Hi I am creating a list of spinners dynamically based on a user choice. Here I am also implementing OnItemSelectedListener for each of the spinners, since there are multiple spinners I want to know which spinner's method is currently being accessed. Here's the code,
for (int i = 0; i < count; i++) {
ArrayList<String> spinnerArray = new ArrayList<String>();
spinnerArray.add("one");
spinnerArray.add("two");
spinnerArray.add("three");
spinnerArray.add("four");
spinnerArray.add("five");
Spinner spinner = new Spinner(this);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
Object item = parent.getItemAtPosition(position);
Log.d("vij-debug", "selector1 no is " + item);
Log.d("vij-debug", "selector1 id is"+ view.getId());
//medicineArray1[i][1]=(String)item;
// here I want to access the iteration value i
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_dropdown_item,
spinnerArray);
spinner.setAdapter(spinnerArrayAdapter);
Can anyone suggest a suitable solution?
Set the Spinner's tag to i upon creation, then retrieve it from the AdapterView<?> parent parameter in onItemSelected().
Spinner spinner = new Spinner(this);
spinner.setTag(i);
...
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
int spinnerNumber = parent.getTag();
}
...
}
);
you could use a List and store your spinner there. in your for loop
//inside for loop
List<Spinner> spinnerList=new ArrayList<Spinner>();
Spinner spinner = new Spinner(this);
spinnerlist.add(spinner);
//end
//outside for loop
for(int i=0;i<spinnerList.size();i++){
setListenerToSpinner(spinnerList.get(i));
}
//end
//function
public void setListenerToSpinner(Spinner spinner){
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
Object item = parent.getItemAtPosition(position);
Log.d("vij-debug", "selector1 no is " + item);
Log.d("vij-debug", "selector1 id is"+ view.getId());
//medicineArray1[i][1]=(String)item;
// here I want to access the iteration value i
}
}

I want to get information using putExtra() on another page and I can do it, but my only problem is always the default value the first value sample_array but i want to by default classDayIntent value is displayed in spinner
tip: The putExtra() received in Spinner is there
First Activity:
Intent intent = new Intent();
intent.putExtra("className" , className);
intent.putExtra("uniName" , uniName);
intent.putExtra("classDay" , classDay);
intent.setClass(context , AddNewClass.class);
context.startActivity(intent);
Second Activity:
Spinner spinner = (Spinner)findViewById(R.id.spinnerDay);
String className = getIntent().getStringExtra("className");
String uniName = getIntent().getStringExtra("uniName");
String classDayInent = getIntent().getStringExtra("classDay"); // How To Display classDayInent In Spinner....
className_EditeText.setText(className);
uniName_EditeText.setText(uniName);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this , R.array.sample_array , android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String classDay = parent.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Strings:
<resources>
<string name="app_name">ClassManager</string>
<string-array name="sample_array">
<item>شنبه</item>
<item>یکشنبه</item>
<item>دوشنبه</item>
<item>سه شنبه</item>
<item>چهارشنبه</item>
<item>پنجشنبه</item>
<item>جمعه</item>
</string-array>
you can use add function of adapter.
since CharSequence is an interface, and the String class implements CharSequence so you can directly add string to adapter
adapter.add(classDayInent);
spinner.setAdapter(adapter);
Another issue is , createFromResources creates a immutable list mean it cannot add more items.
Solution : create your own adapter with mutable list
List<String> list = new ArrayList<>(Arrays.asList(getResources().getStringArray(R.array.sample_array)));
ArrayAdapter<String> adapter = new ArrayAdapter<>(this , android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
list.add(0,classDayIntent);// to add received element at first position to display
spinner.setAdapter(adapter);
You can get your xml arraylist and then add to that:
List<String> ar = new LinkedList<String>(Arrays.asList(getResources().getStringArray(R.array.sample_array)));
ar.add("test");
i found correct answer :
String classDayInent = getIntent().getStringExtra("classDay");
List<String> list = new ArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.sample_array)));
ArrayAdapter<String> adapter = new ArrayAdapter<>(this , android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
//find classDayIntent from List For get Position To Display
for (int i = 0; i < list.size(); i++)
{
if (classDayIntent.equals(list.get(i)))
{
spinner.setSelection(i);
}
}
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
classDay = parent.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
I'm developing a e-com app. I'm trying to create dynamic spinner. Spinner is dependent upon product attributes. I'm able to create spinners also mapped data on them but I want to get all spinners selected item whenever a spinner change its data so I can match to correct variant of product.
Here is my code snippet
final List<Attribute> attributes = product_.getAttributes();
for (i = 0; i < attributes.size(); i++) {
ArrayList<String> spinnerArray = (ArrayList<String>) attributes.get(i).getOptions();
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, spinnerArray);
Spinner spinner = new Spinner(getActivity());
spinner.setAdapter(spinnerArrayAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
dynamicProductProperties.addView(spinner);
}
First, you need to set same instance of OnItemSelectListener to your all spinners. Let your activity or fragment implement OnItemSelectListener then call spinner.setOnItemSelectListener(this);
In onItemSelected method you can run this code to have selecteds.
ArrayList<String> selectedList = new ArrayList();
for (int i = 0; i < dynamicProductProperties.getChildCount(); i++) {
View view = dynamicProductProperties.getChildAt(i);
if (view instanceof Spinner){
String selected = (String) ((Spinner) view).getSelectedItem();
selectedList.add(TextUtils.isEmpty(selected) ? "" : selected);
}
}
Good luck

I have activity with 3 spinners and selection of 1st spinner is related to 2nd and 2nd selection is related to the 3rd, so I have the spinner code one inside one.
