Answer 1

You need to create your own adapter, define the layout of it's items so that it contains the icon and text, as you want, and then set it as the adapter of your drawer list.

So you need to modify your drawer_list_item.xml to contain a horizontal LinearView , with the icon ImageView and the label TextView .

Here is an implementation I did for one of my projects that does exactly what you need to do:

import android.content.Context;
import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.annotation.DrawableRes;
import android.support.annotation.StringRes;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.view.LayoutInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;

public abstract class DrawerActivity extends BaseActivity {

    private static List<DrawerItem> sDrawerItems;

    private ActionBarDrawerToggle mDrawerToggle;

    public ActionBarDrawerToggle getDrawerToggle() {
        return mDrawerToggle;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setUpDrawerList();
        setUpDrawerToggle();
    }

    private void setUpDrawerToggle() {
        final DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_container);
        mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, getToolbar(),
            R.string.drawer_open, R.string.drawer_close);
        drawerLayout.addDrawerListener(mDrawerToggle);
    }

    private void setUpDrawerList() {
        final DrawerAdapter drawerAdapter = new DrawerAdapter(this, getDrawerItems(), getClass());
        final int selectedPosition = drawerAdapter.getCurrentItemPosition();
        final ListView drawerList = (ListView) findViewById(R.id.drawer_list);
        drawerList.setAdapter(drawerAdapter);
        drawerList.setItemChecked(selectedPosition, true);
        drawerList.setOnItemClickListener(new DrawerItemOnClickListener());
    }

    @Override
    public void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);

        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override

    }

    private static List<DrawerItem> getDrawerItems() {
        if (sDrawerItems == null) {
            sDrawerItems = new ArrayList<>();
            sDrawerItems.add(new DrawerItem(R.drawable.ic_today_black_24dp, R.string.calendar_title,
                BaseCalendarActivity.class));
            sDrawerItems.add(new DrawerItem(R.drawable.ic_face_black_24dp, R.string.profile_title, null));

    }

    // Encapsulates the information about a drawer item
    protected static class DrawerItem {

Answer 2

cabinet_list_item是列表视图的布局..在textview之前添加一个imageview ..创建一个与mplanettitles相同的图像数组，但制作一个drawables ..看起来像int [] mplanetimages = [r.drawable.something]然后创建一个自定义适配器..然后将字符串数组和图像的int数组传递给适配器，然后在适配器内部进行设置

Answer 3

Thank you all. I found answer on another forum. cyberforum.ru

hier we go.

You need your own Adapter where you put your icons and labels and than you bind it to your view.

So class MenuItem with data , icons and title

public class MenuItem {
    private  String title;
    private int imageId;

    public String getTitle() {
        return title;
    }

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

    public int getImageId() {
        return imageId;
    }

    public void setImageId(int imageId) {
        this.imageId = imageId;
    }
}

Transfer your created class to adpater and create menuHolder that binds to View

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 java.util.List;

    /**
     * Created by vklamm on 08.04.2016.
     * transfer hier MenuItem class
     * create Menu holder and bind it to view
     */
    public class MyAdapter extends ArrayAdapter<MenuItem> {

        private int resource;
        private List<MenuItem> data;
        private Context context;
        private MenuHolder menuHolder;

        public MyAdapter(Context context, int resource, Context context1) {
            super(context, resource);
            context = context1;
        }

        public MyAdapter(Context context, int resource, List<MenuItem> data) {
            super(context, resource, data);
            this.context = context;
            this.resource = resource;
            this.data = data;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            if(convertView==null){
                LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                convertView = layoutInflater.inflate(resource,parent,false);

                menuHolder = new MenuHolder();

                //create drawer_list_item layout where ours icons and labels are
                menuHolder.menuItemImg = (ImageView) convertView.findViewById(R.id.menuItemImg);
                menuHolder.menuItemTitle = (TextView) convertView.findViewById(R.id.menuItemTitle);
                convertView.setTag(menuHolder);
            }else {
                menuHolder = (MenuHolder) convertView.getTag();
            }

            MenuItem menuItem = data.get(position);
            if(menuItem!=null){
                menuHolder.menuItemImg.setImageResource(menuItem.getImageId());
                menuHolder.menuItemTitle.setText(menuItem.getTitle());
            }

            return convertView;
        }
        //created class for binding our icons and texts from view
        public class MenuHolder {
            ImageView menuItemImg;
            TextView menuItemTitle;
        }
    }

modifites/change drawer_list_item.xml to

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/menuItemImg" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:id="@+id/menuItemTitle" />
</LinearLayout>

now add to Settings.class

List<de.magnum_gmbh.mw.MenuItem> menuItems = new ArrayList<>();
        //create your elements of navigation drawer
        de.magnum_gmbh.mw.MenuItem menuItem = new de.magnum_gmbh.mw.MenuItem();
String[] titles = {"Addresses", "Articles", "Invoices","Orders","Settings"};
        Integer[] images = {R.drawable.contacts,R.drawable.articles,R.drawable.invoices,R.drawable.orders,R.drawable.settings};
        for(int i=0;i<5;i++) {
            menuItem.setImageId(images[i]);
            menuItem.setTitle(title[i]);
            menuItems.add(menuItem);
            }
        //initialize your own adapter 
        mDrawerList.setAdapter(new MyAdapter(this, R.layout.drawer_list_item, menuItems));
        // Set the list's click listener
        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
