导航sdk还开放了导航中部分按钮和界面的显示隐藏功能。详细的设置项可参考类参考文档IBNProfessionalNaviSetting，部分示例如下：

实现方法：

Bundle params = new Bundle();
params.putBoolean(BNaviCommonParams.ProGuideKey.IS_SUPPORT_FULL_SCREEN, true);
BNGuideConfig config = new BNGuideConfig.Builder()
       // 导航工具栏上方view
       .addAboveBottomView(new IBNRouteGuideManager.NaviAddViewCallback() {
        @Override
        public int getViewHeight() {
            return 100;
        }
        @Override
        public View getAddedView() {
          TextView textView = new TextView(BNDemoCustomGuideActivity.this);
          textView.setBackgroundColor(Color.parseColor("#ffff00"));
          textView.setText("导航工具栏上方自定义空间");
          textView.setGravity(Gravity.CENTER);
          textView.setTextColor(Color.parseColor("#000000"));
          FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(
                  ViewGroup.LayoutParams.MATCH_PARENT, 100);
          textView.setLayoutParams(lp);
          return textView;
       }
    })
    // 导航工具栏view
    .addBottomBarView(new IBNRouteGuideManager.NaviAddViewCallback() {
        @Override
        public View getAddedView() {
            TextView textView = new TextView(BNDemoCustomGuideActivity.this);
            textView.setBackgroundColor(Color.parseColor("#ff00ff"));
            textView.setText("导航工具栏自定义空间");
            textView.setGravity(Gravity.CENTER);
            textView.setTextColor(Color.parseColor("#000000"));
            FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(
                    ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
            textView.setLayoutParams(lp);
            return textView;
        }
    })
    // 导航工具栏下方view
    .addBelowBottomView(new IBNRouteGuideManager.NaviAddViewCallback() {
        @Override
        public int getViewHeight() {
            return 100;
        }

        @Override
        public View getAddedView() {
          TextView textView = new TextView(BNDemoCustomGuideActivity.this);
          textView.setBackgroundColor(Color.parseColor("#00ffff"));
          textView.setText("导航工具栏下方自定义空间");
          textView.setGravity(Gravity.CENTER);
          textView.setTextColor(Color.parseColor("#000000"));
          FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(
                  ViewGroup.LayoutParams.MATCH_PARENT, 100);
          textView.setLayoutParams(lp);
          return textView;
        }
    })
    .params(params)
    .build();
BaiduNaviManagerFactory.getRouteGuideManager().onCreate(getActivity(), config);
