Click listeners can be 18 | defined when [ViewHolder][4] views are instantiated. [RecyclerView][1] is 19 | available in the v7 Support Library, thus compatible with API level 7 and above. 20 | 21 | Tap "Show Log" menu item to display log of elements as they are laid out and 22 | tapped. Use radio buttons to toggle between [LinearLayoutManager][2] and 23 | [GridLayoutManager][3]. 24 | 25 | [1]: https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html 26 | [2]: https://developer.android.com/reference/android/support/v7/widget/LinearLayoutManager.html 27 | [3]: https://developer.android.com/reference/android/support/v7/widget/GridLayoutManager.html 28 | [4]: https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder.html 29 | 30 | Pre-requisites 31 | -------------- 32 | 33 | - Android SDK 27 34 | - Android Gradle Plugin 3.0 35 | - Android Support Repository 36 | 37 | Screenshots 38 | ------------- 39 | 40 | Screenshot Screenshot 41 | 42 | Getting Started 43 | --------------- 44 | 45 | This sample uses the Gradle build system.
