I am wanting to display orders on a screen which I retrieve from a database. Each order has various items on it, and the screen will show the details of various orders and their items.
For example:
Order 1
Item1
Item2
Item3
Order2
Item4
Item5
,etc.
I am able to return this data with no issues, however I was wondering how to put a border around each order (as opposed to each item which is easy to do).
This is what the return looks like now (apologies as it does not show everything I wanted in this image). Basically I want a border around each specific order, so all the items in order 1 I want in a border, and then all the items in order 2 I want in a border.
The code is outline below and any help would be greatly appreciated:
This is the activity which displays the orders:
public class ChefScreen extends AppCompatActivity {
ListView listView;
List<ChefOrderList> listOrders;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chef_screen);
listView = findViewById(R.id.list_chef_orders);
listOrders = new ArrayList<>();
displayOrders();
}
private void displayOrders(){
String url = "hidden";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject obj = new JSONObject(response);
JSONArray array = obj.getJSONArray("orders");
for (int i = 0; i < array.length(); i++) {
final JSONObject orderObj = array.getJSONObject(i);
ChefOrderList c = new ChefOrderList(orderObj.getString("menu_item_name"), orderObj.getString("item_type"), orderObj.getString("order_date_time"),
orderObj.getInt("quantity_ordered"), orderObj.getInt("order_id"));
listOrders.add(c);
}
ChefOrderAdapter adapter = new ChefOrderAdapter(listOrders, getApplicationContext());
listView.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(ChefScreen.this, "Oops! " +error.toString(), Toast.LENGTH_LONG).show();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("menuid", "0");
return params;
}
};
MySingleton.getInstance(this).addToRequestQueue(stringRequest);
}
}
This is the layout for the chef screen:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_marginStart="15dp"
android:layout_marginTop="81dp"
tools:layout_editor_absoluteX="20dp"
tools:layout_editor_absoluteY="77dp" />
</RelativeLayout>
The adapter:
public class ChefOrderAdapter extends ArrayAdapter<ChefOrderList> {
private List<ChefOrderList> chefOrderList1;
private Context context;
public ChefOrderAdapter(List<ChefOrderList> M, Context C){
super(C, R.layout.listcheforders, M);
this.chefOrderList1 = M;
this.context = C;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
View view = layoutInflater.inflate(R.layout.listcheforders,null,true);
TextView orderNumber = view.findViewById(R.id.tvOrderNumber);
TextView itemType = view.findViewById(R.id.tvItemType);
TextView itemName = view.findViewById(R.id.tvItemName);
TextView orderQuantity = view.findViewById(R.id.tvItemQty);
TextView orderTime = view.findViewById(R.id.tvDateTime);
ChefOrderList chefOrderList = chefOrderList1.get(position);
itemName.setText(chefOrderList.getName());
orderQuantity.setText("Qty: " +chefOrderList.getQty());
if(position>0){
ChefOrderList prevChefOrderList = chefOrderList1.get(position-1);
if(chefOrderList.getOrder() != (prevChefOrderList.getOrder())){
orderNumber.setText("Order: " +chefOrderList.getOrder());
orderTime.setText(chefOrderList.getDate());
}
if(!chefOrderList.getType().equals(prevChefOrderList.getType())){
itemType.setText(chefOrderList.getType());
}
} else {
itemType.setText(chefOrderList.getType());
orderNumber.setText("Order: " +chefOrderList.getOrder());
orderTime.setText(chefOrderList.getDate());
}
return view;
}
}
The model class:
public ChefOrderList(String name, String type, String date, int qty, int order) {
Name = name;
Type = type;
Date = date;
Qty = qty;
Order = order;
}
public String getDate() {
return Date;
}
public String getName() {
return Name;
}
public String getType() {
return Type;
}
public int getQty() {
return Qty;
}
public int getOrder() {
return Order;
}
}
and finally the layout file for the list or orders:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

This is the error I am getting
E/AndroidRuntime: FATAL EXCEPTION: main Process: com.autobus, PID: 10266
java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to android.widget.EditText
Screenshot of error:
In your bus_dataViewHolder class replace EditText to TextView.
because in layout you can use TextView and inside the program you use Edittext, that's while this issue generated.
This issue is because you take TextView in your adapter xml and get it like as a EditText.
So change in your adapter onCreateViewHolder from EditText to TextView .
Change below line in your adapter class.
TextView bus_number, total_seats, available_seats, bus_route, bus_leaving_time, bus_reaching_time,
bus_driver_name, bus_ticketchecker_name, bus_rating, bus_break_time, bus_company;
The Data from the web service is received properly, I got it checked by printing all the value in Log, so obviously there is no error from my back-end service. The data is also occupying blank space as per the array size of my list in layout, but i cannot see the data, only white screen with the TextView. There are no errors in the LogCat. I don't know what i did wrong, little help would be appreciated. Thanks
This is my MainActivity which has AsyncTask to fetch the Data.

You probably should be getting your B_OfferProducts from list passed to adapter, that is from List offerproductlist, instead of creating an object every time.
Regardless of what you put in the constructor of B_OfferProducts class, your items will not be bind to the list, which is probably the reason why data is not loading correctly. These objects created will live only inside ViewHolder.
This means that you should replace
B_OfferProducts b_offerProducts = new B_OfferProducts();
in onBindViewHolder() with getting the object relevant to the current postion in the list, so like this:
B_OfferProducts b_offerProducts = offerproductlist.get(position)
I hope it helps. Cheers!

The listWorkers contains 2 workers. But only one is getting populated in the cardview. The worker is the normal bean class. I am not able to see the 2nd worker card on the screen. Please help me out and suggest the changes.
