Android五种隐藏状态栏和标题栏的方法
方法一：
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 隐藏标题栏 requestWindowFeature(Window.FEATURE_NO_TITLE); // 隐藏状态栏 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_main); } }
方法二：
<!-- 同时隐藏状态栏和标题栏 --> <activity android:name="com.ysj.demo.MainActivity" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
方法三：
<!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <!-- 隐藏状态栏 --> <item name="android:windowFullscreen">true</item> <!-- 隐藏标题栏 --> <item name="android:windowNoTitle">true</item> </style>
方法四：动态显示隐藏状态栏
//隐藏状态栏 WindowManager.LayoutParams lp = context.getWindow().getAttributes(); lp.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; context.getWindow().setAttributes(lp); //显示状态栏 WindowManager.LayoutParams attr = context.getWindow().getAttributes(); attr.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN); context.getWindow().setAttributes(attr);
方法五：动态显示隐藏状态栏
View类提供了setSystemUiVisibility和getSystemUiVisibility方法，这两个方法实现对状态栏的动态显示或隐藏的操作，以及获取状态栏当前可见性。
setSystemUiVisibility方法传入的实参分析：
setSystemUiVisibility(int visibility)方法可传入的实参为：
1. View.SYSTEM_UI_FLAG_VISIBLE：显示状态栏，
Activity不全屏显示(恢复到有状态的正常情况)。
2. View.INVISIBLE：隐藏状态栏，同时Activity会伸展全屏显示。
3. View.SYSTEM_UI_FLAG_FULLSCREEN：Activity全屏显示，且状态栏被隐藏覆盖掉。
4. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN：Activity全屏显示，但状态栏不会被隐藏覆盖，状态栏依然可见，Activity顶端布局部分会被状态遮住。
5. View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION：效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
6. View.SYSTEM_UI_LAYOUT_FLAGS：效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
7. View.SYSTEM_UI_FLAG_HIDE_NAVIGATION：隐藏虚拟按键(导航栏)。有些手机会用虚拟按键来代替物理按键。
8. View.SYSTEM_UI_FLAG_LOW_PROFILE：状态栏显示处于低能显示状态(low profile模式)，状态栏上一些图标显示会被隐藏。
