你有沒有試過在發佈這個問題之前在互聯網上搜索？ – Denny

android.view.InflateException: Binary XML file line #2: Error inflating class android.support.constraint.RelativeLayout

你有，你有一個名爲android.support.constraint.RelativeLayout的XML元素的佈局資源。 Android中沒有這樣的類。 RelativeLayout可以在您的佈局中簡稱爲RelativeLayout。

可以發佈哪個API來開發應用程序嗎？你有沒有做過任何更新？檢查你的SDK包，

否則

創建一個activity2.xml一個線性佈局或相對佈局，並在烏拉圭回合的setContentView拆卸舊activity1.xml申請您的活動，並運行應用程序..

試試這個
