在寫APP時，想從.xml中獲取@drawable/picname
Resources res = getResources();
int[] imageId = res.getIntArray(R.array.bookImage);- 然後用Log.i監視值結果

最後,StackOverFlow 給出的答案是
TypedArray ar = context.getResources().obtainTypedArray(R.array.actions_images);
int len = ar.length();
int[] resIds = new int[len];
for (int i = 0; i < len; i++)
resIds[i] = ar.getResourceId(i, 0);
ar.recycle();
