Issue with fragment and view other than textview

[ankush19902]

I am using the library in one of my project. For complete activity is works fine, but if the activity has an fragment it doesn't work then. Moreover inside the fragment it doens't work using one of the exposed methods.
Also if i apply it to button or any view other then textview then also it doesn't work. Is it meant to work on these or just the acitivities.
For a button , i use TypefaceHelper.getInstance().setTypeface(addPhotoBtn, "JosefinSans-Regular.ttf");
