处理视频旋转逻辑

解决自动旋转和点击按钮旋转冲突问题（点击按钮旋转回退竖屏后，不能自动旋转）

答:其实只要在点击按钮旋转回竖屏时再加一句代码就行了

( activity.requestedOrientation=ActivityInfo.SCREEN_ORIENTATION_USER)

//按钮点击事件

img_fullScreen.setOnClickListener {

        //横屏的时候

        if (resources.configuration.orientation==Configuration.ORIENTATION_LANDSCAPE){

            //变成竖屏

            activity.requestedOrientation=ActivityInfo.SCREEN_ORIENTATION_PORTRAIT

         activity.requestedOrientation=ActivityInfo.SCREEN_ORIENTATION_USER

        }else{

            activity.requestedOrientation=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE

        }

    }

}

//initWidth和initHeight是竖屏时当前布局的宽和高

override fun onConfigurationChanged(newConfig:Configuration) {

    isFullScreen = newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE

    if (!isFullScreen){

        layoutParams.width=initWidth

        layoutParams.height=initHeight

        activity.window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

    }else{

        layoutParams.width = LayoutParams.MATCH_PARENT

        layoutParams.height =LayoutParams.MATCH_PARENT

        activity.window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

}

    super.onConfigurationChanged(newConfig)

}
