android6.0 状态栏添加图标 举例Location

增加状态图标步骤如下：

:1： 将图片放在 \frameworks\base\packages\SystemUI\res\drawable-hdpi（实际情况自己选择）

:2：\frameworks\base\core\res\res\values config.xml

添加eyeball

3：\frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone PhoneStatusBarPolicy.java 添加如下（注意名字要与 config.xml中定义的一致）

mService.setIcon(“eyeball”, R.drawable.stat_sys_eyeball, 0,null);

mService.setIconVisibility(“eyeball”, true);
这只是简单的添加一个图标，没有对他进行控制
下面举个我在工作当中实现的一个例子——添加Location图标
添加图片和item我就不贴出来了

这的LocationContorller是SystemUI中就已经定义的了如自己添加的没有控制类，要自己根据实际情况添加。
