leanback: support preferring key line over edge We have a requirement that for WINDOW_ALIGN_HIG_EDGE, when there are limited items, we prefer the first item aligned to keyline instead of last item aligned to bottom padding. Introduced two APIs: setPreferKeyLineOverLowEdge and setPreferKeyLineOverHighEdge. "prefer keyline over low" is by default false. "prefer keyline over high" is by default true since keyline is before high edge and user usually prefer align to lower side. In current implementation, the scroll_max is always decided by the last item align to edge of bottom padding. When we prefer keyline over high edge, scroll max is no longer only decided by last item, it will be decided by both the last item and first item. So we will need updateScrollMin/Max altogether. The CL also clean up GridLayoutManager code, no longer need concept of mScrollOffsetPrimary. Bug: 38036352 Test: testPreferKeyLine1 testPreferKeyLine2 testPreferKeyLine10000 testScrollSecondaryCannotScroll testScrollSecondaryNeedScroll Change-Id: Ia1e03b3eb8f5d78255090380684e35e5434172bc
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 FooBarTest
Run android.support.foobar
Support 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)?
