public  class EfficientAdapter extends BaseAdapter implements Filterable {
        private LayoutInflater mInflater;
        private Context context;
         int pos;

        public EfficientAdapter(Context context) {

          mInflater = LayoutInflater.from(context);
          this.context = context;
        }

        public View getView(final int position, View convertView, ViewGroup parent) {
          ViewHolder holder;

            convertView = mInflater.inflate(R.layout.adaptor_contentposts, null);
convertView.setOnClickListener(new OnClickListener() {
              @Override
              public void onClick(View v) {

//click functionality } });

 MotionEvent event= MotionEvent.CREATOR.createFromParcel(null);
            switch (event.getAction()) 
            {
            case MotionEvent.ACTION_DOWN:
                //display click message
            }
            convertView.onTrackballEvent(event);





 return convertView;
        }

  class ViewHolder {
          TextView textLine;
          TextView textLine2;
          TextView PostedByAndPostedOn;
          ImageButton ImgButton;

        }

        @Override
        public Filter getFilter() {
            return null;
        }

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

        @Override
        public int getCount() {
          return ad_id.length;
        }

        @Override
        public Object getItem(int position) {
          return ad_id[position];
        }

      }
