problem with scrolling up or down of listview

When I try to take all the values of the NumberPicker, it correctly returns the ones in the middle, while the first and last returns only the last one that has been modified between them. I don't understand where I'm wrong.
public class piatto {
String nome;
String Descrizione;
String prezzo;
String immagine;
String tag;
public piatto(String nome, String Descrizione, String prezzo, String immagine, String tag) {
this.nome= nome;
this.Descrizione= Descrizione;
this.prezzo= prezzo;
this.immagine=immagine;
this.tag=tag;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getDescrizione() {
return Descrizione;
}
public void setDescrizione(String descrizione) {
Descrizione = descrizione;
}
public String getPrezzo() {
return prezzo;
}
public void setPrezzo(String prezzo) {
this.prezzo = prezzo;
}
public String getImmagine() {
return immagine;
}
public void setImmagine(String immagine) {
this.immagine = immagine;
}
public String getTag() {
return tag;
}
public void setTag(String tag) {
this.tag = tag;
}
}
this is my adapeter
public class ProductListAdapterforListView extends BaseAdapter {
private Context mContext;
private List<piatto> mProductList;
public ProductListAdapterforListView(Context mContext, List<piatto> mProductList) {
this.mContext = mContext;
this.mProductList = mProductList;
}
#Override
public int getCount() {
return mProductList.size();
}
#Override
public piatto getItem(int position) {
return mProductList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View listitemview ;
if (convertView==null){
listitemview = View.inflate(mContext, R.layout.row_data_list, null);
ImageView i = (ImageView) listitemview.findViewById(R.id.imagepiatto);
com.shawnlin.numberpicker.NumberPicker numberPicker = (com.shawnlin.numberpicker.NumberPicker) listitemview.findViewById(R.id.number_picker);
TextView n=(TextView) listitemview.findViewById(R.id.namepiatto);
TextView p=(TextView) listitemview.findViewById(R.id.prezzopiatto);
n.setText(mProductList.get(position).getNome());
p.setText(mProductList.get(position).getPrezzo()+" €");
Picasso.get().load(mProductList.get(position).getImmagine()).into(i);
} else {
listitemview=convertView;
}
return listitemview;
}
}
And this is my Java class where I get the values of the NumberPicker of each Item
#Override
public void onClick(View view) {
if (view.getId()==R.id.buttonnext){
Float totale = (float) 0.0;
String listapiatti="";
for (int i = 0; i < listView.getChildCount(); i++) {
view = listView.getChildAt(i);
TextView n = view.findViewById(R.id.namepiatto);
String nome = n.getText().toString();
TextView p = view.findViewById(R.id.prezzopiatto);
String pricestr = p.getText().toString();
String[] prezzo = pricestr.split(" ");
Float price = Float.valueOf(prezzo[0]);
com.shawnlin.numberpicker.NumberPicker numberPicker = (com.shawnlin.numberpicker.NumberPicker) view.findViewById(R.id.number_picker);
int value = numberPicker.getValue();
if (value != 0) {
totale = totale + (price * value);
listapiatti = listapiatti + nome + ": " + value + ", ";
Toast.makeText(getApplicationContext(), String.valueOf(i)+" "+value,
Toast.LENGTH_LONG).show();
}
}
String finale=String.valueOf(totale);
startActivity(new Intent(carrello3.this, ordine.class));
}
if (view.getId()==R.id.buttonback){
onBackPressed();
}
}

it doesn't seem like a good idea to create an object on setOnScrollListener which gets called many many times during scrolling up/down. if you could provide more detail would be great.

How to get videos folder?

I am working on a video player app. I have two fragments: one is AllVideolist fragment and the other one is Videos folders fragment. The AllVideoListenter code here fragment is working fine, but I don't know how to show get all videos folder.
This is my MainActivity.java code.
MainActivity.java
public ArrayList<videoFiles> getAllVideos(Context context) {
ArrayList<videoFiles> tempArrayList = new ArrayList<>();
Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String [] projection = {
MediaStore.Video.Media._ID,
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.TITLE,
MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.SIZE,
MediaStore.Video.Media.DATE_ADDED,
MediaStore.Video.Media.DURATION
};
Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);
if (cursor!= null){
while (cursor.moveToNext()){
String id =cursor.getString(0);
String path =cursor.getString(1);
String title =cursor.getString(2);
String fileName =cursor.getString(3);
String size =cursor.getString(4);
String dateAdded =cursor.getString(5);
String duration =cursor.getString(6);
int durationa = Integer.parseInt(duration);
String duration_formet;
int sec = (durationa/1000)%60;
int min = (durationa/(1000*60))%60;
int hours = durationa/(1000*60*60);
if (hours == 0){
duration_formet = String.valueOf(min).concat(":" .concat(String.format(Locale.UK, "%02d",sec)));
}else {
duration_formet = String.valueOf(hours).concat(":" .concat(String.format(Locale.UK, "%02d",min).concat(":" .concat(String.format(Locale.UK, "%02d",sec)))));
}
videoFiles videoFiles = new videoFiles(id, path, title,fileName,size, dateAdded,duration_formet);
Log.d("path", path);
tempArrayList.add(videoFiles);
}
cursor.close();
}
return tempArrayList;
}
I craete this model class.
VideoFiles.java
public class videoFiles {
///------------------MODEL CLASS ---------------
private String id;
private String path;
private String title;
private String fileName;
private String size;
private String dateAdded;

