How does one go about manually expanding and collapsing an expandablelistview? I know of expandGroup(), but am not sure where to set the onClickListener(), as half of this code, is in a separate library project.

Ideally, my bosses would like to have a "+" button, that when clicked expands the listview manually. Rather than clicking anywhere on the view and it doing it automatically. Is this possible? Also, setting setClickable(false) seems to have no effect. Because it'll still expand when any list item is clicked. Am I missing something there also?
Cheers.
You can add an ExpandableListView Group Click Listener ("ExpandableListView::setOnGroupClickListener") to monitor and suppress click event for the ListView Groups. Using your code example, this would be done in your "ExpandableDeliveryList" module after you create the ExpandableListView.
Then in your "+" (and "-") Button click handlers, you can add logic to expand/collapse some or all of the ListView Groups using the "ExpandableListView::expandGroup()" and "ExpandableListView::collapseGroup()" methods.
You do not need to return "false" from the overridden "isChildSelectable()" method as this has no effect on what you are trying to accomplish (and will prevent anyone from clicking/selecting child items in the ListView).
Code examples are shown below:
// CREATE THE EXPANDABLE LIST AND SET PROPERTIES //
final ExpandableListView expandList = getExpandableListView();
//...
expandList.setOnGroupClickListener(new android.widget.ExpandableListView.OnGroupClickListener() {
#Override
public boolean onGroupClick( ExpandableListView parent,
View view,
int groupPosition,
long id) {
// some code...
// return "true" to consume the event (and prevent the Group from expanding/collapsing) / "false" to allow the Group to expand/collapse normally
return true;
}
});
To manually expand and collapse the ListView Groups:
// enumerate thru the ExpandableListView Groups
// [in this code example, a single index is used...]
int groupPosition = 0;
// expand the ListView Group/s
if (m_expandableListView.isGroupExpanded(groupPosition) == false) {
// API Level 14+ allows you to animate the Group expansion...
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
m_expandableListView.expandGroup(groupPosition, true);
}
// else just expand the Group without animation
else {
m_expandableListView.expandGroup(groupPosition);
}
}
// collapse the ListView Group/s
else {
m_expandableListView.collapseGroup(groupPosition);
}
Hope this Helps.

I expect to handle it without event like setOnChildClickListener, setOnGroupExpandListener,setOnGroupCollapseListener, etc. Thanks for help
change getGroupView to:
#Override
public View getGroupView(int headPosition, boolean is_expanded, View view, ViewGroup headGroup) {
// Heading of each group
String heading = (String) getGroup(headPosition);
if (view==null){
view = layoutInflater.inflate(R.layout.list_header,null);
}
TextView headerTv = view.findViewById(R.id.headerTv);
headerTv.setText(heading+"");
boolean hasSelected = false;
ArrayList<ChildDataModel> childs =
childData.get(headerData.getItemAtIndex(headPosition));
for(int i=0;i<childs.size();i++){
if(childs.get(i).isSelected){
hasSelected = true;
}}
if(hasSelected)
headerTv.setBackgroundColor( Color.BLUE );
else
headerTv.setBackgroundColor( Color.RED);
return view;
}
you most highlight the header view when getGroupView executed if childs highl sign selected chileds and if selected eny then highlight header
Thank you #hunixa siuri It does work well. However Code must be edited a little as below
#Override
public View getGroupView(int headPosition, boolean is_expanded, View view, ViewGroup headGroup) {
// Heading of each group
String heading = (String) getGroup(headPosition);
if (view==null){
view = layoutInflater.inflate(R.layout.list_header,null);
}
TextView headerTv = view.findViewById(R.id.headerTv);
headerTv.setText(heading+"");
boolean hasSelected = false;
ArrayList<ChildDataModel> childs = childData.get(headerData.get(headPosition));
for(int i=0;i<childs.size();i++){
if(childs.get(i).getTitle().equalsIgnoreCase( "China" )){
hasSelected = true;
}}
if(hasSelected)
view.setBackgroundColor( Color.BLUE );
else
view.setBackgroundColor( Color.RED);
return view;
}

}
the above code for displaying dashboard fragment list.
https://postimg.org/image/nqvp1dud9/ - This link is FilterScreen
By using this image if i filter the job based on the designed UI detail. That should replace into the DashboadFragment list The result should display into the DashBoard Fragment. How can I add pagination on Filter screen the same which have in DashBoardFragment.

