How to set the selected item of Spinner by value, not by position?

485 Asked by Amitjaisawal in QA Testing , Asked on Jul 2, 2021

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);

}
