Navigation Drawer

Navigation Drawer is a side menu panel that consists of different navigating fragments. The menu is provided at the left of the screen which opens and closes as per your user requirements, There are different fragments present in the menu, so when you click on any one fragment it will lead you to a different screen.

The best example would be Gmail App, when you click on the menu a side panel opens up that consists of All Inboxes, Primary, Promotions, and Socials.

Step-by-Step Implementation

Step 1: Open Android Studio, Create New Project, Choose Empty Activity and Name the Project “Navigation Drawer”.

Step 2: colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="purple_200">#FFBB86FC</color>
    <color name="purple_500">#FF6200EE</color>
    <color name="purple_700">#FF3700B3</color>
    <color name="teal_200">#FF03DAC5</color>
    <color name="teal_700">#FF018786</color>
    <color name="black">#FF000000</color>
    <color name="white">#FFFFFFFF</color>
    <color name="lavender">#8692f7</color>
</resources>

Step 3: strings.xml

<resources>
    <string name="app_name">Navigation Drawer</string>
    <string name="open_nav">Open Navigation Drawer</string>
    <string name="close_nav">Close Navigation Drawer</string>
</resources>

Step 4: themes.xml

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.NavigationDrawer" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/lavender</item>
        <item name="colorPrimaryVariant">@color/lavender</item>
        <item name="colorOnPrimary">@color/white</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_700</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>
</resources>

Step 5: AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <application
        android:allowBackup="true"
        android:dataExtractionRules="@xml/data_extraction_rules"
        android:fullBackupContent="@xml/backup_rules"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.NavigationDrawer"
        tools:targetApi="31">
        <activity
            android:name=".MainActivity"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <meta-data
                android:name="android.app.lib_name"
                android:value="" />
        </activity>
    </application>

</manifest>

Step 6: Add Images and Vector Asset in Drawables Folder.

I have added two images, the first is the logo image and the second is the header image.

Further, I have added five vector assets. Icon Name – Home, Settings, Info(About), Exit(Logout), Share.

Step 7: Create four blank fragments and name them as follows:

HomeFragment, SettingsFragment, AboutFragment, ShareFragment.

Step 8: nav_menu.xml

Right-click on res -> Android Resource Directory and select the menu then right-click on the menu directory and click on New -> Menu Resource File and name “nav_menu”.

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:showIn = "navigation_view">

    <group
        android:checkableBehavior="single">

        <item
            android:id="@+id/nav_home"
            android:icon="@drawable/nav_home"
            android:title="Home"/>

        <item
            android:id="@+id/nav_settings"
            android:icon="@drawable/nav_settings"
            android:title="Settings"/>

        <item
            android:id="@+id/nav_share"
            android:icon="@drawable/nav_share"
            android:title="Share"/>

        <item
            android:id="@+id/nav_about"
            android:icon="@drawable/nav_about"
            android:title="About Us"/>
    </group>
    <item
        android:title="">

        <menu>
            <item
                android:id="@+id/nav_logout"
                android:icon="@drawable/nav_logout"
                android:title="Logout"/>
        </menu>

    </item>

</menu>

Step 9: nav_header.xml

Right-click on layout -> Layout Resource File -> nav_header

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="176dp"
    android:gravity="bottom"
    android:padding="16dp"
    android:background="@drawable/headerbkg"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/aklogo"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Android Knowledge"
        android:textColor="@color/white"
        android:textStyle="bold"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="contact@androidknowledge.com"
        android:textColor="@color/white"
        android:textSize="14sp"
        android:layout_marginBottom="16dp"/>

</LinearLayout>

Step 10: activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/drawer_layout"
    android:fitsSystemWindows="true"
    tools:openDrawer="start"
    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <androidx.appcompat.widget.Toolbar
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:id="@+id/toolbar"
            android:elevation="4dp"
            android:background="@color/lavender"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            android:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/fragment_container"/>

    </LinearLayout>

    <com.google.android.material.navigation.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@+id/nav_view"
        android:layout_gravity="start"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/nav_menu"
        app:itemIconTint="@color/lavender"
        app:itemTextColor="@color/lavender"/>

</androidx.drawerlayout.widget.DrawerLayout>

Step 11: All fragments.xml

fragment_home.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        android:textSize="30sp"
        android:layout_centerInParent="true"
        android:textColor="@color/lavender"/>

Step 13: MainActivity.java

package com.example.navigationdrawer;

import androidx.appcompat.app.ActionBarDrawerToggle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
import androidx.core.view.GravityCompat;
