Android: setSelection having no effect on Spinner

Question

I\'m having some problem with setSelection on a Spinner. I set the value to be pre-selected when the spinner is shown in code, but it has no effect and the first alternative

Answer 1

Sometimes, we may not set listeners because the spinner may be set to a certain value, and disabled as per requirement.

This can lead to setSelection() not selecting a value, since it needs a listener.

Make sure that the Spinner's setOnItemSelectedListener() is set to a custom listener like below.

Even if spinner is disabled, we must set a listener like below, so that setSelection() method works.

spinnerListener.setOnItemSelectedListener(spinnerListener);
AdapterView.OnItemSelectedListener spinnerListener = new 
AdapterView.OnItemSelectedListener() 
{
    @Override
    public void onItemSelected(AdapterView adapterView, View view, int position, long l) {
      //Your code
    }
}
spinnerListener.setSelection(0);
