營養數據谷歌適合

Question

閱讀營養數據有延遲嗎？我插入的營養數據，我想讀他們，但數據點的尺寸仍然等於0 ...

我插入這樣的數據：

long now = System.currentTimeMillis(); 

DataSource nutritionSource = new DataSource.Builder() 
      .setAppPackageName(getApplicationContext().getPackageName()) 
      .setType(DataSource.TYPE_RAW) 
      .setDataType(DataType.TYPE_NUTRITION) 
      .build(); 

DataSet dataSet = DataSet.create(nutritionSource); 

DataPoint dataPoint = DataPoint.create(nutritionSource); 
dataPoint.setTimestamp(now, TimeUnit.MILLISECONDS); 
dataPoint.getValue(Field.FIELD_FOOD_ITEM).setString(name_food); 
dataPoint.getValue(Field.FIELD_NUTRIENTS).setKeyValue(Field.NUTRIENT_CALORIES, calorie_food); 
dataPoint.getValue(Field.FIELD_NUTRIENTS).setKeyValue(Field.NUTRIENT_SUGAR,sugar_food); 
dataPoint.getValue(Field.FIELD_NUTRIENTS).setKeyValue(Field.NUTRIENT_TOTAL_FAT,fat_food); 
dataPoint.getValue(Field.FIELD_NUTRIENTS).setKeyValue(Field.NUTRIENT_PROTEIN,protein_food); 
dataPoint.getValue(Field.FIELD_MEAL_TYPE).setInt(Field.MEAL_TYPE_UNKNOWN); 


dataSet.add(dataPoint); 

然後，我想看他們這樣的：

DataReadRequest readRequest = new DataReadRequest.Builder() 
      .aggregate(DataType.TYPE_NUTRITION, DataType.AGGREGATE_NUTRITION_SUMMARY) 
      .bucketByTime(1, TimeUnit.DAYS) 
      .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS) 
      .build(); 

    // Invoke the History API to fetch the data with the query and await the result of 
    // the read request. 
    DataReadResult dataReadResult = 
      Fitness.HistoryApi.readData(mClient, readRequest).await(1, TimeUnit.MINUTES); 

    if(dataReadResult.getStatus().isSuccess()){ 
     Log.i("TAG","isSuccess to read nutrition data"); 
     if(dataReadResult.getDataSet(DataType.TYPE_NUTRITION).getDataPoints().size() > 0){ 
      Log.i("TAG","calorie : "+dataReadResult.getDataSet(DataType.TYPE_NUTRITION).getDataPoints().get(0).getValue(Field.FIELD_CALORIES)); 
     } 
    } 

我想獲得當天的所有數據點，並與他們的工作，但我不知道如何？

感謝，

不知道這仍然是你的問題，但試圖利用它來獲取每一個聚合數據的「桶」。

 List<Bucket> buckets = dataReadResult.getBuckets(); 
     for (int a = buckets.size() - 1; a > -1; a--) { 
      Bucket bucket = buckets.get(a); 
      for (DataSet dataSet : bucket.getDataSets()) { 
       if(dataSet.getDataType().getName().equals(DataType.TYPE_NUTRITION.getName())){ 
        for (DataPoint dp : dataSet.getDataPoints()) { 
         Log.i(TAG, "Data point:"); 
         Log.i(TAG, "\tType: " + dp.getDataType().getName()); 
         for(Field field : dp.getDataType().getFields()) { 
          Log.i(TAG, "\tField: " + field.getName() + 
            " Value: " + dp.getValue(field)); 
         } 
        } 
       } 
      } 
     }
