您好我正在使用带有listview的Alert对话框它工作正常但是当我点击列表项时我想要关闭对话框，但它不起作用，以下是我的片段，任何人都可以帮我解决这个问题。

 public void setdailog()

        final AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity());
        // dialog.setContentView(R.layout.alert_list_radio);
        dialog.setTitle("Select Language");
        View customView = LayoutInflater.from(getActivity()).inflate(
                R.layout.alert_list, null, false);

        AlertListAdapter mAdapter = new AlertListAdapter(langList, getActivity());
        listView.setAdapter(mAdapter);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                SELECTED_LANGUAGE = langList.get(position).getLangid();
                System.out.println("JO JO"+SELECTED_LANGUAGE);
               dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {

                    }
                });
            }
        });

尝试类似

的内容

public void setdailog()
{
    final AlterDialog alert;
    final AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity());
    // dialog.setContentView(R.layout.alert_list_radio);
    dialog.setTitle("Select Language");
    View customView = LayoutInflater.from(getActivity()).inflate(
            R.layout.alert_list, null, false);
    ListView listView = (ListView) customView.findViewById(R.id.listiview_lang);
    AlertListAdapter mAdapter = new AlertListAdapter(langList, getActivity());
    listView.setAdapter(mAdapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            SELECTED_LANGUAGE = langList.get(position).getLangid();
            System.out.println("JO JO"+SELECTED_LANGUAGE);
         //  dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
            //    @Override
            //    public void onDismiss(DialogInterface dialog) {
            //        dialog.dismiss();
            //    }
            if (alert != null && alert.isShowing()) {
                alert.dismiss();
               }
            });
        }
    });
    listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    dialog.setView(customView);
    alert = dialog.create();
   alert.show();
}

或

您可以创建如下所示的自定义对话框：

public void setdailog()
{

  Dialog  cpDialog = new Dialog(getActivity());
    cpDialog.setTitle("Select Language");
    cpDialog.setContentView(R.layout.alert_list);

    ListView listView = (ListView) cpDialog.findViewById(R.id.listiview_lang);
    AlertListAdapter mAdapter = new AlertListAdapter(langList, getActivity());
    listView.setAdapter(mAdapter);
    listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            cpDialog.dismiss();

            }
        });
    cpDialog.show();
}
