Setting id of View using String Android SDK

Question

I know you can set the int id of a View using the following:

 View.setId(int id);

But is there a way to use a string instead? I know what I could do is declare an array of arrays and each array contains a string and an int associated with that string and if the string is called then it gets the int associated with that string, but is there a simpler way to do it to set the id a as a string?

Also, when a View is created during runtime on the app, does it automatically generate a unique int id for it? Thanks for the help.

Because I am making an app that requires the use of a string id for users so they don't have to deal with integers that might get confusing. — user3864563

No, there is no. View has just the setId(int) method. If your string is a number, you can convert this to int and use as id for your view.

no you have to take care of it.

So, if that's the case, could I implement it in such a way where in a loop it detects if an int id exists already? Using the getId method?

@user3864563 that's what will be returned if there's no ID associated with this View developer.android.com/reference/android/view/View.html#NO_ID

since api level 17 android introduced the method generateViewId. You can take a look to ist implmentation here: grepcode.com/file/repository.grepcode.com/java/ext/…
