How can I get Resources by name (string) and not by integer

for 开发者_如何学Goexample:

public final class R {

    public static final class raw {
        public static final int yuri=0x7f040000;
    }
}

How can I get the resource by its name? Without using R.raw.yuri = (int)

getResources().getIdentifier( "yuri" , "raw" , getPackageName() );

I found this to be extremely slow. I stripped it out of my whole project after doing some profiling and used int[] instead.
