How would you save and retrieve a spinners selection, so when you come back the same item on the spinner is selected? Maybe with shared preferences?
to Save data on the sharedPreferences
( put this code on the onItemSelected()
method and save the selected value's position of your spinner
) :
int userChoice = spinner.getSelectedItemPosition();
SharedPreferences sharedPref = getSharedPreferences("FileName",0);
SharedPreferences.Editor prefEditor = sharedPref.edit();
prefEditor.putInt("userChoiceSpinner",usersChoice);
prefEditor.commit();
To get data from sharedPreferences
:
SharedPreferences sharedPref = getSharedPreferences("FileName",MODE_PRIVATE);
int spinnerValue = sharedPref.getInt("userChoiceSpinner",-1);
if(spinnerValue != -1) {
// set the selected value of the spinner
spinner.setSelection(spinnerValue);
}
refer this : set selection in spinner and this : get the position of the selected item in a spinner
