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.
