when i clik data adapter in ListView, i have a Error like:
Can you help me for resolve the error. I say very very thanks you for your help...

Seems you're trying to display all employees as a ListView... If my understanding is't wrong, you should :
Create an EmployeeBean
Put all your employee into a collection...maybe ArrayList.
After that, when you click an item on ListView, the integer you get is the index of EmployeeBean in your collection, so that you can access it from your collection.

Unable to parse image from Json to listview in android

I am trying to parse the images and text from url to list view.
I succesfully parse names but unable to parse Images. I follow these links....
I am getting bit map value null in image loader class..
I copied the MemoryCache and File Cache classes from the below links... Is there any mistake in my code?
My Json is: http://192.185.159.159/~charmmar/raj_spice/webservices/index.php?action=products
Is any problem for image parsing if json is large?

http://www.androidhive.info/2014/07/android-custom-listview-with-image-and-text-using-volley/
in these links all contained ImageLoader, FileCache, MemoryCache classes but I am unable to parse images... is any special library needed for this?

When used custom adapter always try to implement ViewHolder design pattern for ListView performance and use custom filter function instead Filterable implementation :
Custom filter funcation required two array list one is filterable data list and another one is for orignal data list :
public void filter(String constraint) {
filterData.clear();
if (constraint.length() == 0) {
filterData.addAll(orignalData);
}else{
for (HashMap<String,String> row: orignalData) {
if(row.get(Cardiology_updates.UpdateTitle).toUpperCase().startsWith(constraint.toString().toUpperCase())){
filterData.add(row);
}
}
}
notifyDataSetChanged();
}
Example :
et.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
adapter.filter(arg0.toString());
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1,int arg2, int arg3) {
}
#Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,int arg3) {
}
});
public class UpdatesAdapterList extends BaseAdapter {
private Context context;
private ArrayList<HashMap<String,String>> filterData;
private ArrayList<HashMap<String,String>> orignalData;
public ImageLoader imageLoader;
public UpdatesAdapterList(Context context,ArrayList<HashMap<String, String>> orignalData) {
this.context = context;
this.orignalData = orignalData;
filterData = new ArrayList<HashMap<String,String>>();
filterData.addAll(this.orignalData);
imageLoader = new ImageLoader(this.context);
}
#Override
public int getCount() {
return filterData.size();
}
#Override
public Object getItem(int position) {
return filterData.get(position);
}
#Override

return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.listview_updateitem, null);
holder.UpdateTitle = (TextView) convertView.findViewById(R.id.txtUpdatetitle);
holder.UpdateImage = (ImageView) convertView.findViewById(R.id.list_UpdateImage);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.UpdateTitle.setText(filterData.get(position).get(Cardiology_updates.UpdateTitle));
imageLoader.DisplayImage(filterData.get(position).get(Cardiology_updates.UpdateImage), holder.UpdateImage);
// Capture ListView item click
convertView.setOnClickListener(new View.OnClickListener() {

Pull to refresh GridView infinite loading/ fails to pull data

I can't seem to figure out what is going wrong with this, the code is pretty clean/ simple, but for some reason when I pull to refresh, it just shows me the loading icon infinity. Not only that, but I don't even receive any errors. The library I used for pull to refresh is this one.
I've spent several hours trying to figure this out, but the fact that it's not even giving me errors is making it very hard for me to track down.
And yes, I am sure the rest request is working.

You should POST to 10.0.2.2 instead of localhost in the call to RestClient.post in RestClientUsage.
I am not familiar withJsonHttpResponseHandler, but I would image there's an onFailure method (or something similar) that you may want to override. If there is, you may way to call mPullRefreshGridView.onRefreshComplete() in it.

The page loads without any exceptions.
In the log (through api.debug) I can see that the file is loaded and also that it get's parsed.
But I have to switch the tabs to see the changes.
How should I modify the code that it refreshes the listview as soon as the async method stops to load?

You have to override another method onPostExecute() inside AsyncTask like this:
#Override
protected Void onPostExecute(Void... unused) {
adpater.notifyDatasetChanged(); // will tell the adapter to refresh itself
}
