使用 google fit android api 读取数据时获取 "Task is not yet complete error"

Question

我正在学习 Android，我的任务是使用 Google 适合步数 API 检索步数数据。但是，我不断收到 "Task is not yet complete" 错误。我不确定

这是我的那部分代码：

private List<Fitness> readHistoryDataFromGoogle() {
    DataReadRequest readRequest = createDataReadRequest();
    Task<DataReadResponse> response = com.google.android.gms.fitness.Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this)).readData(readRequest);
    DataReadResponse responses  = response.getResult();
    List <Fitness> fitnessItems = parseFitness(responses);
    return fitnessItems;
}


private List<Fitness> parseFitness(DataReadResponse dataReadResponse) {
    List<com.example.mentalhealthapp.Fitness> fitnessItems = new ArrayList<>();
    for (Bucket bucket : dataReadResponse.getBuckets()) {
        for (DataSet set : bucket.getDataSets()) {
            for (DataPoint dataPoint : set.getDataPoints()) {
                int numSteps = dataPoint.getValue(Field.FIELD_STEPS).asInt();
                long startDateTime = dataPoint.getStartTime(TimeUnit.MILLISECONDS);
                long endDateTime = dataPoint.getEndTime(TimeUnit.MILLISECONDS);
                fitnessItems.add(new com.example.mentalhealthapp.Fitness(numSteps, startDateTime, endDateTime));
            }
        }
    }
    return fitnessItems;
}

非常感谢您的帮助！

您遇到了这个问题，因为 API 请求（服务调用）是 Asynchronous，它们不会立即完成 return 数据，您不能运行它们像其他代码一样逐行显示。您必须等待该响应完成，然后才能访问它 return 的数据。从文档中它告诉你它是一个 REST api：

简要查看文档 https://developers.google.com/android/reference/com/google/android/gms/fitness/RecordingClient 建议您在数据可用时查看它以显示数据。
