How to set Spinner Default by its Value instead of Position?

Question

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?

It seems as if all you need is to fetch a value from the db. Or am I misunderstanding something? – Va

@Va No.. I fetched value from the database and set it to spinner using simple cursor adapter.. Now the thing is i need to set one value of the spinner as default by its value not by its position.. have i explained clearly – Mulderig

No, it still seems that you just have to get the value from db itself and set it with pinner.setSelection(somepositionvalue). – Trenttrento

Answer 1

Finally, i solved the problem by using following way, in which the position of the spinner can be get by its string

private int getPostiton(String locationid,Cursor cursor)
{
    int i;
    cursor.moveToFirst(); 
    for(i=0;i< cursor.getCount()-1;i++)
    {  

        String locationVal = cursor.getString(cursor.getColumnIndex(RoadMoveDataBase.LT_LOCATION));  
        if(locationVal.equals(locationid))
        { 
            position = i+1;  
            break;
        }
        else
        {
            position = 0;
        }
        cursor.moveToNext();  
    } 

Calling the method

    Spinner location2 = (Spinner)findViewById(R.id.spinner1);
    int location2id = getPostiton(cursor.getString(3),cursor);
    location2.setSelection(location2id);

I hope it will help for some one..

Perhaps a bit leaner and more elegant version might look like this: public class SpinnerHelper { public static int getPosition(String displayText, String fieldName, Cursor cursor) { int position = -1; cursor.moveToFirst(); while(cursor.moveToNext()) { String text = cursor.getString(cursor.getColumnIndex(fieldName)); if (text.equals(displayText)) { position = cursor.getPosition(); break; } } return position; } } – Cutlor

Answer 2

If you are setting the spinner values by ArrayList or Array you can assign the spinner's selection by using the value's index.

String myString = "some value"; //the value you want the position for

ArrayAdapter myAdapter = (ArrayAdapter) mySpinner.getAdapter(); //cast to an ArrayAdapter

int spinnerPosition = myAdapter.getPosition(myString);

//set the default according to the value
spinner.setSelection(spinnerPosition);

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

Also, you can avoid the temporary integer variable "spinnerPosition " by directly using the method:

getPosition(String item)

Then the assigning code will be:

//set the default according to the value
spinner.setSelection(myAdapter.getPosition(myString));

Thanks for you answer.. I know its possible using ArrayAdapter.. Is the same possible by Simple Cursor Adapter?? – Mulderig

Answer 3

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;
             }
         }
     }

Answer 4

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) {
            }
        });

Answer 5

You can do it easily like this.

String cls=student.getStudentClass();
class_spinner.setSelection(classArray.indexOf(cls),true);

Answer 6

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);
