Question

我试图在对话框（弹出窗口）中添加两个微调器。我遇到的问题是填充纺纱厂。我没有看到任何错误，如果它位于制表符片段而不是对话框中，基本相同的代码可以正常工作。

这是不会在对话框中弹出微调器的代码。

public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();

    League league;

    league = ((LeagueMainActivity)getActivity()).getLeague();

    View v = inflater.inflate(R.layout.diaglog_add_match, null);

    Spinner spinner1 = (Spinner) v.findViewById(R.id.spinner_dialog_player1);
    Spinner spinner2 = (Spinner) v.findViewById(R.id.spinner_dialog_player2);

    String [] items = {"test 1", "test 2"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
            android.R.layout.simple_spinner_item, items);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    Log.d("Spinner: ", "" + spinner1);

    spinner1.setAdapter(adapter);
    spinner2.setAdapter(adapter);

    builder.setView(inflater.inflate(R.layout.diaglog_add_match, null))
            .setTitle("Add match")
            .setPositiveButton("Create", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    // sign in the user ...
                }
            })
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    //LoginDialogFragment.this.getDialog().cancel();
                    /* do I really need to do anything??? */
                }
            });

    AlertDialog dialog = builder.create();
    return dialog;
}

这是在（选项卡式）片段中工作的代码：

public class UnnamedFragment extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_unnamed, container, false);

    Spinner spinner1 = (Spinner) rootView.findViewById(R.id.spinner);

    String [] items = {"test 1", "test 2"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
            android.R.layout.simple_spinner_item, items);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    Log.d("Spinner: ", "" + spinner1);

    spinner1.setAdapter(adapter);

    return rootView;
}

}

好的，我做错了是用相同的上下文来膨胀/创建两个独立的视图。

首先我做了：

 View v = inflater.inflate(R.layout.diaglog_add_match, null);

然后：

builder.setView(inflater.inflate(R.layout.diaglog_add_match, null))

所以我将构建器的视图设置为新视图，而不是我用于微调器的视图。所以，如果我这样做：

View v = inflater.inflate(R.layout.diaglog_add_match, null);
builder.setView(v)

这就是诀窍。

Android - 对话框中的微调器不会填充
