with layout :-

my second row looks fine, first 1 looks weird. iam using recyclerview.
how can make first row second one?

try 0dp width relativelayout , whenever have used weight properties layout or views have set width or height 0dp on respective of parent layout orientation if parent layout horizontal set width 0dp or if parent layout vertical set height 0dp.

you not required given weightsum 100 layout or view default considering weightsum 100.
