NotifyDataSetChanged on gridview not working - Android

I am working with GridView. I want to update GridView on some basis. But notifyDataSetChanged() method is not working.
I am selecting tables on basis of section name. When I select section name very first time than I got tables of that section. But when I go to sections fragment again and select diff. section than I get previously selected tables only. That means notifyDataSetChanged() is not working.
What I have tried is like below.

At last I got the solution.
I have done like below...
I was maintaining a FLAG called getTableStatus to get the tables of particular section. If the value of getTableStatus is FALSE than only TableStatusAsync is called. At first selection of section, tables are coming from web service and those tables are being inserted in DB.
On second time, selecting of SECTION, tables are coming from DB not from web service. And tables are coming from DB are of previously selected SECTION. So, there is nothing to do with notifyDataSetChanged().
I have just change the FLAG value to FALSE by calling pref.setTableStatus(false); on selection of SECTION. Now, TableStatusAsync is called every time when you change your selection of SECTION.
Modified Code...
TableScreenSectionwiseActivity.java
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
pref.setSectionId(view.getTag().toString());
pref.setTableStatus(false);
pref.setTableServiceStatus(false);
Fragment fragment = new TableScreenActivity();
ReplaceFragment.getReplaceFragment(getActivity(), fragment, "");
}

Custom BaseAdapter doesn't call getView after resume app

i'm having some problems with a custom BaseAdapter which is showed in a PullToRefreshListView (whitch is an extension from ListView that you can update by pulling the list).
My problem is that when I minimize and later I resume my app, the ListView is not showing nothing... I had a breakpoint at my last line of code and my method getCount from my adapter return always more than zero, but getView still not being called...

Thanks!

I had just find an error in the activity that uses this adapter... But i don't understand this, and i'm not sure that it was the betters solution...
This method was the problem:
private static void CargarListasOfertas(OfertasLlenar_R oRespuesta){
try{
OfertasLlenar_R oRespuestFiltradas = (OfertasLlenar_R) oRespuesta.clone();
if(m_listaNavegaciones != null && m_listaNavegaciones.size() != 0){
final short paisID = m_listaNavegaciones.get(m_indice_actual).pais_id;
final short ciudadID = m_listaNavegaciones.get(m_indice_actual).ciudad_id;
Predicate<Oferta> ofertasPredicate = new Predicate<Oferta>() {
public boolean apply(Oferta oferta) {
return oferta.pais_id == paisID && oferta.ciudad_id == ciudadID;
}
};
Collection<Oferta> ofertas = General.Filtrar(oRespuestFiltradas.datos, ofertasPredicate);
oRespuestFiltradas.datos = new ArrayList<Oferta>(ofertas);
if(adapterOfertas == null){
adapterOfertas = new OfertasAdapter(activity, oRespuestFiltradas, oRespuesta);
lstOfertas.setAdapter(adapterOfertas);
}
else{
adapterOfertas.setDatos(oRespuestFiltradas);
}
}
else{
oRespuestFiltradas.datos = new ArrayList<Oferta>();
if(adapterOfertas == null){
adapterOfertas = new OfertasAdapter(activity, oRespuestFiltradas, oRespuesta);
lstOfertas.setAdapter(adapterOfertas);
}
else{
adapterOfertas.setDatos(oRespuestFiltradas);
}
oRespuestFiltradas.datos = new ArrayList<Oferta>();
}
final long ONE_MINUTE_IN_MILLIS = 60000;//millisecs
long t = Calendar.getInstance().getTime().getTime();
Date afterAddingTenMins = new Date(t + (10 * ONE_MINUTE_IN_MILLIS));
if(Datos.ventana_origen != Constantes.Ventanas_Origen.OfertasDetalle
|| (OfertasDetalleActivity.getFechaCarga() != null
&& !OfertasDetalleActivity.getFechaCarga().before(afterAddingTenMins))){
m_posicionOfertas = lstOfertas.getRefreshableView().getFirstVisiblePosition();
}
if(m_posicionOfertas != -1){
lstOfertas.getRefreshableView().setSelection(m_posicionOfertas);
}
General.OcultarCargando();
}
catch (Exception e){
e.printStackTrace();
General.OcultarCargando();
}
}
The code that now is working fine is:
private static void CargarListasOfertas(OfertasLlenar_R oRespuesta){
try{
OfertasLlenar_R oRespuestFiltradas = (OfertasLlenar_R) oRespuesta.clone();
if(m_listaNavegaciones != null && m_listaNavegaciones.size() != 0){
final short paisID = m_listaNavegaciones.get(m_indice_actual).pais_id;
final short ciudadID = m_listaNavegaciones.get(m_indice_actual).ciudad_id;
Predicate<Oferta> ofertasPredicate = new Predicate<Oferta>() {
public boolean apply(Oferta oferta) {
return oferta.pais_id == paisID && oferta.ciudad_id == ciudadID;
}
};
Collection<Oferta> ofertas = General.Filtrar(oRespuestFiltradas.datos, ofertasPredicate);
oRespuestFiltradas.datos = new ArrayList<Oferta>(ofertas);
}
else{
oRespuestFiltradas.datos = new ArrayList<Oferta>();
}
adapterOfertas = new OfertasAdapter(activity, oRespuestFiltradas, oRespuesta);
lstOfertas.setAdapter(adapterOfertas);
final long ONE_MINUTE_IN_MILLIS = 60000;//millisecs
long t = Calendar.getInstance().getTime().getTime();

