android - Recycler View with GridLayoutManager horizontal Scrolling doesnt work -
i have activity, includes fragment. fragment includes recycler view. want display data of game in grid. need scroll down (every round of game 1 row) horizontal, because need 5 - 10 columns. when id use paramter android:scrollbars="vertical|horizontal" in recycler view scrolls down , makes column small. happens when set horizontal.
code: activity

you used wrong constructor new gridlayoutmanager(getactivity(), gamedata[0].length). javadoc says "creates vertical gridlayoutmanager".
try new gridlayoutmanager(getactivity(), 1, gridlayoutmanager.horizontal, false) instead.
here 1 counts number of rows.
