In this tutorial we’ll implement a Navigation Drawer in our android application. Android navigation drawer is a sliding menu and it’s an important UI component. You will see navigation drawer in most of the android applications, it’s like navigation menu bars in the websites.
Table of Contents
Android Navigation Drawer is a sliding left menu that is used to display the important links in the application. Navigation drawer makes it easy to navigate to and fro between those links. It’s not visible by default and it needs to opened either by sliding from left or clicking its icon in the ActionBar.
In broader terms, Navigation Drawer is an overlay panel, which is a replacement of an activity screen which was specifically dedicated to show all the options and links in the application.
In this android navigation drawer tutorial we’ll implement the navigation drawer using the Drawer Layout API present in Android Support Library. We’ll show 3 fragment views that can be opened from the drawer items.
To implement the Navigation Drawer we first need to add android.support.v4.widget.DrawerLayout as the root of the activity layout as shown below.
activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="https://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="@+id/container_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:id="@+id/toolbar"
layout="@layout/toolbar" />
</LinearLayout>
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFFFFF"
android:choiceMode="singleChoice"
android:divider="@android:color/darker_gray"
android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>
The menu options in the navigation drawer are stored in the form of a ListView. Each option opens in the FrameLayout.
We’ve used a ToolBar in place of an ActionBar here. ToolBar has been introduced since Android 5.0 as a generalisation of ActionBar. It gives us more control and flexibility to modify and its easier to interleave with other views in the hierarchy.
The layout ToolBar is defined in the xml layout given below.
toolbar.xml
<android.support.v7.widget.Toolbar xmlns:android="https://schemas.android.com/apk/res/android"
xmlns:local="https://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
We need to use the Theme Theme.AppCompat.NoActionBar in the styles.xml when using Toolbars.
The layout for the ListView rows in the Navigation Drawer is given below.
list_view_item_row.xml
<RelativeLayout xmlns:android="https://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/activatedBackgroundIndicator"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:padding="10dp" >
<ImageView
android:id="@+id/imageViewIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:paddingRight="10dp" />
<TextView
android:id="@+id/textViewName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="@+id/imageViewIcon"
android:paddingRight="10dp"
android:text="Item Name"
android:textColor="@android:color/black"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
/>
</RelativeLayout>
The navigation drawer items are put in a string array in the strings.xml file as shown below.
strings.xml
<string-array name="navigation_drawer_items_array">
<item>Connect</item>
<item>Fixtures</item>
<item>Table</item>
</string-array>
The DataModel.java class is used to define the objects for the drawer list items.
DataModel.java
package com.journaldev.navigationdrawer;
public class DataModel {
public int icon;
public String name;
// Constructor.
public DataModel(int icon, String name) {
this.icon = icon;
this.name = name;
}
}
The drawer items are stored in the form of a ListView. Hence we need to use an Adapter Class to provide that data to the activity class.
DrawerItemCustomAdapter.java
package com.journaldev.navigationdrawer;
import android.app.Activity;
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;
public class DrawerItemCustomAdapter extends ArrayAdapter<DataModel> {
Context mContext;
int layoutResourceId;
DataModel data[] = null;
public DrawerItemCustomAdapter(Context mContext, int layoutResourceId, DataModel[] data) {
super(mContext, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.mContext = mContext;
this.data = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View listItem = convertView;
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
listItem = inflater.inflate(layoutResourceId, parent, false);
ImageView imageViewIcon = (ImageView) listItem.findViewById(R.id.imageViewIcon);
TextView textViewName = (TextView) listItem.findViewById(R.id.textViewName);
DataModel folder = data[position];
imageViewIcon.setImageResource(folder.icon);
textViewName.setText(folder.name);
return listItem;
}
}
The MainActivity.java source code is given below.
MainActivity.java
package com.journaldev.navigationdrawer;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
public class MainActivity extends AppCompatActivity {
private String[] mNavigationDrawerItemTitles;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
Toolbar toolbar;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
android.support.v7.app.ActionBarDrawerToggle mDrawerToggle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mNavigationDrawerItemTitles= getResources().getStringArray(R.array.navigation_drawer_items_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
setupToolbar();
DataModel[] drawerItem = new DataModel[3];
drawerItem[0] = new DataModel(R.drawable.connect, "Connect");
drawerItem[1] = new DataModel(R.drawable.fixtures, "Fixtures");
drawerItem[2] = new DataModel(R.drawable.table, "Table");
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setHomeButtonEnabled(true);
DrawerItemCustomAdapter adapter = new DrawerItemCustomAdapter(this, R.layout.list_view_item_row, drawerItem);
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.setDrawerListener(mDrawerToggle);
setupDrawerToggle();
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new ConnectFragment();
break;
case 1:
fragment = new FixturesFragment();
break;
case 2:
fragment = new TableFragment();
break;
default:
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(mNavigationDrawerItemTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
Log.e("MainActivity", "Error in creating fragment");
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void setTitle(CharSequence title) {
mTitle = title;
getSupportActionBar().setTitle(mTitle);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
void setupToolbar(){
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
void setupDrawerToggle(){
mDrawerToggle = new android.support.v7.app.ActionBarDrawerToggle(this,mDrawerLayout,toolbar,R.string.app_name, R.string.app_name);
//This is necessary to change the icon of the Drawer Toggle upon state change.
mDrawerToggle.syncState();
}
}
In the above code getSupportActionBar().setDisplayHomeAsUpEnabled(false); is used to hide the default back button.
In this code we’ve used a DrawerItemClickListener Class that loads the respective fragment of the list item clicked using a FragmentManager. Also the the title of the ToolBar is changed to the list item clicked using setTitle(mNavigationDrawerItemTitles[position]);.
The fragment classes and their respective layouts are given below.
ConnectFragment.java
package com.journaldev.navigationdrawer;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class ConnectFragment extends Fragment {
public ConnectFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_connect, container, false);
return rootView;
}
}
The layout of the above fragment is defined below.
fragment_connect.xml
<RelativeLayout xmlns:android="https://schemas.android.com/apk/res/android"
xmlns:tools="https://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/label"
android:layout_alignParentTop="true"
android:layout_marginTop="100dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:textSize="45dp"
android:text="Connect"
android:textStyle="bold"/>
<TextView
android:layout_below="@id/label"
android:layout_centerInParent="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="12dp"
android:layout_marginTop="10dp"
android:gravity="center_horizontal"
android:text="Edit fragment_connect.xml to change the appearance"
android:id="@+id/textView2" />
</RelativeLayout>
The other two items are defined in exactly the same way as above hence we’re skipping it here.
Below is the output produced by our navigation drawer android example application.
This brings an end to android navigation drawer example tutorial. You can download the final Android Navigation Drawer Project from the below link.
how can i add header in it. if i add header it repeated again and again

