Android에서 클래스 android.support.design.widget.FloatingActionButton을 inflating하는 중 오류가 발생했습니다.

Question

응용 프로그램을 빌드 할 때 FloatingActionButton에 android.view.InflateException이 표시됩니까? 정말 오류의 원인을 모르겠습니다.

Answer 1

이 문제가 styles.xml에, 당신의 기본 테마 이름은 AppBaseTheme입니다. Mainfest 파일에서 AppTheme을 사용했음을 알 수 있듯이이를 AppTheme로 변경하십시오.

클래스 android.support.design.widget.FloatingActionButton을 유발할 수있는 모든 이유를 나열했습니다. 요령을주의 깊게 읽으십시오.

1. FAB 버튼은 디자인 라이브러리 Cpmponent입니다. 귀하의 활동은 대신 AppCompatActivity으로 연장되어야합니다.

2. 귀하의 활동 테마도 적절해야합니다 테마 .AppCompat 테마. 또한 FAB에는 colorAccent가 필요합니다. styles.xml 파일 안에 있는지 확인하십시오.

   <!-- Base application theme. --> 
   <style name="AppTheme" parent="Base.AppTheme"> 
   <!-- Customize your theme here. --> 
   </style> 
   
   <style name="Base.AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
   <item name="android:colorPrimary">@color/primary</item> 
   <item name="android:colorPrimaryDark">@color/primary_dark</item> 
   <item name="android:colorAccent">@color/accent</item> 
   </style>

   compile 'com.android.support:design:23.1.1' 
   ... 
   } 
   

5. 엑스트라의 SDK 관리자에 대한 업데이트 지원 라이브러리> 안드로이드 지원 저장소와 안드로이드 지원 라이브러리

프로젝트 build.gradle 파일 내부 설계 라이브러리를 추가하는 방법에 대한 놓치지 마세요

희망에 따라 오류가 해결되기를 바랍니다.
