我有一个XML文件中的一个整数数组如下：

I have an integer array in an xml file as follows

<integer-array name="myArray">
    <item>@drawable/pic1</item>
    <item>@drawable/pic2</item>
    <item>@drawable/pic3</item>
    <item>@drawable/pic4</item>
</integer-array>

在code，我试图加载这个数组

In the code, I am trying to load this array

int[] picArray = getResources().getIntArray(R.array.myArray);

预期的结果是

The expected result is

R.drawable.pic1, R.drawable.pic2,R.drawable.pic3

，而是它是未来与所有值的数组为零

but instead it is coming with an array with all values as zero

谁能告诉我什么是错？

推荐答案

您需要获得与ID的图像阵列。 也许这篇文章帮助你。这样一来，code，你可能需要：

You need to get an array with id's of your images. Probably this article helps you. And so the code you probably need:

int[] picArray = new int[4];

for (int i = 1; i <=4; i++)
{
  try 
  {
    Class res = R.drawable.class;
    Field field = res.getField("pic"+i);
    picArray[i-1] = field.getInt(null);
  }
  catch (Exception e)
  {
    Log.e("MyTag", "Failure to get drawable id.", e);
  }
}
