android facebook sdk 4.2 open graph 故事和 map

Question

我正在尝试使用 facebook android sdk 版本 4.2 分享健身类(class)的开放图故事和位置，

我想要这样的东西:

但是 map 没有显示

基本上我的代码是这样的:

    ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
    .putString("og:type", "fitness.course")
    .putString("og:title", "Sample Course")
    .putString("og:description", "This is a sample course.")
    .putInt("fitness:duration:value", 100)
    .putString("fitness:duration:units", "s")
    .putInt("fitness:distance:value", 12)
    .putString("fitness:distance:units", "km")
    .putInt("fitness:speed:value", 5)
    .putString("fitness:speed:units", "m/s");

    ArrayList<ShareOpenGraphObject> metrics = new ArrayList<ShareOpenGraphObject>();
    ShareOpenGraphObject.Builder metric1 = new ShareOpenGraphObject.Builder();
    String timestamp1 = dateFormat.format(new Date(realDateTime1));
    metric1.putDouble("fitness:metrics:location:latitude", latitude1);
    metric1.putDouble("fitness:metrics:location:longitude",longitude1);
    metric1.putString("fitness:metrics:timestamp",timestamp1);
    metrics.add(metric1.build());
    ShareOpenGraphObject.Builder metric2 = new ShareOpenGraphObject.Builder();
    String timestamp2 = dateFormat.format(new Date(realDateTime2));
    metric2.putDouble("fitness:metrics:location:latitude", latitude2);
    metric2.putDouble("fitness:metrics:location:longitude",longitude2);
    metric2.putString("fitness:metrics:timestamp",timestamp2);
    metrics.add(metric2.build());

    .....

    object.putObjectArrayList("fitness:metrics", metrics);

    ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
     .setActionType("fitness.runs")
     .putObject("fitness:course", object.build())
     .putString("fitness:start_time", startTime)
     .putString("fitness:end_time", endTime)
     .build();

    ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
     .setPreviewPropertyName("fitness:course")
     .setAction(action)
     .build();

我尝试了几次但都没有成功，例如，如果我不使用上面显示的指标数组，而是将 fitness:metrics:location:* 直接放在原始对象构建器上， map 将显示为一个位置。提示？

Answer 1

我有一个类似的问题，在我的例子中，我有一个托管健身类(class)的网络后端，我通过在 ShareOpenGrapAction 中设置健身类(class)的 url 解决了这个问题。

在网络后端中，健身类(class)是使用此处所述的引用创建的:https://developers.facebook.com/docs/opengraph/guides/fitness

在应用程序中

ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
        .setActionType("fitness.runs")
        .putString("fitness:course", url)
        .build();

ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
        .setPreviewPropertyName("fitness:course")
        .setAction(action)
        .build();

比起表演

if (shareDialog.canShow(ShareOpenGraphContent.class)) {
    shareDialog.show(content);
}

希望这对您有所帮助!
