I want to show the count and all the data when clicked. But so far in testing using click on the Parent item
I tried increment checkedCount when check. But it show only checked count in in one group child elemements.

Someone please let me know why Toast is not showing on clicking child element.Any help would be appreciated.
THANKS
Change your adapter code from this..
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;
}
to this..
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
Hope this helps.
On each row i have two EditTexts.when i change the first one , i want the other to be changed as well(if needed ,for now just setting there '25' for testing).I am using a viewholder pattern,and setting on each of the first edittexts a TextChangedListener,expecting the second to be changed as well .problem is , whenever i change ANY of the first edittexts on ANY of the rows ,only the edittext on the last row is changed. here is the code of the adapter(listener is in getgroupview):
public class CustomExpandableListAdapterNewWorkout extends BaseExpandableListAdapter {

probably there is something basic i don't understand about adapters and viewholders, and i would like to know the correct method to address it.
ok my bad.
should have declared "GroupViewHolder groupViewHolder" inside the getGroupView method,this way a new one with a new listener is created each time and affects his corresponding row
Good day!
I'm a newbie at android/java programming and I'm trying to create, kinda like, a history function to my app. I'm using an expandableListView with a gridView (or listView; I don't really know what else to use aside from these two) inside to show said history. All the data comes from sqLite database which has 3 tables named Requests, Properties & ReqLine all linked together.
The format I'm trying to create is something like this (Sorry, cant post images yet):
HEADER: TextView ----- data from db 1st table
CHILD: TextView ----- data from 2nd GRID: 1)item from DB 3rd table 2)item
from DB 3rd table
I was able to populate the header and child portions but I'm having trouble with the child gridView repeating data on every child. I know it's with the way I'm passing the ArrayList to the GridView Adapter but I don't the correct way of doing it or how to implement it.
I tried a bunch of ways including adding another arraylist to my header class model but I don't know how I should get the childcount for it in my adapter.
I've seen lots on posts here in SO but none of them seems to have the solution to my problem. Can anyone help me with this? Thanks in advance! Suggestions on revisions are welcome as well.
Here's my code for the history fragment:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.history_tab_layout, container, false);
openHelper = new DatabaseHelper(getActivity());
myDb = openHelper.getReadableDatabase();
TextView _number = (TextView) rootView.findViewById(R.id.lblNumber);
TextView _date = (TextView) rootView.findViewById(R.id.lblHistoryDate);
TextView _transtype = (TextView) rootView.findViewById(R.id.lblHistoryTransType);
TextView _amount = (TextView) rootView.findViewById(R.id.lblHistoryAmount);
Cursor mCursor = null;
Cursor dataCursor = null;
Cursor itemCursor = null;
String Query = "SELECT * FROM Requests";
mCursor = myDb.rawQuery(Query, null);
transHistory = new ArrayList<HistoryHeader>();
gridHistory = new ArrayList<GridItems>();
int count = 1;
if(mCursor.getCount()!=0) {
while (mCursor.moveToNext()) {
String reqDate = mCursor.getString(mCursor.getColumnIndex("RequestDate"));
String reqTransType = mCursor.getString(mCursor.getColumnIndex("TransType"));
String reqTotalAmt = mCursor.getString(mCursor.getColumnIndex("AmtTotal"));
String reqPCode = mCursor.getString(mCursor.getColumnIndex("Property"));
String BaseId = mCursor.getString(0);
HistoryHeader history = new HistoryHeader(count, reqDate, reqTransType, reqTotalAmt);
String Query2 = "SELECT * FROM Projects WHERE PrjCode = '"+ mCursor.getString(3) +"'";
dataCursor = myDb.rawQuery(Query2, null);
if (dataCursor.getCount()!=0){
while (dataCursor.moveToNext()){
String reqPName = dataCursor.getString(dataCursor.getColumnIndex("PrjName"));
history.setItemList(createItems(reqPCode, reqPName, 1));
}
}
String Query3 = "SELECT * FROM ReqLine WHERE Base_Id = "+ BaseId;
itemCursor = myDb.rawQuery(Query3, null);
if (itemCursor.getCount()!=0) {
while (itemCursor.moveToNext()) {
String reqPurpose = itemCursor.getString(itemCursor.getColumnIndex("Purpose"));
String reqAmount = itemCursor.getString(itemCursor.getColumnIndex("AmtLine"));
Integer reqNum = itemCursor.getInt(itemCursor.getColumnIndex("Linenum"));
GridItems test = new GridItems(reqNum, reqPurpose, reqAmount);
gridHistory.add(test);
}
}
transHistory.add(history);
count++;
}
}
final ExpandableListView _Content = (ExpandableListView) rootView.findViewById(R.id.historyList);
_Content.setIndicatorBounds(5,5);
HistoryAdapter exAdpt = new HistoryAdapter(getActivity(), transHistory, gridHistory);
_Content.setIndicatorBounds(0,20);
_Content.setAdapter(exAdpt);
return rootView;
}
private List<HistoryDetail> createItems(String _strPropertyCode, String _strPropertyName, int num) {
List<HistoryDetail> result = new ArrayList<HistoryDetail>();
for (int i=0; i < num; i++) {
HistoryDetail item = new HistoryDetail(i, _strPropertyCode, _strPropertyName);
result.add(item);
}
return result;
}
And the Code for my HistoryAdapter.java
public class HistoryAdapter extends BaseExpandableListAdapter {
private Context context;
private List<HistoryHeader> _listDataHeader;
private ArrayList<GridItems> _listGridItems;
public HistoryAdapter(Context context, List<HistoryHeader> _listDataHeader, ArrayList<GridItems> _listGridItems) {

