The font change of Android Netease Cloud Reading was achieved through custom font. The user can change the font by setting the font in the Netease Cloud Reading. The specific steps were as follows: 1. The user finds the "font" option in the settings and chooses the desired font file. 2 Add the font file to the res folder of the Android app. 3 Add a font reference to the res/values/font file of the application so that the font can be used in the application. For example, if the user chooses a font file named "Arial", add the following code to the res/values/font file: ``` <font name=Arial style=font-family: Arial;/> ``` Arial is the name of the font file, and the style parameters specify the font style such as font size, color, and so on. For example, when you enter text in a text box, you can use the following code to call the font method: ``` fontsetTypeface(new Typeface(Arial)); ``` The "font" is the name of the custom font, and the "setType face" method is used to set the font type. Through the above steps, users can change the font in the Netease Cloud Reading and set it according to their own needs.
