android 动态显示状态栏和导航栏
开始的时候在网上搜过很多方法，包括
1.通过命令移除SystemUI.apk放到一个文件夹中，然后重新启动com.systemui.SystemUIService这个服务
如果想恢复就把SystemUI.apk移到/system/app/下并且重新启动com.systemui.SystemUIService这个服务。
2.通过不断查杀com.android.systemui(这种暴力的方式不知道有什么后果)
这种方式可以使用如下命令搜出进程号：
process = ps | grep -i "systemui"|busybox awk 'BEGIN {FS=" "} {print $2}'
然后kill $process
不过现象是总是会回到锁屏界面，可以尝试使用定时器每五百毫秒进行一次查杀。
3.还有一种是使用标准的api ，在apk中去使用这个方法去隐藏，不过下拉之后就会显示出状态栏。
猜想：这个要结合禁止下拉一起使用，方才可以。
public void is_full(boolean enable) {
if (enable) {
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN ;
// lp.flags |= WindowManager.LayoutParams.TYPE
getWindow().setAttributes(lp);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
} else {
WindowManager.LayoutParams attr = getWindow().getAttributes();
attr.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setAttributes(attr);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
}
还有一个api是使用如下方法，不过也没有效果，只能实现如图库，视频等的“不触摸全屏显示”：
（具体更多的flag请自行搜索）
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
最后成功的方法是：
在PhoneStatusBar.java中添加广播接受器，动态地add 和 remove 相应的视图。
在其中添加了静止下拉的操作，和禁掉了一些StatusBar的UI，并隐藏了NavigationBar。
也算勉强达到了效果。
完整的补丁如下，本人是在4.4的平台上操作的，仅供参考（不同平台请移植）：
