我想存储的图像标识在R.drawable的形式。*使用XML文件值的数组里面,然后检索我的活动阵列。任何想法如何实现这一目标?谢谢你。
I would like to store image Id's in the form of R.drawable.* inside an array using an XML values file, and then retrieve the array in my activity. Any ideas of how to achieve this? Thanks.
您使用在在您的资源文件夹arrays.xml文件类型数组看起来是这样的:
You use a typed array in arrays.xml file within your res folder that looks like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="random_imgs">
<item>@drawable/car_01</item>
<item>@drawable/balloon_random_02</item>
<item>@drawable/dog_03</item>
</string-array>
</resources>
然后在你的活动访问它们像这样:
Then in your activity access them like so:
TypedArray imgs = getResources().obtainTypedArray(R.array.random_imgs);
//get resourceid by index
imgs.getResourceId(i, -1)
// or set you ImageView's resource to the id
mImgView1.setImageResource(imgs.getResourceId(i, -1));

由benoffi7建议建议:
Suggested recommendation by benoffi7:
使用IMGS之后添加以下行: imgs.recycle();
After using "imgs" add the following line: imgs.recycle();
