一：把NavigationBa隐藏掉

Window window = getWindow();
WindowManager.LayoutParams params = window.getAttributes();
params.systemUiVisibility = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|View.SYSTEM_UI_FLAG_IMMERSIVE;
window.setAttributes(params);

在setContentView();方法之前执行。

二：修改NavigationBar背景颜色以及NavigationBar的按键颜色

//修改NavigationBar背景颜色
public static void setNavbarColor(Activity activity){
Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setNavigationBarColor(activity.getResources().getColor(R.color.colorAccent));
}

//修改NavigationBar按键颜色
public static void setLightNavigationBar (Activity activity) {
int vis = activity.getWindow().getDecorView().getSystemUiVisibility();
vis |= View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR; //黑色
//vis &= ~ View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR; //白色
activity.getWindow().getDecorView().setSystemUiVisibility(vis);
}
