Samsung Galaxy S8 full screen mode
提问by Barmaley Red Star
Latest Samsung's smartphone has interesting feature called full screen(or in marketing terms infinity display). In this mode app covers also part of display where home/back buttons are. Usual apps don't cover this area, leaving it black. But Samsung's native ones cover this area.
最新的三星智能手机具有有趣的功能，称为全屏（或在营销术语中为无限显示）。在这种模式下，应用程序还覆盖了主页/后退按钮所在的部分显示。通常的应用程序不覆盖此区域，将其保留为黑色。但三星的原生产品涵盖了这一领域。
Question: how to achieve this effect? I mean what kind of manifest declaration or programmatic call (possibly Samsung's legacy API) should I use?
问题：如何实现这个效果？我的意思是我应该使用什么样的清单声明或编程调用（可能是三星的遗留 API）？

To enable new Samsung Galaxy S8 and LG G6 full screen support add to the AndroidManifest.xml under the <application>element:
要启用新的三星 Galaxy S8 和 LG G6 全屏支持，请添加到 AndroidManifest.xml<application>元素下：
<meta-data android:name="android.max_aspect" android:value="2.1" />
Where value of 2.1 is aspect ratio 18.5:9 (By default your App defaults to maximum ratio for 16:9 - 1.86). More info in: Android Blog.
其中 2.1 的值是纵横比 18.5:9（默认情况下，您的应用默认为 16:9 - 1.86 的最大比例）。更多信息请访问：Android 博客。
Alternatively, you can set the following attribute for Application or Activity:
或者，您可以为应用程序或活动设置以下属性：
android:resizeableActivity="true"
Because the documentations states (link):
因为文档说明（链接）：
You do not need to set a maximum aspect ratio if an activity's android:resizeableActivity attribute is set to true. If your app targets API level 24 or higher, this attribute defaults to true.
如果 Activity 的 android:resizeableActivity 属性设置为 true，则不需要设置最大纵横比。如果您的应用面向 API 级别 24 或更高级别，则此属性默认为 true。

to get full-screen you must overide onWindowFocusChangedmethod and create decorViewobject and add System_UI flags into it..
要获得全屏，您必须覆盖onWindowFocusChanged方法并创建装饰视图对象并将 System_UI 标志添加到其中..
@Override
public void onWindowFocusChanged(boolean hasFocus){
super.onWindowFocusChanged(hasFocus);
View decorView = getWindow().getDecorView();
if(hasFocus){
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
|View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY // this flag do=Semi-transparent bars temporarily appear and then hide again
|View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN // Make Content Appear Behind the status Bar
|View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION // it Make Content Appear Behind the Navigation Bar
|View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
|View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
}
}
