Intent.putExtra List [duplicate]

Assuming that your List is a list of strings make data an ArrayList<String> and use intent.putStringArrayListExtra("data", data)

Here is a skeleton of the code you need:

1. Declare List

    private List<String> test;
   

2. Init List at appropriate place

    test = new ArrayList<String>();
   

   and add data as appropriate to test.

3. Pass to intent as follows:

    Intent intent = getIntent();  
    intent.putStringArrayListExtra("test", (ArrayList<String>) test);
   

4. Retrieve data as follows:

    ArrayList<String> test = getIntent().getStringArrayListExtra("test");
