I don't know what's causing the problem. I can use the same method on my fragments but in this adapter it's not working.
Change
adapter = new AdapterPOI(getApplicationContext(), ....)
to
adapter = new AdapterPOI(this, ....)
in the code where you call the adapter's constructor. You get the error because getApplicationContext() cannot be casted to an ActivityCategorySelected. That's an Application context; whereas the adapter is expecting an Activity's context.

I think some of your items bannerUrls is empty. So if they're empty you do not set a default empty image with Glide or manually. Here i modified your code a little. I think this'll help.
#Override
public void onBindViewHolder(final SingleItemRowHolder holder, final int position) {
final HomePageList singleItem = mHomepageList.get(position);
holder.mTitle.setText(singleItem.getTitle());
if (!TextUtils.isEmpty(singleItem.getBannerUrl())) {
Glide.with(mContext).load(singleItem.getBannerUrl().get(0)).placeholder(R.drawable.placeholder).dontAnimate().into(holder.itemImage);
Log.e("Homebanner not empty", "url" + singleItem.getBannerUrl().toString() + "position" + position);
} else {
holder.itemImage.setImageResource(R.drawable.your_place_holder_for_empty_url);
}
}
Note: Also it's a better choice to use TextUtils.isEmpty(string) to instead of string.isEmpty() to avoid Null Pointer Exception.
Edit:
Also you can let Glide to put placeholder to your ImageView by removing the if statement.
if (!TextUtils.isEmpty(singleItem.getBannerUrl()))
I think this solution'll work you for too. If you choose this way do not forget to set an empty image to Glide for your empty or null urls.

This is just a guess but you are not parsing your packId while re initializing your list after deleting one item.
if(person.getString("responseCode").equals("1"))
{
JSONArray itemslist=person.optJSONArray("itemList");

{
Toast.makeText(BuyNowActivity.this, "Your Shopping Cart is Empty", Toast.LENGTH_SHORT).show();

JSONObject cartitems = itemslist.getJSONObject(j);
CartModel cvm = new CartModel();
cvm.setCart_Product_Name(cartitems.getString("prodNarration"));
cvm.setCart_Product_Price(cartitems.getString("finalPrice"));
cvm.setCart_Product_Id(cartitems.getString("productId"));
cvm.setCart_Product_Img(cartitems.getString("packLink"));
cvm.setCart_Product_Qty(cartitems.getString("qty"));
cvm.setCart_Product_packDiscount(cartitems.getString("packDIscDesc"));
// HERE add some code for parsing packId
cartlist.add(cvm);
}
Toast.makeText(BuyNowActivity.this, "Product Removed Successfully", Toast.LENGTH_SHORT).show();

Try adding the parsing code where i have added comment.
Hope this will help you.
Below is my complete adapter class of sendbird chatting.Currently date with time is displayed with every message.viewHolder.getView("left_time") and viewHolder.getView("right_time") are views for displaying date with time and it is calculated in method getDisplayDateTime.I want date with time to be displayed only when there is a change in date.For example if there is set of messages dated 23rd june then date with time should be displayed only for the first message with date 23rd june.
I tried doing that by detecting whenever there is a change in date by storing date in xyz variable and comparing it with date of every message and whenever they are unequal then making date view of that message visible and assigning the new date to xyz variable for comparison with future messages.But this approach fails when i scroll down and scroll up list.
What is the ideal approach for achieving this?

Try below code for your method,

//return strCurrentDate.equals(strPreviousDate) ? "" : strCurrentDate;

strPreviousDate = DateFormat.getDateFormat(context).format(strPreviousDate) + " " + DateFormat.getTimeFormat(context).format(strPreviousDate);
}
return strCurrentDate.equals(strPreviousDate) ? "" : strCurrentDate;
}
Now call your methods like below
if(position > 0)
{
final Object previousItem = getItem(position - 1);
Message previousMessage = (Message) previousItem;
viewHolder.getView("right_time", TextView.class).setText(getDisplayDateTime(mContext, message.getTimestamp(), previousMessage.getTimestamp()));
}
else
{
viewHolder.getView("right_time", TextView.class).setText(getDisplayDateTime(mContext, message.getTimestamp(), -1));
}
I had a similar problem (ref this SO Question) few months ago and nothing worked except extending from ArrayAdapter<MyObject> instead of BaseAdapter.
So, change the base class of your adapter to ArrayAdapter<MyObject> and implement the prompted method of the abstract class. you might need to move some you your existing code to these overridden methods for better performance.
You can force the system to redraw all items by calling BaseAdapter.notifyDataSetChanged()
The problem is that when i stretch up the pullToRefreshLiew (similar to listview), the memory the application occupy will be increasing step by step. I have tried many methods from the internet, but the bug still exists.
When i stretch up the pullToRefreshLiew, the memory will increasing to 90m
from 50m gradually.
Here is my memory monitor:
Here is my code below: (I omit the import code)
if you need my xml code,i will paste them as well.I am very grateful to you for your help.
