Webview inside RecyclerView is showing blank screen sometimes on Nougat devices only
webview inside recyclerview scroll
android webview zoom to fit content
load url in webview android

There are a couple of related question in SO but that didn't solve my problem. So is there a way in Android webview setting which can solve this problem? I have written detail description in the bug link.

For a start webview consumes memory because it load has to load and render html data. Rather than using a webview in a recycler view, I think it would be better if you implemented it either of these two ways:
- You handle the list of data in html and send it into the webview and remove the recycler view completely
- You draw the layout of the expected contents in xml and inflate it directly into the recyclerview and remove webview completed. (Note: you can inflate different views into a recycler depending on the adapter position and data at that position).
Using a webview might seem the easy way to implement whatever you are trying but trust me, the drawbacks outweight the benefit. So its just best to avoid it.
