int res = getResources().getIdentifier("< packageName:drawable/imageName >'", null, null); Use this res in your iV3.

public static int getIdentifier(Context context, String name)
{
    return context.getResources().getIdentifier(name.substring(0, name.lastIndexOf(".")), "drawable", context.getPackageName());
}

Above code will return the resource id from name String.
