What is the difference between fontFamily and typeFace in android?

Question

What is the difference between fontFamily and typeFace in android ? Of course, I read all the description in android developer site, but I\'m not clear yet.

According to

Answer 1

To find the answer of your question you have to look into the source code of TextView, you will find its implementation here

https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/java/android/widget/TextView.java

Now from the implementation of method setTypefaceFromAttrs() it seems like, If you have set fontFamily attribute then typeface attribute will be ignored.

Also android:typeface attribute is added in api level 1 and using this you can set following fonts

- normal
- serif
- sans
- monospace

Whereas android:fontFamily attribute is added in api level 16 and this supports more fonts from roboto font family like -

- serif
- monospace
- sans-serif
- sans-serif-condensed
- serif-monospace
- sans-serif-smallcaps
