android - makeSceneTransitionAnimation when opening an activity from an intent from a button within a fragment -

i opening activity screen on-click of fragment button. trying make button move fragment screen activity screen via makescenetransitionanimation. not animating . how can open activity intent fragment , have animation going. appreciate help.

public class listfragment extends fragment {      floatingactionbutton fab;     @nullable     @override     public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {                  r.layout.fragment, container, false);     }        @override     public void onactivitycreated(@nullable bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);    fab.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view view) {                  intent = new intent(getactivity(), mainactivity.class);              i.putextra("title",  "title");                  activityoptionscompat options = activityoptionscompat.makescenetransitionanimation(getactivity(), fab, "image");                 activitycompat.startactivity(getactivity(), i, options.tobundle());      } }); } 

if see documentation:

/**  * create activityoptions transition between activities using cross-activity scene  * animations. method carries position of multiple shared elements started  * activity. position of first element in sharedelements  * used epicenter exit transition. position of associated  * shared element in launched activity epicenter of entering transition.  *  * <p>this requires {@link android.view.window#feature_content_transitions}  * enabled on calling activity cause exit transition. same must in  * called activity entering transition.</p>  * @param activity activity window contains shared elements.  * @param sharedelements names of shared elements transfer called  *                       activity , associated views. views must each have  *                       unique shared element name.  * @return returns new activityoptions object can use  *         supply these options options bundle when starting activity.  */ public static activityoptionscompat makescenetransitionanimation(activity activity,         pair<view, string>... sharedelements) { 

so have do

activityoptionscompat options = activityoptionscompat.makescenetransitionanimation(getactivity(), new pair<>(fav, "image")); activitycompat.startactivity(getactivity(), i, options.tobundle());
