How to Add icons adjacent to titles for Android Navigation Drawer

here's my layout:

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content" >

  <ImageView
    android:id="@+id/drawer_item_icon"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_marginLeft="10sp"
    android:layout_marginRight="10sp"
    android:src="@drawable/ic_launcher" />

  <TextView
    android:id="@+id/drawer_item_text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:textSize="25sp"
    android:paddingTop="8sp"
    android:paddingBottom="8sp"
    android:paddingLeft="15sp" />

</LinearLayout>

You can use a custom list view along with the list adapter to display the counter besides the list item in the drawer. And then add whatever code you want to your counter method. Here's the code I implemented in my navigation drawer supported android app :

getter/setter methods class for the drawer :

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;
    }
}

This is the list adapter I used to display the list. check the display count method in the end :

package info.aea.drawer;

import info.aea.snippets.R;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

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
    public int getCount() {
        return navDrawerItems.size();
    }

    @Override
    public Object getItem(int position) {       
        return navDrawerItems.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater mInflater = (LayoutInflater)
                    context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
            convertView = mInflater.inflate(R.layout.drawer_list_item, null);
        }

        ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
        TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
        TextView txtTag = (TextView) convertView.findViewById(R.id.tag);
        TextView txtCount = (TextView) convertView.findViewById(R.id.counter);

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

        // displaying count
        // check whether it set visible or not
        if(navDrawerItems.get(position).getCounterVisibility()){
            txtCount.setText(navDrawerItems.get(position).getCount());
        }else{
            // hide the counter view
            txtCount.setVisibility(View.GONE);
        }

        return convertView;
    }

}

Corresponding list layout :

        android:layout_marginRight="12dp"
        android:contentDescription="@string/desc_list_item_icon"
        android:src="@drawable/ic_home"

        android:layout_centerVertical="true"
        android:layout_marginRight="8dp"

    }


    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent result) {
       super.onActivityResult(requestCode, resultCode, result);
    }
}

Simplest way I did it is this way:

1. Make this as your drawer 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. Add these values to your 'dimens.xml'. Never hardcode values!

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

3. For Icons array add this String Array to '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. In your Adapter access this array by using a Typed Array instance.

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

5. Inside the getView of your adapter, set image to Imageview like this.

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

here mIcon is your ImageView.

With recent versions of Support Library, the easiest way is to use a NavigationView. Here is a nice tutorial, and here is the official documentation.

A NavigationView is included as second view in the DrawerLayout (instead of ListView from OP code), for example:

     <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" />

Then, the menu should be populated with titles and icons, like (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>
