android - Implementing FloatingGroupExpandableListView in a listview consisting 2 types of headers -

i tried implement floatinggroupexpandablelistview unable modify according custom listview.

the below code implements 2 types of headers in list.

well, implementing 2 types of header complex task me & within implementing floatinggroupexpandablelistview not easy task , not able customize code according custom listview.

please see mycustomadapter class, & please tell me how can modify achieve task ?

public class contentsfragment extends listfragment  implements ontouchlistener {  private mycustomadapter madapter; activity temp = getactivity();  string []s = new string[500]; arraylist<gs> q = new arraylist<gs>(); listview lv; int count=0;  @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate);  dbadapter db = dbadapter.getdbadapter(getactivity());  if (!db.checkdatabase())        db.createdatabase(getactivity());  db.opendatabase();  q = db.getdata();  madapter = new mycustomadapter(getactivity());  madapter.addseparatoritem(new contentwrapper(q.get(0).geta_name(),null,null));//1st type of seperator madapter.additem(new contentwrapper(q.get(0).getas_name(), q.get(0).getdesc_art(),null));   (int = 1; <= 14; i++) { if (!(q.get(i).geta_name().trim().equals(q.get(i-1).geta_name().trim()))) {    madapter.addseparatoritem(new contentwrapper(q.get(i).geta_name(), null,null));//2nd type of separator } if(!(q.get(i).getextra()==null))   madapter.addgrayseparatoritem(new contentwrapper(q.get(i).getextra(),null,null));  madapter.additem(new contentwrapper(q.get(i).getas_name(), q.get(i).getdesc_art(),null)); }  (int = 15; < 236; i++) {   if (!(q.get(i).geta_name().trim().equals(q.get(i-1).geta_name().trim()))) {        madapter.addseparatoritem(new contentwrapper(q.get(i).geta_name(), null,null));    }   if(!(q.get(i).getextra()==null))       madapter.addgrayseparatoritem(new contentwrapper(q.get(i).getextra(),null,null));     madapter.additem(new contentwrapper(q.get(i).getas_name(), q.get(i).getdesc_art(),null));      } //adapter class private class mycustomadapter extends baseadapter {  private static final int type_item = 0; private static final int type_separator = 1; private static final int type_gray_separator = 2; private static final int type_max_count = type_gray_separator + 1;  private treeset<integer> mgrayseparatorsset = new treeset<integer>();  private arraylist<contentwrapper> mdata = new arraylist<contentwrapper>(); private layoutinflater minflater;  private treeset<integer> mseparatorsset = new treeset<integer>();  public mycustomadapter(context context) {     minflater = layoutinflater.from(context);  }  public void additem(contentwrapper value) {     mdata.add(value);     notifydatasetchanged(); }  public void addseparatoritem(contentwrapper value) {     mdata.add(value);     // save separator position     mseparatorsset.add(mdata.size() - 1);     notifydatasetchanged(); }  public void addgrayseparatoritem(contentwrapper value) {     mdata.add(value);     // save separator position     mgrayseparatorsset.add(mdata.size() - 1);     notifydatasetchanged(); }      public contentwrapper getitem(int position) {     return mdata.get(position); } @override public int getitemviewtype(int position) {     int viewtype = type_item;     if(mseparatorsset.contains(position))        viewtype = type_separator;     else if(mgrayseparatorsset.contains(position)) {        viewtype = type_gray_separator;      }      return viewtype;     // return mseparatorsset.contains(position) ?

as can see there 2 types of headers(1 of black color & 1 of gray color) wit child of white color.

black background, gray background & white background sh'd child view of green background(it floatinggroupexpandableheader)(relative layout id sample_activity_list_group_item_background)! views 1-30 of part 1 , green background text part 1 (floatinggroupexpandableheader) childs 1 30 irrespective of fact weather black background, gray background, or white background ! @ view 31 want add floatinggroupexpandableheader text part 2 (child views 31-60), hope trying achieve clear !

for floatinggroupexpandablelistview xml files ready,i don't want add header or footer,

sample_activity_list_group_item.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" >    <relativelayout     android:id="@+id/sample_activity_list_group_item_background"     android:layout_width="0dp"     android:layout_height="40dp"     android:layout_gravity="center_vertical"     android:layout_weight="1"     android:background="#ffa2c955"     android:orientation="horizontal" >      <textview         android:id="@+id/sample_activity_list_group_item_text"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentleft="true"         android:layout_centervertical="true"         android:layout_marginleft="20dp"         android:textcolor="#ffffffff"         android:textsize="20sp" />      <imageview         android:id="@+id/sample_activity_list_group_expanded_image"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentright="true"         android:layout_centervertical="true"         android:layout_marginright="20dp" /> </relativelayout>  </linearlayout> 

sample_activity.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ffededed" android:orientation="vertical" >  <com.diegocarloslima.fgelv.lib.floatinggroupexpandablelistview     android:id="@+id/sample_activity_list"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:cachecolorhint="@android:color/transparent"     android:childdivider="#ff000000"     android:divider="#ff000000"     android:dividerheight="1dp"     android:paddingleft="10dp"     android:paddingtop="10dp" />  </linearlayout> 

now should add/modify in class?

please me,

thanks in advance.

try floatinggroupexpandablelistview

i find best implementation. use reflection job. need use android groupexpandablelistview , baseexpandablelistadapter.

list<contentwrapper> items = new arraylist<contentwrapper>(); contentwrapper group; (int = 1; <= 14; i++) {   if (!(q.get(i).geta_name().trim().equals(q.get(i-1).geta_name().trim()))) {     group = new contentwrapper(q.get(i).geta_name(), null,null));   }   contentwrapper item = new contentwrapper(q.get(i).getas_name(), q.get(i).getdesc_art(),null);   if(!(q.get(i).getextra()==null))      item.setshowgrayseparator();//the gray separator should merged item view;   items.add(item); } madapter.addgroup(group,items);

public class customexpandablelistadapter extends baseexpandablelistadapter {      private list<contentwrapper> mgroups = new arraylist<contentwrapper>();     private list<list<contentwrapper>> mdata = new arraylist<list<contentwrapper>>();      public void addgroup(contentwrapper group,list<contentwrapper> items) {         mgroups.add(group);         mdata.add(items);     }      @override     public int getgroupcount() {         // sticky header count         return mgroups.size();     }      @override     public int getchildrencount(int groupposition) {         // child count each group @ 'groupposition'         mdata.get(groupposition).size();     }              @override     public view getgroupview(int groupposition, boolean isexpanded, view convertview, viewgroup parent) {         //sticky header view @ 'groupposition'         contentwrapper header = mgroups.get(groupposition);         //show group view      }      @override     public view getchildview(int groupposition, int childposition, boolean islastchild, view convertview, viewgroup parent) {        //child view @ 'childposition' 'groupposition'        contentwrapper item = mdata.get(groupposition).get(childposition);        // show item view     }  }
