android - 如何在android中获取LTE小区位置？

Question

我看到我们有 CDMACellLocation 和 GSMCellLocation 的类，但没有任何特定于 LTE 的类。我可以获得特定于我的电话服务上下文的 LTE 小区位置吗？谢谢!

您可以从 LTE 连接获取信息，对属于 CellInfo 列表的实例进行特定转换。

MobileInfoRecognizer mobileInfoRecognizer = new MobileInfoRecognizer();
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
List<CellInfo> cellInfos = tm.getAllCellInfo();
additional_info = mobileInfoRecognizer.getCellInfo(cellInfos.get(0));

在我的应用程序中，我注意到您只能获取列表中的第一个元素；我向您展示我的自定义类(class):

public class MobileInfoRecognizer {
    public String getCellInfo(CellInfo cellInfo) {
            String additional_info;
            if (cellInfo instanceof CellInfoGsm) {
                CellInfoGsm cellInfoGsm = (CellInfoGsm) cellInfo;
                CellIdentityGsm cellIdentityGsm = cellInfoGsm.getCellIdentity();
                additional_info = "cell identity " + cellIdentityGsm.getCid() + "\n"
                        + "Mobile country code " + cellIdentityGsm.getMcc() + "\n"
                        + "Mobile network code " + cellIdentityGsm.getMnc() + "\n"
                        + "local area " + cellIdentityGsm.getLac() + "\n";
            } else if (cellInfo instanceof CellInfoLte) {
                CellInfoLte cellInfoLte = (CellInfoLte) cellInfo;
                CellIdentityLte cellIdentityLte = cellInfoLte.getCellIdentity();
                additional_info = "cell identity " + cellIdentityLte.getCi() + "\n"
                        + "Mobile country code " + cellIdentityLte.getMcc() + "\n"
                        + "Mobile network code " + cellIdentityLte.getMnc() + "\n"
                        + "physical cell " + cellIdentityLte.getPci() + "\n"
                        + "Tracking area code " + cellIdentityLte.getTac() + "\n";
            } else if (cellInfo instanceof CellInfoWcdma){
                CellInfoWcdma cellInfoWcdma = (CellInfoWcdma) cellInfo;
                CellIdentityWcdma cellIdentityWcdma = cellInfoWcdma.getCellIdentity();
                additional_info = "cell identity " + cellIdentityWcdma.getCid() + "\n"
                        + "Mobile country code " + cellIdentityWcdma.getMcc() + "\n"
                        + "Mobile network code " + cellIdentityWcdma.getMnc() + "\n"
                        + "local area " + cellIdentityWcdma.getLac() + "\n";
            }
            return additional_info;
    }
}

因此，如果被测设备不支持 LTE，您始终可以获取有关其连接的其他相关信息。希望您会发现它有用。
