android rating bar in listview:How to save rating of multiple list in object?

I am designing faculty feedback activity.Below is my Fragment activity where i get faculty names from webservice as object and dispaly them in listview.And there is Rating bar infront every faculty.
I want to collect value of rating and faculty name in array of object and want to send feedback of every faculty to webservice to store when i click submit button.How can i do it?
FragmentTab2.java
public class TabFragment2 extends android.support.v4.app.Fragment implements View.OnClickListener {

this.ratingStar = ratingStar;
}
public void setEmployeeid(String employeeid)
{
this.employeeid = employeeid;
}
public String getEmployeeid()
{
return this.employeeid;
}
public void setEmployeename(String employeename)
{
this.employeename = employeename;
}
public String getEmployeename()
{
return this.employeename;
}
}
Any kind of knowledge and information will be thankful
EDIT
My list of ratings look like this.

and setVisibiltity(View.VISIBLE)for listview
Put this code here

}
}else{
courseEmptyLayout.setVisibility(LinearLayout.VISIBLE);
FacultyList.setVisibiltity(View.GONE) ;
}
progressDialog.dismiss();
}

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

Refresh list in Baseadaptor in Android

Hi,
I try to refresh my data with a tweet app which I am making. When I delete a following person by cliking on the button "following_del", I want that my list view being refreshed without the user I just deleted. Do you have any idea do to this? I am in a baseAdaptor class. Thanks

Return value from AsyncTask class onPostExecute method initialization value

Im reusing an Integer value that is calculated in th AsyncTask class and i need to create new instances of this class very often because the function calculated in the background needs to be done for every element of a ListView.
Im initializing a new BackgroundTask so i use this code in the main method called ShowItems(final Item item)
mBackgroundTask = new BackgroundTask(this);
mBackgroundTask.execute(item.getId(), (long)3);
Till here it works. then i need to create a new mBackgroundTask in a ToggleButton and this is where the problem arrises. i can't use this while defining the new class as i'll be getting the instance of the ToggleButton and not the original AsyncResponse
Here is my complete code
public interface AsyncResponse {
Integer processFinish(Integer result);
}
and
public class ItemView extends LinearLayout implements AsyncResponse{
public TextView prezzo;
public TextView scadenza;
public TextView followers;

Bundle bundle = new Bundle();
bundle.putInt("id", mPosition);
intent.putExtras(bundle);

}
}

If i understood this correctly, i think ItemView.this will solve your issue here.
Note: As pointed out in comment, you should run single AsyncTask to loop through all list items instead of creating new AsyncTask for each item.

Just save the string you want to show in button in a variable.
eg :
String temp=btnText;
Then call your list adapter again.
And make a change in your getView() as
buttonAction.setText(temp);
