Question

How to insert the values of spinner to SQL lite database in android?

for instance my code has

ArrayList<String> yr = new ArrayList<String>();
    for (int i = 2015; i <= 2030; i++) {
        yr.add(Integer.toString(i));
    }
    ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, yr);
    adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
     year.setAdapter(adapter1);

and i want to save the year selected by the user on the database

Answer 1

May be this will work

public void insertValuesInDb(ArrayAdapter adapter) { 
  for(int i = 0; i < adapter.size(); i++) { 
        item = adapter.getItem(i)
        //insert item in database
  } 
}

Answer 2

Implement OnItemSelectedListener for your class then call setOnItemSelectedListener for the spinner.

   spinner.setOnItemSelectedListener(this);

Then add the following which gets invoked after year is selected in the dropdown:

@Override
   public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
      String item = parent.getItemAtPosition(position).toString();
      //insert item to db
   }
