TAG
이 언급 된 경우를 제외하고 내 활동의 거의 모든 항목이 정상적으로 작동합니다. TAG
빨간 선을 얻고 'TAG' has private access in 'android.support.v4.app.FragmentActivity'
라고 말합니다. 나는 이것이 무엇을 의미하는지에 대한 단서가 없으므로 여기서 나를 도와주세요. (수입 제외)'TAG'에는 'android.support.v4.app.FragmentActivity'의 개인 액세스 권한이 있습니다.

[FragmentActivity] (https://github.com/android/platform_frameworks_support/blob/master/v4/java/android/support/v4/app/FragmentActivity.java#L82)의 소스 코드를 살펴보면 82 행의 'TAG'은 비공개입니다. –
공개해야합니까? –
잠긴 것 같습니다 –
