how to access a spinner from another activity in android
First save the position of selected data from spinner in a String variable,
int positionOfSelectedDataFromSpinner;
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
positionOfSelectedDataFromSpinner= position;
}
Then on button click send intent to Another activity with putExtra
Intent i = new Intent (this, activity2.class);
i.putExtra("position", positionOfSelectedDataFromSpinner);
startActivity(i);
get int from getIntent in another activity
Intent intent = getIntent();
int positionToShowToSpinner = intent.getStringExtra("position");
then set the position to spinner
spinner.setSelection(positionToShowToSpinner);
I think this my solve your problem.
