在Recyclerview中每次垂直滑動一個項目

如何在ViewPager垂直回收器視圖中一次實施一個項目輕掃。我也使用SnapHelper，但沒有得到正確的結果。請幫助我。在android編譯器中使用此依賴項： 'com.allattentionhere：autoplayvideos：0.0.9'。我的代碼如下......在Recyclerview中每次垂直滑動一個項目

And used this dependency in android compile

使「single_card」的高度和寬度匹配父級，因此recycleview將一次顯示單個項目。 –

感謝您的重播。其實我需要像viewPager一樣的效果。 – Gopinath

然後我不認爲recycleview是一種方式。您應該實現垂直viewpager，並查看垂直效果的Viewpager.pageTransform。 –

也許這將幫助你https://github.com/Dan-TD/SnappyRecyclerView，但你必須做什麼@Mayank也說。

謝謝。我解決了在v7支持庫中使用的PagerSnapHelper。 – Gopinath
