使用Singleton类初始化/访问的ArrayList

这是创建单例类的方法：

    public class YourSingleton  {        private static YourSingleton mInstance;        private ArrayList<String> list = null;        public static YourSingleton getInstance() { if(mInstance == null)     mInstance = new YourSingleton(); return mInstance;        }        private YourSingleton() {          list = new ArrayList<String>();        }        // retrieve array from anywhere        public ArrayList<String> getArray() {         return this.list;        }        //Add element to array        public void addToArray(String value) {         list.add(value);        }}

任何需要调用arrayList的地方都可以：

YourSingleton.getInstance().getArray();

要将元素添加到数组，请使用：

 YourSingleton.getInstance().addToArray("first value");

要么

YourSingleton.getInstance().getArray().add("any value");
