i worked on fragments in android, , when navigating 1 fragment fragment using replace(),addtobackstack(null). if utilize replace() without addtobackstack(null), next fragment ui overlapped current fragment ui. why happened? gone through plenty of stack overflow questions failed reason why happened.

i have written next code

accountsettingsbtn.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { fragment fragment = new accountsettingsfragment(); fragmentmanager fragmentmanager = getactivity().getsupportfragmentmanager(); fragmenttransaction fragmenttransaction = fragmentmanager.begintransaction(); // ((homescreenactivity)getactivity()).addfragmenttolist(fragment); fragmenttransaction.replace(r.id.home_frame, fragment); fragmenttransaction.addtobackstack(null); fragmenttransaction.commit(); } });
