Question

Could you please tell me how to do a spinner that look like a list item that can be expanded?

I need something like shown in the figure given.! While clicking the arrow image the spinner pops up and the text is hide.

I use the following code.

spin.setOnItemSelectedListener(new OnItemSelectedListener() {  
        public void onItemSelected(AdapterView parent, View view, int position, long id) {  
            // hide selection text  
             ((TextView)view).setText(null);  
            // if you want you can change background here  
        }  
        public void onNothingSelected(AdapterView parent) {

        }  

      });

But then also there is flashing of text above the arrow background image for a second.

Any suggestion to avoid this?

try this

String[] androidBooks = 
    {
    "Hello, Android - Ed Burnette",
    "Professional Android 2 App Dev - Reto Meier",
    "Unlocking Android - Frank Ableson",
    "Android App Development - Blake Meike",
    "Pro Android 2 - Dave MacLean",
    "Beginning Android 2 - Mark Murphy",
    "Android Programming Tutorials - Mark Murphy",
    "Android Wireless App Development - Lauren Darcey",
    "Pro Android Games - Vladimir Silva",
    };



Spinner s=(Spinner)findViewById(R.id.Spinner01);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.select_dialog_singlechoice,androidBooks);
  s.setAdapter(adapter);
