how to create an Alert Dialogu in Android without onCliclkListener

I wanted to display an Alert Dialogue inside thread or alternatively such a way that AlertDialogue opens up directly after finding some records in database negative, w/o clicking on any button.. Alert dialogue may contain Few 开发者_开发百科lines and 2-3 buttons..

referred following link and tried on my own but not getting how to create an AlertDialogue without using onClickListener as its working with it(onClickListener) very smoothly:

Thanks in Advance.

public class jar_layut extends Activity {
    /** Called when the activity is first created. */
    boolean out=false;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        new Thread(new Runnable() 
        { public void run() 
        { 
            try {
                out=first_check_pic_on_device();

                mHandlerMySpace5.post(mUpdateResultsMySpace5);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                mHandlerMySpace5.post(mUpdateResultsMySpace5);
            }

        }
      } ).start();
    }
    private boolean first_check_pic_on_device()
    {
         Context contextMySpace= this;;

        try {
            FileInputStream stream =contextMySpace.openFileInput("prf.png");

                  try {



                      return true;

                  } catch (Exception e) {
                        // TODO Auto-generated catch block

                      return false;
                    }
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            return false;
        }
    }
    final Handler mHandlerMySpace5 = new Handler();

    final Runnable mUpdateResultsMySpace5 = new Runnable() {
        public void run() {
            if(!out)
            {
                showDialog();
            }

        }
    };
    private void showDialog()
    {

         final CharSequence[] items = {"one", "two"};
        AlertDialog.Builder builder = new AlertDialog.Builder(this);

            builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int item) {

                    if(item==0)
                    {


                    }
                    if(item==1)
                    {

                    }
                }
            });
            AlertDialog alert = builder.create();
            alert.show();

    }
}
