NavigationView example in Android

Hi guys, You can use NavigationView from android material design for slide menu in android.


DrawerLayout xml
<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/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/drawer_header"
        app:itemIconTint="@color/colorPrimary"
        app:itemTextAppearance="@layout/menu_text_style"
        app:menu="@menu/drawer" />

</android.support.v4.widget.DrawerLayout>
And your drawer header is normal layout, sample header layout drawer_header.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:padding="@dimen/activity_vertical_margin"
    android:background="@drawable/bg"
    android:orientation="horizontal">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/app_name"
        android:src="@drawable/ic_account_circle_white_24dp" />

    <TextView
        android:id="@+id/txtName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="6dp"
        android:layout_marginStart="6dp"
        android:textAppearance="@style/TextAppearance.AppCompat.Headline"
        android:textColor="@android:color/white" />

</LinearLayout>
And your drawer menu is normal menu resource, sample menu resource code menu.xml
<?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/navigation_item_1"
            android:icon="@drawable/ic_home_white_24dp"
            android:title="@string/title_home" />
        <item
            android:id="@+id/navigation_item_2"
            android:icon="@drawable/ic_bookmark_white_24dp"
            android:title="@string/title_bookmarks" />
        <item
            android:id="@+id/navigation_item_3"
            android:icon="@drawable/ic_favorite_white_24dp"
            android:title="@string/title_favorite" />
        <item
            android:id="@+id/navigation_item_4"
            android:icon="@drawable/ic_payment_white_24dp"
            android:title="@string/title_payment" />
        <item
            android:id="@+id/navigation_item_5"
            android:icon="@drawable/ic_settings_white_24dp"
            android:title="@string/title_settings" />
    </group>
</menu>
And you can get this header layout in your java code as like
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
TextView txtName = (TextView) navigationView.getHeaderView(0).findViewById(R.id.txtName);
txtName.setText(getResources().getString(R.string.title_name));
And you have to implement NavigationView.OnNavigationItemSelectedListener to access the click event of menu items like,
navigationView.setNavigationItemSelectedListener(this);
And, Yes, this interface has the method, it should be implemented as like,
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        int id = item.getItemId();
        int position = 0;
        switch (id) {
            case R.id.navigation_item_1:
                mTitle = getString(R.string.title_home);
                position = 0;
                break;
            case R.id.navigation_item_2:
                mTitle = getString(R.string.title_bookmarks);
                position = 1;
                break;
            case R.id.navigation_item_3:
                mTitle = getString(R.string.title_favorite);
                position = 2;
                break;
            case R.id.navigation_item_4:
                mTitle = getString(R.string.title_payment);
                position = 3;
                break;
            case R.id.navigation_item_5:
                mTitle = getString(R.string.title_settings);
                position = 4;
                break;
        }
        if (getSupportActionBar() != null)
            getSupportActionBar().setTitle(mTitle);
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
                .commit();
        
        return true;
    }
