Actions on List / Grid collection
Actions on a data item of list view or grid view
Notes/Observations:
-
Display prominent actions directly on list view items using drop-downs
-
This lets people invoke actions on data without having to navigate all the way down the hierarchy.
-
This could have been handled by navigating the user to next screen and then take the action. We avoided that step by following this pattern.
Status Bar Notification – Expanding Notification Message
In Jelly Bean we can show the first few lines of a message or show a larger image preview. This provides the user with additional context, and – in some cases – may allow the user to read a message in its entirety. The user can pinch-zoom or two-finger glide in order to toggle between base and expanded layouts. For single event notifications, Android provides two expanded layout templates (text and image) to re-use in the application.
Status Bar Notification with Actions
Starting with Jelly Bean, Android supports optional actions that are displayed at the bottom of the notification. With actions, users can handle the most common tasks for a particular notification from within the notification shade without having to open the originating application. This speeds up interaction and, in conjunction with “swipe-to-dismiss”, helps users to streamline their notification triaging experience.
Status Bar Notification – Stack Messages
You can provide more detail about the individual notifications that make up a stack by using the expanded digest layout. This allows users to gain a better sense of which notifications are pending and if they are interesting enough to be read in detail within the associated app.
Swipe Navigation – Content Detail View
If your users are likely to want to look at multiple items in sequence, allow them to navigate between items from within the detail view. Use swipe views.
Swipe left and right to switch between Emails.
Thumbnail Control Navigation – Content Detail View
In addition to supporting swipe gestures to move left or right through pages, Magazines provides a thumbnail view control that lets people quickly jump to specific pages.
Contextual Menu in Action Bar on Single and Multiple Data
Actions that apply to a single selected data item don’t necessarily apply to multiple selected data items of the same kind.
Contextual Menu in Action Bar
CAB is a temporary action bar that overlays your app’s current action bar while data is selected. It appears after the user long presses on a selectable data item.
Confirmation – Prompt User
