I can't display the timer in a TextView

I can't display the timer in a TextView - java

I've created a Listview with a Countdown timer and below is the code :

System.out.println("handler");
int hour = (int) ((timeLeftMS / (1000*60*60)) % 24);
int minute = (int) ((timeLeftMS / (60000)) % 60);
int seconde = (int)timeLeftMS % 60000 / 1000;
String timeLeftText = "";
if (hour<10) timeLeftText += "0";
timeLeftText += hour;
timeLeftText += ":";
if (minute<10) timeLeftText += "0";
timeLeftText += minute;
timeLeftText += ":";

timeLeftText += seconde;
txtTempsRestant.setText(timeLeftText);
}
};

The issue I have is that I want to display the timer (the timeLeftText String) in the txtTempsRestant TextView, but I can't access it. Can anyone give me advice?
When I print in the console and the output is correct, but I'm not able to display it. Should I change the way I'm working?

Modified Adapter class to make the count down work properly.

You don't want to declare the TextView static if you'll be changing the value.
Try declaring it outside the method here:
public class TicketAdapter extends ArrayAdapter<TicketModel> implements View.OnClickListener{
private ArrayList<TicketModel> dataSet;
Context mContext;
static long timeLeftMS = Long.valueOf(TicketModel.getTempsRestantTicket());
private TextView txtTempsRestant ;
// View lookup cache
private static class ViewHolder {
TextView txtName;
TextView txtType;
TextView txtDate;
TextView txtSLA;
ImageView info;
RelativeLayout layout;
TextView txtTempsRestant ;
}

Hi i have a code its good
beucse u dont need definination 3 textview for right and left ,....
You will create one TextView and use this code for create
private void Time() {
mCountTimer = new CountDownTimer(aTime, 1000) {
#Override
public void onTick(long millisUntilFinished) {
aMinute = (int) (millisUntilFinished / 1000) / 60;
mSecond = (int) (millisUntilFinished / 1000) % 60;
mTimer.setText(String.format(Locale.getDefault(), "%d:%02d", aMinute, mSecond));
}
#Override
public void onFinish() {
mTimer.setText(String.format(Locale.getDefault(), "%d:%02d", 0, 0));
mSend_Again.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Your EVENT
}
});
}
}.start();
}

Fragment loading data wrong data when I click in RecyclerView item

So I've been trying to fix this issue for so many hours but can't find the cause behind it.
Issue: My app shows data from my API into recyclerView, a standard feature. The issue comes when I use the search function. When I search for something, my search adapter shows the query data but going back to my Main fragment again, the view loader shows content fine but when I click on it, search items are actually being loaded instead.
Check my app to find out what I'm talking about: https://play.google.com/store/apps/details?id=envision.apps.newsextra
To reproduce, search for something, click on any article from search results, then go back and click any article from main feed, search items are actually being loaded instead.
Here's my main fragment:
public class FeedsFragment extends Fragment implements ArticleListener, LocalMessageCallback {

i want to change color of my textview inside of cardview when its value is "kritis" or "kurang" but somehow everytime when my textview in position 0 and its value is either kritis or kurang it always change color textiew in position 0 and also position 7, and also when its in position 1 it will set color text view in position 8 too and so... and then i try to use logd to see howmany times my setcolor initiate and its only 1x (when changing color only position 1 and 7) or 2x (when changing color text position 0,1,7,8)(my cardview is inside recyclerview)

this is how i send data to adapter

and this is my Datanote

try adding else to set default background color :
if(holder.textViewSKSkat.getText().equals("kritis") || holder.textViewSKSkat.getText().equals("kurang")){
holder.textViewSKSkat.setTextColor(Color.rgb(255,0,0));
Log.d("testing", "ayayaya");
} else {
holder.textViewSKSkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}
if(holder.textViewIPKkat.getText().equals("kritis") || holder.textViewIPKkat.getText().equals("kurang")){
holder.textViewIPKkat.setTextColor(Color.rgb(255,0,0));
Log.d("testing", "ayayaya");
} else {
holder.textViewIPKkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}

In My Case i tried this code..
holder.textview.setColor(ContextCompat.getColor(YourActivity.this,R.color.colorPrimary));

how to put a few data into array variable and post as JSONarray?

