I have an activity where I am showing single fragment at a time, total there are three different fragments.
FirstFragment and SecondFragment containing RecyclerView and ThirdFragment have a ScrollView.
The issue is when a fragment get attached in runtime, UI freezes, but custom OnItemClickListener listener works fine. When I select any list item of FirstFragment it redirect to SecondFragment, which is another list view. SecondFragment also get freeze. But if I go back using back button, FirstFragment works smooth. Similarly when I select SecondFragment list item I get redirect to last i.e ThirdFragment which is a scroll view which also get freeze and if I come back to SecondFragment it starts working smoothly, but If I go back to the FirstFragment and select any list item again and come to SecondFragment again UI freezes.
NOTE: This issue is only appearing on OS version 5.0 (lollipop and above) on 4.2.2 Jelly Bean everything is working good. There is same freezing issue with support library's TextInputLayout animation on android OS version 5.0 but works good on 4.2.2 Jelly Bean
I have created a Gist of activity, three respective fragments, RecyclerView.Adapter and custom OnItemClickListener
ProductActivity.java, ProductCategoryFragment.java, ProductListFragment.java, ProductDetailFragment.java, ItemClickSupport.java
Any help would be appreciated. Thanks

The issue is resolved. It was because I mentioned android:hardwareAccelerated="false" in AndroidManifest.xml file.
