分析思路：

状态栏icon对应 StatusBarIconView，找到其中

setVisibility(icon.visible && !mBlocked ? VISIBLE : GONE); 可以看到有个 mBlocked，有的显示有的不显示，那应该就是被黑了。

StatusBarIconControllerImpl.java
onTuningChanged(String key, String newValue) {
mIconHideList.addAll(StatusBarIconController.getIconHideList(mContext, newValue));

addSystemIcon(int index, StatusBarIconHolder holder) {
	boolean hidden = mIconHideList.contains(slot);
	l.onIconAdded(viewIndex, slot, hidden, holder));

StatusBarIconController.java
addHolder(int index, String slot, boolean blocked, StatusBarIconHolder holder) {
if (mBlockList.contains(slot)) {
blocked = true;
}
switch (holder.getType()) {
case TYPE_ICON:
return addIcon(index, slot, blocked, holder.getIcon());

被黑有两种方式，均在 StatusBarIconController 中过滤

第一种看到上面直接传递的 blocked，通过 config.xml 中配置

frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\StatusBarIconController.java

    static ArraySet<String> getIconHideList(Context context, String hideListStr) {
        ArraySet<String> ret = new ArraySet<>();
        String[] hideList = hideListStr == null
            ? context.getResources().getStringArray(R.array.config_statusBarIconsToExclude)
            : hideListStr.split(",");
        for (String slot : hideList) {
            if (!TextUtils.isEmpty(slot)) {
                ret.add(slot);
            }
        }
        return ret;
    }

可以看到耳机(headset)和旋转(rotate)被黑了

第二种，通过 mBlockList 进行添加,静音(volume)和闹钟(alarm_clock)和call_strength被黑了

frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\StatusBarIconController.java

	public void setBlockList(@Nullable List<String> blockList) {
		mBlockList.clear();
		if (blockList == null || blockList.isEmpty()) {
			return;
		}

		mBlockList.addAll(blockList);
	}
