When I press the button to delete an item from ListView it deletes the last one

I have next problem with a list view: So on the layout (prod_row) I set an image view(rvCls) that I want to delete an item while clicked. It deletes an item, but is always the last one. If I close this activity and I reopen it, it deletes the correct item, but what should I do to see the change instantly and not have to refresh the page?
on the Cos class I build logic for list view and cosAdapter is the Adapter class for my list view
COS class the one with the list view
public class Cos extends AppCompatActivity {
ListView lvProd;
SwipeMenuListView listView;
Button btnTrm, btnCls;
TextView tvTotal;
DatabaseReference mDatabase;
ArrayList<Produs> list = new ArrayList<Produs>();
String email;
Integer contor = 1;
ImageView rvCls;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cos);
FirebaseAuth mAuth;
mAuth=FirebaseAuth.getInstance();
FirebaseUser currentUser = mAuth.getCurrentUser();
email = currentUser.getEmail();
tvTotal = findViewById(R.id.tvTotal);
btnTrm = findViewById(R.id.btnTrm);
Intent i = getIntent();
list = (ArrayList<Produs>) i.getSerializableExtra("set");
Double total = 0.0;
for(Produs p: list){
total+= Double.valueOf(p.getPret()) * p.getQt();
}
Calendar rightNow = Calendar.getInstance();
int hour = rightNow.get(Calendar.HOUR_OF_DAY);
if(hour == 15){
total /= 2;
}
tvTotal.setText("Total: " + String.valueOf(total) + " lei");
btnTrm = findViewById(R.id.btnTrm);
btnCls = findViewById(R.id.btnCls);
// lvProd = findViewById(R.id.lvProd);
listView = (SwipeMenuListView) findViewById(R.id.listView);
mDatabase = FirebaseDatabase.getInstance().getReference().child("Istoric");
try {
ArrayAdapter<Produs> adapter = new cosAdapter(this, 0 ,list);
listView.setAdapter(adapter);
}catch (Exception e){
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
btnCls.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try{
Intent intent = new Intent(getApplicationContext(),MainActivity.class);
intent.putExtra("set",(Serializable)list);
startActivity(intent);
}catch (Exception e){
Toast.makeText(Cos.this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
btnTrm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(Produs p : list){
IstoricData id= new IstoricData(email,p.getNume(),false,p.getQt());
Task t = mDatabase.push().setValue(id);
contor ++;
t.addOnCompleteListener(new OnCompleteListener() {
#Override
public void onComplete(#NonNull Task task) {
Toast.makeText(Cos.this, "Comanda a fost trimisa cu succes", Toast.LENGTH_SHORT).show();
}
});
t.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(Cos.this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
startActivity(new Intent(getApplicationContext(),MainActivity.class));
}
});
}
}
COS adapter the adapter class for my list view adapter
public class cosAdapter extends ArrayAdapter<Produs> {
private Context context;
//private List<Produs> produse;
ArrayList<Produs> produse;
public cosAdapter(Context context, int resource, ArrayList<Produs> objects){
super(context, resource, objects);
this.context = context;
this.produse = objects;
}
#NonNull

rvNume.setText(model.getNume());
rvCantitate.setText("Cantitate: "+model.getCantitate()+" grame");
rvQT.setText("Numar: x" +String.valueOf(model.getQt()));
Picasso.get().load(model.getImage()).into(rvImage);
rvCls.setOnClickListener(new View.OnClickListener() {

There are 2 ways you could fix your code:
1.) Set position value as tag to your rvCls and fetch this tag for usage of position in your ClickListener
rvCls.setTag(position);
rvCls.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
produse.remove((int)v.getTag());
notifyDataSetChanged();
}
});
2.) Use a variable finalPosition in getView and use that as position inside ClickListener.
final int finalPosition = position;
rvCls.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
produse.remove(finalPosition);
notifyDataSetChanged();
}
});

Activity's background become black when i entered in activity or onLongPress of Listview

I am trying to implement one ListView in activity. In my XML there is a ListView to fill that ListView data I have invoked one WebService in AsynkTask. I have used BaseAdapter to set that ListView. Now, Whenever I came on that activity the background becomes black for fraction seconds of time and than disappear. Same things happened when I longpress on ListView. The screen shot had attached with this question as well as following are the code that I have implemented.

The dialog box is trigered from an adapter of a listview and that's the adapter's code:
holder.replay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
InstantTextBoxDialog exampleDialog=new InstantTextBoxDialog();
exampleDialog.show(((Activity) activity).getFragmentManager(),"sadsdadsaadassd");
}
});
But till now nothing shows except the buttons and no listview

How do I replace my popupmenu code with ListPopupWindow?

