How to get the values from LongSparseArray<Boolean>?

How to get the values from LongSparseArray<Boolean>? - java

I implemented the displaying contacts with checkboxes. When I selected the multiple contacts and click the button it shows this error "
Attempt to invoke virtual method 'boolean
java.lang.Boolean.booleanValue()' on a null object reference"
. at mCustomAdapter.mCheckedStates.get(i). So i wrote like this in adapter class is "
mCheckedStates = new LongSparseArray<>(ContactList.size())
And again it shows the same error after assigning some value. When I print the size of the mCustomAdapter.mCheckedStates.size it show the correct value of how many contacts I selected but when getting the value it shows the error. How to solve that?
This is My adapter class :
public class Splitadapter extends BaseAdapter implements Filterable,CompoundButton.OnCheckedChangeListener

// public SparseBooleanArray mCheckStates;
LongSparseArray<Boolean> mCheckedStates = new LongSparseArray<>();

Why my bookmarked words doesn't saved to sqlite database if i want to add them from another fragment?

The main problem is that when i add bookmark codes from direct recyclerview it works perfectly fine but when i add those codes to another fragment it just only show a toast that bookmark is added or deleted but that bookmarked word doesn't show in favorite list.

When i use bookmark codes from direct RecyclerView
When i use same bookmark codes from another fragment this happens
Any help will be heavily appreciated 🙏

Problem Solved
Just add those to RecyclerView
int position = this.getAdapterPosition();
Word word = wordList.get(position);
Bundle bundle = new Bundle();
bundle.putParcelable("allData", word);
Fragment detailsFragment = new TermThreeDetailsFragment();
detailsFragment.setArguments(bundle);
FragmentTransaction fT =((AppCompatActivity)context).getSupportFragmentManager().beginTransaction();
fT.replace(R.id.fragment_container, detailsFragment);
fT.addToBackStack(null);
fT.commit();
}
And add this codes to Fragment Class
word = new Word(Parcel.obtain());
Bundle bundle = this.getArguments();
if (bundle != null) {
word = bundle.getParcelable("allData");
termTextView.setText(word.getSanskrit());
descTextView.setText(word.getBangla());
}
*** You need to make you POJO class Parcelable to pass objects between fragments. ***

note: i get the data in 1st listview from strings.xml
please help me thank u in advance

You can add a column say 'isFavourite' in your db table which has list vew data. When user mark listitem as favourite, save the change in db table . When user navigates to favourite list populate the list from. db table with favourite filter in select query.

I suggest using SharedPreferences. You stated that your value gets overwritten. That won't be the case if you create multiple keys.
Example:
Say you have an ArrayList of String you want to pass from ClassA to ClassB:
ClassA:
for (int i = 0; i < list.size(); i++) {
sharedPref.edit().putString("text" + i, "abcde").apply();
}
ClassB:
for (int i = 0; i < list.size(); i++) {
sharedPref.getString("text" + i, null);
}
If you have problems with the listsize, you can also pass the listsize to sharedpref and retrieve it again.

Fill ExpandableListView with multiple items with AsyncTask

I want to fill an ExpandableListView with a custom Adapter. What I found online is having only one child(one TextView) as a child. In my case, I want to make it have multiple child and data filled after a Background task.
Please help me find what I've done wrong or what should I do as the error as I keep on getting

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 ArrayList<ProductModel> getAllData(){

}
public void setCheckBox(int position){
ProductModel items = productItems.get(position);
items.setCheckbox(!items.isCheckbox());
notifyDataSetChanged();
}
static class ViewHolder{

}

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.

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?

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();
}
