How can I pick only once a value from spinner in android

I have a spinner with ten numbers 0-10 and I if someone picks a number I want him not to be able to pick the same value again. So inside ItemSelected I do the following with no result
#Override
public void onItemSelected(AdapterView<?> adapter, View v, int position, long id) {
// On selecting a spinner item
if (position > 0 && position!=tempPosition)
{
TeamSpinnerNumber = adapter.getItemAtPosition(position).toString();
tempPosition = position
}
}

Check this i worked out for you may it help you.
public class MainActivity extends AppCompatActivity {
ArrayList<String> mStrings;
ArrayAdapter<String> mStringArrayAdapter;
Spinner mSpinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSpinner = (Spinner) findViewById(R.id.spinner);
mStrings = new ArrayList<String>() {{
add("None");
add("one");
add("two");
add("three");
}};
mStringArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mStrings);
mSpinner.setAdapter(mStringArrayAdapter);
mSpinner.setSelection(0);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String string = parent.getItemAtPosition(position).toString();
if (!string.equals("None"))
removeThisFromSpinner(string);
mSpinner.setSelection(0);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
private void removeThisFromSpinner(String s) {
mStrings.remove(s);
mStringArrayAdapter.notifyDataSetChanged();
}
}

try this, hope it helps :
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.i(TAG, "onItemSelected: "+position);
//checking the position of the selected spinner item, if the previous position is not the same then do something here
if(position>0 && position!=myPosition){
}
myPosition = position;
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
and don't forget to add global variable to the class :
int myPosition = 999; // the non existed position make it global variable

Item Selected Listener
sp1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

}
public void onNothingSelected(AdapterView<?> parent) {
}
});
Toast.makeText(context, "value"+strspin, Toast.LENGTH_LONG).show();
I am working on it past two day
Please Help Me how i can fix this problem

Use the Toast inside the onITemSelected method as below.
sp1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
strspin = parent.getItemAtPosition(pos).toString();
Toast.makeText(context, "value"+strspin, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});

Unable to get Spinner value when click item

I am here trying display seleted value from dropdown spinner, but mysetOnItemSelectedListener is not working
My code is as follows:-
ArrayAdapter<String> adapter =new ArrayAdapter<String>(this, R.array.location,list);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
Toast.makeText(
parent.getContext(),
"The color is "
+ parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});

ArrayAdapter<CharSequence> adapter=ArrayAdapter.createFromResource(this,R.array.location,android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
Toast.makeText(
parent.getContext(),
"The color is "
+ spinner.getSelectedItem().toString(),
Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
Make necessary changes and try the above code.If it not works then change Charsequence to String.

try this code
spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Employee employee = employees.get(position);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Create Spinner Programmatically

I have to create a Spinner which is not in my Layout.
so I want to create it Programmatic I write the following code in My Activity class
Spinner spinner = new Spinner(this);
String option[]={"By Date","By Transaction ID","By Customer Phone"};
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,option);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item );
spinner.setAdapter(spinnerArrayAdapter);
spinner.performClick();
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentview, View v,int position, long id)
{
Log.d("in select","yes");
}
#Override
public void onNothingSelected(AdapterView<?> arg0)
{
Toast.makeText(MainMenu.this,"no",Toast.LENGTH_LONG).show();
Log.d("In No select","No");
}
});
so My question is how I can access the spinner selected item in the activity

Your only way to access it outside your listener is making a variable that will hold the position, so you would use it later.
Something like this:
public class YourActivity extends Activity {
private int curPos;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Spinner spinner = new Spinner(this);
String option[]={"By Date","By Transaction ID","By Customer Phone"};
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,option);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item );
spinner.setAdapter(spinnerArrayAdapter);
spinner.performClick();
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentview, View v,int position, long id)
{
curPos = position;
Log.d("in select","yes");
}
#Override
public void onNothingSelected(AdapterView<?> arg0)
{
Toast.makeText(MainMenu.this,"no",Toast.LENGTH_LONG).show();
Log.d("In No select","No");
}
});
}

In your onItemSelected:
#Override
public void onItemSelected(AdapterView<?> parentview, View v,int position, long id)
{
Log.d("in select","yes");
}
The position helps you to retrieve your selected item. Which, in your case, it should be:
option[position]
