AndroidMultilevel expandableListView, 4th level

AndroidMultilevel expandableListView, 4th level - java

I'm struggling with multilevel Expandable ListViews. I manage to make a 3 level Expandable ListView it is to say :
-- GrandParent
--- Parent
----- Child
But whenever I try to add a 4th sub child, the view seems to appear behind the last level. Here are the elements I use to achieve this :
CustomExpandableListView.java
public class CustomExpandableListView extends ExpandableListView {
public CustomExpandableListView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
public CustomExpandableListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomExpandableListView(Context context) {
super(context);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
heightMeasureSpec = MeasureSpec.makeMeasureSpec(2000, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);

try {
super.onDetachedFromWindow();
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
}
}

Problem with an ExpandableList with 3 level

I have a problem with my ExpendableList. I am trying
to make a 3 level expandablelist. The display on the 3 levels works
fine and stays tidy as it should. But I don't know why, the
subcategories are duplicated. Here is the whole code with the adapter
and the creation of my HashMap. If you have an idea where this comes
from you would help me a lot!

famille.add("famille "+g);

type.add("type " + g+h);

// TODO Auto-generated method stub
System.out.println("Name is"+name);
System.out.println("purpose is"+purpose);
}
}

In your ExpandableListAdapter class under getChildView it looks like you are telling the app to loop through all of the hints and it finishes on "Company Name"
maybe change
while(i<6)
{
switch (i)
{
case 1:editetext.setHint("Contact Person");
break;
case 2:editetext.setHint("Contact Person Photo");
break;
case 3:editetext.setHint("Designation/Job");
break;
case 4:editetext.setHint("CEO Name");
break;
case 5:editetext.setHint("Company Name");
break;
}
i++;
}
to
switch (childPosition)
{
case 1:editetext.setHint("Contact Person");
break;
case 2:editetext.setHint("Contact Person Photo");
break;
case 3:editetext.setHint("Designation/Job");
break;
case 4:editetext.setHint("CEO Name");
break;
case 5:editetext.setHint("Company Name");
break;
}

actual i have better solution why dont u simply use xml code to put hint in your edit text.It will be easy for u and it is not mendetory to code it programmatically.hope u get it

Cant see items.remove(child) on click on delete. I think you should try deleting the child from the list and than set the adapter with updated values. #Achin

How to add different image for each group in expandable Listview

In my Expandable Listview, have three groups. I want to add different three image for that group. i tried many codes, but not working.
My code:
Main Activity:
HashMap<String, List<String>> rightDrawerListDetail = getData();
List<String> rightDrawerListTitle = new ArrayList<String>(rightDrawerListDetail.keySet());
adapterR = new CustomExpandableListAdapter(this, rightDrawerListTitle,rightDrawerListDetail);
mRightDrawerList.setAdapter(adapterR);
private HashMap<String, List<String>> getData(){
HashMap<String, List<String>> expandableListDetail = new HashMap<String, List<String>>();
ArrayList<String> arrayList = mydb.getAllAddress();
List asRider = new ArrayList();
asRider.add("hello");
List asRidee = new ArrayList();
asRidee.add("hai");
List recent = new ArrayList();
recent.add("Success");
expandableListDetail.put("As a Rider",asRider);
expandableListDetail.put("As a Ridee",asRidee);
expandableListDetail.put("My Recent Activities",recent);
return expandableListDetail;
}
CustomExpandableListAdapter.java:
public class CustomExpandableListAdapter extends BaseExpandableListAdapter {
private Context mContext;
private List<String> mGroups;
private LayoutInflater mInflater;
private HashMap<String, List<String>> mexpandableListDetail;
public CustomExpandableListAdapter(Context context, List<String> groups,HashMap<String, List<String>> expandableListDetail) {

}
});*/
return convertView;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
Please anyone help to me!
Thanks in advance

In your right_drawer_group.xml add an ImageView where you want your group image to be placed, lets say groupImage.
In your getGroupView:
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.right_drawer_group, null);
}
//Set group image
ImageView groupImage = (ImageView)convertView.findViewById(R.id.groupImage);
switch((String)getGroup(groupPosition))
{
case "As a Rider":
//groupImage set correct image
break;
case "As a Ridee":
//groupImage set correct image
break;
case "My Recent Activities":
//groupImage set correct image
break;
}
// Get the group item
String listTitle = (String) getGroup(groupPosition);
// Set group name
TextView textView = (TextView) convertView.findViewById(R.id.textGroup);
textView.setText(listTitle);
ImageView indicator = (ImageView) convertView.findViewById(R.id.groupIndicator);
if (isExpanded) {
indicator.setImageResource(R.drawable.arrowup);
} else {
indicator.setImageResource(R.drawable.arrowdown);
}
return convertView;
}
It's not the most neat solution as if you change the group name this will break, but it will work for now. Better solution would be is to pass the groups as objects containing getName and getImageId.

Thanks in Advance.

your problem is here:
#Override
public int getGroupCount() {
return ParentClickStatus;
}
as you extends BaseExpandableListAdapter, getChildrenCount and getGroupCount handle number of your view and as ParentClickStatus is equal to -1 getGroupView never called
solution
you need return group row number that you have, so change your code with:
#Override
public int getGroupCount() {
return _listDataHeader.size();
}
for an example you can see section 15. Implementing an expandable ListView
UPDATE
you need change your constructor too:
public Myexpandable_ListAdapter(Context context,
List<? extends Map<String, ?>> groupData,
int expandedGroupLayout,
String[] groupFrom, int[] groupTo,
List<? extends List<? extends Map<String, ?>>> childData,
int childLayout, String[] childFrom,
int[] childTo) {
super();
// TODO Auto-generated constructor stub
}
you passed your data to here, but you don't set to any local data, for example you tried to use _listDataChild in getChild method, but you not initialize that at all, you need initialize that in constructor with your data that passed here.
