1- Open a new project inAndroid Studioand select the desired name for it. The custom name selected in this tutorial is CustomFont. (change font in android studio)2- The type of activity that we must choose in this part of the training for this project is Empty Activity.3- It should be noted that font change settings can be applied without using Java language and methods, which is why there is no emphasis on choosing Java language in this part of training and project creation.4- With the introduction of API 26 in the three versions of Android, a new feature has been added that can specify different types of fonts for the widget. Specifying fonts for the widget using this method eliminates the need to use Java methods.5- In this method of specifying fonts, you can add the fontFamily property for each of the widgets and specify the fonts for them.6- To do this, we must add the appcompat-v7 library to the project. Because the appcompat-v7 library is one of the most essential to apply these settings to change the font.7- Add a directory with the desired font name to res.
Res> New> Android Resource Directory
8- Then we have to save our desired font file using .ttf or .otf extensions and add it to this directory. It is better to be careful in choosing fonts and use fonts that are slang and have a positive effect on user interface design.

Note:

It is better to use lower case letters, numbers and lines in naming and choosing names for fonts. We can choose the names we want for the fonts and we will use the names we have chosen for them in the definition in this project.
