android - 如何通过intent-filter和action.SEND_MULTIPLE接收多张电子名片

Question

我尝试通过 Android 联系人应用中的共享功能在我的应用中接收多个联系人，但我只收到第一个联系人，我从未收到 ACTION_SEND_MULTIPLE 的 action >.

我用过https://developer.android.com/training/sharing/receive作为灵感。

AndroidManifest:

<activity android:name=".ShareActivity">
    <intent-filter>
        <action android:name="android.intent.action.SEND" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="text/x-vcard" />
    </intent-filter>
    <intent-filter>
        <action android:name="android.intent.action.SEND_MULTIPLE" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="text/x-vcard" />
    </intent-filter>
</activity>

分享 Activity :

Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();

if (Intent.ACTION_SEND.equals(action) && type != null) {
    // My code always pass here because action is always equals to ACTION_SEND even with several contacts selectionned
    if ("text/x-vcard".equals(type)) {
        handleSendContact(intent);
    }
} else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
    if ("text/x-vcard".equals(type)) {
        handleSendMultiContact(intent);
    }
}

private void handleSendContact(Intent intent) {
    Uri uri = intent.getParcelableExtra(Intent.EXTRA_STREAM);
    // use uri to get lookupkey...
}

private void handleSendMultiContact(Intent intent) {
    ArrayList<Uri> contactUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
    for (Uri uri : contactUris) {
        // use uri to get lookupkey...
    }
}

共享一个联系人，一切工作正常，但是当我选择两个或更多联系人时，我收到的操作仍然是 ACTION_SEND 而不是 ACTION_SEND_MULTIPLE 并且我只收到第一个选择的联系人接触。我的目标是接收在 Android 联系人应用程序中选择的所有联系人。

Answer 1

简短版本:

ACTION_SEND_MULTIPLE 绝不会与联系人/vCard 共享一起使用。相反，ACTION_SEND 始终与包含多个联系人的数据和包含由 : 分隔的多个 LOOKUP_KEY 的 uri 一起使用。

正如您在上面所观察到的，在 Uri 上共享两个联系人结果，两个 LOOKUP_KEY 之间用 %3A(ASCII 中的冒号)分隔。我在PeopleActivity.java中找到了这样做的aosp代码了解详情。

因此我可以利用该代码块来利用多个联系人共享:

if (Intent.ACTION_SEND.equals(action) && type != null) {
    Log.d("type", "type: " + type);
    if (type.equals("text/x-vcard")) {
        handleSendContact(intent);
    }
}

void handleSendContact(Intent intent) {
    Uri contactUri = intent.getParcelableExtra(Intent.EXTRA_STREAM);
    if (contactUri != null) {
        //  getLastPathSegment() decodes "%3A" to ":", so split must be done on colon
        String[] lookupKeys = contactUri.getLastPathSegment().split(":");
        for (String lookupKey : lookupKeys) {
            // Query contact with lookup key
        }
    }
}
