反转此ArrayList的最简单方法是什么？
ArrayList<Integer> aList = new ArrayList<>();
//Add elements to ArrayList object
aList.add("1");
aList.add("2");
aList.add("3");
aList.add("4");
aList.add("5");
while (aList.listIterator().hasPrevious())
Log.d("reverse", "" + aList.listIterator().previous());
Collections.reverse(aList);
示例(Reference):
ArrayList aList = new ArrayList();
//Add elements to ArrayList object
aList.add("1");
aList.add("2");
aList.add("3");
aList.add("4");
aList.add("5");
Collections.reverse(aList);
System.out.println("After Reverse Order, ArrayList Contains : " + aList);
