整个activity防止录屏

在onCreate里设置布局之前加入

window.setFlags(
            WindowManager.LayoutParams.FLAG_SECURE,
            WindowManager.LayoutParams.FLAG_SECURE
        )

SurfaceView 防止录屏、截屏

主要代码：
surfaceView.setSecure(true)
试列：

val surfaceView = SurfaceView(this)
surfaceView.setSecure(true)
surfaceView.setZOrderMediaOverlay(true)
val layoutParams = FrameLayout.LayoutParams(
                        FrameLayout.LayoutParams.MATCH_PARENT,
                        FrameLayout.LayoutParams.MATCH_PARENT
                    )
surfaceView.layoutParams = layoutParams
binding.flLocal.addView(surfaceView)
