systemui状态栏添加新图标

状态栏右侧添加新图标

需求描述

在状态栏右边添加一个自定义图标，根据广播更新图标。

代码实现

framework部分修改
frameworks/base/core/res/res/values/config.xml最上方config_statusBarIcons。原生注释写的很清楚了，用不要钱的翻译翻译一下：
不要翻译。
定义右侧图标的插槽。
也就是状态栏里不是通知的图标
1、config_statusBarIcons数组里添加自定义图标xiguatong
2、在下方添加string xiguatong
frameworks/base/core/res/res/values/config.xml中config_statusBarIcons的顺序表示右侧状态栏图标的顺序，我们在电量图标前面加了一个xiguatong

<!-- Do not translate. Defines the slots for the right-hand side icons.  That is to say, the
         icons in the status bar that are not notifications. -->

frameworks/base/core/res/res/values/symbols.xml中添加xiguatong id，不然引用不到资源

  <java-symbol type="string" name="status_bar_xiguatong" />
  <java-symbol type="string" name="status_bar_battery" />

systemui部分
vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java

private final StatusBarIconController mIconController;//状态栏图标控制器
//自己加的西瓜桶图标
private final String mXiGuaTong;
private boolean mXiGuaTongVisible;
@Inject
public PhoneStatusBarPolicy(...){
	...
	//
	mXiGuaTong = resources.getString(com.android.internal.R.string.status_bar_xiguatong);
	mXiGuaTongVisible = true;
	...
}
public void init() {
	...
	//xiGuaTong:字符串，图片，按钮描述
	mIconController.setIcon(mXiGuaTong, R.drawable.stat_sys_xiguatong,null);
	//设置图片可见不可见:字符串，Boolean值
	mIconController.setIconVisibility(mXiGuaTong, mXiGuaTongVisible);
	...
}

以上，就可以在状态栏右侧添加新图标。

遗留问题

1、图标是怎么加到状态栏右边的，完整流程？
2、状态栏左边怎么加图标？
3、状态栏、下拉状态栏、2次下拉状态栏、锁屏、这几种状态下状态栏图标会有变化，是哪里控制的？