}
if(m_posicionOfertas != -1){

Slow Application performance

I have developed a Contacts application. It does everything that a normal contacts application should does. There is always a chance of improvement. I had noticed in Android Emulator that loading for contact images starts when user has settled, he has scrolled the contact list to the area where there are chances are good that he would get contact he is searching for. So, I tried to implement the same thing on my app copy. I have implemented it. Its running very very slow. As I presume, I believe that application is running the thread multiple time even if it has retrieved the image which leads to big lagging. I am aware of the ASync task but just out of curiosity and to check whether it can be done, I don't wish to implement it here. Here is the source code for MainActivity.
package com.example.contact;
import java.io.InputStream;
import java.util.ArrayList;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;

import android.widget.ListView;
public class MainActivity extends ListActivity {
ListView listview;
private boolean mPaused;
private MyAdapter mAdapter;
private View view;
private boolean running = false;
final private ArrayList<String> con_ids = new ArrayList<String>();
private Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
listview = getListView();
context = this;
Cursor c = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null,
null,
null,
ContactsContract.Contacts.DISPLAY_NAME+" ASC");
if(c!=null)
{
for(c.moveToFirst();!c.isAfterLast();c.moveToNext()){
con_ids.add(c.getString(c.getColumnIndex(ContactsContract.Contacts._ID)));
}
}
mAdapter = new MyAdapter(this, android.R.layout.simple_list_item_1, con_ids);
listview.setAdapter(mAdapter);
listview.setOnScrollListener(makeScrollListener());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

}
private AbsListView.OnScrollListener makeScrollListener() {
return new AbsListView.OnScrollListener() {

setEnabled(scrollState != AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL);
running = false;
}
#Override
public void onScroll(AbsListView absListView, int i, int i1, int i2) {
String log = "";
Log.d(log, "Scroll First Item" + i);
Log.d(log, ""+ listview.getChildCount());
final int want = i;
running = true;
runOnUiThread(new Thread(new Runnable() {
int totalChild = listview.getChildCount();
int first = listview.getFirstVisiblePosition() - listview.getHeaderViewsCount();
int toRetrieve = want-first;
int id;
long con_id;
Bitmap thumbnail;
final ListView list = listview;
#Override
public void run() {
// TODO Auto-generated method stub
while(running)
{
if(!(toRetrieve<0||toRetrieve>=totalChild))
{
id = want+toRetrieve;
con_id = Long.valueOf(con_ids.get(id));
Uri ContactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, con_id);
InputStream stream = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(), ContactUri);
thumbnail = BitmapFactory.decodeStream(stream);
if(thumbnail == null)
{
toRetrieve++;
continue;
}
else
{
View view = list.getChildAt(toRetrieve);
if(view == null)
{
toRetrieve++;
continue;
}
else
{
ImageView iamge = (ImageView) view.findViewById(R.id.contact_iamge);
iamge.setImageBitmap(thumbnail);
}
toRetrieve++;
}
}
else
{
running = false;
}
}
}
}));
}
};
}
}
Code for MyAdapter,
package com.example.contact;

private String maindetail;
private SimplifiedContact contact;
private Drawable drawable;
public MyAdapter(Context context, int ResourceId, ArrayList<String> list)
{
super(context, ResourceId, list);
this.context = context;
ids = list;
infl = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
drawable = context.getResources().getDrawable(R.drawable.person);
}
static class ViewHolder
{
public ImageView image;
public TextView display_name;
public TextView main_detail;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
contact = new SimplifiedContact(context, Long.valueOf(ids.get(position)));
if(row == null)
{
row = infl.inflate(R.layout.single_cell, parent, false);
ViewHolder viewHolder = new ViewHolder();
viewHolder.display_name =(TextView) row.findViewById(R.id.disp_name);
viewHolder.main_detail = (TextView) row.findViewById(R.id.main_detail);
viewHolder.image = (ImageView)row.findViewById(R.id.contact_iamge);
row.setTag(viewHolder);
}
ViewHolder holder = (ViewHolder) row.getTag();
holder.display_name.setText(contact.getDisplayName());
holder.main_detail.setText(contact.getMainDetail());
holder.image.setBackgroundDrawable(drawable);
return row;
}
}
I wish to know, how this lag can be reduced. Thanks in advance.

Why don't you try to take that Thread instance that you are making in runOnUiThread and put It in a field, initializing It in the onCreate. I think that you are creating several thread instaces with no use.
public class MainActivity extends ListActivity {
ListView listview;
private boolean mPaused;
private MyAdapter mAdapter;
private View view;
private boolean running = false;
final private ArrayList<String> con_ids = new ArrayList<String>();
private Context context;
Thread uiThread;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
listview = getListView();
context = this;
Cursor c = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null,
null,
null,
ContactsContract.Contacts.DISPLAY_NAME+" ASC");
if(c!=null)
{
for(c.moveToFirst();!c.isAfterLast();c.moveToNext()){
con_ids.add(c.getString(c.getColumnIndex(ContactsContract.Contacts._ID)));
}
}
uiThread = new Thread(new Runnable() {
int totalChild = listview.getChildCount();
int first = listview.getFirstVisiblePosition() - listview.getHeaderViewsCount();
int toRetrieve = want-first;
int id;
long con_id;
Bitmap thumbnail;
final ListView list = listview;
#Override
public void run() {
// TODO Auto-generated method stub
while(running)
{
if(!(toRetrieve<0||toRetrieve>=totalChild))
{
id = want+toRetrieve;
con_id = Long.valueOf(con_ids.get(id));

toRetrieve++;
}
}

}
}
}
});
