Android五种隐藏状态栏和标题栏的方法（隐藏状态栏、标题栏方法汇总）

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。
