Android detects right-sliding WebView and androidwebview

Today, the new product has to slide right .... After the right-sliding gesture is detected, the event is not processed and placed in the Activity for corresponding processing.

How does android disable webview sliding between the left and right sides?

Add android: scrollbars = "vertical" to the xml webview attribute"
