Use of spinner in Android

This blog post describes how to use the basic spinner

First write the Code section in XML

<spinner android:id= "@+id/myspinner" android:layout_width= "fill_parent" android:layout_height= "Wrap_content" />

Write the file section in Strings.xml again.

<string-array name= "Tongxue" > <item> hou </item> <item> Zhang </ite M> <item> Zhao </item> <item> Lee </item> <item> Lee </item> <ite M> Liu </item> </string-array>

Finally, let's show you the Code section of the activity.

public class mainactivity extends activity {private spinner spin;      @Override     protected void oncreate (bundle  savedinstancestate)  {        super.oncreate (savedInstanceState);         setcontentview (R.layout.activity_main);         spin= (Spinner) Findviewbyid (R.id.myspinner);         arrayadapter<charsequence> adapter=arrayadapter.createfromresource (this,  R.array.tongxue, android. R.layout.simple_spinner_item);         adapter.setdropdownviewresource ( Android. R.layout.simple_spinner_dropdown_item);         spin.setadapter (Adapter );         spin.setprompt ("Test");         spin.setonitemselectedlistener (New spinnerlis ());             }    //Define a listener     class SpinnerLis  implements onitemselectedlistener{@Overridepublic  void onitemselected (adapterview<?>  parent, view view,int position, long id)  {string selected= Parent.getitematposition (position). ToString (); Toast.maketext (Getapplicationcontext (),  selected, toast.length_long). Show (); @Overridepublic  void onnothingselected (adapterview<?> parent)  {}         }
