Abschnitt-Header in der Navigation Drawer Listview

Hier ist, wie ich es gelöst:

Unterrichtete ich meine eigenen ListAdapter zurückkehren überschrift Zeilen sowie Zeilen detail beinhaltet dies das überschreiben von Methoden getViewTypeCount() und getItemViewType() in der ListAdapter, plus ich habe getView (), den Unterschied zu kennen zwischen den Zeilen-Arten. Der folgende code sollte Euch einen Hinweis geben..Der code für ListViewAdapter (kommentierte den meisten teilen)

public class ListViewAdapter extends ArrayAdapter<ListViewItemModel> {

public ListViewAdapter(Context context) {
    super(context, 0);
}

public void addHeader(int title) { //expects The Title for the header as an Arugment to it
    add(new ListViewItemModel(title, -1, true));//add the object to the Bottom of the array
}

public void addItem(int title, int icon) {
    add(new ListViewItemModel(title, icon, false));
}

public void addItem(ListViewItemModel itemModel) {
    add(itemModel);
}

@Override
public int getViewTypeCount() {  //Returns the number of types of Views that will be created by getView(int, View, ViewGroup).
    return 2; //we will create 2 types of views
}

@Override
public int getItemViewType(int position) { //framework calls getItemViewType for row n, the row it is about to display.
    //Get the type of View that will be created by getView(int, View, ViewGroup) for the specified item.
    return getItem(position).isHeader ? 0 : 1; //get position passes (n) and accertain  is its a header  or not
}

@Override
public boolean isEnabled(int position) {
    return !getItem(position).isHeader;
}

public static class ViewHolder {
    public final TextView textHolder;
    public final ImageView imageHolder;

    public ViewHolder(TextView text1, ImageView image1) {
        this.textHolder = text1;
        this.imageHolder = image1;
    }
}

public View getView(int position, View convertView, ViewGroup parent) {
  //Abstract View --> Get a View that displays the data at the specified position in the data set.
    ListViewItemModel item = getItem(position);
    ViewHolder holder = null;
    View view = convertView;

    if (view == null) {
        int layout = R.layout.list_view_row;
        if (item.isHeader)
            layout = R.layout.list_view_row_header;

        view = LayoutInflater.from(getContext()).inflate(layout, null);

        TextView text1 = (TextView) view.findViewById(R.id.menurow_title);
        ImageView image1 = (ImageView) view.findViewById(R.id.menurow_icon);
        view.setTag(new ViewHolder(text1, image1));
    }

    if (holder == null && view != null) {
        Object tag = view.getTag();
        if (tag instanceof ViewHolder) {
            holder = (ViewHolder) tag;
        }
    }

    if (item != null && holder != null) {
        if (holder.textHolder != null)
            holder.textHolder.setText(item.title);

        if (holder.imageHolder != null) {
            if (item.iconRes > 0) {

                holder.imageHolder.setVisibility(View.VISIBLE);
                holder.imageHolder.setImageResource(item.iconRes);
            } else {
                holder.imageHolder.setVisibility(View.GONE);
            }
        }
    }

    return view;
}

}

Und ein Modell für den ArrayAdapter verwenden

 public class ListViewItemModel {

public int title;
public int iconRes;
public boolean isHeader;

public ListViewItemModel(int title, int iconRes, boolean header) {
    this.title = title;
    this.iconRes = iconRes;
    this.isHeader = header;
}

public ListViewItemModel(int title, int iconRes) {
    this(title, iconRes, false);
}

}

Nun in der Klasse, ich werde mich mit diesem custom listview in der navigation

ListViewAdapter mAdapter = new ListViewAdapter(this);//Add First Header        
mAdapter.addHeader(R.string.menu_data);
menu_One = getResources().getStringArray(R.array.menu_one); //Load list view data     array strings
    String[] menuOneIcons =   getResources().getStringArray(R.array.menu_two_one);//Load list view image array strings


    int oneIcons = 0;
    for (String item : menuItemsData) { //enhanced For loop, iterate on elements from the collection named menuItemsData

        int id_menu_one = getResources().getIdentifier(item, "string",this.getPackageName());

        int id_menu_one_icons = getResources().getIdentifier(menuOneIcons[oneIcons], "drawable",this.getPackageName());



        ListViewItemModel mItem = new ListViewItemModel(id_data_title,id_data_icon);

        mAdapter.addItem(mItem);
        oneIcons++;
    }
    //Add second header

    mAdapter.addHeader(R.string.menu_two); //second Header here

    menu_Two = getResources().getStringArray(R.array.menu_two);
    String[] menuTwoIcons = getResources().getStringArray(R.array._menu_two_icons);


    int twoIcons = 0;
    for (String item : menu_Two) {

        int id_menu_two = getResources().getIdentifier(item, "string",this.getPackageName());

        int id_menu_two_icons = getResources().getIdentifier(enuTwoIcons[twoIcons], "drawable",this.getPackageName());


        //creating drawer menu model
        ListViewItemModel mItem = new ListViewItemModel(id_menu_two,id_menu_two_icons);

        mAdapter.addItem(mItem);
        twoIcons++;
    }
