Android Navigation View With Tabs

Android Navigation View With Tabs

In this tutorial we will create a simple app which has a NavigationView, a Toolbar with Tabs and a simple list of items, that are displayed for each selected tab.

Tabs & Navigation lollipop and above

Tools used:

  • Android Studio 2.2 Preview 4
  • Android Emulator 5x API 22

Project

  1. Create a new project by choosing the empty template and then click the Next button until the project is created.
  2. Switch the visibility of project structure by selecting “Project” option like in the image below.
    Android Project Structure

Part 1: NavigationView

First, we will create the NavigationView like explained further in the tutorial.

Summary

  • add compile ‘com.android.support:design:24.0.0’ to dependencies in build.gradle
  • handle theme setup in values – styles.xml
  • handle theme setup in values-v21 – styles.xml
  • set the themes in AndroidManifiest.xml
  • create menu items for NavigationView
  • add strings in strings.xml
  • add dimensions for NavigationView’s header in dimens.xml
  • create the xml file for the NavigationView’s header
  • set TabLayout and NavigationView in the activity_main.xml
  • setup NavigationView in MainActiviy.java

Explanation

  • build.gradle

    In the app module directory, open the build.gradle file and add ‘com.android.support:design:24.0.0’ to dependencies.

    apply plugin: 'com.android.application'
    
    android {
        compileSdkVersion 24
        buildToolsVersion "24.0.0"
        defaultConfig {
            applicationId "com.example.navigationviewtabs"
            minSdkVersion 15
            targetSdkVersion 24
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    
    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        compile 'com.android.support:appcompat-v7:24.0.0'
        compile 'com.android.support:design:24.0.0'
        compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha3'
        testCompile 'junit:junit:4.12'
    }
    
  • Theme setup in values – styles.xml

    Under app – src- main – res – values – styles.xml, set the default AppTheme to support a NoActionBar theme.

    Styles.xml from this directory, will be used for Android versions lower than API Level 21 (Lollipop). Also, keep in mind that for lower versions of Android the status bar won’t be transparent when the NavigationView is opened.

    <resources>
    
        <!-- Base application theme. It will be used to set the theme for the application in AndroidManifest.xml -->
        <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
            <!-- Customize your theme here. -->
            <item name="colorPrimary">@color/colorPrimary</item>
            <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
            <item name="colorAccent">@color/colorAccent</item>
            <item name="windowActionBar">false</item>
            <item name="windowNoTitle">true</item>
        </style>
    
        <!-- This will be used to set the theme for the MainActivity in AndroidManifest.xml-->
        <style name="AppTheme.NoActionBar">
            <item name="windowActionBar">false</item>
            <item name="windowNoTitle">true</item>
        </style>
    
        <!-- This will be used to set the theme for AppBarLayout from activity_main.xml -->
        <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
    
    </resources>
  • Theme setup in values-v21 – styles.xml

    You will have to create this directory because we will use 2 attributes which are available only for Lollipop and above. The directory must be created like this:

  1. Right click on the res directory
  2. Click New – Android resource directory
  3. Select values directory and api level  like in the image below:
    Values v21
  4. Now, inside this directory create a styles.xml file like this:
    1. right click on the values-v21 directory 
    2. click New – Values resource file
    3. write styles.xml
    4. This is the code you should add:
      <resources>
          <style name="AppTheme.NoActionBar">
              <item name="windowActionBar">false</item>
              <item name="windowNoTitle">true</item>
              <item name="android:windowDrawsSystemBarBackgrounds">true</item>
              <item name="android:statusBarColor">@android:color/transparent</item>
          </style>
      </resources>
      

The 2 attributes that are available only from API Level 21 and above are:

  • android:windowDrawsSystemBarBackgrounds: Flag indicating whether this Window is responsible for drawing the background for the system bars. If true and the window is not floating, the system bars are drawn with a transparent background and the corresponding areas in this window are filled with the colors specified in {@link android.R.attr#statusBarColor} and {@link android.R.attr#navigationBarColor}.
  • android:statusBarColor: this will make the status bar transparent when the NavigationView is opened
  • Set themes in AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.navigationviewtabs">
    
        <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:supportsRtl="true"
            android:theme="@style/AppTheme">
            <activity android:name=".MainActivity"
                android:theme="@style/AppTheme.NoActionBar">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
    
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    
    </manifest>
  • Menu items for NavigationView

    Now, we will have to create a menu directory in which we will have to create a xml file containing the NavigationView items.

    1. Right click on the res directory
    2. Click NewAndroid resource directory
    3. Select menu directory menu
    4. Now right click on the menu directory
    5. Click New – Values resource file
    6. Write navigation_items.xml
    7. Add the following code:
      <?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_favorites"
                  android:checked="true"
                  android:title="Item 1"/>
              <item
                  android:id="@+id/navigation_item_categories"
                  android:title="Item 2"/>
              <item
                  android:id="@+id/navigation_item_extra"
                  android:checked="true"
                  android:title="Item 3"/>
          </group>
      </menu>
  • strings.xml

    Add the following strings to res – values – strings.xml

    <resources>
        <string name="app_name">NavigationViewTabs</string>
    
        <string name="navigation_drawer_open">Open navigation drawer</string>
        <string name="navigation_drawer_close">Close navigation drawer</string>
    </resources>

     

  • dimens.xml

    Go to res – values – dimens.xml and add the following code.

    <resources>
        <!-- Default screen margins, per the Android Design guidelines. -->
        <dimen name="nav_header_vertical_spacing">16dp</dimen>
        <dimen name="nav_header_height">160dp</dimen>
        <!-- Default screen margins, per the Android Design guidelines. -->
        <dimen name="activity_horizontal_margin">16dp</dimen>
        <dimen name="activity_vertical_margin">16dp</dimen>
    </resources>
  • nav_header.xml

    Under res – layout create a new xml file and name it nav_header.xml. This layout will be added as header to the NavigationView. It contains 2 texts and an icon (this file is taken from the NavigationView project from Android Studio Templates).

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="@dimen/nav_header_height"
        android:background="@color/colorPrimary"
        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">
    
        <ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingTop="@dimen/nav_header_vertical_spacing"
            app:srcCompat="@android:drawable/sym_def_app_icon" />
    
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingTop="@dimen/nav_header_vertical_spacing"
            android:text="Android Studio"
            android:textAppearance="@style/TextAppearance.AppCompat.Body1" />
    
        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="android.studio@android.com" />
    
    </LinearLayout>
  • activity_main.xml

    In this xml file we will set the NavigationView, toolbar and tabs, using CoordinatorLayout. In the image below, we have described the hierarchy of the views (which view contains which view).

    CoordinatorLayout Hierarchy

    <?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"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">
    
        <android.support.design.widget.CoordinatorLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
    
            <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"
                    app:layout_scrollFlags="scroll|enterAlways" />
    
                <android.support.design.widget.TabLayout
                    android:id="@+id/tab_layout"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:layout_scrollFlags="scroll|enterAlways"
                    app:tabMode="scrollable" />
    
            </android.support.design.widget.AppBarLayout>
    
            <FrameLayout
                android:id="@+id/container"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
        </android.support.design.widget.CoordinatorLayout>
    
        <android.support.design.widget.NavigationView
            android:id="@+id/navigation_drawer"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            app:menu="@menu/navigation_items"
            app:headerLayout="@layout/nav_header"/>
    
    </android.support.v4.widget.DrawerLayout>

    As you can see, DrawerLayout is the root view of this layout and this is the correct way to do it. If you embed DrawerLayout inside other layout (let’s say a RelativeLayout as root view) and you place other UI components outside the DrawerLayout, those UI components will overlap the NavigationView when opened like below:
    DrawerLayout wrong hierarchy

  • Another wrong example, that I did in a project of mine, was that I used CoordinatorLayout as root view instead of DrawerLayout. And because of that, the navigationView was not being opened over the status bar.Also, you have to keep in mind that FrameLayout (the container) will be replaced in Java code with ContainerFragment.java fragment. This class handles the displaying of the list of items and tabs. You will see later how to use this class. So, by using the correct hierarchy, we can now play with scroll events for the toolbar, due to the use of CoordinatorLayout. But if we don’t follow this hierarchy, the scroll events or UI elements might behave in a strange way.
Explanation of some properties

  • app:layout_behavior="@string/appbar_scrolling_view_behavior" Read TYL 13
  • MainActivity.java (intermediary code)

    package com.example.navigationviewtabs;
    
    import android.os.Bundle;
    import android.support.v4.view.GravityCompat;
    import android.support.v4.widget.DrawerLayout;
    import android.support.v7.app.ActionBarDrawerToggle;
    import android.support.v7.app.AppCompatActivity;
    import android.support.v7.widget.Toolbar;
    
    public class MainActivity extends AppCompatActivity {
    
        private DrawerLayout mDrawerLayout;
        private ActionBarDrawerToggle mActionBarDrawerToggle;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
            setSupportActionBar(toolbar);
    
            mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
            // Code here will be triggered once the drawer closes as we don't want anything to happen so we leave this blank
            mActionBarDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                    toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    
            //calling sync state is necessary or else your hamburger icon wont show up
            mActionBarDrawerToggle.syncState();
        }
    
        @Override
        public void onBackPressed() {
            if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
                mDrawerLayout.closeDrawer(GravityCompat.START);
            } else {
                super.onBackPressed();
            }
        }
    }

    At this point, you can run the app to see how the NavigationView looks like and how it behaves on different Android versions (pre-Lollipop and from Lollipop and above).

Next, we will proceed to part 2 of this tutorial: on setting up the tabs.

Part 2: Setup Tabs

Summary

  • setup xml file with ViewPager for the container view
  • setup xml file with RecyclerView for a page from ViewPager
  • setup xml file with a title TextView for RecyclerView rows
  • create a new Java class for RecyclerView’s adapter
  • create a new Fragment for ViewPager’s pages
  • create a new Fragment which represents the container. From here we will create the tabs and handle ViewPager’s adapter.

Project

  • fragment_container.xml

            android:padding="16dp"/>
    
    </LinearLayout>

    Note: android:background="?android:attr/selectableItemBackground" is used in order to have a click effect on the RecyclerView when its rows are clicked.
