您必须首先检测到已开始录制

您可以通过注册显示监听器来实现这一点

 val displayManager = getSystemService(Context.DISPLAY_SERVICE) as? DisplayManager
        displayManager?.registerDisplayListener(listener, null)
       

    val listener = object : DisplayManager.DisplayListener {
        override fun onDisplayChanged(displayId: Int) {
            
        }

        override fun onDisplayAdded(displayId: Int) {
            
            // here stop video player 
        }

        override fun onDisplayRemoved(displayId: Int) {
          
        }
    }

FLAG_SECURE将使屏幕录音记录为空白屏幕
