setMaxRowHeight, IMAGES, index

[sagarpatel288]

can not resolve setMaxRowHeight and index. I am using in fragment.

[sagarpatel288]

Tried to solve by invalidate cache and restart! But it is still there!

I'm not understanding the problem. setMaxRowHeight(int) isn't working for you? What is the current behaviour? How/where are you calling it? A code snippet and/or screenshot may also help.

I think what he says is that he the IDE cannot resolve setMaxRowHeight. Probably can't import the necessary classes.

Please post some code in order to help or tell us what you did.

Below is the line where android studio cannot resolve that method:

layoutManager.setMaxRowHeight(true);

Below is the complete fragment. I have included import class as well. At layout manager, where i tried to set its Maximum row height using layoutmanager.setMaxRowHeight, android studio says it cannot resolve that method. Also consider that i am completely new in programming, coding, android developement so there are chances that i've screwed up or messed up with things!
