public class Main extends Activity implements OnClickListener{

TextView textview_countries;

private String[] countries_list={"Philippines","Japan","Australia"};
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    textview_countries=(TextView) findViewById(R.id.txtview_countries);
    textview_countries.setInputType(InputType.TYPE_NULL); //To hide the softkeyboard


    final ArrayAdapter<String> spinner_countries = new  ArrayAdapter<String>(Main.this,android.R.layout.simple_spinner_dropdown_item, countries_list);

    textview_countries.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            new AlertDialog.Builder(Main.this)
                  .setTitle("Select Countries")
                  .setAdapter(spinner_countries, new DialogInterface.OnClickListener() {

                    public void onClick(DialogInterface dialog, int which) {
                        textview_countries.setText(countries_list[which].toString());
                      dialog.dismiss();
                    }
                  }).create().show();
        }
    });
 }