public videoFiles(String id, String path, String title, String fileName, String size, String dateAdded, String duration) {
this.id = id;
this.path = path;
this.title = title;
this.fileName = fileName;
this.size = size;
this.dateAdded = dateAdded;
this.duration = duration;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPath() {
return path;
}
public void setPath(String path) {
this.path = path;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getFileName() {
return fileName;
}
public void setFileName(String fileName) {
this.fileName = fileName;
}
public String getSize() {
return size;
}
public void setSize(String size) {
this.size = size;
}
public String getDateAdded() {
return dateAdded;
}
public void setDateAdded(String dateAdded) {
this.dateAdded = dateAdded;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
This is folder Adapter.
FolderAdapter.java
public class FolderAdapter extends RecyclerView.Adapter<FolderAdapter.folderViewHolder> {
View view;
Context context;
private ArrayList<videoFiles> folderList;
public FolderAdapter(Context context, ArrayList<videoFiles> folderList) {
this.context = context;
this.folderList = folderList;
}
#NonNull
#Override
public FolderAdapter.folderViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
view = LayoutInflater.from(context).inflate(R.layout.foldeitems, parent, false);
return new folderViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull FolderAdapter.folderViewHolder holder, int position) {
holder.folderName.setText(folderList.get(position).getPath());
}
#Override
public int getItemCount() {
return folderList.size();
}
public class folderViewHolder extends RecyclerView.ViewHolder {
TextView folderName;
public folderViewHolder(#NonNull View itemView) {
super(itemView);
folderName = itemView.findViewById(R.id.foldername);
}
}
}
This is main foledr fragment. I want to show videos in folder by folder
FoldeFragment.java
public class FolderFragment extends Fragment {
View view;
RecyclerView recyclerView;
public FolderFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
view= inflater.inflate(R.layout.fragment_folder, container, false);
recyclerView = view.findViewById(R.id.folderRecylerView);
return view;
}
}

There is no "videos folder" in Android. There are number of default locations for videos, but they vary from device to device. Devices that have expandable memory often have video storage defaults that don't exist on non-expandable devices. User are not obliged to put video files in these default locations, anyway.
If you want to get a list of all directories that contain video files, you'll either need to implement some sort of search/index operation yourself, or use the built-in media database. You should be able to enumerate the list of videos from the database, and extract the unique folder names.
For what it's worth, I answered a similar question here:
How to show only videos folder?

Getter returning null when testing get methods

I am trying to get data from my database to show on a listview. The problem I am having is it seems the getters are not working properly. When I test what they are returning, it comes back null.
Any insight would be appreciated as I am lost here. Thanks in advance.
Here is where I initialise the class:
public ArrayList<GameStats> getAllData() {
ArrayList<GameStats> arrayList = new ArrayList<>();
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery("SELECT * FROM savedGamesTable", null);
while(cursor.moveToNext()){
int id = cursor.getInt(0);
String lName = cursor.getString(1);
int lScore = cursor.getInt(2);
String rName = cursor.getString(3);
int rScore = cursor.getInt(4);
String notes = cursor.getString(5);
GameStats gameStats = new GameStats(id, lName, lScore, rName, rScore, notes);
arrayList.add(gameStats);
}
return arrayList;
}
Here is where I am trying to use the getters:
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.activity_saved_games, null);
TextView lName = convertView.findViewById(R.id.lName);
TextView lScore = convertView.findViewById(R.id.lScore);
TextView rName = convertView.findViewById(R.id.rName);
TextView rScore = convertView.findViewById(R.id.rScore);
TextView notes = convertView.findViewById(R.id.notes);
GameStats gameStats = arrayList.get(position);
testVar = gameStats.getlName();
Log.d("MyAdaptor","gameStats = " + var);
lName.setText(gameStats.getlName());
lScore.setText(String.valueOf(gameStats.getlScore()));
rName.setText(gameStats.getrName());
rScore.setText(String.valueOf(gameStats.getrScore()));
notes.setText(gameStats.getNotes());
return convertView;
}
Here is the model class:
public class GameStats {
int id, lScore, rScore;
String lName, rName, notes;
public GameStats(int id, String lName, int lScore, String rName, int rScore, String notes) {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getlScore() {
return lScore;
}
public void setlScore(int lScore) {
this.lScore = lScore;
}
public int getrScore() {
return rScore;
}
public void setrScore(int rScore) {
this.rScore = rScore;
}
public String getlName() {
return lName;
}
public void setlName(String lName) {
this.lName = lName;
}
public String getrName() {
return rName;
}
public void setrName(String rName) {
this.rName = rName;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
}
and here is where I am calling the methods:
public class SavedGameScreen extends AppCompatActivity {
ListView lv1;
ArrayList<GameStats> arrayList;
MyAdaptor myAdaptor;
DatabaseHelper databaseHelper;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_saved_game_screen);
lv1 = findViewById(R.id.lv1);
databaseHelper = new DatabaseHelper(this);
arrayList = new ArrayList<>();
loadData();
}
private void loadData() {
arrayList = databaseHelper.getAllData();
myAdaptor = new MyAdaptor(this, arrayList);
lv1.setAdapter(myAdaptor);
myAdaptor.notifyDataSetChanged();
}
}

