Android Studio 3.0 xml 레이아웃 프리뷰 꺠짐

이번에 업데이트 된 Android Studio 3.0 xml 레이아웃 프리뷰 에러.

관련하여 해결 방법 공유해드립니다.

안드로이드 스튜디오 2.x 에서 xml 프리뷰에서 한글이 꺠져 보이는 현상으로 폰트 xml 고치신 기억이 있으실 껍니다.

해당 스튜디오를 3.0대로 업데이트하면 프리뷰가 안나오는 현상이 나옵니다.

아래 코드를 설치 폴더 아래 위치에 있는 fonts.xml을 아래 표의 내용으로 변환하신뒤 

재실행하시면 정상적으로 표시 되는 것을 확인하실수있습니다.

<?xml version="1.0" encoding="utf-8"?> <!-- WARNING: Parsing of this file by third-party apps is not supported. The file, and the font files it refers to, will be renamed and/or moved out from their respective location in the next Android release, and/or the format or syntax of the file may change significantly. You must not parse this file for information about system fonts. Instead, you must call android.text.FontManager#getSystemFonts(). For example, it can be called as context.getSystemService(FontManager.class).getSystemFonts(). Note that the returned FontConfig includes data on all the defined font families and all the details about weight, style, etc. It also provides an open file descriptor to each font file. Note that callers of the API should ensure they close the given file descriptors once they are done using them. In this file, all fonts without names are added to the default list. Fonts are chosen based on a match: full BCP-47 language tag including script, then just language, and finally order (the first font containing the glyph). Order of appearance is also the tiebreaker for weight matching. This is the reason why the 900 weights of Roboto precede the 700 weights - we prefer the former when an 800 weight is requested. Since bold spans effectively add 300 to the weight, this ensures that 900 is the bold paired with the 500 weight, ensuring adequate contrast. --> <familyset version="22"> <!-- first font is default
