How can I pass this list from one activity to other ?

Then Make this list Static just like this:

public static List< Double> list_r = new ArrayList<Double>();

And Access this list in other activity like this:

private List<Double> list_my = ClassName.list_r;

Where ClassName is your Activity which consists (List< Double> list_r).

But make sure I am just showing a way of passing list. But by making List static It will consume memory even after you have finish the use of that arrayList.

You could use a double[] together with putExtra(String, double[]) and getDoubleArrayExtra(String).

Or you can use an ArrayList<Double> together with putExtra(String, Serializable) and getSerializableExtra(String) (the ArrayList part is important as it is Serializable, but the List interface is not).

use intent.putExtra();

intent.putExtra("array_list", list_r );

You may use of bundle how to use: creating bundle and sending over to new activity or save arrayList in shared preferences: http://www.vogella.com/tutorials/AndroidFileBasedPersistence/article.html

getIntent().getParcelableArrayListExtra("list");

Convert double to string, and put it in ArrayList.
In the Activity providing the data, use Intent#putExtra():

double double1 = 0.05;
double double2 = 0.02;
ArrayList <String []> list = new ArrayList <String[]>();
list.add (new String [] {String.valueOf(double_1),String.valueOf(double_2)});
Intent i = new Intent (this,YourTargetActivity.class);
i.putExtra("list", list);
startActivity(i);

Then to retrieve, use Intent#getSerializableExtra() and cast to ArrayList :

ArrayList <String[]> list = (ArrayList<String[]>) getIntent().getSerializableExtra("list");
double double1 = Double.parseDouble(list.get(0)[0]) ;
double double1 = Double.parseDouble(list.get(0)[1]) ;

vow, i think this is the hardest way that can do. above answer much easier than this. — Shayan Pourvatan, Feb 10 '14 at 08:35
