情景重新

我再編寫一個RecyclerView的頁面時，數據加載完成之后，點擊進入Activity時，很卡并且無法上下滑動，查看日志發現如上信息，根據日志 HardwareRenderer….大致可以猜測出是硬件加速造成的，我使用的是模擬器，可能是對硬件加速的支持不好..

解決方法

在清單文件中對應的發生崩潰的Activity中加入
android:hardwareAccelerated=”false”
如下所示

<activity android:name=".recyclerView.RecyclerViewAct" android:hardwareAccelerated="false" />

重新運行，問題解決。
