Let’s start.
Step 1: Open Visual Studio ->New Project ->Templates ->Visual C# ->Android ->Blank App.
Select Blank App and give the Project Name and Project Location.
CUSTOM ACTION BAR MENU
Step 2: Next, create options_menu.xml file. Go to Solution Explorer -> Project Name ->Resources ->values. Then, right click and go to Add->New Item. This opens a new dialog box. Select XML File and give it a name, as option_menu.xml.
Step 3: The next step is to open the Solution Explorer -> Project Name ->Resources ->values ->options_menu.xml. Click on Open Design View and then, give the following code in it.
- <?xml version="1.0" encoding="utf-8" ?>
- <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">
-
- <item android:id="@+id/action_settings" android:title="Share" showAsAction="always" />
- <item android:id="@+id/action_settings1" android:title="Bluetooth" showAsAction="always" />
- <item android:id="@+id/action_settings2" android:title="Exit" showAsAction="always" />
-
- <item android:id="@+id/action_settings3" android:title="Share" android:showAsAction="ifRoom" />
- <item android:id="@+id/action_settings4" android:title="Bluetooth" android:showAsAction="ifRoom" />
- </menu>
Step 4: Next, open Solution Explorer -> Project Name ->MainActivity.cs. Create OnCreateOptionsMenu() after Oncreate() method.
- public override bool OnCreateOptionsMenu(IMenu menu)
- {
- MenuInflater.Inflate(Resource.Menu.option_menu, menu);
- return true;
- }
POPUP MENU CREATION
Step 5: Now, create another xml file as options_popup.xml file. For this, go to Solution Explorer -> Project Name ->Resources ->values. Right click and Add ->New Item. Then, open new dialog box. Then, select XML File and give it the name as popup_menu.xml.
Step 6: Next, open the Solution Explorer -> Project Name ->Resources ->values -> popup_menu.xml. Click on Open Design View. Then, give the following code:
- <?xml version="1.0" encoding="utf-8" ?>
- <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">
- <item android:id="@+id/action_setting1" android:title="Share" showAsAction="always" />
- <item android:id="@+id/action_settings2" android:title="Bluetooth" showAsAction="always" />
- <item android:id="@+id/action_settings3" android:title="Exit" showAsAction="always" />
- </menu>
Step 7: Next step is to open the Solution Explorer -> Project Name ->Resources ->Layout ->Main.axml. Then, give the following code.
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
- <Button android:id="@+id/btnpopupmenu" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="POPUP MENU" />
- </LinearLayout>
Step 8: Now, open Solution Explorer -> Project Name -> MainActivity.cs. Then, give the following code:
- protected override void OnCreate(Bundle bundle)
- {
- base.OnCreate(bundle);
-
- SetContentView(Resource.Layout.Main);
- Button btnpopupmenu = FindViewById < Button > (Resource.Id.btnpopupmenu);
- btnpopupmenu.Click += (s, arg) =>
- {
- PopupMenu menu = new PopupMenu(this, btnpopupmenu);
- menu.Inflate(Resource.Menu.popup_menu);
- menu.Show();
- };
- }
Step 9: Press F5 or Build and Run the Application.
Finally, we have successfully created the Xamarin Android Custom Action Bar Menu and created the Popup Menu.