The above is my android monitor log, My app is not running it is getting crashed, please help
drawerItem[0] = new DataModel(R.drawable.connect, “Connect”);
drawerItem[1] = new DataModel(R.drawable.fixtures, “Fixtures”);
drawerItem[2] = new DataModel(R.drawable.table, “Table”);
The above three line are giving me error what do I have to put in the drawable folder to correct this ??, I have not downloaded your project instead copied the code to android studio
download any three icons and name them
Connect,Fixtures,Table
respectively
hello sir,
its showing me error:
switch (position) {
case 0:
fragment = new Fragment();
break;
case 1:
fragment = new FixturesFragment();
break;
case 2:
fragment = new TableFragment();
break;
default:
break;
}
Error: cannot resolve symbol TableFragment()
have you created TableFragment class in your project check it?
R.drawable.connect Its showing an error… Where to set it in drawable xml files
plz explain
Can you share an example how to communicate with more fragments in this case ????
For example, after the user connects the another fragment UI appears or something like that, please?? I am new and I am learning lot, but your tutorial is the perfect one I have so far found 😉

How can I change the code in MainActivity.java so that I can replace the fragmentMenager with the ListFragment instead of just Fragment? IS that possible? Because I need that implementation, please. Thanks in advance
I just figured it out 😉 .
in the MainActivity.java I have modified this method:
private void selectItem(int position) {
Fragment fragment = null;
ListFragment listFragment = null;
switch (position) {
case 0:
fragment = new ConnectFragment();
break;
case 1:
fragment = new FixturesFragment();
break;
case 2:
listFragment = new TableFragment();
break;
default:
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(mNavigationDrawerItemTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else if(listFragment != null){
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, listFragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(mNavigationDrawerItemTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
else {
Log.e(“MainActivity”, “Error in creating fragment”);
}
}
and also in the xml file for the table fragment_table.xml I have replaced inside the RelativeLayot as the following:
Hello, good afternoon
I have a doubt
I have the previous menu, but I want to add a google map to all the menu options with their respective current location, how can I do it?
This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

Hi,
Set this in your styles.xml :
false

Hi md zaid,
Can you do a clean build and then see if it works?
Also, can you ensure that your emulator is using Android SDK 15 or above?
Last resort, if the app is crashing, you can post the logs from Android Studio here.
Thanks
ConnectFragment,FixturesFragment,TableFragment these are class names.
first you have to create classs with extend fragments
I need to display menu below the manu bar
below the title bar
Thank you so much dude. I’ve been searching for days for an example like this for a project in a course i’m taking, where i need a navigation drawer and an action bar. you just saved a fellow programmer

How to change theme?
Hi Nunu,
You can change the app theme in the file styles.xml
Thanks
Like the way you explain things 🙂
I think the last 2 lines in MainActivity#onCreate should be swapped :
“`
mDrawerLayout.setDrawerListener(mDrawerToggle); // because mDrawerToggle is null here
setupDrawerToggle();
“`
Thank you

Hi sachin purohit,

I follow this tutorial and awesome!
But I’m searching for right navigation drawer, is there any good tutorial that can be applied for me?
Thanks
I’ll write a tutorial on the same. Soon!
I don’t know if it was posted but here you go..
Put this code snippet in you onCreate before the setContentView();
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
and set the ListViews layout_gravity to right in you xml.
THis is how I managed to do it 🙂
very nice tutorial thank you
but i need extra profile image and name also how to do this
Hi Karthikeyan,
The latest android support library provides us with widget. You can use the sample code from the Navigation Drawer Activity when you create a new project.
Other workarounds:
You can use this library https://github.com/mikepenz/MaterialDrawer by importing the gradle dependency as
compile(‘com.mikepenz:materialdrawer:5.5.0@aar’) {
transitive = true
}
Or instead of using a listview inside the drawer we can use a ReyclerView with Multiple View Types. Randomly use a view type as the header that displays the profile image, details. I’ll be discussing this approach in a separate tutorial soon.
Thanks
