Как добавить значки рядом с заголовками для Android Navigation Drawer

В настоящее время я работаю над приложением Android для 4.2.2, которое использует новый NavigationDrawer. Это работает как шарм за исключением добавления иконок. 

Я нашел некоторый пример кода, в котором представление List становится относительной компоновкой, в которой 2 параллельных массива вкладываются и отображаются с помощью адаптера массива на основе модели меню, так что я думаю, что они синхронизированы.

Вот основная деятельность:

package com.sorin.medisynced.main;

import Android.app.Activity;
import Android.app.SearchManager;
import Android.content.Intent;
import Android.content.res.Configuration;

import Android.support.v4.widget.DrawerLayout;
import Android.view.Menu;

import Android.widget.Toast;

                long id) {
            // Highlight the selected item, update the title, and close the
            // drawer
            // update selected item and title, then close the drawer

            mDrawerLayout.closeDrawer(mDrawerList);

        }

    }

    @Override
    public void setTitle(CharSequence title) {
        mTitle = title;
        getActionBar().setTitle(mTitle);
    }
}

Вот модель меню:

package com.sorin.medisynced.main;


public class NsMenuItemModel {

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

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

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

}

Вот реализация ArrayAdapter:

package com.sorin.medisynced.main;


import Android.content.Context;
import Android.view.LayoutInflater;
import Android.view.View;
import Android.view.ViewGroup;
import Android.widget.ArrayAdapter;
import Android.widget.ImageView;
import Android.widget.TextView;
import com.sorin.medisynced.R;

public class NsMenuAdapter extends ArrayAdapter<NsMenuItemModel> {

    /*
     * public NsMenuAdapter(Context context, int resource, int
     * textViewResourceId, String[] objects) { super(context,
     * R.layout.ns_menu_row, textViewResourceId, objects); }
     */

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

    public void addHeader(int title) {
        add(new NsMenuItemModel(title, -1, true));
    }

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

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

    @Override
    public int getViewTypeCount() {
        return 2;
    }

    @Override
    public int getItemViewType(int position) {
        return getItem(position).isHeader ? 0 : 1;
    }

    @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) {

        NsMenuItemModel item = getItem(position);
        ViewHolder holder = null;
        View view = convertView;

        if (view == null) {
            int layout = R.layout.ns_menu_row;
            if (item.isHeader)
                layout = R.layout.ns_menu_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;        
    }

}

Как я могу упростить подход. Есть ли способ использовать один массив вместо такой сложной структуры.

B.t.w. Вы можете найти мой проект на github в: https://github.com/greenspand/MediSynced

Это медицинское приложение, отсюда и название . Thx y'all.

Вы можете использовать настраиваемое представление списка вместе с адаптером списка для отображения счетчика, кроме элемента списка в ящике. А затем добавьте любой код, который вы хотите, к своему методу счетчика . Вот код, который я реализовал в своем приложении для Android с поддержкой навигации:

класс методов getter/setter для ящика:

package info.aea.drawer;

public class NavDrawerItem {

    private String title;
    private String tag;
    private int icon;
    private String count = "0";
    // boolean to set visibility of the counter
    private boolean isCounterVisible = false;

    public NavDrawerItem(){}

    public NavDrawerItem(String title, String tag, int icon){
        this.title = title;
        this.tag = tag;
        this.icon = icon;
    }

    public NavDrawerItem(String title, String tag, int icon, boolean isCounterVisible, String count){
        this.title = title;
        this.tag = tag;
        this.icon = icon;
        this.isCounterVisible = isCounterVisible;
        this.count = count;
    }

    public String getTitle(){
        return this.title;
    }

    public String getTag(){
        return this.tag;
    }

    public int getIcon(){
        return this.icon;
    }

    public String getCount(){
        return this.count;
    }

    public boolean getCounterVisibility(){
        return this.isCounterVisible;
    }

    public void setTitle(String title){
        this.title = title;
    }

    public void setTag(String tag){
        this.tag = tag;
    }

    public void setIcon(int icon){
        this.icon = icon;
    }

    public void setCount(String count){
        this.count = count;
    }

    public void setCounterVisibility(boolean isCounterVisible){
        this.isCounterVisible = isCounterVisible;
    }

