ArrayAdapter要求资源ID为DialogFragment中的TextView [英] ArrayAdapter requires the resource ID to be a TextView in DialogFragment

问题描述

我在DialogFragment中使用了ArrayAdapter，它可以在Android 4.0及更高版本上运行，但不能在2.3中运行.

I use an ArrayAdapter in a DialogFragment, that work on Android 4.0 and more but not in 2.3.

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Get the layout inflater
    LayoutInflater inflater = getActivity().getLayoutInflater();

    View view = inflater.inflate(R.layout.dialog, null);

    Spinner spReglement;
    spReglement = (Spinner)view.findViewById(R.id.listReglements);

    ArrayAdapter<String> adapterList = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1);
    adapterList.setDropDownViewResource(R.layout.customspinner);
    spReglement.setAdapter(adapterList);

    HashMap<Integer, String> mapReglement = new HashMap<Integer, String>();
    mapReglement.put(-1, "");
    adapterList.add("");
    for(int i=0; i<alReglement.size();i++){
        String libelle = String.valueOf(alReglement.get(i).get("Libelle"));         
        mapReglement.put(i, libelle);
        adapterList.add(libelle);           
    }
    builder.setView(view)
           .setPositiveButton("Valider", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   mListener.onDialogPositiveClick(DialogFSE.this);
               }
           })
           .setNegativeButton("Annuler", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   mListener.onDialogNegativeClick(DialogFSE.this);
               }
           });      
    return builder.create();

}

我的布局对话框"包含3个EditText和1个Spinner，我的布局"customspinner"仅包含一个TextView.

My Layout "dialog" contains 3 EditText and 1 Spinner, my layout "customspinner" constains only a TextView.

当我在Android 2.3上执行我的应用程序时，出现以下异常:致命异常:com.mypackage.myapss.mainThreadjava.lang.IllegalStateException:ArrayAdapter要求资源ID为TextView...

When I execute my app on Android 2.3 I have the following exception : FATAL EXCEPTION : com.mypackage.myapss.mainThread java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView ...

现在就不用了，但是我在我的应用程序中使用了android support v4库.

Don't now if it's useful but I use the android support v4 library in my app.

推荐答案

您需要使用此ArrayAdapter构造函数.

You need to use this ArrayAdapter Constructor.

ArrayAdapter(Context context, int resource, int textViewResourceId, List<T> objects);

ArrayAdapter<String> adapterList = new ArrayAdapter<String>(getActivity(),  R.layout.customspinnerregul, R.id.tvcustomspinner, al)