#Override

Hope that helps!
if (v.getId() == R.id.contact_btnNext) {
StringBuilder id = new StringBuilder();
String prefix = "";
for (Datamodel datamodel : mAdapter.arrSelectedModel ) {
id.append(prefix).append(datamodel.getId());
prefix = ",";
}
Using this code I am getting value of all ListView it's which is checked and unchecked in id:
public class AdapterContactAddfriend extends BaseAdapter {
private Context context;
private ArrayList<Datamodel> arrModel;
public ArrayList<Datamodel> arrSelectedModel;
public ArrayList<Boolean> arrCheckboxState;
ViewHolder holder;
ImageLoader imageloader;
public AdapterContactAddfriend(Context context,
ArrayList<Datamodel> arrModel) {
this.context = context;
this.arrModel = arrModel;
arrCheckboxState = new ArrayList<Boolean>();
arrSelectedModel = new ArrayList<Datamodel>();
imageloader = new ImageLoader(context);
for (int i = 0; i < arrModel.size(); i++) {
arrCheckboxState.add(false);
}
}
#Override
public int getCount() {
return arrModel.size();
}
#Override
public Object getItem(int position) {
return arrModel.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder = new ViewHolder();
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater
.inflate(R.layout.row_contactaddfriend, null);
holder.checkBox = (CheckBox) convertView
.findViewById(R.id.rowcontact_checkbox);
convertView.setTag(holder);
} else
holder = (ViewHolder) convertView.getTag();
holder.txtContactName.setText(arrModel.get(position).contactName);
holder.checkBox
.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
int position = (Integer) buttonView.getTag();
if (isChecked) {
arrCheckboxState.set(position, true);
arrModel.get(position).setChecked(true);
arrSelectedModel.add(arrModel.get(position));
} else {
arrModel.get(position).setChecked(false);
arrCheckboxState.set(position, false);
arrSelectedModel.remove(arrModel.get(position));
}
}
});
return convertView;
}
}
This is my adapter and I have taken boolean value public ArrayList<Boolean> arrCheckboxState for check and unchecked value but I am unable to get value of id which is checked where am doing mistake please tell me because I am getting value of id of all list-view item but I have to get only those id which is selected.
Remove this line..because your are not setting position as tag..as position is already there in parameters why are you getting it from tag ?
int position = (Integer) buttonView.getTag();
Use it like this
holder.checkBox
.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if(position<arrCheckboxState.size()){
if (isChecked) {
arrCheckboxState.set(position, true);
arrModel.get(position).setChecked(true);
arrSelectedModel.add(arrModel.get(position));
} else {
arrModel.get(position).setChecked(false);
arrCheckboxState.set(position, false);
arrSelectedModel.remove(arrModel.get(position));
}
}
}
});
I have an ExpandableListView with a contextmenu. It doesn't matter how many group items I have, it always returns 0.
My code:
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
ExpandableListView.ExpandableListContextMenuInfo info = (ExpandableListView.ExpandableListContextMenuInfo) menuInfo;
int group = ExpandableListView.getPackedPositionGroup((int) info.packedPosition);
int type = ExpandableListView.getPackedPositionType((int) info.packedPosition);
int child = ExpandableListView.getPackedPositionChild((int) info.packedPosition);
Log.d("Value ConTEXT: " + String.valueOf(group), String.valueOf(child) + " GROUP COUNT " + getExpandableListAdapter().getGroupCount());
menu.setHeaderTitle(((Person) dAdapter.getGroup(group)).getName());
// menu.add(0, 0, 0, "Geschiedenis verwijderen");
menu.add(1, 1, 1, "Verwijderen uit lijst");
}
And my custom base list adapter:
public class DrinkActionAdapter extends BaseExpandableListAdapter {
Activity context;
ArrayList<Person> personsGroup;
ArrayList<Person> personsChild;
public DrinkActionAdapter(Activity context, ArrayList<Person> personsGroup,
ArrayList<Person> personsChild) {
this.context = context;
this.personsGroup = personsGroup;
this.personsChild = personsChild;
}

Log.d(pp.getName(), pp.getName());
}
}
public Object getChild(int groupPosition, int childPosition) {
Log.d("GetChild" + String.valueOf(groupPosition), String.valueOf(childPosition));
return personsGroup.get(childPosition);

if (v == null) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = mInflater.inflate(R.layout.drink_action_child, null);

if (personsChild.size() != 0) {

public boolean hasStableIds() {

return true;
}
public boolean isChildSelectable(int groupPosition, int childPosition) {

}
}
Whenever I longclick on an item, it always selects the first one.
Try to register to the contextMenu in the getChildView() method just before return v; with this code ((Activity) context).registerForContextMenu(v);
