How to Pass ArrayList from Activity to Fragment in Android

Question

I have a MainActivity and a fragment. What I want to do is pass array list from my main activity to my fragment.

In my MainActivity my code looks like this:

private final List<RestaurantParcelableModel> restaurantList = new ArrayList<>();
...
RestaurantsFragment restaurantsFragment = new RestaurantsFragment();
        Bundle args = new Bundle();
        args.putParcelableArrayList("restaurantList", (ArrayList<? extends Parcelable>) restaurantList);
        restaurantsFragment.setArguments(args);

        FragmentManager fragmentManager = getFragmentManager();
        android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.restaurants_list, restaurantsFragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();

Right now I am getting this error in fragmentTransaction.replace(R.id.restaurants_list, restaurantsFragment); - "Wrong 2nd argument type. Found: 'com.test.restaurants.sliderfragments.RestaurantsFragment', required: 'android.app.Fragment' replace (int, android.app.Fragment) in FragmentTransaction cannot be applied to (int, com.test.restaurants.sliderfragments.RestaurantsFragment)"

Is your `RestaurantsFragment` extending `Fragment` correctly? — malmling, Sep 29 '16 at 09:36
Also be sure that `RestaurantParcelableModel` implements `Parcelable`. Because such type of casting - `(ArrayList extends Parcelable>) restaurantList ` is quiet danger. — Andrii Abramov, Sep 29 '16 at 09:38
Your fragment have to extend `android.app.Fragment` not a `android.support.v4.app.Fragment;` in this particular case — W.Kurek, Sep 29 '16 at 09:44
Then use `getSupportFragmentManager()` instead of `getFragmentManager()` — Sanoop Surendran, Sep 29 '16 at 09:46

@Kemo the same error i was facing now I used fragment support manager instead of fragment manager.Now its working fine.

        FragmentManager fragmentManager = getSupportFragmentManager();
        android.support.v4.app.FragmentTransaction fragmentTransaction = 
        fragmentManager.beginTransaction();
        BlankFragment blankFragment = new BlankFragment();
        fragmentTransaction.add(R.id.ll, blankFragment, "");
        fragmentTransaction.commit();

It's because your class RestaurantParcelableModel does not implements the Parceable class. Implement parceable class and override the required methods.

You can use Bundle to send your ArrayList:

Bundle args = new Bundle();
args.putStringArrayList("array", mArrayList);
restaurantsFragment.setArguments(args);

You have to delete line: import android.support.v4.app.Fragment; and change it for import android.app.Fragment;

Now to fix the issue you have to handle your imports.

Either use import android.app.Fragment instead of import android.support.v4.app.Fragment

Or Update the main content of your app with a support Fragment manager like this:

FragmentManager fragmentManager = getSupportFragmentManager().

But then you also have to change the type of the FragmentManager itself; import android.app.FragmentManager to import android.support.v4.app.FragmentManager;

@Kemo Hope it helped :) – Sanoop Surendran Sep 29 '16 at 09:50
It did :) thank you Sanoop. I used import android.app.Fragment instead of import android.support.v4.app.Fragment. – Banana Sep 29 '16 at 09:51
I also tried using getSupprotFragmentManager(), but I got this error: "Cannot resolve symbol FragmentTransaction" in my code: `FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.replace(R.id.restaurantss_list, restaurantsFragment); fragmentTransaction.addToBackStack(null); fragmentTransaction.commit();` – Banana Sep 29 '16 at 10:09
Change those imports also.. @Kemo For Transaction – Sanoop Surendran Sep 29 '16 at 10:18
I did, `android.support.v4.app.FragmentTransaction`, but it is showing as "unused import statement" – Banana Sep 29 '16 at 10:20
use this android.app.FragmentTransaction – Sanoop Surendran Sep 29 '16 at 10:21
`import android.app.Fragment; import android.app.FragmentManager; import android.app.FragmentTransaction;` – Sanoop Surendran Sep 29 '16 at 10:23

You can use parceable or serializabale to pass the object of arraylist or array list.You can find the example of parceable from the givenlink of github. ParceableSample.zip download the zip file

You can use the above link sample for passing the Array list or Object of array list.
