Android Navigation Drawer Example – Source Code

In this tutorial we are going to learn how to use navigation drawer to add a sliding menu to your application.

Downloaded navigation drawer toggle icon and included in drawable folders. Name of Image is “ic_drawer.png”

Step : 1 – res ==> values ==> strings.xml

strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
 
    <string name="app_name">Slider Menu</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    <string name="drawer_open">Slider Menu Opened</string>
    <string name="drawer_close">Slider Menu Closed</string>
     
    <!-- Nav Drawer Menu Items -->
    <string-array name="nav_drawer_items">
        <item >Home</item>
        <item >Find People</item>
        <item >Photos</item>
        <item >Communities</item>
        <item >Pages</item>
        <item >What\'s Hot</item>
    </string-array>
     
    <!-- Nav Drawer List Item Icons -->
    <!-- Keep them in order as the titles are in -->
    <array name="nav_drawer_icons">
        <item>@drawable/ic_home</item>
        <item>@drawable/ic_people</item>
        <item>@drawable/ic_photos</item>
        <item>@drawable/ic_communities</item>
        <item>@drawable/ic_pages</item>
        <item>@drawable/ic_whats_hot</item>
    </array>
     
    <!-- Content Description -->
    <string name="desc_list_item_icon">Item Icon</string>
 
</resources>

Step : 2 – activity_main.xml

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
 
    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
 
    <!-- Listview to display slider menu -->
    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"       
        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>

Step : 3 – res ==> drawable ==> list_item_bg_normal.xml


<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
  <gradient
      android:startColor="@color/list_background"
      android:endColor="@color/list_background"
      android:angle="90" />
</shape>

Step : 4 – res ==> drawable ==> list_item_bg_pressed.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
  <gradient
      android:startColor="@color/list_background_pressed"
      android:endColor="@color/list_background_pressed"
      android:angle="90" />
</shape>

Step : 5 – res ==> drawable ==> list_selector.xml


<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 
    <item android:drawable="@drawable/list_item_bg_normal" android:state_activated="false"/>
    <item android:drawable="@drawable/list_item_bg_pressed" android:state_pressed="true"/>
    <item android:drawable="@drawable/list_item_bg_pressed" android:state_activated="true"/>
 
</selector>

Step : 6 – res ==> drawable ==> counter_bg.xml


<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
 
    <!-- view background color -->
    <solid android:color="@color/counter_text_bg" >
    </solid>
 
    <!-- If you want to add some padding -->
    <padding
        android:right="3dp"
        android:left="3dp" >
    </padding>
 
    <!-- Here is the corner radius -->
    <corners android:radius="2dp" >
    </corners>
 
</shape>

Step : 7 – res ==> layout ==> drawer_list_item.xml.


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="48dp"

        android:layout_marginRight="12dp"
        android:contentDescription="@string/desc_list_item_icon"
        android:src="@drawable/ic_home"
        android:layout_centerVertical="true" />
 
    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_toRightOf="@id/icon"
        android:minHeight="?android:attr/listPreferredItemHeightSmall"
        android:textAppearance="?android:attr/textAppearanceListItemSmall"
        android:textColor="@color/list_item_title"
        android:gravity="center_vertical"
        android:paddingRight="40dp"/>
     
    <TextView android:id="@+id/counter"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/counter_bg"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="8dp"
        android:textColor="@color/counter_text_color"/>
 
</RelativeLayout>

Step : 8 – NavDrawerItem.java


package info.androidhive.slidingmenu.model;
 
public class NavDrawerItem {
     
    private String title;
    private int icon;
    private String count = "0";
    // boolean to set visiblity of the counter
    private boolean isCounterVisible = false;
     
    public NavDrawerItem(){}
 
    public NavDrawerItem(String title, int icon){
        this.title = title;
        this.icon = icon;
    }
     
    public NavDrawerItem(String title, int icon, boolean isCounterVisible, String count){

        this.isCounterVisible = isCounterVisible;
        this.count = count;
    }
     
    public String getTitle(){
        return this.title;
    }
     
    public int getIcon(){
        return this.icon;
    }
     
    public String getCount(){

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

Step : 9 – NavDrawerListAdapter.java


package info.androidhive.slidingmenu.adapter;
 
import info.androidhive.slidingmenu.R;
import info.androidhive.slidingmenu.model.NavDrawerItem;
 
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) {

        ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
        TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
        TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
          
        imgIcon.setImageResource(navDrawerItems.get(position).getIcon());        
        txtTitle.setText(navDrawerItems.get(position).getTitle());

        // 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;
    }
 
}

Step : 10 – HomeFragment.java


package info.androidhive.slidingmenu;
 
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
 
public class HomeFragment extends Fragment {
     
    public HomeFragment(){}
     
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
  
        View rootView = inflater.inflate(R.layout.fragment_home, container, false);
          
        return rootView;
    }
}

Step : 11 – fragment_home.xml


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
     
    <TextView
        android:id="@+id/txtLabel"
         android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:textSize="16dp"
        android:text="Home View"/>
     
    <ImageView android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/txtLabel"
        android:src="@drawable/ic_home"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="10dp"/>
     
 
</RelativeLayout>
