Thanks for your message and efforts with my problem. I am really thankful
for that.
I've in this example neglect that onCreate() behave as you mentioned. I've
adjusted to code and shows like this just for testing:
public class DialogTestActivity extends Activity implements OnClickListener
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dialog_test);
((Button) findViewById(R.id.button1)).setOnClickListener(this);
}
@Override
public void onClick(View v) {
AskForNameDialog d = AskForNameDialog.newInstance(new
OnNameSetListener() {
@Override
public void onNameSet(AskForNameDialog dialog, String name) {
}
}, getString(R.string.enter_manufacturers_name));
d.show(getFragmentManager(), "dialog");
}
}
added a simple button (layout omitted here just linear with a button) and
this should open the dialog. It behaves exactly in the same manner as
already mentioned.
I have tried really all the stuff i found belonging to my problem, read the
android developer blog about this, and all this really not solve this.
Thank you for your help
Daniel
