public class CardAdapter extends BaseAdapter {

    private List<SuggestionResponse.UsersEntity> mSuggestion;
    private Context mContext;
    private LayoutInflater inflater = null;

    public CardAdapter(Context mContext, List<SuggestionResponse.UsersEntity> mSuggestion) {
        this.mContext = mContext;
        this.mSuggestion = mSuggestion;
        inflater = ( LayoutInflater )mContext.
                getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return mSuggestion.size();
    }

    @Override
    public Object getItem(int position) {
        return mSuggestion.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.each_card, parent, false);
        Holder holder = new Holder();
        holder.tv=(TextView) rowView.findViewById(R.id.textView1);
        holder.img=(ImageView) rowView.findViewById(R.id.imageView1);
        final SuggestionResponse.UsersEntity Suggestion = (SuggestionResponse.UsersEntity) getItem(position);
        holder.tv.setText(Suggestion.getFirstname());
        String Image_Url = Suggestion.getPhoto().get(0);
        Picasso.with(mContext).load(Image_Url).into(holder.img);
        rowView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
            }
        });
        return rowView;
    }

    public class Holder
    {
        TextView tv;
        ImageView img;
    }
}

Do you call BaseAdapter.notifyDataSetChanged() anywhere? You should do this any time your data is updated or added.

Hello Hi alexwalterbos,

I tried your Solution in but still no response if you have any working example bro ?

   flingContainer.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {
            @Override
            public void removeFirstObjectInAdapter() {
                // this is the simplest way to delete an object from the Adapter (/AdapterView)
                Log.d("LIST", "removed object!");
                al.remove(0);
                arrayAdapter.notifyDataSetChanged();
            }

[alexwalterbos]

Now you update the arrayAdapter only in the removeFirstObjectInAdapter(). That won't get triggered until you swipe a card, which obviously doesn't happen because the cards are not shown. I'll look into it later today, I'm on mobile at the moment.

Try adding notifyDataSetChanged() after you first add the data, I'd say it should work after you've called flingContainer.setAdapter(Adapter).

[ashokslsk]

Thanks i will try and let you know :)

Hi ashokslsk,

Did you fix that issue when add items from json respose

[ashokslsk]

@RajeshMobello

Yes i have fixed that ...

[RajeshMobello]

@ashok

Could you share where you did change the code.

[ashokslsk]

Hi @RajeshMobello ,

Please share where is your program struck my program is already in production.

[ttasterisco]

@RajeshMobello

you probably have this right now

[in your data fetch callback]
yourCustomAdapter = new CustomAdapter(getApplicationContext(), R.layout.view_card, yourData);
yourSwipeFlingAdapterView.setAdapter(yourCustomAdapter);

and it's not showing anything on the fling adapter view, right?

then adding mMixesAdapter.notifyDataSetChanged(); after setAdapter(...) should solve the problem
