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
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

I am new to android,and in this code i have two spinners and based on the values selected,different layouts should open accordingly. Im stuck with what logic should i use to open different layouts, inside the OnItemSelected for the spinner.Say i have 5 items in spinner and i have 5 different layouts for each item.So how should i do??
Any help or ideas would be much appreciated. Thanks in advance.

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");

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>();

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:

{
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 2 spinners in my activity as category and sub-category.
When i choose some value from category spinner
I want to display its related values/data in sub-category spinner.
How can i perform this?
public class SellActivity extends Activity {
private Spinner spinner1, spinner2;
private String selectedOption;
List<String> addItemList = new ArrayList<String>();
String[] elCat = new String[] {"Mobile", "Television", "Computers","Home Appliances","Games","Others"};
String[] veCat = new String[] {"Cars", "Buses", "Motorcycles","Others"};
String[] reCat = new String[] {"Apartment", "Plot", "Office","Paying Guest","Others"};
String[] hCat = new String[] {"Books", "Furniture", "Musical Instrument","Watches","Others"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sell);
spinner1 = (Spinner) findViewById(R.id.categorySellSpinner);
spinner2 = (Spinner) findViewById(R.id.subCategorySpinner);
selectedOption=String.valueOf(spinner1.getSelectedItem());
System.out.println(selectedOption);
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
if(selectedOption.equals("Electronics"))
{
Collections.addAll(addItemList, elCat);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(SellActivity.this,android.R.layout.simple_spinner_item, addItemList);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dataAdapter.notifyDataSetChanged();
spinner2.setAdapter(dataAdapter);
}
else if(selectedOption.equals("Home - Lifestyle"))
{
Collections.addAll(addItemList, hCat);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(SellActivity.this,android.R.layout.simple_spinner_item, addItemList);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dataAdapter.notifyDataSetChanged();
spinner2.setAdapter(dataAdapter);
}
else if(selectedOption.equals("Vehicles"))
{
Collections.addAll(addItemList, veCat);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(SellActivity.this,android.R.layout.simple_spinner_item, addItemList);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dataAdapter.notifyDataSetChanged();
spinner2.setAdapter(dataAdapter);
}
else if(selectedOption.equals("Real Estate"))
{
Collections.addAll(addItemList, reCat);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(SellActivity.this,android.R.layout.simple_spinner_item, addItemList);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dataAdapter.notifyDataSetChanged();
spinner2.setAdapter(dataAdapter);
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
}
Here is the whole code.
Data is not changing....plus old data adds onto it
Just do like this in every if condition :-
Collections.addAll(addItemList, elCat);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String(this,android.R.layout.simple_spinner_item, addItemList);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dataAdapter.notifyDataSetChanged();
spinner2.setAdapter(dataAdapter);
Old data is getting added because you are not clearing the collection you are passing into the adapter just clear the contents of the collection before adding new data into it.
Try this :-
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
addItemList.clear();
spinner2.setAdapter(null);
if(selectedOption.equals("Electronics"))
{
Collections.addAll(addItemList, elCat);
Your code has many problems:
-- Data for spinner1 is missing. From your code, it should be: {"Electronics", "Home - Lifestyle", "Vehicles","Real Estate"}
-- spinner1 does not have an adapter set on it
-- creation and usage of list addItemList is not required
-- usage of selectedOption for checking against the selected item is not required. onItemClick() gives you the selected item in int arg2
-- calling notifyDataSetChanged() to an adapter not set to any View does nothing.
-- arrays can be passed to ArrayAdapters directly, without the need for dumping them into an ArrayList
Try re-initializing the addItemList after coming inside onItemSelected before your if statement..