Currently , I am programatically creating a popupmenu which displays a list of floors and a title. However, changing the background color of just the title and adding a close button to title is turning out to be a nightmare.
I want to replace this popupmenu with a list popup window so I can add an XML file with background attribute for the title with a black color as the background and a close button on the right and white background for items in the menu. Is there a way I can achieve this with list popup window? Here's my code for that:
private void floorMenu(ImageView btnFloorMenu){
MapData data = new MapDao(MyPlugin.mapId);
final List<Floor> flList = dao.getFloors();
// set popupMenu
final PopupMenu floorsPm = new PopupMenu(MapViewActivity.this,btnFloorMenu);
MenuItem titleItem = floorsPm.getMenu().add(Menu.NONE, Menu.NONE, Menu.NONE, "Floors");
int i = 1;
for(Floor fl : flList)
{
floorsPm.getMenu().add(Menu.NONE, i,i, fl.getName());
if(i>3)
break;
i++;
}
// add popup listener
floorsPm.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
// onClick
#Override
public boolean onMenuItemClick(MenuItem item){
// get floorname
int flOrder = item.getOrder();
if(flOrder == Menu.NONE )
return true;
flOrder--;
final String floorId = flList.get(flOrder).getMapId();
// set camera to floor
runOnUiThread(new Runnable() {
#Override
public void run() {
floorsPm.dismiss();
mapFragment.getMapManager().setCameraLayer(floorId, false);
Log.d(TAG, "post cameraLayer set");
changedSteps = true;
pauseNav();
}
});
return true;
}
});
floorsPm.show();
}

Here is my example to create show a ListPopupWindow
First, create layout item_list_popup_window for each item of ListPopupWindow
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#e4e4e4"
android:paddingTop="1dp"
android:orientation="horizontal">
<TextView
android:id="#+id/text_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1" />
<Button
android:id="#+id/button_delete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Delete" />
</LinearLayout>
Second, create an Adapter for your ListPopupWindow like
public class ListPopupWindowAdapter extends BaseAdapter{
private Activity mActivity;
private List<String> mDataSource = new ArrayList<>();
private LayoutInflater layoutInflater;
private OnClickDeleteButtonListener clickDeleteButtonListener;
ListPopupWindowAdapter(Activity activity, List<String> dataSource, #NonNull OnClickDeleteButtonListener clickDeleteButtonListener){
this.mActivity = activity;
this.mDataSource = dataSource;
layoutInflater = mActivity.getLayoutInflater();
this.clickDeleteButtonListener = clickDeleteButtonListener;
}
#Override
public int getCount() {
return mDataSource.size();
}
#Override
public String getItem(int position) {
return mDataSource.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if(convertView == null){
holder = new ViewHolder();
convertView = layoutInflater.inflate(R.layout.item_list_popup_window, null);
holder.tvTitle = (TextView) convertView.findViewById(R.id.text_title);
holder.btnDelete = (Button) convertView.findViewById(R.id.button_delete);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
// bind data
holder.tvTitle.setText(getItem(position));
holder.btnDelete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
clickDeleteButtonListener.onClickDeleteButton(position);
}
});
return convertView;
}
public class ViewHolder{
private TextView tvTitle;
private Button btnDelete;
}
// interface to return callback to activity
public interface OnClickDeleteButtonListener{
void onClickDeleteButton(int position);
}
}
Third, You create a function for create and show ListPopupWindow
private void showListPopupWindow(View anchorView) {
final ListPopupWindow listPopupWindow = new ListPopupWindow(this);
listPopupWindow.setWidth(600);
List<String> sampleData = new ArrayList<>();
sampleData.add("A");
sampleData.add("B");
sampleData.add("CCCCCCCCCCCCCC");
sampleData.add("D");
sampleData.add("EEEEEEEEE");
listPopupWindow.setAnchorView(anchorView);
ListPopupWindowAdapter listPopupWindowAdapter = new ListPopupWindowAdapter(this, sampleData, new ListPopupWindowAdapter.OnClickDeleteButtonListener() {
#Override
public void onClickDeleteButton(int position) {
Toast.makeText(MainActivity.this, "Click delete " + position, Toast.LENGTH_SHORT).show();
listPopupWindow.dismiss();
}
});
listPopupWindow.setAdapter(listPopupWindowAdapter);
listPopupWindow.show();
}
Finally, you can show the ListPopupWindow by
showListPopupWindow(v);
for example, if you want to show it when click button
anyButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showListPopupWindow(v);
}
});
Full Demo is here

Please Try this code, Maybe you wont like this
private void floorMenu(ImageView btnFloorMenu){
final Dialog customDialog = new Dialog(this);
customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
customDialog.setContentView(R.layout.item_dialog_coustom_design);

