Android Build a Weather App (2015) Concurrency and Error Handling Configuring the Alert Dialog

Posted by yuehwencheng

Does it make any difference whether to use context.GetString() or not when setting title value of AlertDialog.Builder?

When using opt-Enter to extract string resource as instructed in the video, my Android Studio didn't convert the string to context.GetString(R.string.error_title) but to simply R.string.error_title.

The code runs fine to display the error massage with AlertDialog and nothing weird showed in Log after execution.

So, does it make any difference whether to use context.GetString() or not when setting title value of AlertDialog.Builder?

Thanks!

I'm seeing the same thing. Are you using Android Studio 1.3.2?

You can check the method AlertDialog.Builder(context).setTitle() documentation here: http://developer.android.com/reference/android/app/AlertDialog.Builder.html#setTitle(java.lang.CharSequence)

Context.getString(int resId): Receives as parameter the given resource id (integer) , and R.string.error_title: Is the resource id (integer)

But the setTitle method as you can see in the documentation can receive a CharSequence or an integer (resourceId). That's why it works with context.GetString(R.string.error_title) or R.string.error_title.

I guess where I'm failing to understand why Android Studio did this in previous versions is because.... isn't the context of R (resources) already "the entire app"?

When would a situation come up where I'd want to use a Context to get a string from R that would produce different results than just accessing the property/field directly from R?
