如果我得到的图像的名字像下面的变量：

  VAR imageName = SERVICE.getImg（）;
 

然后，我怎么能得到与 R.drawable资源。???? ，我试过 R.drawable [imageName] ，但是失败了。有什么建议？

 内部ID = getResources（）则getIdentifier（imageName，类型，封装）。
 

This将让你你正在寻找的资源的ID 。有了它，你就可以从R类访问的资源。

If I get the image name as a variable like following:

var imageName = SERVICE.getImg();

Then, how can I get the resource with R.drawable.????, I tried R.drawable[imageName], but it failed. Any suggestions?

int id = getResources().getIdentifier(imageName, type, package);

This will get you the ID of the resource you are looking for. With it, you can then access the resource from the R class.