I am trying to get values of child view for save it in database, before i need check each field by type for valid data.
Currently i am checking the values in adapter and works well. Possibly not the right way...
But how to get value of each view by type only clicking save button in FragmentActivity in action bar??
I am trying onChildClick but click event by editText not working. Thanks!
SOLVED
Now I have resolved, but I think is not the right way for do it.
In model class Child i created new field with View.
private View view;
and assigned complete View by type (editText,TextView, etc) in adapter getChildView for example:
child.setView(holder.editText);
and finally use in FragmentActivity
private void checkParameters() {
boolean validated = true;
int groupCount = expandList.getExpandableListAdapter().getGroupCount();
for (int i = 0; i < groupCount; i++) {
int childCount = expandList.getExpandableListAdapter().getChildrenCount(i);
for (int j = 0; j < childCount; j++) {
Child child = (Child) expandList.getExpandableListAdapter().getChild(i, j);
//secure check
if (child.getView() != null) {
int itemType = child.getType();
//only editText
if (itemType >= 1 && itemType <= 7) {
EditText ed = (EditText) child.getView();
//do something
}
}
}
}
}
Anyone know how to do this more efficiently???
I have an ExpandableListView on a fragment and when I choose an item I am changing the background and text colour of this item (TextView). This works fine. However when I collapse the group which contains the currently selected item, the selection is lost. How can I stop this from happening/set the selected item back to what it should be?
I have tried messing around with the onGroupExpand/CollapseListener's but not had any success. For example I have tried this:
_list.setOnGroupExpandListener(new OnGroupExpandListener() {
#Override
public void onGroupExpand(int groupPosition) {
_list.setItemChecked(_activePosition, true);
}
});
Note: _list and _activePosition are declared at class level.
Here is my code for setting the checked item, from the examples I've seen I think this is standard practice, but please advise if not as I'm new to android.
HelpItemsFragment.java
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final List<HelpCategory> itemList = new ArrayList<HelpCategory>();
HelpCategory helpCategory;
//replace this with database stuff later
helpCategory = new HelpCategory();
helpCategory.setTitle("Group 1");
helpCategory.addHelpItem(new HelpItem((long) 1, "1.1", "Details for 1.1"));
helpCategory.addHelpItem(new HelpItem((long) 1, "1.2", "Details for 1.2"));
helpCategory.addHelpItem(new HelpItem((long) 1, "1.3", "Details for 1.3"));
itemList.add(helpCategory);
helpCategory = new HelpCategory();
helpCategory.setTitle("Group 2");
helpCategory.addHelpItem(new HelpItem((long) 2, "2.1", "Details for 2.1"));
helpCategory.addHelpItem(new HelpItem((long) 2, "2.2", "Details for 2.2"));
helpCategory.addHelpItem(new HelpItem((long) 2, "2.3", "Details for 2.3"));
itemList.add(helpCategory);
HelpExpandableListAdapter listAdapter = new HelpExpandableListAdapter(this.getActivity(), itemList);
_list.setAdapter(listAdapter);
_list.setOnChildClickListener(new OnChildClickListener() {
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
int index = parent.getFlatListPosition(ExpandableListView.getPackedPositionForChild(groupPosition, childPosition));
HelpItem helpItem = itemList.get(groupPosition).getHelpItemList().get(childPosition);
_activePosition = index;
_callback.onItemSelected(null, helpItem.getTitle(), helpItem.getDetail(), _activePosition);
parent.setItemChecked(index, true);
return true;
}
});
Adapter class HelpExpandableListAdapter should be like
public class HelpExpandableListAdapter extends BaseExpandableListAdapter {

mParent = parent;

}

I use https://github.com/bulletnoid/StaggeredGridView this library for make a pinterest style layout and use pulltorefresh on this layout. Also ı have a slide menu for choose different category and according to category which is user choose, refresh and refill the staggred again.
Pulltorefresh is work fine.
if user top of the layout and choose a category on slide menu it's work correctly. But if user bottom of the layout and choose a category on slide menu it's work not correctly .
the scenario, top of layout and select category on slidemenu and refill staggered layout. it's work correctly
the scenario, bottom of layout and select category on slidemenu and refill staggered layout. it's not work correctly

I guess i had a same problem with using the same pinterest style library with you. i solve my problem by put this
#Override
public void onResume() {
// TODO Auto-generated method stub
super.onResume();
mAdapter = new SearchSTGVAdapter(getActivity(), adsList, (Fragment)this);
ptrstgv.setAdapter(mAdapter);
}
which previously I put it in the onCreate method
For your information, I am implement this pinterest style in a view pager not a sliding menu
