Question

There is problem of class casting. Please tell me how to cast this. I want to this ArrayList<CharSequence> in my CharSequence[] named Contacts.

java.lang.ClassCastException (in Android):

CharSequence[] Contacts;
List<CharSequence> contacts = new ArrayList<CharSequence>();


Contacts = (CharSequence[]) contacts.toArray();

for(CharSequence p : contacts) {
    Log.i("log_tag", "AAAAAAAAAAAAAAAAAAA" + p);
}

Answer 1

Try this:

Contacts = contacts.toArray(new CharSequence[contacts.size()]);

Although, I would advise you to rename Contacts to something else, perhaps contactsArray. Two reasons for this: 1) Java variable names generally start with a lower-case letter. 2) You have another variable named contacts, defining a second to be Contacts will make the code much harder to read and understand since the two names differ only by the case of the first letter.
