How to Pass a Double ArrayList in an Android Bundle

I need to pass a Double ArrayList between activities in an Android application using a Bundle. I noticed that there is a method bundle.putIntegerArrayList(), but I cannot find a corresponding method for Double ArrayList.

Here’s a sample code snippet that illustrates the problem:

ArrayList<Double> doubleArrayList = new ArrayList<>();
doubleArrayList.add(1.0);
doubleArrayList.add(2.0);
doubleArrayList.add(3.0);

Bundle bundle = new Bundle();
bundle.putDoubleArrayList("key", doubleArrayList); // This method doesn't exist

Problem:

The Bundle class does not have a putDoubleArrayList() method, and I am unsure how to pass a Double ArrayList using a Bundle.

Question:

How can I pass a Double ArrayList in a Bundle? What is the correct method or approach to achieve this?

What I've Tried:

Looking for Alternative Methods: I checked the documentation and found that Bundle supports putIntegerArrayList(), putStringArrayList(), but there is no putDoubleArrayList() method.

Converting to Primitive Arrays: I considered converting the Double ArrayList to a primitive double[] array before putting it in the Bundle.

Solution

  • Why you need use bundle. you can just put it in Intent directly. And because Array list implement Serializable you won't have any problems. 

    intent.putExtra("array", doubleArray);

    If you need use Bundle then 

    bundle.putSerializable("array", doubleArray);
