kotlin中的wallpapermanager中的问题

Question

我使用一个id为home_screen的按钮在framelayout fl_iv中设置一个图像作为主屏幕墙纸。但当我点击它时，它会将图像设置为主屏幕墙纸和锁屏墙纸。怎样才能让它换掉家里的墙纸呢？代码是这样的：

home_screen.setOnClickListener {
            Toast.makeText(this@SetWallpaperActivity, "Please Wait. Setting Up", Toast.LENGTH_SHORT).show()

                val result: Bitmap = fl_iv.drawToBitmap()

                val wallpaperManager = WallpaperManager.getInstance(this)

                try {
                    wallpaperManager.setBitmap(result)

                } catch (ex: IOException) {
                    ex.printStackTrace()
                }
                Toast.makeText(this@SetWallpaperActivity, "All Done :)", Toast.LENGTH_SHORT).show()


        }

尝试在您的墙纸管理器中指定FLAG_SYSTEM

wallpaperManager.setBitmap(result, null, true, WallpaperManager.FLAG_SYSTEM)
