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：

android:name="com.ysj.demo.MainActivity"

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

android:label="@string/app_name" >

方法三：

true

true

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。
