I have 1-50 records in the database. I am fetching those data using cursor and set those values to Spinner using Simple Cursor Adapter. Now what i need is i want to set one value say 39th value as default. But not by its position i want to set by its value.
I know how to set the spinner default by its position
spinner.setSelection(39)
will set the spinner to that value.
But i didn't have any idea about setting the spinner default by its value(text) in the database. I know the values in the database. For eg "books" is one of the value in the spinner. I need to set the spinner default as books.
Is there any possible way to do this?

this is how i did it:
String[] listAges = getResources().getStringArray(R.array.ages);
// Creating adapter for spinner
ArrayAdapter<String> dataAdapter =
new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, listAges);
// Drop down layout style - list view with radio button
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
spinner_age.getBackground().setColorFilter(ContextCompat.getColor(this, R.color.spinner_icon), PorterDuff.Mode.SRC_ATOP);
spinner_age.setAdapter(dataAdapter);
spinner_age.setSelection(0);
spinner_age.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String item = parent.getItemAtPosition(position).toString();
if(position > 0){
// get spinner value
Toast.makeText(parent.getContext(), "Age..." + item, Toast.LENGTH_SHORT).show();
}else{
// show toast select gender
Toast.makeText(parent.getContext(), "none" + item, Toast.LENGTH_SHORT).show();
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Compare string with value from index
private void selectSpinnerValue(Spinner spinner, String myString)
{
int index = 0;
for(int i = 0; i < spinner.getCount(); i++){
if(spinner.getItemAtPosition(i).toString().equals(myString)){
spinner.setSelection(i);
break;
}
}
}
If you are setting the spinner values by arraylist
or array
you can set the spinner's selection by using the index of the value.
String myString = "some value"; //the value you want the position for
ArrayAdapter myAdap = (ArrayAdapter) mySpinner.getAdapter(); //cast to an ArrayAdapter
int spinnerPosition = myAdap.getPosition(myString);
//set the default according to value
spinner.setSelection(spinnerPosition);
see the link How to set selected item of Spinner by value, not by position?
If the list you use for the spinner is an object then you can find its position like this
private int selectSpinnerValue( List<Object> ListSpinner,String myString)
{
int index = 0;
for(int i = 0; i < ListSpinner.size(); i++){
if(ListSpinner.get(i).getValueEquals().equals(myString)){
index=i;
break;
}
}
return index;
}
using:
int index=selectSpinnerValue(ListOfSpinner,StringEquals);
spinner.setSelection(index,true);
You can do it easily like this.
String cls=student.getStudentClass();
class_spinner.setSelection(classArray.indexOf(cls),true);
