Question

I have to add Roboto bold font style to my textview. How to implement that in android studio.

whether I have to add font family from externally or is there an option to add that internally?

I don't know what to do? Can you help me to solve this?

Answer 1

对于任何字体系列，我们必须下载该文件（.ttf 格式）并将该文件添加到我们的项目目录中。这也是在字体目录下。添加这些文件后，我们可以使用android:fontFamily属性在我们的文本视图中使用它。

Answer 2

Right from the Android Docs

To set a font for the TextView, In the layout XML file, set the fontFamily attribute to the font file you want to access.

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fontFamily="@font/roboto"/>
