Android 弹出Dialog时隐藏状态栏和底部导航栏的方法

 上代码

dialog.getwindow().getdecorview().setsystemuivisibility(view.system_ui_flag_hide_navigation);
dialog.getwindow().getdecorview().setonsystemuivisibilitychangelistener(new view.onsystemuivisibilitychangelistener() {
     @override
     public void onsystemuivisibilitychange(int visibility) {
         int uioptions = view.system_ui_flag_layout_stable |
         //布局位于状态栏下方
         view.system_ui_flag_layout_hide_navigation |
         //全屏
         view.system_ui_flag_fullscreen |
         //隐藏导航栏
         view.system_ui_flag_hide_navigation |
         view.system_ui_flag_layout_fullscreen;
         uioptions |= 0x00001000;
         dialog.getwindow().getdecorview().setsystemuivisibility(uioptions);
     }
});

ps:下面看下android dialog弹出时不显示导航栏(沉浸式)

我们的app是全屏沉浸式的，发现activity在设置了全屏后，弹出dialog底部会跳出导航栏虚拟键。具体原因是因为dialog的window抢走了焦点，window 中的 decorview 状态改变导致了退出。

 解决方法，在dialog中：

private void fullscreenimmersive(view view) {
    if (build.version.sdk_int >= build.version_codes.kitkat) {
      int uioptions = view.system_ui_flag_layout_stable
        | view.system_ui_flag_layout_hide_navigation
        | view.system_ui_flag_hide_navigation
        | view.system_ui_flag_immersive_sticky
        | view.system_ui_flag_layout_fullscreen
        | view.system_ui_flag_fullscreen;
      view.setsystemuivisibility(uioptions);
    }
  }

  @override
  public void show() {
    this.getwindow().setflags(windowmanager.layoutparams.flag_not_focusable, windowmanager.layoutparams.flag_not_focusable);
    super.show();
    fullscreenimmersive(getwindow().getdecorview());
    this.getwindow().clearflags(windowmanager.layoutparams.flag_not_focusable);
  }
