使用双SIM卡设备中的指定SIM卡拨打电话

问题描述：

过去几天来我一直在寻找这个，我知道:

I have been searching for this from past few days and I came to know that:

"Android暂时不支持双SIM卡.这是制造商的自定义修改，并且没有公共API来控制它."

"Dual SIM is not supported in Android out of the box. It is a custom modification by manufacturers, and there is no public API to control it."

下面的链接中提供了一个解决方案，但不适用于我的手机Samsung Galaxy S4 Mini.

There is a solution provided in the below link but its not working on my phone Samsung Galaxy S4 Mini.

从第二个SIM卡拨打电话

我还找到了此链接，该链接非常有用.

I also found this link, which I found very informative.

现在，我知道使用以下代码，我可能有幸能使其正常工作:

Now I know that using the following code, I might have a chance to get lucky to make it working:

Intent callIntent = new Intent(Intent.ACTION_CALL)
                .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        callIntent.setData(Uri.parse("tel:" + phone));
        context.startActivity(callIntent);
callIntent.putExtra("com.android.phone.extra.slot", 0); //For sim 1
and
callIntent.putExtra("com.android.phone.extra.slot", 1); //For sim 2

对此我不确定，但是我有一个问题.

I am not sure about this, but I have a question.

在"SIM卡管理器"部分下的设置"中，当我必须为语音呼叫选择首选的SIM卡时，我有四个选项:

In Settings under the SIM Card Manager section, when I have to choose a preferred SIM card for Voice Call, I get four options:

当前网络
总是问
SIM 1
SIM 2

当我选择始终询问"选项时，在拨打电话之前，总是要求我选择对话框中显示的SIM卡进行通话.我的问题是，我可以在我的应用程序中利用此功能吗?我按此按钮可以拨打电话，但它总是问我选择总是询问"选项时的方式.

When I choose Ask Always option then before making a call I am always asked for choosing a SIM Card, displayed in a Dialog Box, to make the call. My question is can I exploit this thing in my App where I press a button to make a call but it always asks me the same way it does when I chose Ask Always option.

很抱歉，我把这个问题冗长了，但是我认为这是必需的.请提前提供帮助和感谢.

I am sorry, I made this question lengthy, but I think it required it. Please help and big thanks in advance.

每次我按任意按钮时，该如何实现(类似于设置"中的总是询问"选项):

How can I achieve this, everytime I press any button (Kind of similar to Ask Always option in Settings) :

代码:

private final static String simSlotName[] = {
        "extra_asus_dial_use_dualsim",
        "com.android.phone.extra.slot",
        "slot",
        "simslot",
        "sim_slot",
        "subscription",
        "Subscription",
        "phone",
        "com.android.phone.DialingMode",
        "simSlot",
        "slot_id",
        "simId",
        "simnum",
        "phone_type",
        "slotId",
        "slotIdx"
};


Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "any number"));
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.putExtra("com.android.phone.force.slot", true);
    intent.putExtra("Cdma_Supp", true);
    //Add all slots here, according to device.. (different device require different key so put all together)
    for (String s : simSlotName)
        intent.putExtra(s, 0); //0 or 1 according to sim.......

    //works only for API >= 21
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
        intent.putExtra("android.telecom.extra.PHONE_ACCOUNT_HANDLE", (Parcelable) " here You have to get phone account handle list by using telecom manger for both sims:- using this method getCallCapablePhoneAccounts()");

    context.startActivity(intent);
