I have an activity with a WebView. I would like to give the possibility to the user to scroll from one WebView to another WebView (as it’s done to Android desktop):

with something in the bottom which shows which screen is actually viewed. I have think about the ScrollView but maybe something else exists which easier to use.
what you want to use is the ViewPager

To get an indicator which shows on what page the user is use:

An example how to use it is here:
