Question

--stacktrace

我想将视图ID转换为public void buttonA1(View view) { int[] board = {R.id.A1, R.id.A2, R.id.A3, R.id.B1, R.id.B2, R.id.B3, R.id.C1, R.id.C2, R.id.C3}; int i=view.getId().intValue; //even this one didn't work }，以便我可以在数组中查找，如图所示。我怎么做？我尝试了类似int之类的东西，但它一直说数组没有int posNew = Arrays.asList(board).indexOf(view.getId())类型的对象。我甚至尝试了这个Integer，但它仍然没有用。

Answer 1

int i=view.getId();会将视图ID作为整数值返回。并使用排序逻辑来检查整数数组中id的位置。

Answer 2

我不知道你为什么要将它们添加到数组中，但这样可以正常工作

ArrayList需要对象，所以将原语int包装在Integer对象中所以

ArrayList<Integer>arrayList;
arrayList = new ArrayList<>();

arrayList.add(new Integer(R.id.button));
arrayList.add(new Integer(R.id.button1));

Answer 3

已查看了ID IS 整数。无需转换任何东西。如果您想将int转换为Integer，请：

Integer viewId = new Integer(view.getId());

可以胜任。

Answer 4

per documentation，getId()方法已返回int。不需要转换或方法
