（Android日常）从.xml中获取数组中的@drawable

在写APP时，想从.xml中获取@drawable/picname

Resources res = getResources();int[] imageId = res.getIntArray(R.array.bookImage);

• 然后用Log.i监视值结果
  07-09 21:34:34.809 11010-11010/com.three.learning I/image: 0
  07-09 21:34:34.809 11010-11010/com.three.learning I/image: 0
  07-09 21:34:34.809 11010-11010/com.three.learning I/image: 0
  07-09 21:34:34.809 11010-11010/com.three.learning I/image: 0
  07-09 21:34:34.809 11010-11010/com.three.learning I/image: 0
  07-09 21:34:34.809 11010-11010/com.three.learning I/image: 0

最后,StackOverFlow 给出的答案是

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();
