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();
}
});

check one box multiple boxes are checked

I am using custom listViewAdapter class and I want to check one box in a single row, but it is checking multiple checks in multiple rows which is not my requirement. Please tell me how can I resolve it.

Write all your checkbox logic inside you adapter getView method. That will work .

You can try this,
Change your code
if(results.size() > 0){
SearchAdapter searchAdapter = new SearchAdapter(SearchActivity.this);
searchAdapter.setData(results);
mListViewSearchUsers.setAdapter(searchAdapter);
textNotFound.setVisibility(View.GONE);
}else {
textNotFound.setVisibility(View.VISIBLE);
textNotFound.setText("No users found");
}
to
if(results.size() > 0){
SearchAdapter searchAdapter = new SearchAdapter(SearchActivity.this);
if (searchAdapter== null) {
searchAdapter.setData(results);
mListViewSearchUsers.setAdapter(searchAdapter);
} else {
searchAdapter.setData(results);
mListViewSearchUsers.notifyDatasetChange();
}
textNotFound.setVisibility(View.GONE);
}else {
textNotFound.setVisibility(View.VISIBLE);
textNotFound.setText("No users found");
}
Change some code in adapter (comment some code)
public void setData(List<User> data) {
// clear();
if (data != null) {
addAll(data);
// notifyDataSetChanged();
}
}
Update:(problem resolved by comm‌​ents this line)
mListViewTimeline.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
I hope this will help you.

Android Listview duplicates on15th row onwards

iam currently doing a project in which i populate a Listview from JSON.
The JSON iam passing works perfectly and my listview shows all list values properly But problem occurs when i click on any list after 10/12th list the values which i get is repeated from the first.
The respective values are not retrieved.
I also refereed other post regarding this issue but now solved my problem.
Below is my code. I hope someone will find the solution for it.