I'm trying to make a laundry ordering application. I've made it to the order process, at the end of the order process, the user clicks the next button to checkout the ordered results, I have successfully made the checkout results, but what I made is still in one variable string. how to put the checkout results into an array variable so that I can post the results in the form of JSONArray?
HERE IS MY ORDER ACTIVITY CODE :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_produk);
// menghubungkan variablel pada layout dan pada java
listProduk = (ListView)findViewById(R.id.list_produk);
swipeProduct = (SwipeRefreshLayout)findViewById(R.id.swipeProduct);
radioExpress = (RadioButton)findViewById(R.id.radio_express);
radioReguler = (RadioButton)findViewById(R.id.radio_regular);
tvTotal = (TextView)findViewById(R.id.total);
next = (Button)findViewById(R.id.button_next);
actionBar = getSupportActionBar();
laundry_id = getIntent().getStringExtra(TAG_LAUNDRY_ID);
// untuk mengisi data dari JSON ke dalam adapter
productAdapter = new CheckboxAdapter(this, (ArrayList<ProductModel>) productList, this);
listProduk.setAdapter(productAdapter);
listProduk.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
productAdapter.setCheckBox(position);
}
});
// menampilkan widget refresh
swipeProduct.setOnRefreshListener(this);
swipeProduct.post(new Runnable() {
#Override
public void run() {
swipeProduct.setRefreshing(true);
productList.clear();
tvTotal.setText(String.valueOf(0));
radioReguler.isChecked();
regular = true;
productAdapter.notifyDataSetChanged();
callProduct();
}
}
);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String checkbox = "";
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
formSubmit(dipilih);
}
});
}
private void formSubmit(String hasil){
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
View dialogView = inflater.inflate(R.layout.form_submit, null);
dialog.setView(dialogView);
dialog.setIcon(R.mipmap.ic_launcher);
dialog.setTitle("Menu Yang Dipilih");
dialog.setCancelable(true);
txtnamaProduk = (TextView) dialogView.findViewById(R.id.txtNama_produk);
txtnamaProduk.setText(hasil);
dialog.setNeutralButton("CLOSE", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
dialog.show();
}
AND HERE IS THE CODE OF THE RESULT :
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String checkbox = "";
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
formSubmit(dipilih);
}
});
}
in my code above, I still use the variable checkbox to accommodate all the results of the order chosen by the user. how to put all the result into array variable so i can post to server as a JSONArray? Please help me to solve this problem. because i'm still a beginner in android.
HERE IS MY ADAPTER CODE IF NEEDED :
public class CheckboxAdapter extends BaseAdapter{
private Context context;
private ArrayList<ProductModel> productItems;
ProdukLaundry produk;
public CheckboxAdapter(Context context, ArrayList<ProductModel> items, ProdukLaundry produk) {
this.context = context;
this.productItems = items;
this.produk = produk;
}
#Override
public int getItemViewType(int position) {
return position;
}
#Override
public int getCount() {
return productItems.size();
}
#Override
public Object getItem(int position) {
return productItems.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder viewHolder;
final ProductModel items = productItems.get(position);
if(view == null) {
viewHolder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_produk, null, true);
viewHolder.checkBox = (CheckBox) view.findViewById(R.id.checkBox_productName);
viewHolder.decrease = (TextView) view.findViewById(R.id.decrease_product);
viewHolder.count = (TextView) view.findViewById(R.id.count_product);
viewHolder.increase = (TextView) view.findViewById(R.id.increase_product);
viewHolder.price = (TextView) view.findViewById(R.id.product_price);
view.setTag(viewHolder);
}else{
viewHolder = (ViewHolder) view.getTag();
}
viewHolder.checkBox.setText(items.getProduct_name());
viewHolder.price.setText(items.getProduct_price());
viewHolder.count.setText(String.valueOf(items.getCountProduct()));
//fungsi untuk set posisi textview + dan -
viewHolder.increase.setTag(R.integer.btn_plus_view, view);
viewHolder.increase.setTag(R.integer.btn_plus_pos, position);
viewHolder.decrease.setTag(R.integer.btn_minus_view, view);
viewHolder.decrease.setTag(R.integer.btn_minus_pos, position);
//fungsi untuk disable textview + dan - jika checkbox tidak di klik
viewHolder.decrease.setOnClickListener(null);
viewHolder.increase.setOnClickListener(null);
if(items.isCheckbox()){
viewHolder.checkBox.setChecked(true);
viewHolder.increase.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View tempview = (View) viewHolder.increase.getTag(R.integer.btn_plus_view);
TextView tv = (TextView) tempview.findViewById(R.id.count_product);
Integer pos = (Integer) viewHolder.increase.getTag(R.integer.btn_plus_pos);
int countProduct = Integer.parseInt(tv.getText().toString()) + 1;
tv.setText(String.valueOf(countProduct));
productItems.get(pos).setCountProduct(countProduct);
produk.tambah(pos);
}
});
viewHolder.decrease.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View tempview = (View)viewHolder.decrease.getTag(R.integer.btn_minus_view);
TextView tv = (TextView) tempview.findViewById(R.id.count_product);
Integer pos = (Integer) viewHolder.decrease.getTag(R.integer.btn_minus_pos);
int total = productItems.get(pos).getCountProduct();
if (total>0){
int countProduct = Integer.parseInt(tv.getText().toString()) - 1;
tv.setText(String.valueOf(countProduct));
productItems.get(pos).setCountProduct(countProduct);
produk.kurang(pos);
}
}
});
} else {
viewHolder.checkBox.setChecked(false);
//fungsi untuk reset jumlah harga dan produk pada checkbox
String count = viewHolder.count.getText().toString();
int jumlah = Integer.parseInt(count);
int harga = Integer.parseInt(productItems.get(position).getProduct_price());
int kurang = jumlah * harga;
viewHolder.count.setText("0");
productItems.get(position).setCountProduct(0);
produk.kurangCheckbox(kurang);
}
return view;
}
public ArrayList<ProductModel> getAllData(){
return productItems;
}
public void setCheckBox(int position){
ProductModel items = productItems.get(position);
items.setCheckbox(!items.isCheckbox());
notifyDataSetChanged();
}
static class ViewHolder{
TextView decrease, count, increase, price;
CheckBox checkBox;
}
}

