实现隐藏标题栏 + 全屏 + 常亮

1、实现方式 1

（1）演示

1. 在themes.xml文件进行如下配置

<resourcesxmlns:tools="http://schemas.android.com/tools"><style...>... <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item></style></resources>

2. Activity 代码

publicclassMainActivityextendsAppCompatActivity{@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);setContentView(R.layout.activity_main);}}

（2）解读

1. 隐藏标题栏（ActionBar）

<itemname="windowActionBar">false</item><itemname="windowNoTitle">true</item>

2. 隐藏原生标题栏

requestWindowFeature(Window.FEATURE_NO_TITLE);

3. 设置全屏，隐藏状态栏

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

4. 保持屏幕常亮

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
