In your Activities onCreate() method do the following.
1. Get the spinner object
Ex:
Spinner obj = findViewById(R.id.spinner);
2. Add listener to it
obj.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
//TODO
}
});
3. obj.setSelection(yourInitialPosition,false);
NOTE1: By calling this above method, Android make sure that the onItemSelected is not called 2 times. It will be called only once after the activity launches first time.
NOTE2: If we don't call the setSelection(int,boolean); at all then by default android calls onItemSelected with default position as 0.
NOTE3: if we call set setSelection(int) instead, then onItemSelected will be getting called twice.
public void setSelection (int position, boolean animate)
Jump directly to a specific item in the adapter data.
