如何使用Google Fit的API获取用户当前的速度?
作者:互联网
目前使用Google Fit API并且在使用Sensors API时遇到一些问题.我正在尝试获取用户当前的应用程序锻炼速度,但文档有点令人困惑.
在此代码段中是Google信息页面中的示例:
Fitness.SensorsApi.add(
mClient,
new SensorRequest.Builder()
// Optional but recommended for custom data sets.
.setDataType(DataType.TYPE_SPEED)// Can't be omitted.
.setSamplingRate(1, TimeUnit.SECONDS).setAccuracyMode(SensorRequest.ACCURACY_MODE_HIGH)
.build(), mListener3)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "Listener registered!");
} else {
Log.i(TAG, "Listener not registered.");
}
}
});
//添加监听器
mListener3 = new OnDataPointListener() {
@Override
public void onDataPoint(DataPoint dataPoint) {
final float speed = dataPoint.getValue(Field.FIELD_SPEED).asFloat();
runOnUiThread(new Runnable() {
@Override
public void run() {
Log.i(TAG, "In Speed" + speed );
speedTxtView.setText("" + speed );
}
});
}
目前,我正在获取所有其他数据类型值,如距离,心率,步数和当前活动,但无法获得用户当前的速度.
我做得对吗?
解决方法:
您可以尝试使用Google Fit Github存储库中的basichistorysessions sample.
示例代码:
// Build a session read request
SessionReadRequest readRequest = new SessionReadRequest.Builder()
.setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)
.read(DataType.TYPE_SPEED)
.setSessionName(SAMPLE_SESSION_NAME)
.build();
// Invoke the Sessions API to fetch the session with the query and wait for the result
// of the read request.
SessionReadResult sessionReadResult =
Fitness.SessionsApi.readSession(mClient, readRequest)
.await(1, TimeUnit.MINUTES);
// Get a list of the sessions that match the criteria to check the result.
Log.i(TAG, "Session read was successful. Number of returned sessions is: "
+ sessionReadResult.getSessions().size());
for (Session session : sessionReadResult.getSessions()) {
// Process the session
dumpSession(session);
// Process the data sets for this session
List<DataSet> dataSets = sessionReadResult.getDataSet(session);
for (DataSet dataSet : dataSets) {
dumpDataSet(dataSet);
}
}
