The navigation drawer is a panel that displays the app’s main navigation options on the left edge of the screen. It is hidden most of the time, but is revealed when the user swipes a finger from the left edge of the screen or, while at the top level of the app, the user touches the app icon in the action bar.
This lesson describes how to implement a navigation drawer using the DrawerLayout APIs available in the Support Library. Navigation Drawer Design Before you decide to use a navigation drawer in your app, you should understand the use cases and design principles defined in the Navigation Drawer design guide. Create a Drawer Layout To add a navigation drawer, declare your user interface with a DrawerLayout object as the root view of your layout. For example, the following layout uses a DrawerLayout with two child views: a FrameLayout to contain the main content (populated by a Fragment at runtime), and a ListView for the navigation drawer. Initialize the Drawer List. Fragment. The Fragment class can be used many ways to achieve a wide variety of results. In its core, it represents a particular operation or interface that is running within a larger Activity. A Fragment is closely tied to the Activity it is in, and can not be used apart from one.
Though Fragment defines its own lifecycle, that lifecycle is dependent on its activity: if the activity is stopped, no fragments inside of it can be started; when the activity is destroyed, all fragments will be destroyed. All subclasses of Fragment must include a public empty constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the empty constructor is not available, a runtime exception will occur in some cases during state restore. Topics covered here: Developer Guides For more information about using fragments, read the Fragments developer guide.

Navigation Drawer. Developer Docs Creating a Navigation Drawer The navigation drawer is a panel that transitions in from the left edge of the screen and displays the app’s main navigation options. Displaying the navigation drawer The user can bring the navigation drawer onto the screen by swiping from the left edge of the screen or by touching the application icon on the action bar. As the navigation drawer expands, it overlays the content but not the action bar.
When the drawer is fully extended, the action bar adjusts its content by replacing the current action bar title with the app name and removing all actions that are contextual to the view underneath the navigation drawer. The user can open the drawer panel by touching the navigation drawer indicator. Because they are transient, navigation drawers make views less cluttered. Open the drawer from anywhere in your app by swiping from the left edge of the screen. Dismissing the navigation drawer When to Use the Navigation Drawer More than 3 top-level views. Fragments. A Fragment represents a behavior or a portion of user interface in an Activity. You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a "sub activity" that you can reuse in different activities).
A fragment must always be embedded in an activity and the fragment's lifecycle is directly affected by the host activity's lifecycle. For example, when the activity is paused, so are all fragments in it, and when the activity is destroyed, so are all fragments. However, while an activity is running (it is in the resumed lifecycle state), you can manipulate each fragment independently, such as add or remove them. Design Philosophy You should design each fragment as a modular and reusable activity component. Figure 1. Figure 2. Fragment in Android: Tutorial with Example using WebView | Surviving w/ Android. In this post we want to explain how to use fragment in Android with a real example.
In the last post we talked about Fragment in Android and how we can use it to support multiple screen. We described their lifecycle and how we can use it. In this post we want to go deeper and create an example that helps us to understand better how we can use fragments. As example we want to create a simple application that is built by two fragments:one that shows a list of links andanother one that show the web page in a WebView. We can suppose we have two different layouts one for portrait mode and one for landscape. In the landscape mode we want something like the image below: while, in the portrait mode we want something like: The first step we have to do is creating our layout. This one is for the portrait mode and as we notice we have only one fragment containing just the link list.
For the landscape mode we have something very similar plus the FrameLayout component in the same layout. Navigation Drawer Android Example | JavatechIG.com. The navigation drawer is a panel that displays the app’s main navigation commands on the left side of the screen. It is not visible by default, and can be shown while user swipes right or while clicking on the open menu icon in the ActionBar. This example describes How to implement a navigation drawer using Support Library the DrawerLayout API. Navigation drawer is an overlay panel, that is replaced with the legacy application dashboard screen or menu. Now we don’t need to create a dedicated activity for showing all application options. For example, if you look at the older version of Facebook app, the dashboard screen was only the way to play around with the app. Lets say, if you are inside messages, you wont be able to get into the friends list, unless you come back to dashboard.
The latest version of Facebook App is using the Navigation Drawer. More information on design guidelines follow here. 3.1.
