Navigation drawer with fragment in android

Fragment Navigation Drawer

In Common Navigation Paradigms cliffnotes, we discuss the various navigational structures available within Android apps. One of the most flexible is the Navigation Drawer. During the I/O Conference 2015, Google released NavigationView, which makes it far easier to create it than the previously documented instructions.

With the release of Android 5.0 Lollipop, the new material design style navigation drawer spans the full height of the screen and is displayed over the ActionBar and overlaps the translucent StatusBar . Read the material design style navigation drawer document for specs on styling your navigation drawer.

This guide explains how to setup a basic material design style drawer filled with navigation items that switch different fragments into the content area. In this way, you can define multiple fragments, and then define the list of options which will display in the drawers items list. Each item when clicked will switch the relevant fragment into the activity’s container view.

Make sure to setup the Google Design Support Library before using Google’s new NavigationView, announced as part of the Android M release. The NavigationView should be backwards compatible with all versions down to Android 2.1.

Make sure you have this Gradle dependency added to your app/build.gradle file:

Download the following icons and add them to your drawable folders by copying and pasting them into the drawable folder or using the New Image Asset dialog to create versions for each density.

If you use the New Image Asset dialog, choose a black foreground color and change the resource name.

Create a menu/drawer_view.xml file:

Note that you can set one of these elements to be default selected by using android:checked=»true» .

You can also create subheaders too and group elements together:

Next, you need to define your fragments that will be displayed within the activity. These can be any support fragments you define within your application. Make sure that all the fragments extend from androidx.fragment.app.Fragment.

In order to slide our navigation drawer over the ActionBar, we need to use the new Toolbar widget as defined in the AndroidX library. The Toolbar can be embedded into your view hierarchy which makes sure that the drawer slides over the ActionBar .

Create a new layout file res/layout/toolbar.xml with the following code:

Note that when the android:fitsSystemWindows attribute is set to true for a view, the view would be laid out as if the StatusBar and the ActionBar were present i.e. the UI on top gets padding enough to not be obscured by the navigation bar. Without this attribute, there is not enough padding factored into consideration for the ToolBar :

We want our main content view to have the navigation bar and hence android:fitsSystemWindows is set to true for the Toolbar .

To use the Toolbar as an ActionBar , you need to disable the default ActionBar . This can be done by setting the app theme in styles.xml file.

Also note that normally you should decide on your color scheme by going to Material Palette and choosing a primary and dark primary color. For this example, we will pick purple-based colors as shown in the screenshot.

Note: If you forget to disable the ActionBar in styles.xml , you are likely to see a java.lang.IllegalStateException with an error message that reads This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead. If you see this message, you need to make sure to follow the previous steps.

Next, let’s setup a basic navigation drawer based on the following layout file which has the entire drawer setup in res/layout/activity_main.xml . Note that the Toolbar is added as the first child of the main content view by adding the include tag. Note: if you are using a CoordinatorLayout, it must not lie outside of the DrawerLayout. See https://stackoverflow.com/questions/32523188/coordinatorlayout-appbarlayout-navigationdrawer

Now, let’s setup the drawer in our activity. We can also setup the menu icon too.

Setup a handler to respond to click events on the navigation elements and swap out the fragment. This can be put into the activity directly:

The NavigationView also accepts a custom attribute that can reference a layout that provides a header of our layout. For instance, you can create a layout/nav_header.xml similar to the following:

You would then reference this in the layout res/layout/activity_main.xml in the NavigationView with the app:headerLayout custom attribute:

This app:headerLayout inflates the specified layout into the header automatically. This can alternatively be done at runtime with:

If you need to get a reference to the header, you need to use the new getHeaderView() method. Note, that you have to check the header count in order to avoid NPE!

In order for the hamburger icon to animate to indicate the drawer is being opened and closed, we need to use the ActionBarDrawerToggle class.

In your res/values/strings.xml add the following:

We need to tie the DrawerLayout and Toolbar together:

Next, we need to make sure we synchronize the state whenever the screen is restored or there is a configuration change (i.e screen rotation):

We also need to change the onOptionsItemSelected() method and allow the ActionBarToggle to handle the events.

The ActionBarToggle will perform the same function done previously but adds a bit more checks and allows mouse clicks on the icon to open and close the drawer. See the source code for more context.

One thing to note is that the ActionBarDrawerToggle renders a custom DrawerArrowDrawable for you for the hamburger icon.

Also, make sure to be using androidx.appcompat.app.ActionBarDrawerToggle version.

To have the status bar translucent and have our drawer slide over it, we need to set android:windowTranslucentStatus to true. Because this style is not available for pre Kitkat devices, we’ll add res/values-v19/styles.xml file for API version 19 and onwards. Note: If you modify your res/values/styles.xml directly with this android:windowTranslucentStatus line, you are likely to need to build only for SDK versions 19 or higher, which will obviously limit you from supporting many older devices.

Note many apps and developers switched to use minSdkVersion=21. It covers

85% of Android devices worldwide as of 2019.

In res/values-v19/styles.xml we can add the following:

Now if you run your app, you should see the navigation drawer and be able to select between your fragments.

One improvement made to the design support library 23.1.0 is the addition of support for custom views for the navigation drawer items. For instance, we can create a custom switch like the navigation drawer from Google Play Movies for one of the rows:

The approach is the same as adding ActionView items to the ActionBar. We simply need to define a separate layout such as the following snippet. We will call this file action_view_switch.xml :

We then reference this layout using the app:actionLayout attribute. A title must be provided but can also be set to blank:

You can attach events directly in XML so long as your Activity will implement the method. To add an event handling to the toggle switch programmatically through Java, you will need to first get the menu instance and get access to the corresponding ActionView:

Custom widgets using app:actionViewClass can also be used too for menu items as well now too. For more details about how Action Views, see adding the SearchView to ActionBar guide.

In certain situations, especially on tablets, the navigation drawer should be a permanent fixture on the activity acting as a sidebar:

To achieve this effect, review the following links which describe one approach:

Third-party libraries may also make this easier to achieve.

There are a few third-party libraries that are still relevant as possible alternatives to using the DrawerLayout directly which provide certain material design elements automatically:

Often these are unnecessary but check them out to see the functionality they provide.

The current version of the design support library does come with its limitations. The main issue is with the system that highlights the current item in the navigation menu. The itemBackground attribute for the NavigationView does not handle the checked state of the item correctly: somehow either all items are highlighted or none of them are. This makes this attribute basically unusable for most apps.

Although many navigation drawer examples show how fragments can be used with the navigation drawer, you can also use a RelativeLayout / LinearLayout if you wish to use the drawer as an overlay to your currently displayed Activity.

Instead of you can substitute that for a

Instead of this:

You can instead use the LinearLayout container to inflate the Activity directly:
