Nested scrolling++ This CL adds a number of overloads for the support implementation of the nested scrolling APIs, to add the 'type' parameter. This allow developers to differentiate between direct touch scrolls, and other non-direct scrolls. Primarily this is to support dispatching the nested scrolling APIs from when a scrolling view settles from a fling. NestedScrollView and RecyclerView have both been updated to dispatch these events from a fling settle. AppBarLayout has also been updated to consume these new events. The way the interfaces have been implemented allow us to be API compatible without breaking anyone. Yes, the names are fugly but so be it. If developers wish to support the new APIs they just need to change the interface they implement. This CL also fixes some scroll issues in NSV and RV: - NSV: fling not starting if scroll is completely consumed (since it doesn't think it is dragging). - RV: intercept setting the wrong X/Y start values sometimes causing flinging in the wrong direction. BUG: 22780822 Test: included for RV Change-Id: I37de005e4fb33b5b443852058f3e1ab22ef98e20
We are not currently accepting new modules, features, or behavior changes.
NOTE: You will need to use Linux or Mac OS. Building under Windows is not currently supported.
Follow the “Downloading the Source” guide to install and set up repo tool, but instead of running the listed repo commands to initialize the repository, run the folowing:
repo init -u https://android.googlesource.com/platform/manifest -b ub-supportlib-master
Now your repository is set to pull only what you need for building and running support library. Download the code (and grab a coffee while we pull down 7GB):
repo sync -j8 -c
You will use this command to sync your checkout in the future - it’s similar to git fetch
Open path/to/checkout/frameworks/support/ in Android Studio. Now you're ready edit, run, and test!
If you get “Unregistered VCS root detected” click “Add root” to enable git integration for Android Studio.
If you see any warnings (red underlines) run Build > Clean Project.
You can do most of your work from Android Studio, however you can also build the full support library from command line:
cd path/to/checkout/frameworks/support/ ./gradlew createArchive
Run FooBarTestRun android.support.foobarSupport library has a set of Android applications that exercise support library code. These applications can be useful when you want to debug a real running application, or reproduce a problem interactively, before writing test code.
These applications are named support-*-demos (e.g. support-4v-demos or support-leanback-demos. You can run them by clicking Run > Run ... and choosing the desired application.
cd path/to/checkout/frameworks/support/ repo start my_branch_name . (make needed modifications) git commit -a repo upload --current-branch .
If you see the following prompt, choose always:
Run hook scripts from https://android.googlesource.com/platform/manifest (yes/always/NO)?
