Convert String containing an ID into an Integer-ID

Question

I have a short question:

How is it possible to convert a String, containing the Id of a Drawable, which is

String idString = \"R.drawable.bubblegum\"         


        

Answer 1

Although this question is rather old already, the thing you're missing is that "id" and "drawable" are different resource types. So instead of

getResources().getIdentifier(stringId, "id", "my.Package");

it's

getResources().getIdentifier(stringId, "drawable", "my.Package");

You can also get package name with the activity context like activityContext.getPackageName()

/**
 * Returns Identifier of String into it's ID as defined in R.java file.
 * @param pContext
 * @param pString defnied in Strings.xml resource name e.g: action_item_help
 * @return
 */
public static int getStringIdentifier(Context pContext, String pString){
    return pContext.getResources().getIdentifier(pString, "string", pContext.getPackageName());
}
