Android, how to populate a CharSequence array dynamically (not initializing?)
You are almost there. You need to allocate space for the entries, which is automatically done for you in the initializing case above.
CharSequence cs[];
cs = new String[2];
cs[0] = "foo";
cs[1] = "bar";
Actually CharSequence is an Interface and can thus not directly be created, but String as one of its implementations can.
Use a List object to manage items and when you have all the elements then convert to a CharSequence. Something like this:
List<String> listItems = new ArrayList<String>();
listItems.add("Item1");
listItems.add("Item2");
listItems.add("Item3");
final CharSequence[] charSequenceItems = listItems.toArray(new CharSequence[listItems.size()]);
You can also use List
, to have a dynamic number of members in the array(list :)):
List<CharSequence> cs = new ArrayList<CharSequence>();
cs.add("foo");
cs.add("bar");
If you want to use array, you can do:
CharSequence cs[];
cs = new String[2];
cs[0] = "foo";
cs[1] = "bar";
