SublimeNavigationView

... is a complete rewrite of NavigationView (from Design Support library) that enables usage of Checkboxes, Switches & Badges in/as menu items. Menus are defined in good-old XML, and parsed using a custom MenuInflater. SublimeNavigationView works with Parcelable menus which means that state retention is built-in. Moreover, it can support multiple menus while preserving their respective states. Groups added to the menu have the added feature of being collapsible/expandable. Along with this, SublimeNavigationView allows a few options for custom styling.

Walkthrough

Screenshots have been taken from the sample application available here:

How the menu looks:

SublimeNavigationView can work with any number of menus. As an example of this, the sample application shows how to handle two of them:

Switching between menus:

First Menu Second Menu

SublimeMenu supports grouping of menu items. In addition to the standard features such as defining a checkable policy, ordering etc., a SublimeGroup can be expanded/collapsed - on user input, through XML definition, or programmatically:

Collapsed Expanded

XML definitions are quite straight-forward. An example:

<Text
  android:id="@+id/text_item_1"
  android:title="Independent item"
  android:hint="(Optional) hint for this item"/> 

This would translate to:

A Text item with an icon - and another, that shows icon space, but doesn't display an icon:

<Text
  android:id="@+id/text_item_2"
  android:title="Independent item with icon"
  android:icon="@drawable/archive" />  <Text
  android:id="@+id/text_item_5"
  android:title="Indented item"
  android:hint="Show icon space on-demand"
  app:showIconSpace="true"/> 

Output:

TextWithBadge menu items can be presented in two forms - initialized & uninitialized. In uninitialized form, the item will display an indeterminate ProgressBar in place of badgeText:

<TextWithBadge
  android:id="@+id/text_with_badge_item_1"
  android:title="Text with badge item"
  app:valueProvidedAsync="true"/> 

In initialized form, the item will have its badgeText set in XML:

<TextWithBadge
  android:id="@+id/text_with_badge_item_1"
  android:title="Text with badge item"
  app:badgeText="25"/> 

This feature can be used if the badgeText is being retrieved through a network call, or if some computation needs to be performed before it can be displayed. Once the text is available, you can display it using:

((SublimeTextWithBadgeMenuItem)snv.getMenu().getMenuItem(R.id.text_with_badge_item_1))

.setBadgeText("25").setValueProvidedAsync(false);
 

SublimeNavigationView also supports a few styling options. As an example, the sample application uses a custom typeface spicified in the view's xml definition:

<com.appeaser.sublimenavigationviewlibrary.SublimeNavigationView
  ....
  ....
  app:snvHeaderLayout="@layout/nav_header"
  app:snvMenu="@menu/test_nav_menu_1"
  app:snvItemTypefaceFilename="planer_bold_webfont.ttf"
  app:snvHintTypefaceFilename="planer_reg_webfont.ttf"
  app:snvSubheaderItemTypefaceFilename="planer_bold_webfont.ttf"/> 

Styling info can also be set programmatically by providing a initialized SublimeThemer.

There were some features that were left out on purpose. One of them was the option to define sub-menus. This feature is essential when used within the ActionBar design pattern, but its importance in a navigation view is lost on me.

The NavigationView from design library adds separators automatically. SublimeNavigationView takes a different approach, and lets you decide where the separators should go. So, to create a divider, add a Separator menu item:

<Separator
  android:id="@+id/separator_item_1" /> 

Since there are no space concerns, orderInCategory & menuCategory have also been left out.
