如何在Android中获取名称或ID图像

Question

I would like to know how I can get name image. I use setImageResource(R.drawable.id). How I can get this sentence: "R.drawable.id" in code?

Answer 1

如果您是指所指图像的名称，请使用此名称。

String resName = getResourceNameFromClassByID(R.drawable.class, R.drawable.id);

Answer 2

R refers to the R.java file under gen folder ..

every time you add a resource an id is created automatically in this file, so R should be resolved to your package name.R
