Android五种隐藏状态栏和标题栏的方法

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。
