</item>  <--- there no way reference custom typeface </style> 

second approach:

package com.example.spinner;  import android.app.alertdialog; import android.content.context; import android.content.dialoginterface; import android.graphics.typeface; import android.util.attributeset; import android.view.hapticfeedbackconstants; import android.view.view; import android.view.accessibility.accessibilityevent; import android.widget.listadapter; import android.widget.spinner; import android.widget.textview;  public class spinnerplus extends spinner implements dialoginterface.onclicklistener{       private listadapter mpromptadapter;     private alertdialog mpromptdialog;     private onlongclicklistener monlongclicklistener;     public spinnerplus(context context, attributeset attrs, int defstyle,             int mode) {         super(context, attrs, defstyle, mode);         // todo auto-generated constructor stub     }      public spinnerplus(context context, attributeset attrs, int defstyle) {         super(context, attrs, defstyle);         // todo auto-generated constructor stub     }      public spinnerplus(context context, attributeset attrs) {         super(context, attrs);         // todo auto-generated constructor stub     }        public spinnerplus(context context, int mode) {         super(context, mode);         // todo auto-generated constructor stub     }      public spinnerplus(context context) {         super(context);         // todo auto-generated constructor stub     }      public void setpromptadapter(listadapter adapter){         mpromptadapter = adapter;     }     @override     public void setprompt(charsequence prompt) {         alertdialog.builder builder = new alertdialog.builder(getcontext());         textview titleview = new textview(getcontext());         settypeface(titleview);         builder.setcustomtitle(titleview);         builder.setsinglechoiceitems(mpromptadapter, getselecteditemposition(), this);         mpromptdialog = builder.create();      }     @override     public void onclick(dialoginterface dialog, int which) {         // todo auto-generated method stub         super.setselection(which);         mpromptdialog.dismiss();         mpromptdialog = null;      }      @override     public boolean performclick() {         if(!performclick1()){             mpromptdialog.show();             return true;         }         return false;     }     @override     public void setonitemclicklistener(onitemclicklistener l) {         super.setonitemclicklistener(l);     }      @override     public void setonlongclicklistener(onlongclicklistener l) {         monlongclicklistener = l;         super.setonlongclicklistener(l);     }      private void settypeface(textview t){          typeface tf = typeface.createfromasset(t.getcontext().getassets(), "fonts/exo-bold.otf");          t.settypeface(tf);     }    private boolean performclick1(){               sendaccessibilityevent(accessibilityevent.type_view_long_clicked);                 boolean handled = false;                if (monlongclicklistener != null) {                    handled = monlongclicklistener.onlongclick(this);                  }                if (!handled) {                    handled = showcontextmenu();                }                if (handled) {                   performhapticfeedback(hapticfeedbackconstants.long_press);                }                return handled;    }  } 

specify needed font in prompt adapter :)

cheers,
