How to add 'select one' to a spinner, which gets data after api call

I have a spinner which populates data after an API call. I need to add an item that says "select one" as a first item in spinner. This item should not be able to be selected. I tried several ways online, but not able to implement it in my code since the array is filled after the api call and couldn't figure out a correct way to add "select one" item to that array.. Could anyone tell me how to do this in my code?
public void TEMPLATE_PARSE(JSONArray array) {
TemplateArrayList = new ArrayList<>();
TemplateNames = new ArrayList<String>();
for (int i = 0; i < array.length(); i++) {
JSONObject json = null;
try {
json = array.getJSONObject(i);
ModelTemplate GetTemplateDataModel = new ModelTemplate();
GetTemplateDataModel.setTemplateID(json.getInt("TemplateID"));
GetTemplateDataModel.setTemplateText(json.getString("TemplateText"));
TemplateArrayList.add(GetTemplateDataModel);
TemplateNames.add(TemplateArrayList.get(i).getTemplateText().toString());
} catch (JSONException e) {
e.printStackTrace();
}
} // Close for loop here
if (array.length() != 0) {
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, simple_spinner_item, TemplateNames);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down view
spinTemplate.setAdapter(spinnerArrayAdapter);
spinTemplate.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.i("ssssmIsSpinnerFirstCall",mIsSpinnerFirstCall.toString());
if(!mIsSpinnerFirstCall) {
selectedTemplateID = TemplateArrayList.get(position).getTemplateID();
String selectedTemplateText = TemplateArrayList.get(position).getTemplateText();
editText.setText(selectedTemplateText);
saveInSp("selectedTemplateID", String.valueOf(selectedTemplateID));
templateSelected = true;
}
mIsSpinnerFirstCall = false;
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
}

First add Select One at position 0 to TemplateNames and then create adapter and set it to Spinner
TemplateNames.add(0, "Select One");
And then inside onItemSelected, check selected position and do whatever you want.
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if(position == 0)
// Skip or show validation message if you want
else {
// Do your actual task here
...
selectedTemplateID = TemplateArrayList.get(position - 1).getTemplateID();
String selectedTemplateText = TemplateArrayList.get(position - 1).getTemplateText();
...
}
}

Add Multiple Dynamic Spinner Views in Android Activity,Not Loading Selected Spinner Data In second Spinner

In My application i am Having Dynamic Spinners.
Totally 2 Spinners are there in a Method,Both are dependent(SPinner1 ,Spinner2).
I can call that method multiple Times.
Spinner Data Loading from Local database.
Problem:
i called that method twice So activity Shown Totally 4 Spinners.
1a.spinner1
1b.SPinner2
2a.Spinner1
2b.Spinner2
Based on 3rd Spinner what i Selected , 4th Spinner data is loading perfectly.
but based on 1st Spinner Selected item data Not showing in 2nd Spinner, because last iteration data(3rd and 4th spinner)only stored in String Array.
Please Help me to Solve this. show data in all the spinners.

I haven't not tested this. Hope it help you.

before adding views to mContainerView.addView(rowView123);
first remove the previous child views.
//snippet.
//remove all views
mContainerView.removeAllViews();
//add new views
mContainerView.addView(rowView123);

How to add the label of item when pressed and delete it when again pressed with item separator(,)?

[Edited]
Something like this..
when pressed the item labels are added with comma if there is item more than two[and when pressed again deletes the item labels with comma
this is what ive done so far
Note SeatP is a textView and seat_n is selected item label from the list
List<Seats> seatsList;
GridView myGrid;
MyGridAdapter adapter;
TextView seatlabel,pricelabel;
ImageView im;
String st,seat_n,seatp;
myGrid = (GridView) findViewById(R.id.grid);
seatlabel = (TextView) findViewById(R.id.labelSeat);
pricelabel = (TextView) findViewById(R.id.labelPrice);
public void updateMessage(){
adapter = new MyGridAdapter(getApplicationContext(),R.layout.seat_item,seatsList);
myGrid.setAdapter(adapter);
myGrid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
st = seatsList.get(position).getStatus();
seat_n = seatsList.get(position).getSeat_no();
p = seatsList.get(position).getPrice();
Log.d("price: ", p + "");
//Log.d("status: ", seat_n + "");
im = (ImageView) view.findViewById(R.id.seat1);
if (st.equalsIgnoreCase("available")) {
im.setImageResource(R.drawable.seat);
myStatus = true;
seatsList.get(position).setStatus("select");
Log.d("status 1: ",myStatus+"");
if (seatp.length()>1){
seatp = seatp+"," + seat_n;
}else {
seatp = seatp+ seat_n;
}
pr = pr+p;
seatlabel.setText(seatp.trim());
pricelabel.setText(Integer.toString(pr));
}
if(st.equalsIgnoreCase("select")) {
// Toast.makeText(getApplicationContext(), "seat: " + seatsList.get(position).getStatus(), Toast.LENGTH_SHORT).show();
im.setImageResource(R.drawable.seat_avv);
seatsList.get(position).setStatus("available");
pr = pr-p;
pricelabel.setText(Integer.toString(pr));
seatp= seatlabel.getText().toString();
//Log.d("seatlabel: ",ab);
//seatp= seatp.replace(seat_n, "");
if(seatp.length()>=5){
seatp= seatp.replace(","+seat_n, "");
}else {
seatp= seatp.replace(seat_n+",", "");
}
Log.d("seatp Length: ",seatp.length()+"");
/*if(seatp.length()>2){
seatp= seatp.replace(", "+seat_n, "");

