[Q#7063831][A#7063917] Android, how to populate a CharSequence array dynamically (not initializing?)

How do I change something like this: to:

Answer

Use a List object to manage items and when you have all the elements then convert to a CharSequence. Something like this:

APIzation

List<String> listItems = new ArrayList<String>();

listItems.add("Item1");
listItems.add("Item2");
listItems.add("Item3");

final CharSequence[] charSequenceItems = listItems.toArray(new CharSequence[listItems.size()]);

package com.stackoverflow.api;

import java.util.ArrayList;
import java.util.List;

public class Human7063917 {

  public static CharSequence[] getCharSequence(String... items) {
    List<String> listItems = new ArrayList<>();
    for (String item : items) {
      listItems.add(item);
    }

    return listItems.toArray(new CharSequence[listItems.size()]);
  }
}

import java.util.List;
