Android中隐藏状态栏和标题栏的方法汇总（隐藏状态栏、标题栏的五种方法）

  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。

            ".system_ui_flag_layout_fullscreen \n view.system_ui_flag_layout_hide_navigation");  
        break;  
      case r.id.button5:  
        mmain.setsystemuivisibility(view.system_ui_flag_layout_fullscreen);  
        mtextview.settext("activity全屏显示，状态栏透明\nview.system_ui_flag_layout_hide_navigation");  
        break;  
      case r.id.button6:  
        mmain.setsystemuivisibility(view.system_ui_flag_hide_navigation);

        mtextview.settext("状态栏低能显示，有一些会被隐藏\nview.system_ui_flag_low_profile");  
        break;  
            default:  
        break;  
    }  
  }  
} 

下面看下 隐藏标题栏和底部操作栏,可上下滑动显示代码

@override
public void onwindowfocuschanged(boolean hasfocus)
{
super.onwindowfocuschanged(hasfocus);
if (hasfocus)
{
view decorview = that.getwindow().getdecorview();
decorview.setsystemuivisibility(view.system_ui_flag_hide_navigation | view.system_ui_flag_immersive_sticky | view.system_ui_flag_fullscreen);
}
}
