I have a update view, where I need to pre-select the value stored in database for a Spinner.
I was having in mind something like this, but the Adapter has no indexOf method, so I am stuck.
void setSpinner(String value)
{
int pos = getSpinnerField().getAdapter().indexOf(value);
getSpinnerField().setSelection(pos);
}

To solve the android spinner set selected, assume your Spinner is named mSpinner, and it includes as one of its options: "any value".
To find and compare the position of "some value" in the Spinner use this:
String compareValue = "some value";
ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.select_state, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(adapter);
if (compareValue != null) {
int spinnerPosition = adapter.getPosition(compareValue);
mSpinner.setSelection(spinnerPosition);
}