Android - SetOnItemClickListener doesn't work

I know here we have a lot of questions like mine, but I don't know why none works for me.
My objective: I have an AlertDialog with a ListView with a check box in each row, I can select some of the items, and I wish to make an ArrayList with the elements selected.
For that reason, I'm calling the SetOnclickListener, I put a Log inside the method, but does nothing.
I tried with focusable and clickable almost everywhere, but my Log doesn't appear.
Here My alert Dialog
private void callAdditionalDialog() {
LayoutInflater layoutInflater = LayoutInflater.from(ConfigProductActivity.this);
final View additionalView = layoutInflater.inflate(R.layout.dialog_additional, null);
additionalView.setFocusable(true);
// set the custom dialog components - text, buttons, accountants
TextView titleDialog = (TextView) additionalView.findViewById(R.id.title_additional);
titleDialog.setTypeface(boldFont);
Button buttonAccept = (Button) additionalView.findViewById(R.id.button_accept);
buttonAccept.setTypeface(boldFont);
Button buttonCancel = (Button) additionalView.findViewById(R.id.button_cancel);
buttonCancel.setTypeface(boldFont);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ConfigProductActivity.this);
alertDialogBuilder.setView(additionalView);
final AlertDialog alertD = alertDialogBuilder.create();
alertD.setCanceledOnTouchOutside(false);
//Fill object of additional
final ListView additionalListView = (ListView) additionalView.findViewById(R.id.list_additional);
TextView additionalNotFound = (TextView) additionalView.findViewById(R.id.additional_not_found);
if (!withoutModifiers){
additionalAdapter = new AdditionalAdapter(ConfigProductActivity.this, additionalList);
additionalListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
additionalListView.setAdapter(additionalAdapter);
final ArrayList<ModifierEntity> modifierList = new ArrayList<ModifierEntity>();
additionalListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,
View view, int position, long id) {
Object modifier = additionalListView.getAdapter().getItem(position).toString();
Log.d(TAG, "SOMETHIIIIING");
}
});
}
else{
additionalListView.setVisibility(View.GONE);
additionalNotFound.setVisibility(View.VISIBLE);
additionalNotFound.setTypeface(font);
buttonCancel.setVisibility(View.GONE);
}
//End of fill object of additional
buttonCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
buttonAccept.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//additional.setText(additionalAdapter.getCount());
additionalBox.setEnabled(true);
alertD.dismiss();
}
});
alertD.show();
}
Here my adapter:
public class AdditionalAdapter extends ArrayAdapter {
private static String TAG = AdditionalAdapter.class.getName();
private List<ModifierEntity> originalData = null;
private ConfigProductActivity activity;
private Typeface font;
private Typeface boldFont;
private static ModifierEntity modifier;
public AdditionalAdapter (ConfigProductActivity activity, List<ModifierEntity> listArray){
super(activity, R.layout.additional_item);
this.activity = activity;
this.originalData = listArray ;
font = Typeface.createFromAsset(activity.getAssets(),"HelveticaNeueThn.ttf");
boldFont = Typeface.createFromAsset(activity.getAssets(), "avgardm.ttf");
}
public static class Row
{
public TextView labelName;
public TextView labelPrice;
public CheckBox check;
}
#Override
public int getCount() {
return originalData.size();
}
#Override
public ModifierEntity getItem(int position) {
return originalData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final int colorFont = activity.getResources().getColor(R.color.brown_tataki);
final Row holder;
View rowView = convertView;
// reuse views
if (convertView == null) {
holder = new Row();
LayoutInflater inflater = LayoutInflater.from(activity);
rowView = inflater.inflate(R.layout.additional_item, null);
rowView.setClickable(true);
//rowView.setFocusable(false);
// configure view holder
holder.labelName = (TextView) rowView.findViewById(R.id.additional_name);
holder.labelPrice = (TextView) rowView.findViewById(R.id.additional_price);
holder.check = (CheckBox) rowView.findViewById(R.id.additional_check);
rowView.setTag(holder);
}
else {
holder = (Row) convertView.getTag();
// rowView.setClickable(true);
}
final ModifierEntity itm = originalData.get(position);
holder.labelName.setText(itm.getModifier_name());
holder.labelName.setTypeface(font);
holder.labelName.setTextColor(colorFont);
holder.labelPrice.setText(GlobalParameters.CURRENCY.concat(String.valueOf(itm.getModifier_cost())));
holder.labelPrice.setTypeface(boldFont);
holder.labelPrice.setTextColor(colorFont);
return rowView;
}
}

Using interfaces I can solve my problem, this link provided me the solution, and bassically consist in create an interface and implement in my activity.
Like this:
1.- Interface
public interface MyListener {
void folderClicked();
}
2.- Implements the interface in the activity
public class ActivityA extends Activity implements MyListener
3.- You will have to auto override the method folderClicked it will look like this:
#Override
protected void folderClicked() {
// Do your stuff here.
}
4.- Send the activity listener to the adapter with constructor like this:
MyAdpater adapter = new MyAdpater(ActivityA.this);
5.- Your adapter class your code should be like this:
public class TimeLineAdapter extends BaseAdapter {
private MyListener mListener;
public TimeLineAdapter(MyListener listener) {
super();
mListener = listener;
}
holder.iconImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mListener.onFolderClicked()
//code to do stuff when the image is clicked
}
