To display different dialogs, you have couple options. 1. Continue to use dialogs managed by the activity, but pass different ids in showDialog(int), and in your onCreateDialog(int id), check the parameter id and return the appropriate dialog. In your current code, you're passing 0 in both bt1 and but2. Pass different ids. Also in your onCreateDialog, you're dismissing the dialog immediately, which doesn't make sense. You should be returning the dialog instance you just created.
2. Create a new dialog every time an event happens. In your case, create() and show() a new dialog instance in bt1 or bt2 onClickListener () event.
