我有一個對話框片段，我需要在此對話框片段中啓動一個片段。這意味着我的片段應該佔用與對話框片段相同的窗口。我該怎麼做呢？這是我的對話框片段代碼 -Android在對話框片段中啓動片段
public class CallDialogFragment extends DialogFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.call_dialog_fragment, container, false);
return view;
}
}
只需使用片段事務並添加另一個對話框片段即可。並添加回棧。
你可以使用協調員佈局的對話框片段..當你把佈局拖到上面時，它將成爲你的新片段。當你拖下來它將是你的對話框片段。
這裏是XML代碼..
