How do I set the font size after upgrading to 0.8.1 in Android Studio?

After upgrading to 0.8.1, open the Set Font size page, you will find whether the default or Darcula, do not allow you to change the size of the font, in fact, this is because these two modes are Android Studio self-mode, so do not allow you to change, If you want to change, you need to customize your own pattern. Such as:

Select the style you want, then click Save As and enter the name of your own defined style in the pop-up dialog box.

Then choose the scheme name as your custom style, this time you can change it.
