java – android全屏活动并隐藏键栏

我是 android编程的新手！
我想要像Hill climb Racing这样的全屏图像(如下所示)

我尝试使用

requestwindowFeature(Window.FEATURE_NO_TITLE);
getwindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

但它只是消失动作栏,我想消失动作栏和Android默认键栏(主页按钮,后面和另一个)

解决方法

如果你的目标是Android 4.0及更高版本

View decorView = getwindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYstem_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher,but as
// a general rule,you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYstem_UI_FLAG_HIDE_NAVIGATION
              | View.SYstem_UI_FLAG_FULLSCREEN;
decorView.setsystemUIVisibility(uiOptions);