Please change the constructor as below and see if that works,
public GameStats(int id, String lName, int lScore, String rName, int rScore, String notes) {
this.id = id;
this.lName = IName;
this.lScore = IScore;
this.rName = rName;
this.rScore = rScore;
this.notes = notes;
}

In your model class initialize the variables using constrtuctor. I guess that is the problem. Since you are not initializing the model class properties, it the getters will return "null" or any garbage value

You are passing the values to the model constructor but you are not assigning it to the model variables. You need to change the code as below,
public GameStats(int id, String lName, int lScore, String rName, int rScore, String notes) {
this.id = id;
this.lName = IName;
this.lScore = IScore;
this.rName = rName;
this.rScore = rScore;
this.notes = notes;
}
Else initialise each variable through setter() method.

I get an error while creating a listview adapter

I would create some listview from my api json response, but I stuck with this LinkedTreeMap error in my code. Could anyone help me to solve this?
public class KategoriListAdapter extends BaseAdapter {

public KategoriListAdapter(Context context, ArrayList<Barang> barang) {
this.context = context;
this.barang = barang;

return view;
}
}

}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getNama() {
return nama;
}
public void setNama(String nama) {
this.nama = nama;
}
public String getHarga() {
return harga;
}
public void setHarga(String harga) {
this.harga = harga;
}
public String getGambar() {
return gambar;
}
public void setGambar(String gambar) {
this.gambar = gambar;
}
}
The log result while I run the activity is
java.lang.ClassCastException: com.example.barangkoz.model.Barang cannot be
cast to com.google.gson.internal.LinkedTreeMap
at com.example.barangkoz.activities.KategoriListAdapter.getView(KategoriListAdapter.java:57)`

You are passing ArrayList of "Barang" Object in you adapter constructor it means you already have a list of object Barang in your adapter and you can directly use it without casting to TreeMap.
In your getView method of adapter change this
Object getrow = this.barang.get(i);
to
Barang barang = barang.get(i);
it will give the Barang object at the position of i from the list of Barang.
and you can get the data from this object using the getters methods defined inside your object Barang like this.
String harga = barang.getHarga();
String nama = barang.getNama();
String userName = barang.getUsername();
and set it to your TextView or
You can directly set the data to TextView from Barang object (without doing extra step to setting it in variable before setting to TextView), like this
tvHarga.setText(barang.getHarga());
tvNama.setText(barang.getNama());
tvUsername.setText(barang.getUsername());

Replace
Object getrow = this.barang.get(i);
LinkedTreeMap<Object, Object> rowmap = (LinkedTreeMap) getrow;
String nama = rowmap.get("nama").toString();
String harga = rowmap.get("harga").toString();
String username = rowmap.get("username").toString();
With
Barang getrow = this.barang.get(i);
String nama = getrow.getName();
String harga = getrow.getHarga();
String username = getrow.getUsername();

In your writeToParcel() method, you have
parcel.writeInt(id);
Since id is Integer, this is going to auto-unbox id. If id is null, this auto-unboxing will throw a NullPointerException.
Since there is no Parcel.writeInteger() method, you're going to have to record whether or not id is null in a separate write. Something like:
if (id == null) {
dest.writeInt(0);
}
else {
dest.writeInt(1);
dest.writeInt(id);
}
And to read it back out:
int hasId = in.readInt();
if (hasId == 1) {
id = in.readInt();
}
else {
id = null;
}

The order in which you read the values from the parcel has to be the same as the order it was written to it.
Try:
protected Cast(Parcel in) {
name = in.readString();
profilePath = in.readString();
character = in.readString();
id = in.readInt();
}
