Android – Material design tutorial -7 ( NavigationView )

In this tutorial, we will discuss about navigation view. Using Navigation View which was introduced with android design support library, we can create a navigation drawer easily that comply with the Navigation Drawer Design Guideline .

 

navigation

 

Create one project in android studio with activity MainActivity.java and layout resource file for this activity as activity_main.xml
 
NavigationView is added inside DrawerLayout . It contains all the navigation drawer items and one Header view (Top View containing user image, user name and user email )
 
Drawer items and Navigation Header can be loaded into the DrawerLayout manually or programatically.
Manually : Using app:menu and app:headerLayout
Programatically : Using navigationView.inflateHeaderView() and navigationView.inflateMenu()
 
In this example, we are inflating navigation items manually and header programatically.
 
1. We will use Glide for loading and CircleImageView library for user image . i.e. build.gradle dependencies will be like:
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:design:23.2.1'
    compile 'de.hdodenhof:circleimageview:2.0.0'
    compile 'com.github.bumptech.glide:glide:3.7.0'
    compile 'com.android.support:support-v4:23.2.1'
}
2. Edit your activity_main.xml file as :
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.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:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

2. Create app_bar_main.xml that will contain the ToolBar

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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:fitsSystemWindows="true"
    tools:context="com.codevscolor.navigationviewdemo.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_main" />

</android.support.design.widget.CoordinatorLayout>

contain_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:background = "#263238"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.codevscolor.navigationviewdemo.MainActivity"
    tools:showIn="@layout/app_bar_main">

</RelativeLayout>

4. Create nav_header_main.xml file for header view

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/nav_header"
    android:layout_width="match_parent"
    android:layout_height="@dimen/nav_header_height"
    android:gravity="bottom"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">


    <de.hdodenhof.circleimageview.CircleImageView
        android:id="@+id/user_image"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="@dimen/activity_vertical_margin" />

    <TextView
        android:id="@+id/name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/user_image"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:text="Nandan Kaushik"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

    <TextView
        android:id="@+id/email"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/name"
        android:text="codevscolor@gmail.com" />

</RelativeLayout>

5. Create one menu xml file activity_main_drawer.xml that will be used by the Navigation View as navigation drawer items.

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

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_camera"
            android:icon="@drawable/ic_menu_camera"
            android:title="Import" />
        <item
            android:id="@+id/nav_gallery"
            android:icon="@drawable/ic_menu_gallery"
            android:title="Gallery" />
        <item
            android:id="@+id/nav_slideshow"
            android:icon="@drawable/ic_menu_slideshow"
            android:title="Slideshow" />
        <item
            android:id="@+id/nav_manage"
            android:icon="@drawable/ic_menu_manage"
            android:title="Tools" />
    </group>

    <item android:title="Communicate">
        <menu>
            <item
                android:id="@+id/nav_share"
                android:icon="@drawable/ic_menu_share"
                android:title="Share" />
            <item
                android:id="@+id/nav_send"
                android:icon="@drawable/ic_menu_send"
                android:title="Send" />
        </menu>
    </item>

</menu>

4. Finally change our MainActivity.java as

public class MainActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {

    private CircleImageView userImage;
    private RelativeLayout backImage;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);

        //inflate header view
        final View headerLayout = navigationView.inflateHeaderView(R.layout.nav_header_main);
     
        userImage = (CircleImageView) headerLayout.findViewById(R.id.user_image);
        backImage = (RelativeLayout) headerLayout.findViewById(R.id.nav_header);

        //load background image and user image using glide
        Glide.with(this).load(R.drawable.me).into(userImage);
        backImage.setBackground(getResources().getDrawable(R.drawable.background));
    }

    @Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @SuppressWarnings("StatementWithEmptyBody")
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        int id = item.getItemId();

        if (id == R.id.nav_camera) {
            // Handle the camera action
            Toast.makeText(this, "Clicked on camera", Toast.LENGTH_SHORT).show();
        } else if (id == R.id.nav_gallery) {
            Toast.makeText(this, "Clicked on gallery", Toast.LENGTH_SHORT).show();
        } else if (id == R.id.nav_slideshow) {
            Toast.makeText(this, "Clicked on slideshow", Toast.LENGTH_SHORT).show();
        } else if (id == R.id.nav_manage) {
            Toast.makeText(this, "Clicked on tools", Toast.LENGTH_SHORT).show();
        } else if (id == R.id.nav_share) {
            Toast.makeText(this, "Clicked on share", Toast.LENGTH_SHORT).show();
        } else if (id == R.id.nav_send) {
            Toast.makeText(this, "Clicked on send", Toast.LENGTH_SHORT).show();
        }

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }
}
  •  we are using navigationView.inflateHeaderView(R.layout.nav_header_main);to inflate the header view nav_header_main.xml
  • MainActivity is implementing NavigationView.OnNavigationItemSelectedListenerand overriding public boolean onNavigationItemSelected(MenuItem item)method, inside which navigation item clicks are handled.
  • We are using Glide library to load the user image Glide.with(this).load(R.drawable.me).into(userImage);

That’s it . You can pull these project from Github Here.
