我有同樣的問題，因爲我的應用程序同時適用於英語和希伯來語。以下是我所做的：
在選項卡中設置活動android:layoutDirection="ltr"。
在選項卡中，如果語言是希伯來語，則java - 在onCreate中將移動到最後一頁。
PlaceholderFragment類都在onCreateView和getPageTitl e檢查語言是否爲希伯來語，如果是，則返回視圖和標題以相反順序。
我知道這個問題是關於在普通rtl並不僅僅是希伯來文，但這種變化可通過改變條件可以輕鬆實現。

謝謝。太糟糕了，沒有更好的方法來做到這一點。 – amitairos
@amitairos我有一些東西給你。將android：layoutDirection =「ltr」添加到您的TabLayout，並在您的onCreate方法中將ViewPager更改爲viewPager.setCurrentItem（lastnumber）; –
謝謝！我做了最後一部分。 – amitairos
