Try,

ArrayList<String> list = new ArrayList<String>() {{
    add("item1");
    add("item2");
    add("item3");
}}

OR

ArrayList<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
list.add("item3");

这里是：

List<String> sample = new ArrayList<String>(Arrays.asList("item1", "item2", "item3"));
