protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Dismiss the progress dialog
productContent.notifyDataSetChanged();
lv.setAdapter(productContent);
}
}
}

Its easy try:
pDialog.dismiss();

STEP 1
Declare progress dialog above on create
private ProgressDialog pDialog;
STEP 2
Define preExecute method
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setTitle("Please wait");
pDialog.setMessage("Processing...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
pDialog.show();
}
STEP 3
//Your back ground task as it is
STEP 4
ADD postExecute Method
protected void onPostExecute()
{
pDialog.dismiss();
}

You need to just call dismiss() method for ProgressDialog. Like
protected void onPostExecute(){
pDialog.dismiss();
}

You have the progressBar variable that holds a reference to the progress bar in your layout. To hide it, call
progressBar.setVisibility(View.GONE);
The RelativeLayout you're placing the ProgressBar in is unnecessary. Also consider including the ProgressBar statically in your layout and just setting its visibility to VISIBLE/GONE as necessary.

In ListAdapter, getItem() should return an item using which you populate the Views

To get all values,
final CartAdapter adapter = (CardAdapter) lv.getAdapter();

i see 2 problem in your code:
1- you define your AsyncTask class like
AsyncTask<Void, Void, List<String>>
but you get Void on onPostExecute method, so you need change
protected void onPostExecute(Void result)
to
protected void onPostExecute(List<String> result)
2- you try access to finalResult on onPostExecute, bu you define that as static on JSONParserHandler so if you want access that you need :
JSONParserHandler.finalResult
but as you return that on doInBackground method so you can access that with:
result
that you get in onPostExecute.
then you need check result that is equal to null or not, because you return null after catch
your onPostExecute must be like:
protected void onPostExecute(List<String> result) {
// TODO Auto-generated method stub
if (null != mClient) {
mClient.close();
if (result != null)
{
ListAdapter adapter = new SimpleAdapter(
JsonActivityHttpClient.this, result,
R.layout.list_item, new String[] { PLACE_NAME_TAG, LATITUDE_TAG,
LONGITUDE_TAG, POSTAL_CODE_TAG }, new int[] { R.id.countryname,
R.id.lat, R.id.lng, R.id.postalcode });
setListAdapter(adapter);
}
else
// do any thing you want for error happened
}

String save =
EntityUtils.toString(response.getEntity(), HTTP.UTF_8);
return save;
}else {
return "Not Found";
}
}catch(Exception exception){}
return null;
}
}
}
Where the custome class is extends from base adapter in order to have list view with image view set to video image and text view set to video title.
In log cat messages the result are existed but my list view returns empty.
Can any one tell me why?
here is the code for costume list view:
public class custome extends BaseAdapter {
ArrayList<videos> data=new ArrayList<videos>();
android.content.Context context1;
android.widget.TextView name;
ImageView picture;
public custome(Context context,ArrayList<videos>arrayList) {
// TODO Auto-generated constructor stub
context=context;
arrayList=data;
}
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return data.get(arg0);
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
public View getView(int arg0, View arg1, ViewGroup arg2) {
View view=arg1;
if(view==null)
{
LayoutInflater layoutInflater=(LayoutInflater) _c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view=layoutInflater.inflate(R.layout.listvideo,null);
}
name=(TextView) view.findViewById(R.id.textView1);
picture=(ImageView) view.findViewById(R.id.imageView1);
videos video = data.get(arg0);
name.setText(video.getVideoname());
URL url = null;
try {
url = new URL(video.getImageurl());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Bitmap bitmap = null;
try {
bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
picture.setImageBitmap(bitmap);
return view;
}
}

The problem is in your assigning code of custome constructor:
Use this constructor:
public custome(Context context,ArrayList<videos> arrayList) {
context=context;
//arrayList=data;<<< WRONG
data=arrayList;//<<<<<<< Correct way of assigning
}

You are overriding your adapter here:
listview.setAdapter(new custome(MainActivity.this,videolist));

SherlockListActvity onItemClick not working

I'm working on an application and I've implemented sherlockListActvity to display list. But onItemClickListener is not working on this. I tried searching in internet and none of them worked for me. I did everything I found in the internet to solve this problem. Please help me on this. I'm newbie to android. The code goes like this.
