initParams中的type应该做一下适配

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            windowParams.type = WindowManager.LayoutParams.TYPE_TOAST;
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            windowParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
        }else{
            windowParams.type = WindowManager.LayoutParams.TYPE_PHONE;
        }
