如何意图ArrayList <ClassObject> 从片段到活动

Question

I want to send ArrayList contains getter setter class objects. But I'm facing an error like:

The method putParcelableArrayListExtra(String, ArrayList<? extends Parcelable>) in the type Intent is not applicable for the arguments (String, ArrayList<BloodDonor>)

// Call New Activity

ArrayList<BloodDonor> bloodDonors = filterData(selectedCountry, selectedState, selectedCity, selectedZip, selectedbloodgroup);
Intent intent = new Intent(getActivity(), DonerListActivity.class);
intent.putParcelableArrayListExtra("bloodDonorList", bloodDonors);
startActivity(intent);

// declaration of filterData() method.

private ArrayList<BloodDonor> filterData(String SelectedCountry,
        String selectedState, String selectedCity, String selectedZip,
        String bloodgroup) {

    ArrayList<BloodDonor> bloodDonor = new ArrayList<BloodDonor>();

    Log.d("DB", "values in filter" + SelectedCountry + selectedState
            + selectedCity + selectedZip);

    DatabaseHelperDao helperDao = new DatabaseHelperDao(getActivity());
    try {
        helperDao.open();
        bloodDonor = helperDao.fatchDoner(SelectedCountry,
                selectedState, selectedCity, selectedZip, bloodgroup);
    } catch (Exception e) {
        e.getStackTrace();
    } finally {
        helperDao.close();
    }
    return bloodDonor;

}

dao method fetchdonor() return donors list. Please Help me here.Thanks

Probably you missed to implements Parcelable interface in your BloodDonor object.
