Question

好吧基本上我有自定义 ListView 和 onClick 的列表项（按钮）我想打开一个对话框，它应该基本上显示另一个ListView。我可以查看两个列表，但问题是我的对话框列表视图没有在对话框中显示列表。它只是一个透明的列表在上一个列表的顶部。但是如果尝试设置Dialog Title getDialog().setTitle("Apps List");我会得到上面提到的错误，这意味着我在第一个地方没有对话但是为什么？。

public class ProfileDialog extends android.support.v4.app.DialogFragment {
     .........
       @Override
       public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

            ArrayList<String> listItemTitle = new ArrayList<String>();
            listItemTitle.add("Hello");
            listItemTitle.add("Hello1");
            listItemTitle.add("Hello2");
            listItemTitle.add("Hello3");
            ArrayList<String> listItemType = new ArrayList<String>();
            listItemType.add("Hello");
            listItemType.add("Hello123");
            listItemType.add("1234");
            listItemType.add("Hello6666");
            ArrayList<Integer> listItemId = new ArrayList<Integer>();
            listItemId.add(1);
            listItemId.add(2);
            listItemId.add(3);
            listItemId.add(4);
            ArrayList<Profile> ProfileArrayList = new ArrayList<>();

            for (int i = 0; i < listItemTitle.size(); i++) {
                Profile Profile = new Profile(listItemTitle.get(i), listItemType.get(i), listItemId.get(i));
                ProfileArrayList.add(Profile);

            }

            View   profileView = inflater.inflate(R.layout.fragment_profile_dialog, container, false);
            ListView   profileListView = (ListView) profileView.findViewById(R.id.lstvSelectedProfile);
            getDialog().setTitle("Apps List");
    //        ListView   profileListView = (ListView) LayoutInflater.from(context).inflate(R.layout.fragment_profile_dialog, null);
            if(profileListView.getParent()!=null) {
                ((ViewGroup) profileListView.getParent()).removeView(profileListView);
            }
                SelectedProfileListAdapter adapter = new SelectedProfileListAdapter(getActivity().getApplicationContext(), ProfileArrayList);
                profileListView.setAdapter(adapter);


            return profileListView;
        }

这是我的Adapater填充了第二个列表。

public class SelectedProfileListAdapter extends BaseAdapter{
    private LayoutInflater layoutInflater;
    private List<Profile> selectedProfileList;

    public SelectedProfileListAdapter(Context context, List<Profile> selectedProfileList) {
        layoutInflater =(LayoutInflater) context.getSystemService(LAYOUT_INFLATER_SERVICE);
        this.selectedProfileList = selectedProfileList;
//        this.context = context;
    }

...........
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ProfilesListAdapter.ViewHolder ProfileListViewHolder;
        if (convertView == null) {
            ProfileListViewHolder = new ProfilesListAdapter.ViewHolder();
            convertView = layoutInflater.inflate(R.layout.adapter_profiles_list, parent, false);
            ProfileListViewHolder.title = (TextView) convertView.findViewById(R.id.title);
            ProfileListViewHolder.textView3 = (TextView) convertView.findViewById(R.id.textView3);
            ProfileListViewHolder.imageButtonMore = (ImageButton) convertView.findViewById(R.id.imgButtonMore);
            convertView.setTag(ProfileListViewHolder);
        } else {
            ProfileListViewHolder = (ProfilesListAdapter.ViewHolder) convertView.getTag();
        }
        ProfileListViewHolder.textView3.setText(selectedProfileList.get(position).getTitle());
        ProfileListViewHolder.title.setText(selectedProfileList.get(position).getType());
        ProfileListViewHolder.imageButtonMore = (ImageButton) convertView.findViewById(R.id.imgButtonMore);
        ProfileListViewHolder.imageButtonMore.setTag(selectedProfileList.get(position).getId());


        return convertView;
    }

}

您可以覆盖onCreateDialog()方法并在那里添加标题......

  @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.setTitle("Apps List");
    return dialog;
}

修改

res / styles.xml中的
：添加自定义对话框样式

<style name="CustomDialog" parent="@style/Theme.AppCompat.Light.Dialog"> <item name="android:windowNoTitle">false</item> </style>

现在使用：在您的父片段
中应用它
ProfileDialog fragment = new ProfileDialog(); fragment.setStyle(DialogFragment.STYLE_NORMAL, R.style.CustomDialog);

无法使用对话框片段
