I've created three Spinners with certain list of values. I store each Spinner's selection value in a variable. The problem is when I go to the next page I lose my variables. What should I do?
public class TabOneActivity extends Activity implements OnItemSelectedListener{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabone);
// Spinner element
Spinner spinner = (Spinner) findViewById(R.id.fudtaste);

spinner.setOnItemSelectedListener(this);
// Spinner Drop down elements
List<String> categories = new ArrayList<String>();
categories.add(" Chineese");
categories.add(" Fast Food");
categories.add(" Traditional");
categories.add(" Mixed");
categories.add(" Favourites");
categories.add(" Combo Items");
//Toast.makeText(getApplicationContext(),newPos1,Toast.LENGTH_LONG).show();
// System.out.println(str + "sarath" );
Spinner spinner2 = (Spinner) findViewById(R.id.foodmoney);
// Spinner click listener
spinner2.setOnItemSelectedListener(this);
// Spinner Drop down elements
List<String> categories2 = new ArrayList<String>();
categories2.add(" Fast Food");
categories2.add(" Pub Food");

System.out.println(newPos2 + "sarath" );

Try below.
check the onClickListener of button which will decide which activity to open.
Spinner spinner1;
Spinner spinner2;

iller is my First List and I set this list my firs spinner then I implements onItemSelected method for this spinner. In this method you can add your second spinner with difrent List.
Spinner spinner = (Spinner) findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(this);
List<String> iller = new ArrayList<String>();
iller.add("İl Seçiniz..");
iller.add("Antalya");
iller.add("Burdur");
iller.add("Bursa");
iller.add("Balıkesir");
iller.add("Giresun");
iller.add("İstanbul");
ArrayAdapter<String> illerAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, iller);
illerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(illerAdapter);
spinner2 = (Spinner) findViewById(R.id.spinner2);
spinner2.setVisibility(View.INVISIBLE);
editText = (EditText) findViewById(R.id.editText);
editText.setVisibility(View.INVISIBLE);
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
int itemId = (int) id;
if (itemId == 1) {
iller.remove("İl Seçiniz..");
antalyaİlceler = new ArrayList<String>();
antalyaİlceler.add("İlçe Seçiniz..");

I have 2 spinners in an activity.
Based on the selection of one item in spinner1, relevant data should be loaded in spinner2. Consider spinner1 has data related to country and spinner2 has data related to state.
I should be able to get this done once the activity is created and if the user changes the selection in spinner1.
But I am stuck with populating the spinner2 data based on the saved value of spinner1.
I am calling spinner1.setSelection(indexSaved) but since I am only loading spinner2 in the onItemSelectedOf of spinner1, setSelection of spinner1 is not firing the onItemSelected.
Please let me know how I can achieve this.
I have done same thing in my project without any problem:
Below is code may be it help you:
On Create Method filled state list:

{
states = manage_states.fetchAllStates(getApplicationContext());
//add new element for select name
states.add(0,new RowItem("-1", "Select State"));
String[] spinnerArray = new String[states.size()];
for(int i= 0;i<states.size();i++)
{
spinnerArray[i] = states.get(i).getName();
}

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.
how to disable a spinner based on another spinner. For sample, when I choose first spinner value is "Yes" then the second spinner is enable also when I choose first spinner value is "No" then the second spinner is disable.
Thanks
Try this:
final Spinner sp1 = (Spinner) findViewById(R.id.spinner1);
final Spinner sp2 = (Spinner) findViewById(R.id.spinner2);
ArrayAdapter<String> data = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, first);
ArrayAdapter<String> data2 = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, second);
sp1.setAdapter(data);
sp2.setAdapter(data2);
sp1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
String text = sp1.getSelectedItem().toString();
if (text.equals("No")) {
sp2.setEnabled(false);
} else {
sp2.setEnabled(true);
}
}
#Override

// TODO Auto-generated method stub
