Android: Programmatically iterate through Resource ids

Question

I want to be able to iterate through all of the fields in the generated R file.

Something like:

for(int id : R.id.getAllFields()){
//Do something wit         


        

Answer 1

I found that "Class.forName(getPackageName()+".R$string");" can give you access to the string resources and should work for id, drawable, exc as well.

I then use the class found like this:

---

import java.lang.reflect.Field;

import android.util.Log;

public class ResourceUtil {

    /**
     * Finds the resource ID for the current application's resources.
     * @param Rclass Resource class to find resource in. 
     * Example: R.string.class, R.layout.class, R.drawable.class
     * @param name Name of the resource to search for.
     * @return The id of the resource or -1 if not found.
     */
    public static int getResourceByName(Class Rclass, String name) {
        int id = -1;
        try {
            if (Rclass != null) {
                final Field field = Rclass.getField(name);
                if (field != null)
                    id = field.getInt(null);
            }
        } catch (final Exception e) {
            Log.e("GET_RESOURCE_BY_NAME: ", e.toString());
            e.printStackTrace();
        }
        return id;
    }
}
