Dynamic Resource Loading Android

Question

I\'m trying to find a way to open resources whose name is determined at runtime only.

More specifically, I want to have a XML that references a bunch of other XML fi

Answer 1

I wrote this handy little helper method to encapsulate this:

public static String getResourceString(String name, Context context) {
    int nameResourceID = context.getResources().getIdentifier(name, "string", context.getApplicationInfo().packageName);
    if (nameResourceID == 0) {
        throw new IllegalArgumentException("No resource string found with name " + name);
    } else {
        return context.getString(nameResourceID);
    }
}

Answer 2

There is another method:

int drawableId = R.drawable.class.getField("file1").getInt(null);

According to this blog it's 5x times faster than using getIdentifier.

Answer 3

I haven't used it with raw files or xml layout files, but for drawables I use this:

getResources().getIdentifier("fileX", "drawable","com.yourapppackage.www");

to get the identifier (R.id) of the resource. You would need to replace drawable with something else, maybe raw or layout (untested).
