Getting ArrayList<String> from arrays.xml file cast issue

Question

I have to get an array stored in arrays.xml as ArrayList

String arrayNames[]=MyActivity.this.getResources().getStringArray(R.array.names;
ArrayList<String> namesList=(ArrayList<String>) Arrays.asList(arrayNames));

this cause

java.lang.ClassCastException: java.util.Arrays$ArrayList cannot be cast to java.util.ArrayList

because cast from List to ArrayList seems deniend due to different implementations of List.

I need to pass ArrayList<String> so I cannot change ArrayList<String> namesList in List<String> namesList.

wondering if is there a better way to convert String in ArrayList<String> without write manually a method that iterates all array Entries and put all them in an ArrayList<String>

You cannot cast it this way, declare a new ArrayList:

ArrayList<String> namesList= new ArrayList<String>(Arrays.asList(arrayNames)));

You could write it like this:

ArrayList<String> namesList=new ArrayList<String>(Arrays.asList(arrayNames));

We were typing at the same time. I didn't see your answer.

You can try using the TypedArray

Resources resources = mContext.getResources();
TypedArray namesList = resources.obtainTypedArray(R.array.names);
