Android ExpandableListView notifyDataSetChanged - android

I have got problem with my code in Android application.
I have expandable list view with some data.
Periodically after 2 seconds, I use command NotifyDataSetChanged to update my all data.
The problem is that I have a seekbar and if I change progress then after this 2 seconds, the data was updated and the progress stops changing.
I don't know what I can do to update only row in expandable list view some row but not all.
final Handler handler = new Handler();
timer3 = new Timer();
czyUruchomionoTimer=true;
TimerTask doAsynchronousTask = new TimerTask() {
#Override
public void run() {
handler.post(new Runnable() {
public void run() {
exAdpt.notifyDataSetChanged();
}
});
}
};
timer3.schedule(doAsynchronousTask, 100, 2000);
}
Here is code of my Adapter:

In the Employee_List activity , you can access the data through index of child and group obtaining from ChildClickListener
myList.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView arg0, View arg1, int arg2,
int arg3, long arg4) {
// TODO Auto-generated method stub
//Here You can access the child data by
final EntryItem country = (EntryItem) listAdapter .getChild(arg2, arg3);
//From here you can pass the data through Intent

return false;

ExpandableListActivity how to check/uncheck checkbox in all children of a group

I have a ExpandableListActivity that has groups and children. the chidren have a checkbox.
I've overridden setOnGroupExpandListener for when the user tap the group.
How can i check/uncheck the checkbox for each child for a particular group?
I've tried getting the adapter and calling getChild using the groupPosition but i'm lost in how do do this.
thanks in advance

try creating an array of arrays of booleans called checked. then in getChildView check if that spot in the array is true, if so so the checkbox to checked.
then when you expand a parent loop through every element in that two dimential array setting them all to true and then calling notifyDataSetChanged
boolean [][] checked;
then in on expand
for(int i =0; i < checked[groupPosition].size; i++)
{
checked[groupPosition][i] = true;
}
notifyDataSetChanged();
in getChildView you should also but this
cb.setChecked(checked[groupPosition][childPosition]);
a sim thing can be done to uncheck them by setting it to false. just remember to update this array when a user checks or unchecks a button so when the list views are recycled you dont get randomly checked boxes.

use getListview() in list Activity to get List..........
in Oncreate
ListView lv = getListView();
http://www.mkyong.com/android/android-listview-example/
this link has both ways
1- overriding onListItemClick(
2- Setting you listener..
Try this way..
ListView lv = getListView();
lv. storelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
}
this are help you.
Thanks
Override the function onlistitemclick() for this. Here the integer position represents the postion of item that you had pressed
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
.......
}
Try this one
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
}
});

Android - cannot refresh ExpendableListView, it freezes

I have an ExpandableListView in which if I add some Groups during onCreate() of the activity, it's fine, but if I try to add Groups later on and then do notifyDataSetChanged() the ExpandableListView just freezes - everything else in the activity works, just the Exp.ListView hangs.
Here as you can see I add two Groups (with children) to the Exp.ListView and they function just fine. If I try to call addTeam() though it freezes/hangs.

A few things:
You don't want to make your TeamListAdapter a static subclass.
Try putting the logic for adding a team into an AsyncTask as this could freeze up the UI thread.
Also, what are your logs saying?
I solved this by using runOnUiThread in my addTeam() instead and it worked flawlessly.
