안드로이드 주소록에서 보여지는 퀵액션 같은 걸 붙여보자 본문
I have updated the quickaction implementation code so it can be used more efficient and the dialog will be automatically dismissed after pressing the action item. All the source codes now available via github so you can track the changes.
Official Twitter application for Android has introduced new Android UI features and behavior patterns such as Dashboard, Search Bar, QuickAction and Action Bar. One of the interesting pattern is QuickActions that displays contextual actions in a list view. This pattern actually already exists in QuickContact dialog/bar in default Contact application (since Android 2.0).
The QuickActions dialog is not included in standard Android SDK, so we have to create it manually. At first, i had no idea on how to create it so i decided to download and read the Contact app source code from Android git. I found that the QuickContact dialog uses private API call (com.android.internal.policy.PolicyManager) that does not exists in standard SDK. After posting question about it on google groups and stack overflow, i got the solution for it from Qberticus (thanx Qberticus!).
Qberticus’s QuickActions uses simple/plain layout so i have to create a custom layout so it will look like QuickContact in Contact app or QuickActions in Twitter app. Based on QuickContact source code, i made a slight modification on Qberticus’s BetterPopupWindow class and extended it to implement custom layout. I also made it customizeable, so the icon and text in action list can be customized.
Here are the screenshoots of QuickActions demo:
