獲得雙網手機編程網絡運營商的完整列表

Question

如果手機是雙SIM卡或相鄰網絡運營商名稱的整個列表，我需要獲取網絡運營商名稱。當我谷歌搜索我發現網絡運營商名稱是這樣的

TelephonyManager tManager = (TelephonyManager) getBaseContext() 
     .getSystemService(Context.TELEPHONY_SERVICE); 

// Get carrier name (Network Operator Name) 
String carrierName = tManager.getNetworkOperatorName(); 

但這不會爲我工作。我怎樣才能做到這一點。如果不建議我一些解決方案。謝謝

幸運的是，有幾種原生解決方案。

對於API> = 17：

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 

// Get information about all radio modules on device board 
// and check what you need by calling #getCellIdentity. 

final List<CellInfo> allCellInfo = manager.getAllCellInfo(); 
for (CellInfo cellInfo : allCellInfo) { 
    if (cellInfo instanceof CellInfoGsm) { 
     CellIdentityGsm cellIdentity = ((CellInfoGsm) cellInfo).getCellIdentity(); 
     //TODO Use cellIdentity to check MCC/MNC code, for instance. 
    } else if (cellInfo instanceof CellInfoWcdma) { 
     CellIdentityWcdma cellIdentity = ((CellInfoWcdma) cellInfo).getCellIdentity(); 
    } else if (cellInfo instanceof CellInfoLte) { 
     CellIdentityLte cellIdentity = ((CellInfoLte) cellInfo).getCellIdentity(); 
    } else if (cellInfo instanceof CellInfoCdma) { 
     CellIdentityCdma cellIdentity = ((CellInfoCdma) cellInfo).getCellIdentity(); 
    } 
} 

在AndroidManifest添加權限：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
</manifest> 

爲了讓網絡運營商可以檢查MCC和MNC碼：

• https://en.wikipedia.org/wiki/Mobile_country_code（一般信息）。
• https://clients.txtnation.com/hc/en-us/articles/218719768-MCCMNC-mobile-country-code-and-mobile-network-code-list-（相當充分和最新的運營商名單）。

對於API> = 22：

final SubscriptionManager subscriptionManager = SubscriptionManager.from(context); 
final List<SubscriptionInfo> activeSubscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList(); 
for (SubscriptionInfo subscriptionInfo : activeSubscriptionInfoList) { 
    final CharSequence carrierName = subscriptionInfo.getCarrierName(); 
    final CharSequence displayName = subscriptionInfo.getDisplayName(); 
    final int mcc = subscriptionInfo.getMcc(); 
    final int mnc = subscriptionInfo.getMnc(); 
    final String subscriptionInfoNumber = subscriptionInfo.getNumber(); 
} 

對於API> = 23。要檢查手機是雙卡/三卡/多卡：

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
if (manager.getPhoneCount() == 2) { 
    // Dual sim 
}
