Android手机搜网列表名称显示流程

搜网列表显示由 NetworkSettingList.java 的getNetworkTitle方法实现
private String getNetworkTitle(OperatorInfo ni) {
if (!TextUtils.isEmpty(ni.getOperatorAlphaLong())) {
return ni.getOperatorAlphaLong();
} else if (!TextUtils.isEmpty(ni.getOperatorAlphaShort())) {
return ni.getOperatorAlphaShort();
} else {
return ni.getOperatorNumeric();
}
}

OperatorInfo 由 networksListLoaded()传过来

/**
* networksListLoaded has been rewritten to take an array of
* OperatorInfo objects and a status field, instead of an
* AsyncResult. Otherwise, the functionality which takes the
* OperatorInfo array and creates a list of preferences from it,
* remains unchanged.
