WindowManager.LayoutParams 札记

WindowManager.LayoutParams wlp = new WindowManager.LayoutParams(width,
                        height, WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
                        WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
                                | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
                                | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
                                | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                        PixelFormat.TRANSLUCENT);

//TYPE_SYSTEM_ERROR +FLAG_LAYOUT_IN_SCREEN 搭配能够浮在状态栏上面 而且 可以 处理 touch 和 click 事件, TYPE_SYSTEM_OVERLAY , TYPE_SYSTEM_ALERT不可以touch 和 click

WindowManager.LayoutParams wlp = new WindowManager.LayoutParams(width,
                        height, WindowManager.LayoutParams.TYPE_PHONE,
                        WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
                                | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,// 不占用焦点 防止其余应用须要获取焦点的时候没有反应 PixelFormat.TRANSLUCENT);

//这个不能够越过状态栏  可移动可点击
