我想有我的自定义弹出窗口显示在一个片段。 不幸的是，对象对话框没有引用正确的布局。 我怎样才能让它指向正确的布局？ 我希望有人能向我解释一下错误在哪里，这样我就可以调出来了。
public class UserFragmentBestell<Textview> extends Fragment {
RecyclerView recyclerView;
TextView notfound;
Dialog epicDialog;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.user_fragment_bestell, container, false);
recyclerView = view.findViewById(R.id.recyclerview_scroll);
notfound = view.findViewById(R.id.user_order_notfound);
getBestellungen();
epicDialog = new Dialog(getActivity());
return view;
}
public void callAction(int pId) {
System.out.println(pId);
epicDialog.setContentView(R.layout.user_popup_order_overview);
epicDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
Button btn_order_overview_finish = (Button) epicDialog.findViewById(R.id.btn_order_overview_finish);
//System.out.println(bestellung.get(position).getBestellnummer());
btn_order_overview_finish.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
epicDialog.dismiss();
}
});
epicDialog.show();
}
}
文档建议您不应直接实例化对话框，而是使用AlterDialog
public void callAction(int pId){ // idk what you're doing with pid
new AlertDialog.Builder(getActivity())
.setMessage("message") //set the message on the dialog
.setView(R.layout.user_popup_order_overview) // set layout as view of this dialog
.setNegativeButton("cancel",null) // pressing cancel will dismiss this dialog
}).create().show() // create and show this dialog;
}
祝你今天愉快
