Android - Firebase Realtime database not working for this library

I have been using firebase for my app, all works fine, however, I recently updated my UI, by adding this library, the other data in my listview but this library's view does not update, can someone please help me with this, and there's one more issue with my code, when I update the status, i.e the library's view, only the selected items view should be updated, instead all the views in my list get updated, say if I select "Received" for one item in the list, all others get updated to "Received", this does not reflect in the firebase console, and when I re open the app, everything will fixed. Please assist me with this. Here' my git repository link if needed.

You should move data manipulation to the adapter, and design-wise it would make sense and might also fix the problem you're telling us.
Write this method in your ProductAdapter:
public void removeSelected() {
for(int i = mProductList.size()-1; i >= 0; i--) {
if(mProductList.get(i).selected) {
mProductList.remove(i);
}
}
notifyDataSetChanged();
}
Update your OnClickListener (in your ShoppingCartActiity of course):
removeButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mProductAdapter.removeSelected();
}
});
Edit
I noticed that you aren't applying OOP's concept of encapsulation here. That is, ShoppingCartActiity shouldn't be making changes to the data which belongs to your adapter.
So, just create public methods inside the ProductAdapter for item for selection, etc and call them from ShoppingCartActiity as needed.
Copy this method in your ProductAdapter:
public void toggleSelection(int position) {
Product selectedProduct = (Product) getItem(position);
if(selectedProduct.selected) { // no need to check " == true"
selectedProduct.selected = false;
}
else {
selectedProduct.selected = true;
}
notifyDataSetInvalidated();
}
mProductAdapter.toggleSelection(position); will replace following code ShoppingCartActiity:
Product selectedProduct = mCartList.get(position);
if(selectedProduct.selected == true)
selectedProduct.selected = false;
else
selectedProduct.selected = true;
mProductAdapter.notifyDataSetInvalidated();
Edit2
The problem is that the ShoppingCartActiity takes items from ShoppingCartEntry on starting up, but it never writes back the changes to it when you remove items.
update your removeButton's onClick() to:
mProductAdapter.removeSelected();
if (product.selected) {
// set products which are remaining in the adapter
ShoppingCartHelper.setProducts(mProductAdapter.getProducts());
}
ShoppingCartHelper.setProducts() would replace the old data with the passed one:
public static void setProducts(ArrayList<Product> products) {
catalog = new Vector<Product>();
for (Product product : products) {
catalog.add(product);
}
}
mProductAdapter.getProducts() will just return the list of Products, like:
public List<Product> getProducts() {
return mProductList;
}

you just have to remove selected item from list, and after adapter.notifiyDataSetChanged() it will refresh the adapter.
removeButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Loop through and remove all the products that are selected
// Loop backwards so that the remove works correctly
for(int i=mCartList.size()-1; i>=0; i--) {
if(mCartList.get(i).selected) {
mCartList.remove(i);
//mProductAdapter.removeSelected();
}
}
if(mProductAdapter!=null)
mProductAdapter.notifyDataSetChanged();
}
});

You can use this
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> arg0, View v,
int index, long arg3) {
// TODO Auto-generated method stub
Log.d("in onLongClick");
//Open alert dialog here
return true;
}
});
