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：

方法三：

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。