just create getter setter method of Arraylist like below
CompleteOrder:-
public class CompleteOrder {
List<OrderItem> order_items;
public List<OrderItem> getOrder_items() {
return order_items;
}
public void setOrder_items(List<OrderItem> order_items) {
this.order_items = order_items;
}
}
Create another Getter setter class of variable you want to add in arraylist
OrderItem:-
public class OrderItem {
String product_name;
int product_total;
public OrderItem(String product_name, int product_total) {
this.product_name = product_name;
this.product_total = product_total;
}
public String getProduct_name() {
return product_name;
}
public void setProduct_name(String product_name) {
this.product_name = product_name;
}
public int getProduct_total() {
return product_total;
}
public void setProduct_total(int product_total) {
this.product_total = product_total;
}
}
Now in your onClick method just create new List as below
public void onClick(View view) {
String checkbox = "";
CompleteOrder completeOrder=new CompleteOrder();
List<OrderItem> masterProductorderCount=new ArrayList<>();
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
masterProductorderCount.add(new OrderItem(holder.getProduct_name(),total);
}
}
completeOrder.setOrder_items(masterProductorderCount);
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
formSubmit(completeOrder);//pass object of CompleteOrder
}
});
CompleteOrder object give JSON output as below
{
"CompleteOrder":[
{
"product_name":"your product name",
"product_total":1
},
{
"product_name":"your product name",
"product_total":1
},
{
"product_name":"your product name",
"product_total":1
}
]
}

make a model that contains product name , total and etc,
then put each data into an object and put each object into an array
finally use Gson to map properties to model / list of models or the other way around.
ArrayList<Model> list = new ArrayList<>();
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
Model model = new Model();
model.productName = hold.getProduct_name();
model.total = total;
list.add(model);
}
}
String jsonArray = Gson().toJson(list);

You need to create a JSONObject for each entry in the JSONArray.
As far as I can see this should take care of it:
public void onClick(View view) {
String checkbox = "";
JSONArray jsonArray = new JSONArray();
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
JSONObject jsonObj = new JSONObject();
jsonObj.put("product_name", hold.getProduct_name());
jsonObj.put("product_total", total);
jsonArray.put(jsonObj);
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
String jsonArrayString = jsonArray.toString();
formSubmit(dipilih);
}
Depending on your data the resulting string from jsonArrayString would be:
{[
{"product_name":"product1","product_total":1},
{"product_name":"product2","product_total":2},
{"product_name":"product3","product_total":3}
]}
I really do not know what you intend on doing with the JSON data so I just created a String "jsonArrayString".. do what ever you need to with it.

How do I refresh a recyclerview in android?

