Hope this will help

you can Implement OnItemSelected in the spinner and do the things what you want.
categories.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
if(arraySpinner!=null && arraySpinner[position].equalIgnoreCase("Other")){
// your code here
}
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}
});

Item selection in spinner doesn't detect in MyOnItemSelectedListener

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.

android:opening new intent in spinner view

I am making an app in which i have to use spinner view to show some items and i want on click of item it should go to that page. i want when i clicke on spanish i should go to spanish pageMy code is as follows.
System.out.println("test1");
Spinner spinner = (Spinner) findViewById(R.id.spinner);
System.out.println("test2");
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.models, android.R.layout.simple_spinner_item);
System.out.println("test3");
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
System.out.println("test3");
spinner.setAdapter(adapter);
System.out.println("test4");
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}

You have to write intent in your onItemSelected method for page/activity which you want to open.
and set position for that.
#Override
public void onItemSelected(AdapterView<?> adaptername, View view,int position, long id)
{
if(position==0)
{
// write the intent for page which you want to open
}
if(position==1)
{
//
}
.
.
.
and same
}

multiple spinner's simple doubts

Im new to android. i have tried to built an application which has 2 spinner...
i have few doubts to clear before going deep to my application..
please give brief answer to my question...
is it possible to have 2 spinners in one view?
can i add setOnItemSelectedListener(this) for both?
if yes, how could i know which option is selected on both the spinners? like spinner.getSelectedItemPosition(); on both the spinners?
waiting for ur valuable replies. reference materials are also appreciable

Yes, you can have multiple spinner's that can be managed by single listener or you can have seperate Listener for each.
For Single Listener you can do something like this,
Set the Listener
spinner1.setOnItemSelectedListener(this);
spinner2.setOnItemSelectedListener(this);
Then you can use onItemSelected to get perform the action related to the spinner's.
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position,long arg3)
{
int id = parent.getId();
switch (id)
{
case R.id.spinner1:
// your stuff here
break;
case R.id.spinner2:
// your stuff here
break;
}

Check this:
Spinner spinner0, spinner1, spinner2;
TextView textView0, textView1, textView2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView0 = (TextView) findViewById(R.id.text0);
spinner0 = (Spinner) findViewById(R.id.spinner0);
ArrayAdapter<String> adapter0 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, text0);
adapter0.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner0.setAdapter(adapter0);
spinner0.setOnItemSelectedListener(onItemSelectedListener0);
textView1 = (TextView) findViewById(R.id.text1);
spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, text1);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
spinner1.setSelection(0,false); //make sure only one listener is
//active in the onCreate method by setting the other listener as false
spinner1.setOnItemSelectedListener(onItemSelectedListener1);
textView2 = (TextView) findViewById(R.id.text2);
spinner2 = (Spinner) findViewById(R.id.spinner2);
MySpinnerAdapter adapter2 = new MySpinnerAdapter(MainActivity.this, android.R.layout.simple_spinner_item, obj2);
//adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner2.setAdapter(adapter2);
spinner2.setSelection(0,false);
spinner2.setOnItemSelectedListener(onItemSelectedListener2);
}
OnItemSelectedListener onItemSelectedListener0 = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//do your stuff spinner0
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
OnItemSelectedListener onItemSelectedListener1 = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//do your stuff spinner1
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
OnItemSelectedListener onItemSelectedListener2 = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//do your stuff spinner2
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
}

If the reference of two spinners are different(which will be , if you are using 2 spinners) , give different IDs for them and you can uniquely identify them, Yes you can set click listener to both of them individually.
spinner.setOnItemSelectedListener(new OnItemSelectedListener() { ... } );
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() { ... } );

yes
yes
spinner1.getSelectedItemPosition(), spinner2.getSelectedItemPosition()
