/** Called when the activity is first created. */
Dialog dialog;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
dialog = new Dialog(this);
dialog.setContentView(R.layout.main2);
dialog.setTitle("This is my custom dialog box");
dialog.setCancelable(true);
Button b=(Button)findViewById(R.id.button1);

b.setOnClickListener(new OnClickListener() {
  public void onBackPressed() {
    Intent intent = new Intent(DlogActivity.this, DlogActivity.class);
    startActivity(intent);
    finish();
  }

  public void onClick(View v) {

Your code is totally confusing to me. I suspect that you might be confused about the difference between an activity and a dialog. If all you are trying to do is show a dialog on top of your activity, and then return to that activity when the dialog is dismissed, you need dialog.dismiss(). Read this

If you are trying to achieve something else, please explain.
