我有一個slidingTabLayout，我不斷收到此RunTime異常？

我已經設置了滑動標籤佈局，並且在標籤之間切換時不斷收到此運行時異常。我不確定這到底意味着什麼，任何人都可以看到這種情況？我有一個slidingTabLayout，我不斷收到此RunTime異常？

您還需要發佈您的代碼。 – drWisdom

至於你的異常說：了java.lang.RuntimeException：[email protected]必須實現OnFragmentInteractionListener

能否請您檢查MainActivity是否正在實施OnFragmentInteractionListener類？

我更新了問題 – Eli

另外問題是，當我點擊myRecent時，它將我帶到標籤頁面，並告訴我實現我的聽衆 – Eli

爲什麼我的標籤活動會影響myRecent活動？ – Eli

我有一個slidingTabLayout，我不斷收到此RunTime異常？
