![]() ![]() The standard drawer icons can be downloaded from Google. Finally you need to set the DrawerListener for your Drawer to actually listen for these events. After you have created the new Toggle you will want to implement the DrawerOpen and DrawerClosed events to update the ActionBar title and to also update the OptionsMenu. You will want to create a new “ MyActionBarDrawerToggle” in your OnCreate, which takes in the current Activity, the icon to use, and a few strings to display if the user long presses on the toggle. In the sample you will find a class called “ MyActionBarDrawerToggle.cs,” which implements all of the proper methods. ![]() Listen for Drawer Events with ActionBarDrawerToggleĮach DrawLayout has a DrawerListener which is an ActionBarDrawerToggle that is used to notify us when the Drawer is opened, closed, state changed, or had slid open. After I replace and commit the fragment, the last things to do are to set the correct checked position in the ListView, update the ActionBar with the title of the current fragments, and most importantly, close the drawer. However, if you are not using this you are free to use the standard FragmentManager. In this example I am using the SupportFragmentManager because I am going to be using a ViewPagerIndicator which takes Support v4 Fragments. Since we have registered for an ItemClick event “ DrawerListOnItemClick” we will implement this method to replace the Resource.Id.content_frame with the fragment that the user has selected based on the position. The last thing I am doing here is registering for an ItemClick event on my ListView to detect when the user selects a section. In this sample, I am simply creating an array of sections that my application might have, however you can customize your ListView to have a custom adapter that will display images or other information. In this example we will just use a standard list, but you could completely customize it with headers, footers, or change it to something completely different. After that, you then have a “ListView” which is your actual Navigation Drawer. This is the standard layout that Google recommends, which is a “ DrawerLayout” as the root object with a “ FrameLayout” to contain your main content or fragments that you will swap in and out. Profile Fragment: Contains a small profile and image of the user.Friends Fragment: Contains a ViewPager with friends list.Browse Fragment: Grid of images to browse through.Home Activity: Consists of Navigation Drawer Layout. ![]() The navigation drawer is part of your main activity and is a container for all other sections, which are fragments that are swapped in and out. When designing for the Navigation Drawer, you should first think of your apps flow. Let’s write some code in Xamarin.Android! So enough background on the Navigation Drawer. The possibilities are endless really.Ĥ.) User familiarity as Google and others have already upgraded nearly all of their applications to follow this navigation scheme. Use for navigation, account selection, or a combination of both. This is unlike flyout which actually pushes your content off screen and is more jarring for your user.Īs you can see here, the user will slide or press the home button to slide out the navigation drawer, and then select which section they would like to go to next.ġ.) Now a standard control in the Support v4 library and ties directly into the Action Bar.Ģ.) Easy to implement with a Fragment first approach.ģ.) Highly customizable. The main difference is the navigation drawer slides on top of your main content and dims it out. Similar to a flyout menu made famous by Facebook, the Navigation Drawer is designed to be swiped out from the left side of you application. Dashboards, navigation lists, spinner drop downs, tabs, and fly out menus are all still prevalent and valid choices, however, Google has recently made a huge push to use their new standard Navigation Drawer control. But when i switch to different activity and return back to previous activity then on opening the drawer, signout becomes unclickable as in the content below the drawer is getting clicked instead of signout.When designing your app you have probably wondered about what type of navigation is the best to use. The issue is the signout works well initially. There is a textview too which says signout in the drawer. I am working on an app which has drawer layout with fragments. ![]()