}
}
});
}
Here the logic is good for 2nd or more items But didn't worked for the first item

if i understand you well, you can use ArrayList
call addOrRemoveItem() on click at labels, passing the text you need to add
and when save or next or whatever is clicked call getAsCommaSeparator()
ArrayList<String> items = new ArrayList<>();
public void addOrRemoveItem(String item){
if(items.contains(item)){
items.remove(item);
}else{
items.add(item);
}
}
public String getAsCommaSeparator(){
return android.text.TextUtils.join(",",items);
}

Undo actions in a Listview - onitemclicklistener

this is my code; basically, it is a listview with multiple choice that add a number to a score (textview) when its clicked. My problem is that i would like the number be added to the score when the item is selected in the listview, and removed when the item is deselected. With my code each time that you click an item, the number is added to the score.
public class MainActivity extends Activity {
ListView myList;
TextView tv1;
String[] listContent = {
"Add 2 to total",
"Add 3 to total",
"Add 1 to total",
"Add 5 to total",
};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myList = (ListView) findViewById(R.id.listView1);
tv1 = (TextView) findViewById(R.id.textView);
final int[] counter = {0};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, listContent);
myList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
myList.setAdapter(adapter);
myList.setOnItemClickListener(new OnItemClickListener() {
private String[] listview_array2 = {"2", "3", "1", "5"};
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
if (myList.isItemChecked(position)) {
String name = this.listview_array2[position];
int counter2 = Integer.parseInt(name);
counter[0] = counter[0] + counter2;
tv1.setText("Total " + counter[0]);
} else {
}
}
});
}
}
I have thought that maybe changing to setOnItemSelected instead of ItemClicked, but I am not sure.
Hope I have explain myself properly and you can help me.
Thank you in advanced.

Try with OnItemClickListener with a Boolean for selection/deselection.
Hope this will work

You can do that through your code.
Maintain a flag in the list of your values like List list;
Values is a model containing the number and a flag.
If a item is clicked, set the flag true and do your calculations.
If already clicked item is clicked again, you just need to check the flag.
if(list.getposition(position).isItemClickd){
// Decrease that value from total
// list.getposition(position).isItemClickd = false;
} else{
// list.getposition(position).isItemClickd = true;
// total = total+prevValue;
}

I finally made it in a easy way!!!
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
if (myList.isItemChecked(position)) {
String name = this.listview_array2[position];
int counter2 = Integer.parseInt(name);
counter[0] = counter[0] + counter2;
tv1.setText("Total " + counter[0]);
I add in "else" the same action than in "if", but subtracting the number

Android ListView with Multiselect not deselecting items

I have a multi-select listview where I want to keep track of what the user has selected and what they have deselected. When a user clicks on a list item, I add the clicked items into an ArrayList and when they click it again I remove the item from the ArrayList. The issue is that the deselect operation(when a user clicks on an item already clicked on earlier) is adding into the ArrayList again instead of removing.
Below is the code for onListItemClick for that activity:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CheckBox checkBox = (CheckBox) view.findViewById(R.id.chk_forEasyPayListItem);
int stringPos = 0;
selectedBiller = billerNamesArray[position];
selectedBillerAccountNumber = billerAccountsArray[position];
selectedBillerBalance = billerToPayBalances[position];
SparseBooleanArray sparseBooleanArray = lstPayMyBills.getCheckedItemPositions();
if (sparseBooleanArray != null && sparseBooleanArray.size() > 0) {
for (int index = 0; index < sparseBooleanArray.size(); index++) {
if (sparseBooleanArray.valueAt(index)) {
lstPayMyBills.setItemChecked(sparseBooleanArray.keyAt(index), true);
checkBox.setChecked(true);
selectedItems.add(new PayMyBillsListItemModel(position, selectedBiller, selectedBillerAccountNumber, selectedBillerBalance));
adapter.notifyDataSetChanged();
Toast.makeText(getApplicationContext(), "Array size is " + selectedItems.size(), Toast.LENGTH_LONG).show();
} else {
lstPayMyBills.setItemChecked(sparseBooleanArray.keyAt(index), false);
checkBox.setChecked(false);
//selectedItems.remove(new PayMyBillsListItemModel(position, selectedBiller, selectedBillerAccountNumber, selectedBillerBalance));
}
}
} else {
for (int index = 0; index < lstPayMyBills.getCount(); index++) {
lstPayMyBills.setItemChecked(index, true);
checkBox.setChecked(false);
selectedItems.remove(new PayMyBillsListItemModel(position, selectedBiller, selectedBillerAccountNumber, selectedBillerBalance));
adapter.notifyDataSetChanged();
Toast.makeText(getApplicationContext(), "Array size is " + selectedItems.size(), Toast.LENGTH_LONG).show();
}
}
}

I think your problem may be that you are creating a new object to remove. if you had a list of "A", "B", "C", "D", "B" and you called remove("B") your list would be:
"A", "C", "D", "B" (removes first occurrence). I think you would have to look for the object in your selected list which matches the one deselected then remove that.
I am not sure on the behavior removing a new object?
