A basic sample which shows how to transfer object of model between fragments simply without Pacelable and Serializable.
You can copy only KimchiDataCache file to your util folder.
1. Transfer Object(Model) Synchronously between activities and fragments
First push your data object to KimchiDataCache instance in your Activity or Fragment.
KoreanFood foodItem = new KoreanFood(1, "Kimchi", "Traditional fermented Korean side dish made of vegetables") // Sample Model
KimchiDataCache.getInstance().push(foodItem);
// add your activity or fragmentGet your data object in your Activity of Fragment that you added.
public class MainFragment extends Fragment{
private KoreanFood foodItem;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
foodItem = KimchiDataCache.getInstance().pop(KoreanFood.class);
}2. Transfer Object(Model) Asynchronously when using ViewPager
First push your data object with position to KimchiDataCache instance in FragmentStatePagerAdapter(or FragmentPagerAdapter)
private class PagerAdapter extends FragmentStatePagerAdapter {
...
public Fragment getItem(int position) {
KimchiDataCache.getInstance().push(position, foodItems.get(position));
return FoodFragment.newInstance(position);
}
}Get your data object in your Fragment of ViewPager
public static FoodFragment newInstance(int position) {
FoodFragment fragment = new FoodFragment();
Bundle args = new Bundle();
args.putInt(ARG_POSITION, position);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
final int position = getArguments().getInt(ARG_POSITION);
koreanFoodItem = KimchiDataCache.getInstance().pop(position);
}
