从google fit读取体重

Question

我无法从Google健身中读取体重。 当我向Google Fit请求体重时，我只获得体重字段的名称（体重），但DataPoints大小为0.哪里出错？

代码：

DataReadRequest dataReadRequest = queryFitnessData(); 

DataReadResult dataReadResult = Fitness.HistoryApi.readData(getApiClient(), dataReadRequest) 
       .await(1000, TimeUnit.MILLISECONDS); 
//////// 
private static DataReadRequest queryFitnessData() { 
    Calendar calendar = Calendar.getInstance(); 
    Date date = new Date(); 
    calendar.setTime(date); 
    long endTime = calendar.getTimeInMillis(); 
    calendar.add(Calendar.YEAR, -1); 
    long startTime = calendar.getTimeInMillis(); 

    DataReadRequest dataReadRequest = new DataReadRequest.Builder() 
      .read(DataType.TYPE_WEIGHT) 
      .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS) 
      .build(); 

    return dataReadRequest; 
} 

Answer 1

你有没有加入你specified.Can的TIMERANGE重量尝试

DataReadRequest dataReadRequest = new DataReadRequest.Builder() 
      .read(DataType.TYPE_WEIGHT) 
      .setTimeRange(1, endTime, TimeUnit.MILLISECONDS) 
      .setLimit(1) 
      .build();