I am populating the recycler view with new data on Activity
result.The problem is the new data is getting append at the end of the
recycler view how do I clear the previous data in the recycler view
and inflate the recycler view with the new data.
#Override
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mAdapter.notifyDataSetChanged();
search_info.clear();
book_type.clear();
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
getBookData(data);
if (books_list.size() > 0) {
books_list.clear();
mAdapter.swap(prepareData());
mAdapter.notifyDataSetChanged();
}
updateBooks(recyclerView);
mAdapter.notifyDataSetChanged();
}
}
}
This is the code for getBookData.
private void getBookData(Intent data) {
String singles = data.getStringExtra("singles");
String status_5in1series = data.getStringExtra("status_5in1series");
String special_issues = data.getStringExtra("special_issues");
String special_collection = data.getStringExtra("special_collection");
String status_3in1series = data.getStringExtra("status_3in1series");
String status_2in1 = data.getStringExtra("status_2in1");
String special_packs = data.getStringExtra("special_packs");
String junior = data.getStringExtra("junior");
String character_collections = data.getStringExtra("character_collections");
String single_digest = data.getStringExtra("single_digest");
String double_digest = data.getStringExtra("double_digest");
String toddler = data.getStringExtra("toddler");
String tinkle_treasure = data.getStringExtra("tinkle_treasure");
String ack = data.getStringExtra("ack");
String tinkle = data.getStringExtra("tinkle");
search_info.add(singles);
search_info.add(status_5in1series);
search_info.add(special_issues);
search_info.add(special_collection);
search_info.add(status_3in1series);
search_info.add(status_2in1);
search_info.add(special_packs);
search_info.add(junior);
search_info.add(character_collections);
search_info.add(single_digest);
search_info.add(double_digest);
search_info.add(toddler);
search_info.add(tinkle_treasure);
search_info.removeAll(Collections.singleton(null));
book_type.add(ack);
book_type.add(tinkle);
book_type.removeAll(Collections.singleton(null));
String search_array[] = (String[]) search_info.toArray(new String[search_info.size()]);
String books_array[] = (String[]) book_type.toArray(new String[book_type.size()]);
String books_info = dbHandler.searchForBooks(search_array, books_array).toString();
ParseLocBooks parseLocBooks = new ParseLocBooks(books_info);
parseLocBooks.parseJSON();
title = ParseLocBooks.title;
price = ParseLocBooks.price;
vol_no = ParseLocBooks.vol_no;
status = ParseLocBooks.status;
ISBN = ParseLocBooks.ISBN;
book_id = ParseLocBooks.book_id;
brand = ParseLocBooks.brand;
book_code = ParseLocBooks.book_code;
sku = ParseLocBooks.sku;
lang = ParseLocBooks.lang;
}
This is my code for prepareData.
private ArrayList prepareData() {
for (int i = 0; i < book_id.length; i++) {
BooksInfo booksInfo = new BooksInfo();
booksInfo.setTitle(title[i]);
booksInfo.setPrice(price[i]);
booksInfo.setVol_no(vol_no[i]);
booksInfo.setStatus(status[i]);
booksInfo.setISBN(ISBN[i]);
booksInfo.setBook_id(book_id[i]);
booksInfo.setBrand(brand[i]);
booksInfo.setBook_code(book_code[i]);
booksInfo.setSku(sku[i]);
booksInfo.setLang(lang[i]);
books_list.add(booksInfo);
}
return books_list;
}
And this is my DataAdapter code.
public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> {
private ArrayList<BooksInfo> books;
private Context ctx;
private String qty;
private RecyclerView recyclerView;
public DataAdapter()
{
}
#NonNull

});
}
public void updateNotes(ArrayList notesList) {
books = notesList;
}
public void updateQty(String q)
{

}
#Override

tv_qty = (TextView) itemView.findViewById(R.id.tv_qty);
}
public void setOnClickListener(View.OnClickListener onClickListener) {
itemView.setOnClickListener(onClickListener);
}
}
}
Any help or suggestion is appreciated.Thank you.

Notify your adapter to reflect the changes
mAdapter.notifyDataSetChanged();

clear your array list before adding object into:
private ArrayList prepareData() {
books_list.clear();
for (int i = 0; i < book_id.length; i++) {
BooksInfo booksInfo = new BooksInfo();
booksInfo.setTitle(title[i]);
booksInfo.setPrice(price[i]);
booksInfo.setVol_no(vol_no[i]);
booksInfo.setStatus(status[i]);
booksInfo.setISBN(ISBN[i]);
booksInfo.setBook_id(book_id[i]);
booksInfo.setBrand(brand[i]);
booksInfo.setBook_code(book_code[i]);
booksInfo.setSku(sku[i]);
booksInfo.setLang(lang[i]);
books_list.add(booksInfo);
}
return books_list;
}

Call this method
removeAllViews() on your recycler before setting a new Adapter.

Just clean your adapter's data, add new data to it and then call notifyDataSetChanged() on your adapter:
yourDataList.clear();
yourDataList.addNewObjects();
adapter.notifyDataSetChanged();