CrustSp, SizeSp and extraDescriptionOneSP are the 3 spinners I have. I have loaded the items to the Spinners and I can select a value as well. But my problem is whenever i made a selection in CrustSp and SizeSp doesn't show in MyOnItemSelectedListener(). But if I made a selection in extraDescriptionOneSP it shows inside MyOnItemSelectedListener().
I can't figure where I have gone wrong, anyone can point out where I have gone wrong it will be really helpful.
This the code
crust = Utils.removeDuplicatesFromList(crust);
ArrayAdapter<String> dataAdapterCru = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, crust);
dataAdapterCru
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
crustSP.setAdapter(dataAdapterCru);
crustSP.setOnItemSelectedListener(new MyOnItemSelectedListener(
ActivityPizzaCustomize.this) {
public void onNothingSelected(AdapterView<?> arg0) {
}
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
String crustSelectedItem = crustSP.getSelectedItem()
.toString();
List<String> resultSizes = getFilteredSizes(crustSelectedItem);
ArrayAdapter<String> dataAdapterDes = new ArrayAdapter<String>(
ActivityPizzaCustomize.this,
android.R.layout.simple_spinner_item,
resultSizes);
dataAdapterDes
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sizeSP.setAdapter(dataAdapterDes);
sizeSP.setOnItemSelectedListener(new MyOnItemSelectedListener(
ActivityPizzaCustomize.this) {
public void onNothingSelected(AdapterView<?> arg0) {
}
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
String sizeSelectedItem = sizeSP
.getSelectedItem().toString();
List<String> resultTopping = getFilteredToppings(sizeSelectedItem);
extraDescriptionOneSP
.setOnItemSelectedListener(new MyOnItemSelectedListener(
ActivityPizzaCustomize.this));
ArrayAdapter<String> dataAdapterExtraDesOne = new ArrayAdapter<String>(
ActivityPizzaCustomize.this,
android.R.layout.simple_spinner_item,
resultTopping);
dataAdapterExtraDesOne
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
extraDescriptionOneSP
.setAdapter(dataAdapterExtraDesOne);
extraDescriptionOneSP
.setAdapter(new NothingSelectedSpinnerAdapter(
dataAdapterExtraDesOne,
R.layout.contact_spinner_row_nothing_selected,
ActivityPizzaCustomize.this));
}
});
}
});
MyOnItemSelectedListener method,
public class MyOnItemSelectedListener implements OnItemSelectedListener {
Activity activity;
String StrOneSPPosition;
public MyOnItemSelectedListener(Activity p_activity) {
activity = p_activity;
}
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
// check which spinner triggered the listener
switch (parent.getId()) {
case R.id.sp_crust: {
String StrCrustSPPosition = String.valueOf(crustSP
.getSelectedItemPosition());
System.out.println("crust = " + StrCrustSPPosition);
System.out.println("crust = " + position);
CrustSPPosition = Integer.parseInt(StrCrustSPPosition);
}
I don't see you using the selected position to determine the data for next spinner. BTW you should not make new adapter for each selection, instead reuse the once made adapter.
I used two spinners, country and state which i get from web-service.
i get Country in first web-service then i should pass selected country from spinner to the second web-service, How can i call the dependent Spinner in Web-service ?
Give me the example,
Thanks.
First Spinner
int i = 0;
String[] stringArray = new String[List.length];
for (i = 0; i < List.length; i++) {
stringArray[i] = Arrays.asList(List[i].Country);
}
Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, stringArray);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
I had the same query some days back I guess this will solve your problem.
Add this after your spinner1 code
// here onitemselected call your second method
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
statewebservice((String) parent.getItemAtPosition(pos));
}
And for state spinner in your second web service
int i = 0;
String[] stringArray2 = new String[List2.length];
for (i = 0; i < personList1.length; i++) {
stringArray2[i] = Arrays.asList(List2[i].State);
}
Spinner spinner2 = (Spinner) findViewById(R.id.spinner2);
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, stringArray2);
adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner2.setAdapter(adapter2);
spinner2.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(final AdapterView<?> parent,
View view, final int pos1, long id) {
//************Code after selecting second spinner ***********
}
});
}
int numberofSpinner = TransportResult.Transfers.size();
Spinner spin=null;
for(int i=0;i<numberofSpinner;i++)
{
spin = new Spinner(this);
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT,1);
spinLayout.addView(spin,p);
spin.setId(i);
Transfer transfer = TransportResult.Transfers.get(i);
ArrayList<CharSequence> s = new ArrayList<CharSequence>();
for( Line l : transfer.TransferLine)
{
s.add(l.ShortName+" - "+Helper.FindTransportTypeText(l.LineType));
}
adapter = new ArrayAdapter<CharSequence>(this,android.R.layout.simple_spinner_item,s);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(adapter);
}
spin.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
if(parent.getId()==0){
System.out.println("spin 1 is called");
String str = (String)parent.getSelectedItem();
}else if(parent.getId()==1){
System.out.println("spin 2 is called");
String str = (String)parent.getSelectedItem();
}
}
public void onNothingSelected(AdapterView<?> arg0) {
}
});
If the number of spinner is more than 1, only the last spinner is triggered. For example; i have 3 spinner on screen, when i select the item of first or second spinner, the listener is never triggered. Only the third spinner triggers the listener. How can i solve that?
Thank you
UPDATE
when you use more than one spinner then setid for each spinner spin.setId(int) .and you can check id in OnItemSelected method. Mind that when you set OnitemSelected first time onItemSelected is called.
spin.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
if(parent.getId()==1){
System.out.println("spin 1 is called");
String str = (String)parent.getSelectedItem();
}else if(parent.getId()==2){
System.out.println("spin 2 is called");
String str = (String)parent.getSelectedItem();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
