如何将 Android 传感器的数据写入稍后可以访问的文档？
因此，我正在 Android Galaxy Tab 10.1 上创建一个使用其加速计和陀螺仪的项目。这里的步骤之一是收集大量数据并确定其准确性和漂移。为此，我需要移动设备并允许传感器获取读数，然后获取这些读数并对它们进行一些分析。
我承认，这样做的原始方法是将每个读数作为错误发送到日志，从 Eclipse 复制日志，将其粘贴到记事本中，然后对其进行格式化，从而消除其他不需要的错误和时间戳。这种方法不太好，如果列表太长，Eclipse 中的日志会删除旧的日志条目，这意味着我只能查看大约 30 秒的数据。
我需要比这更多的时间，所以我想了几种方法来解决这个问题：
- 如果我能以某种方式将读数直接从 Android 写入我使用的计算机上的文档，那就可以解决我的所有问题。
- 如果我可以将读数写入 Android 上的一个文件，该文件可以保存并稍后传输到计算机，那也可以
So I'm creating a project on an Android Galaxy Tab 10.1 that uses its accelerometers and gyroscopes. One of the steps here is to collect alot of data and determine its accuracy and drift. To do this I need to move the device and allow the sensors to get their readings, and then take those readings and put them through some analysis.
My admittedly primitive way of doing this is to send each reading as an error to the log, copy the log from Eclipse, paste it in notepad, and format it, getting rid of other unwanted errors and timestamps. This method is not very good, and the log in Eclipse deletes the old log entries if the list gets too long, meaning I can only look at about 30 seconds of data.
I need much more time than this so I thought of a couple ways to fix the issue:
- If I could somehow write the readings directly from the Android to a document on the computer im using, that would solve all my problems.
- If i could write the readings to a file on the Android that could be saved and later transfered to the computer, that would also work

将文件写入内部 SD 卡非常简单，可能会解决您的第二点。您可以稍后通过 USB 访问该文件，它只是像 USB 拇指驱动器一样安装内部 SD 卡。
例如，此问题和答案为您提供了一些起点。
Writing a file to the internal SD card is quite easy and would probably solve your second point. You can access the file later via USB, which just mounts the internal SD card like an USB thumb drive.
For example, this question and answer gives you some starting points.
