Send List Objects using Intent from one Activity to another using Parcelable | Android

Question

I have Arraylist private ArrayList<Movies> mMovies; of type Movies which is implemented as Parcelable defined in MainActivity.

mMovies contains list of movies around 20.

within MainActivity inside onCreateView() method I tried to pass the parcelable objects to another Activity called DetailActivity

Intent intent = new Intent(getActivity(), DetailActivity.class);
 intent.putExtra("MOVIES", movieList);
 startActivity(intent);

Using debugger i can see the movieList contains 20 rows.

This is how i tried to read parcelable objects which was passed through intents from MainActivity.

@Override
 public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 Bundle bundle = getActivity().getIntent().getExtras();
 mMovies = getActivity().getIntent().getParcelableExtra("MOVIES");
 }

While i try to see the mMovies value using debugger it shows null

• mittmemo: Are you sure your Parcelable implementation is correct?
• Ganesh Pandey: I think its correct. You can see it here: gist.github.com/GPandey515/708ccd75327e6131ddc0

Answer 1

Use putParcelable("MOVIES",mMovies); and getParcelableArrayListExtra("MOVIES") instead. How can I make my custom objects Parcelable? may provide some more insight.

Answer 2

First, you put to extras list, but trying to get a Movie onject, use getParcelableArrayList()

Second, check out Parcelable implementation (and make sure you call right consctructor in CREATOR)

Answer 3

My suggestion is exporting the Movies class to Json String as in: Android- create JSON Array and JSON Object Then, passing it as String from one Intent to the second

• mittmemo: How do you suggest OP serializes the Movies class to JSON?
