You can instantiate an ArrayAdapter typed with you data object type. The Spinner will then hold your complete data object instead of a String. Values displayed will be determined by the toString() method of your data objects.

Example:

List allProjects = ...;

    ArrayAdapter spinnerAdapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item,allProjects.toArray(new Project[allProjects.size()]));
    spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(spinnerAdapter);
    spinner.setOnItemSelectedListener(this);

...

@Override
public void onItemSelected(AdapterView parent, View view, int position, long id) {
    Log.i(AppConst.TAG, "ItemSelected:" + position + " id: " + id);
    Project selectedProject = (Project)getSpinner().getSelectedItem();
    currentTask = selectedProject.toString();
    Log.i(AppConst.TAG, "Selected Project:" + selectedProject.getId());
    ...
}
