android - Change Fragment's container height dynamically -
i want change container's height (which pageviewer) fragment class on scroll event of listview.
what have tried already :-
1.layoutparams
viewgroup.layoutparams params = view1.getlayoutparams(); params.height = mcontainerheight+ math.max(a,b); view1.requestlayout(); here view1 container.
2.getting container directly fragment class(by findviewbbyid) failed, because view in different(parent) layout , couldn't views different layout.
and many more tweaks based on above implementations.
i may doing wrong, tell want achieve. container's height should increase fill empty space between actionbar , listview. when scroll container height should increase.
what's happening .
action bar moving container isnt.
i appreciate help.

you want control fragment dynamically, have use dialogfragment instead fragment.
have at: http://developer.android.com/reference/android/support/v4/app/dialogfragment.html http://developer.android.com/reference/android/app/dialogfragment.html
you can include layout paramters, control height & width dynamically.
