import android.widget.Button;

public class AndroidAlertDialog extends Activity {

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
      
       Button buttonStartDialog = (Button)findViewById(R.id.startdialog);
       buttonStartDialog.setOnClickListener(new Button.OnClickListener(){

  @Override
  public void onClick(View arg0) {
   // TODO Auto-generated method stub
  
   //Create AlertDialog here
   AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(AndroidAlertDialog.this);
      myAlertDialog.setTitle("--- Title ---");
      myAlertDialog.setMessage("Alert Dialog Message");
      myAlertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
       
             // do something when the button is clicked
             public void onClick(DialogInterface arg0, int arg1) {
                 //...
             }
