Android全屏界面，弹窗显示时会拉起导航栏

问题描述

在一个全屏界面，使用WindowManager显示弹窗后，会拉起底部导航栏

解决

尝试发现设置WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE属性可以正确隐藏导航栏

WindowManager.LayoutParams windowLayoutParams = getWindow().getAttributes();
windowLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
 | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
getWindow().setAttributes(windowLayoutParams);

可主动隐藏systemui代码

getWindow().getDecorView().setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            );
