alertDialog中的Listview，将listview定位在我想要的地方就是我卡住的地方

Question

我有一个由多个片段或活动读取的警报对话框，在一个实例中，警报对话框将显示一个带有 2 个 editText 选项以及标准正负按钮按下的 listView，我想将 listView 定位在 editTexts 之后我被困住了。

一切都正常显示，但定位是我卡住的地方。

对话框类

public class addTaskDialog extends DialogFragment {

String mString;
taskDialogListener listener;
ArrayList<String> tradeTitles;

/*
 * Class interface from jobRoomDetails, interfaces are called from the parent activity class
 */
public interface taskDialogListener {
    void onDialogPositiveClick(DialogFragment dialog);
    void onDialogNegativeClick(DialogFragment dialog);
    void onDialogListSelect();
}

@Override
public void onAttach(@NonNull Context context) {
    super.onAttach(context);
    try{
        listener = (taskDialogListener) context;
    } catch(ClassCastException e) {
        throw new ClassCastException(getActivity().toString() + "must implement taskDialogListener");
    }
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    AlertDialog alert = builder.create();
    mString = getArguments().getString("title");
    tradeTitles = getArguments().getStringArrayList("tradeTitleArray");
    builder.setTitle(mString);


    //Inflate the layout dialog_add_task.xml
    LayoutInflater inflater = requireActivity().getLayoutInflater();

    //Pattern matcher for literal strings from different addTaskDialog calls
    Pattern p = Pattern.compile("Add new task +");
    Matcher m = p.matcher(mString);
    Pattern q = Pattern.compile("Add Task +");
    Matcher n = q.matcher(mString);

    /*
     *Test for new task and add trade names, this means that the calling window is jobRoomDetails and this is a new task
     * and it will be assigned to a trade upon creation
     */
    if(m.find()){
        Log.d("Line: 56","Test for trade name" + tradeTitles.toString());
        final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(getContext(), android.R.layout.select_dialog_singlechoice, tradeTitles);
        //ListView list = (ListView) alert.findViewById(R.id.tradeItems);
        builder.setView(inflater.inflate(R.layout.dialog_add_task, null))
                .setPositiveButton(R.string.confirm, new DialogInterface.OnClickListener() {

                        //Save the new task to task hashmap
                        listener.onDialogPositiveClick(addTaskDialog.this);
                    }
                })

                        listener.onDialogNegativeClick(addTaskDialog.this);
                    }
                })

            public void onClick(DialogInterface dialogInterface, int i) {

    } else if (n.find()){

                .setPositiveButton(R.string.confirm, new DialogInterface.OnClickListener() {

                        //Save the new task to task hashmap
                        listener.onDialogPositiveClick(addTaskDialog.this);
                    }
                })
                .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {

                    }
                });

    } else {

有一次我尝试通过 listView 添加它但没有成功，我认为 onCreateDialog 上的返回类型可能会阻碍事情，但我不确定，我认为返回类型是必要的，因为我带来通过争论，但我可能是错的。一如既往地感谢您的帮助。

简单的答案是创建您自己的警报对话框，您可以简单地制作一个看起来和行为类似于警报对话框但功能更多的片段。
