How to use tools:context to associtate Fragment files?

Question

Recently I came across the use-case of using tools:context in my layout files for activities. I learned that I can use it to associate an Activity class file to my layout file.

But how can I use it to associate a Fragment class file to any layout?

Bacuase as I have tried, it is only showing Activity list in autocomplete suggestion.

Answer 1

There is a bug in Android Studio, you have to write it manually, it will appear red(indicating it's unresolved) until you finish typing, then it will appear in green

Answer 2

Have you tried it doing like this:

Let's say Relative layout is your parent layout in your fragment's layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:context=".Folder.Fragment"  >

Now this .xml file will be associated with your .Fragment class which is a fragment.
