解决方法 如果我理解正确,你只想隐藏动作栏？

如果是,请更改此行(将flag_hIDe_navigation更改为0).

private static final int HIDER_FLAGS = 0;// systemUIHIDer.FLAG_HIDE_NAVIGATION;

并将其添加到onCreate调用中：

protected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    getwindow().requestFeature(Window.FEATURE_ACTION_bar);   //new    getActionbar().hIDe();                                   //new    getwindow().setFlags(         WindowManager.LayoutParams.FLAG_FulLSCREEN,WindowManager.LayoutParams.FLAG_FulLSCREEN);    setContentVIEw(R.layout.activity_fullscreen);

之后,如果要显示动作栏,只需从活动中的任意位置调用：

getActionbar().show();
