Android -如何在双卡手机中通过特定的SIM卡拨打电话？

Question

我无法设置呼叫的默认SIM卡。每次在发送ACTION_CALL意图之前，我都会尝试更改系统设置以更改默认的sim，但每次我都会看到sim选择对话框

public class CallUtil {

public static void sendCallIntent(Context context, String number) {
    Intent intent = new Intent(Intent.ACTION_CALL)
            .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setData(Uri.parse("tel:" + number));

    setDefaultSim(context);
    if (ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    context.startActivity(intent);
}

public static void setDefaultSim(Context context) {
    try {
        ContentValues val = new ContentValues();
        List<Integer> sims = getInsertedSIMIds(context);
        val.put("value", sims.get(0));
        context.getContentResolver().update(Uri.parse("content://settings/system"), val, "name='voice_call_sim_setting'", null);

    } catch (Exception e) {

    }

}

public static List<Integer> getInsertedSIMIds(Context context){
    List<Integer> list = new ArrayList<Integer>();
    SubscriptionManager  sm=(SubscriptionManager)context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
    for ( SubscriptionInfo sub: sm.getActiveSubscriptionInfoList()) {
        list.add(sub.getSimSlotIndex());
    }
    return list;
}

}

我的意图是使用Android5.1API通过特定的SIM卡发出呼叫。如果有其他方法，请告诉我。

在API级别22及以上，我们可以在使用SubscriptionManager和TelecomManager进行调用意图时设置sim选择，如下所示。

    //To find SIM ID
    String primarySimId,secondarySimId;
    SubscriptionManager subscriptionManager = (SubscriptionManager) appContext.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
    List<SubscriptionInfo> subList = subscriptionManager.getActiveSubscriptionInfoList(); 
    int index=-1;
    for (SubscriptionInfo subscriptionInfo : subList) {
        index++;
        if(index == 0){
           primarySimId=subscriptionInfo.getIccId();
        }else {
           secondarySimId=subscriptionInfo.getIccId();
        }
    } 

    // TO CREATE PhoneAccountHandle FROM SIM ID  
    TelecomManager telecomManager =(TelecomManager) getSystemService(Context.TELECOM_SERVICE);
    List<PhoneAccountHandle> list = telecomManager.getCallCapablePhoneAccounts();
    PhoneAccountHandle primaryPhoneAccountHandle,secondaryPhoneAccountHandle;
    for(PhoneAccountHandle phoneAccountHandle:list){
       if(phoneAccountHandle.getId().contains(primarySimId)){
         primaryPhoneAccountHandle=phoneAccountHandle;
        }
       if(phoneAccountHandle.getId().contains(secondarySimId)){
         secondaryPhoneAccountHandle=phoneAccountHandle;                     
        }
    }

    //To call from SIM 1
    Uri uri = Uri.fromParts("tel",number, "");
    Bundle extras = new Bundle();  extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE,primaryPhoneAccountHandle);
    telecomManager.placeCall(uri, extras);

    //To call from SIM 2
    Uri uri = Uri.fromParts("tel",number, "");
    Bundle extras = new Bundle();  extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE,secondaryPhoneAccountHandle);
    telecomManager.placeCall(uri, extras);

双卡并不是Android SDK的官方支持。我建议你捕获logcat并使用系统拨号器进行特定的sim呼叫，找出关于sim卡的意图格式。

更新

从api的22级来看，sdk支持双卡link，但我在SDK文档中找不到双卡的ACTION_CALL intent格式。

True-caller app已经能够添加一个按钮，用于选择特定的SIM卡来发送或接收语音和文本消息。我尝试过5.1中引入的SubscriptionManager应用程序接口，但仍然没有得到任何更改。
