countOfHours = view.findViewById(R.id.itemCountOfHours);
parentLayout = view.findViewById(R.id.itemWorkDay);
}
}
}

Try adding this:
//Check if current item have description
if (workDayItemList.get(position).getDesc().length() > 2) {
Log.i(TAG, "TESTER: desc dote added");
holder.doteOfDesc.setVisibility(View.VISIBLE);
}
else if( workDayItemList.get(position).getDesc().length() < 2
&& holder.doteOfDesc.getVisibility()== View.VISIBLE ){
holder.doteOfDesc.setVisibility(View.GONE);
}
The reason why this is happening is that RecyclerView creates as many ViewHolders as its needed to cover a whole screen plus few extra ( 12 in your case) then reuses them via rebinding values to views. And you set doteOfDescto View.VISIBLE in 2. ViewHolder, but never set it back to View.GONE, thats why every time that ViewHolder is reused it will have doteOfDesc visible.
The Prettier version:
Boolean hasDescription = workDayItemList.get(position).getDesc().length() > 2;
holder.doteOfDesc.setVisibility( hasDescription ? View.VISIBLE : View.GONE);

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;

final ProductModel items = productItems.get(position);
if(view == null) {

LayoutInflater inflater = (LayoutInflater) context

viewHolder.checkBox = (CheckBox) view.findViewById(R.id.checkBox_productName);
viewHolder.decrease = (TextView) view.findViewById(R.id.decrease_product);

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);

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 to get the Position of an item's child view?

In list View I created Programmatically Image view and added in Linear Layout inside of ListView item.Below code I use for add Images in Adapter. Then how to get That image position.
Below I added my getView() method. I'm getting multiple Images in "String[] childDocument". using for loop I Sepreted Images from String[] and add in Linear Layout.

In this Image I'm dynamically added images. I want this perticular image position.

Android: Change color of all buttons in listview when a button pressed

In a listview, on each row, I have 10 buttons. When any of those buttons pressed, color of the buttons should changed (its like filling the bar based on where you pressed) .
Here is what I've done so far:
I have added references of each button to an ArrayList called buttons.
Also, I have an ArrayList which has colors strings.
This is click listener that is assigned to each button.
This is complete code form my adapter class of the listview.
public class TeacherRatingAdapter extends ArrayAdapter<Votes> {
private ArrayList<String> colors = new ArrayList();
private ArrayList<Button> buttons = new ArrayList<>();
private LayoutInflater inflater;
private ArrayList<Votes> mItems = new ArrayList<>();
private ArrayList<Votes> mItemsTemp = new ArrayList<>();
private int teacher;
private boolean myTeacher;
private ArrayList<Pair<Integer, Integer>> questionHint = new ArrayList<>();
private static int givenMark;
private HashMap<String, Integer> givenMarks = new HashMap<>();
ViewHolder viewHolder;
public TeacherRatingAdapter(Context context, TeacherRating teacherRating) {
super(context, -1, teacherRating.getVotes());
mItems = teacherRating.getVotes();
if(mItems.size()==0){
for(int i = 0; i<10; i++){
mItems.add(new Votes());
}
}
for(int i = 0; i<teacherRating.getVotes().size(); i++){
givenMarks.put(String.valueOf(i+1), teacherRating.getVotes().get(i).getAll().get(i));
}
teacher = teacherRating.getTeacher();
myTeacher = teacherRating.isMy_teacher();
questionHint.add(new Pair<>(R.string.question1, R.string.questionHint1));
questionHint.add(new Pair<>(R.string.question2, R.string.questionHint2));
questionHint.add(new Pair<>(R.string.question3, R.string.questionHint3));

It looks like this:
So, when I press button 3, all colors beyond 3, must become white. Or when I press button 9, all buttons before it must have its colors, and buttons in fron of it must be white. But this does not happen, and there is no error.
Thank you for any help.

Isn't that rating bar?
OnClickListener is wrong, I meant not the right listener, you got the idea wrong. What's the enclosing View?
