Bundle does not fully received

I am facing a problem with sending data through the bundle.

Intent toAudio = new Intent(TourDescription.this, Audio.class);
toAudio.putParcelableArrayListExtra("poi", arraypoi);
startActivity(toAudio);

here am sending arraypoi which is an ArrayList. This ArrayList contains a set of values.

And in the receiving class, I have like this

listOfPOI = getIntent().getParcelableArrayListExtra("poi");
Collections.sort(listOfPOI);

where listOfPOI is also an array list.

The problem am facing is, I am not able to receive values for 3 particular variables in listOfPOI (coming as null), rest all values are coming proper.

While sending the bundle, I mean in arraypoi also I am able to send all the values correct开发者_C百科ly but the problem is while receiving it.

Note: My class is implemented as parcelable only.

Any answer for this?

There are two workarounds in my point of view.

First:

You need to make YourOwnArrayList as subclass of ArrayList<YourObject> and implements Parcelable. Tutorial Here

Second:

pass your Object using for() loop. like this.

Intent toAudio = new Intent(TourDescription.this, Audio.class);
toAudio.putExtra("SIZE", arraypoi.size());
for(int i=0; i<arraypoi.size(); i++)
    toAudio.putExtra("POI"+i, arraypoi.get(i));
startActivity(toAudio);

and while getting in other class

Bundle data = getIntent().getExtras();
int size=data.getInt("SIZE");
for(int i=0; i<size; i++)
    listOfPOI.add((YOUR_OBJECT) data.getParcelable("POI"+i));

YOUR_OBJECT is the class name of your Object.