Это адаптер списка, который я использовал для отображения списка. в конце проверьте метод подсчета отображения:

public class NavDrawerListAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<NavDrawerItem> navDrawerItems;

    public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
        this.context = context;
        this.navDrawerItems = navDrawerItems;
    }

    @Override

            convertView = mInflater.inflate(R.layout.drawer_list_item, null);
        }

        imgIcon.setImageResource(navDrawerItems.get(position).getIcon());        
        txtTitle.setText(navDrawerItems.get(position).getTitle());
        txtTag.setText(navDrawerItems.get(position).getTag());

        // displaying count

}

Проще всего это сделать так:

1. Сделать это как ваш ящик XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:Android="http://schemas.Android.com/apk/res/Android"
xmlns:tashan="http://schemas.Android.com/apk/res-auto"
Android:layout_width="match_parent"
Android:layout_height="wrap_content"
Android:minHeight="?android:attr/listPreferredItemHeightSmall"
Android:orientation="horizontal"
Android:padding="@dimen/spacing_small" >

<ImageView
    Android:id="@+id/drawer_item_icons"
    Android:layout_width="wrap_content"
    Android:layout_height="wrap_content"
    Android:layout_gravity="center_vertical"
    Android:layout_marginLeft="@dimen/spacing_small"
    Android:layout_marginStart="@dimen/spacing_small"
    Android:contentDescription="@string/test_string"/>

<TextView
    Android:id="@+id/drawer_item_labels"
    Android:layout_width="match_parent"
    Android:layout_height="wrap_content"
    Android:layout_gravity="center_vertical"
    Android:layout_marginLeft="@dimen/spacing_normal"
    Android:layout_marginStart="@dimen/spacing_small"
    Android:paddingLeft="@dimen/spacing_small"
    Android:paddingRight="@dimen/spacing_small"
    Android:textAppearance="?android:attr/textAppearanceSmall"
    Android:textColor="#58585b" />

</LinearLayout>

2. Добавьте эти значения в ваш «Dimens.xml». Никогда не кодируйте значения жестко!

    <dimen name="spacing_normal">16dp</dimen>
    <dimen name="spacing_small">8dp</dimen>

3. Для массива иконок добавьте этот String Array в 'strings.xml

<string-array name="array_main_menu">
    <item>@drawable/1</item>
    <item>@drawable/2</item>
    <item>@drawable/3</item>
    <item>@drawable/4</item>
    <item>@drawable/5</item>
</string-array>

4. В вашем адаптере получить доступ к этому массиву с помощью экземпляра Typed Array.

    TypedArray typedArray=getResources().obtainTypedArray(R.array.array_main_menu);

5. Внутри getView вашего адаптера установите изображение на Imageview следующим образом.

 mIcon.setImageResource(typedArray.getResourceId(position, -1));

здесь mIcon - это ваш ImageView.

В последних версиях библиотеки поддержки самый простой способ - использовать NavigationView. Вот хороший учебник , и вот официальная документация .

NavigationView включен в качестве второго представления в DrawerLayout (вместо ListView из кода OP), например:

     <Android.support.design.widget.NavigationView
     Android:id="@+id/navigation"
     Android:layout_width="wrap_content"
     Android:layout_height="match_parent"
     Android:layout_gravity="start"
     app:menu="@menu/left_menu" />

Затем меню должно быть заполнено заголовками и значками, например (left_menu.xml):

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:Android="http://schemas.Android.com/apk/res/Android">
<group
    Android:id="@+id/leftMenuId"
    Android:checkableBehavior="single">
    <item
        Android:id="@+id/item1"
        Android:icon="@drawable/ic_zzblack_24dp"
        Android:title="Title1" />
    <item
        Android:id="@+id/settings"
        Android:icon="@drawable/ic_settings_black_24dp"
        Android:title="Settings" />
</group>
</menu>
