问androidStudio使用播放器报错？

使用androidStudio开发，引用playersdk.aar包。在XML中添加下面的代码，并在activity的oncreate方法中setContentView时就会报错。<com.tencent.qcload.playersdk.ui.VideoRootFrame** **android**:id=**"@+id/player"** **android** ayout_width=**"match_parent"** **android** ayout_height=**"**match_parent**"></com.tencent.qcload.playersdk.ui.VideoRootFrame>重要报错内容如下： Caused by: java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.RelativeLayout at com.tencent.qcload.playersdk.ui.VideoRootFrame.init(VideoRootFrame.java:125) at com.tencent.qcload.playersdk.ui.VideoRootFrame.<init>(VideoRootFrame.java:107) at java.lang.reflect.Constructor.constructNative(Native Method) at java.lang.reflect.Constructor.newInstance(Constructor.java:417) at android.view.LayoutInflater.createView(LayoutInflater.java:594) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:696) at android.view.LayoutInflater.rInflate(LayoutInflater.java:755) at android.view.LayoutInflater.inflate(LayoutInflater.java:492) at android.view.LayoutInflater.inflate(LayoutInflater.java:397) at android.view.LayoutInflater.inflate(LayoutInflater.java:353) at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:267) at android.app.Activity.setContentView(Activity.java:1915) at player.hx.videoplayer.VideoActivity.onCreate(VideoActivity.java:40) at android.app.Activity.performCreate(Activity.java:5234) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2302) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2388) at android.app.ActivityThread.access$900(ActivityThread.java:148) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1319) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:5457) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:525) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:806) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:622) at dalvik.system.NativeStart.main(Native Method) 就是说包里面有个地方本该是RelativeLayout的结果写成了LinearLayout而强转错误。
