How to update the Expandable listview when new item is added to it

I have created an expandable listview which loads data from sqlite when the listview reaches bottom.It again loads another set of data from sqlite using async task.In this the header gets updated with the new datas but the child view for the latest data is empty can anyone tell me how to update/refresh the expandable list adapter when new data's get loaded.
Adapter:
public class DaybookExpandableAdapter extends BaseExpandableListAdapter {
String updatedate = "";
private Context _context;
private List<String> _listDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<Daybooklist>> _listDataChild;
private DatabaseHandler databaseHandler;
boolean isListScrolling;
public DaybookExpandableAdapter(Context context, List<String> listDataHeader,
HashMap<String, List<Daybooklist>> listChildData) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
}
#Override
public Object getChild(int groupPosition, int childPosititon) {
return this._listDataChild.get(this._listDataHeader.get(groupPosition))
.get(childPosititon);
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
#Override
public View getChildView(int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
/*final String childText = (String) getChild(groupPosition, childPosition);

I have already tried using notifydatasetchanged but it didn't works.

You need to set the adapter in the View, inside the onPostExecute() method:
protected void onPostExecute(String disorderedlist) {
listAdapter = new DaybookExpandableAdapter(getApplicationContext(), listDataHeader, listDataChild);
listView.setAdapter(listAdapter);
listAdapter.setTransactionList(listDataHeader,listDataChild);
loadingMore = false;
}

Using AlertDialog.Builder to build custom AlertDialog class

I have a Class FoodDialog that extends AlertDialog that I have customized to how I would like it to look.
I am now wanting to edit the positive/negative buttons using an AlertDialog.Builder, however, when I attempt to build an instance of FoodDialog using a builder, I am facing an 'Incompatible types' error where the builder is asking for AlertDialog instead I am providing it with an extension of AlertDialog - is there a way around this?
If not, is there a way I can edit the positive/negative buttons of my custom AlertDialog class FoodDialog?
Below is my FoodDialog class. The yes/no buttons I have there are ones I have created myself, but I would like the ones that are part of the AlertDialog.Builder to appear instead as these buttons get pushed out of sight when the soft keyboard appears:

You can catch your buttons click listener as follows:
yesBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//yes button click code here
}
});
noBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//no button click code here
}
});
You can use the logcat to see if your listener are being fired.

Custom List item change background in Android

Hi I am using custom listview and my list item contains checkbox. When updating the listview with the existing values the background is changed, so it is working fine.But when i clicks the check button, at that time the background will not changing after loading some where again then the background is changed .

I just want to change the background of the checked item immediatly without updating the list again.

I think you need to tell the BaseAdapter to refresh the data when your OnCheckedChanged Listener is called.
GuestListAdapter.this.notifyDataSetChanged()

Activity State not saved

I want to save my Activity state while I swipe between activities but I cannot. Some things are saved and the others dont. I think it has to do somehow with the gestureListener I'm impementing but I'm not sure.
When I swipe to a different activity and then back to this one - the AsyncTask is still running and the Handler is still updating the GUI, however, the views I have displaying in this activity and the buttons are all in their initial configuration.
what am I doing wrong?

You should not keep your Async task running in the background when your activity is send to the background. Your activity can be quit at any time so that you wouldn't have a reference to your activity anymore.
Regarding the preservation of state you could have a look at Activity.onRetainNonConfigurationInstance()
