到目前爲止，通過下面的代碼，我可以在向上滾動webview時顯示工具欄，並在web視圖向下滾動時顯示工具欄，失去了網頁視圖的滾動行爲本身隱藏工具欄時無法啓用webview的滾動行爲
這是我app_bar.xml

這是我在我的片段使用news.xml。我的問題是如果我刪除NestedScrollView我能夠滾動webview &做刷卡刷新功能，但是當我添加嵌套視圖我可以向上滾動工具欄向上&但刷新webview &的滾動屬性是失去

我跟着你的建議，但沒有任何效果可言。我的webview是WebChromeClient。我沒有設置任何關於默認滾動它的屬性。我還使用導航抽屜它是否必須做任何事情？ – choman
已更新的答案。 –
刷新刷新終於與代碼工作但是我無法滾動webview作爲佈局顯然使webview的滾動固定。我現在可以隱藏和顯示工具欄/刷新我的webview，但沒有水平滾動。如果它有幫助，我已經更新了包含webview的片段。 – choman
