客户要求系统提供接口实现该功能，通过广播方式实现，
验证网友方案记录如下，对网友分享非常感谢：
代码如下;

App添加按钮实现函数：
public void showbar(View view) {Intent i = new Intent("car.intent.systemui.shownavigation");sendBroadcast(i);Intent status = new Intent("car.intent.systemui.showstatusbar");sendBroadcast(status);
}public void hidebar(View view) {Intent i = new Intent("car.intent.systemui.hidenavigation");sendBroadcast(i);Intent status = new Intent("car.intent.systemui.hidestatusbar");sendBroadcast(status);
}
当然可以通过app实现隐藏app api也可以，但是发现触摸屏幕状态栏能够显示出来；有些问题，方法也写出来：
在Activity的onCreate方法中添加如下方法即可
Window window = getWindow();
WindowManager.LayoutParams params = window.getAttributes();
params.systemUiVisibility = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|View.SYSTEM_UI_FLAG_FULLSCREEN|View.SYSTEM_UI_FLAG_IMMERSIVE;
window.setAttributes(params);
