Android关于全屏设置和隐藏状态栏、沉浸式状态栏的总结

1.全屏和推出全屏

   实现全屏 

  getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

  退出全屏

  final WindowManager.LayoutParams attrs = getWindow().getAttributes();      attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);      getWindow().setAttributes(attrs);      getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

2.隐藏状态栏

  getWindow().getDecorView().setSystemUiVisibility(View.INVISIBLE);

  参数：

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。

3.沉浸式状态栏(android4.4开始引进)

  (1).通过SystemBarTintManager

   

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { setTranslucentStatus(true); SystemBarTintManager tintManager = new SystemBarTintManager(this); tintManager.setStatusBarTintEnabled(true); tintManager.setStatusBarTintResource(R.color.color_top_bg);// 通知栏所需颜色 }

        @TargetApi(19)private void setTranslucentStatus(boolean on) {Window win = getWindow();WindowManager.LayoutParams winParams = win.getAttributes();final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;// WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATIONif (on) {winParams.flags |= bits;} else {winParams.flags &= ~bits;}win.setAttributes(winParams);}

   (2).通过顶部增加同ActionBar颜色的view(如果设置后出现tittlebar则在清单文件里面配置activity的style为NoTittlebar)

                Window window = getWindow();window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);ViewGroup decorView = (ViewGroup) window.getDecorView();view = new View(this);view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(this)));view.setBackgroundColor(getResources().getColor(R.color.color_top_bg));decorView.addView(view);
