android - Implementing the headers as FloatingGroupExpandableListView -
i have custom listview in listfragment 3 types of headers(1st.green background, 2nd.black background, 3rd.gray background), can see in video.
i want customize greenish header, i.e on click of greenish header views(items) between next greenish header must minimized, & 1 time again clicking in greenish header views minimized should exapanded.
the same functionality floatinggroupexpandablelistview uses dummy items, in case views have customized.
i have no thought how can modify code accomplish task.
public class contentsfragment extends listfragment implements ontouchlistener { final context context = getactivity(); private mycustomadapter madapter; activity temp = getactivity(); textview tv1,tv3;

i did not reviewed code, here thought how accomplish it:
obviously cannot minimize all, list view nowadays part of views while actual amount of views minimize may much larger.
also after minimized views need minimized, cannot nowadays them empty views(height = 0), because list empty.
so solve sec problem, recommend manipulate info exclude views.
the first problem much harder solve, , need compromise how. can minimize visible views, entire list view might smaller or hall created within it. , after minimization finish update data, , reset of views supposed visible there in boom. work if have 1 or 2 views minimize, how ever not perfect idea.
the other solution forget list view, , have views in memory, think way of achieving it.
in general hard task.
