如何使用 Google Fit API 查找适用于 Android 的步骤？
我对此进行了几天的研究。我只需要应用程序中的一个简单的 TextView 区域来显示今天的步骤。我已经设法使用下面的代码进行身份验证。它弹出请求许可，并认为我选择了正确的。
但我不知道如何简单地获取步数信息。我希望这只是几行代码。任何帮助将不胜感激。谢谢
编辑1：我只需要获取步数。我可以想办法稍后展示它。我还有一个祝酒词来帮助我弄清楚发生了什么。
private void buildFitnessClient() {
if (mClient == null) {
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.SENSORS_API)
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// Now you can make calls to the Fitness APIs.
Toast.makeText(getBaseContext(), "Connected!", Toast.LENGTH_LONG).show();
}
@Override
public void onConnectionSuspended(int i) {
// If your connection to the sensor gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost.Cause: Network Lost.");
Toast.makeText(getBaseContext(), "Connection lost.Cause: Network Lost.", Toast.LENGTH_LONG).show();
} else if (i
== GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG,
"Connection lost.Reason: Service Disconnected");
}
}
}
)
.enableAutoManage(this, 0, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(ConnectionResult result) {
Log.i(TAG, "Google Play services connection failed. Cause: " +
result.toString());
Toast.makeText(getBaseContext(), "Google Play services connection failed. Cause: " +
result.toString(), Toast.LENGTH_LONG).show();
}
})
.build();
}
}

查看 Google 的官方文档，了解如何从 Fit 读取数据：
// Setting a start and end date using a range of 1 week before this moment.
Calendar cal = Calendar.getInstance();
Date now = new Date();
cal.setTime(now);
long endTime = cal.getTimeInMillis();
cal.add(Calendar.WEEK_OF_YEAR, -1);
long startTime = cal.getTimeInMillis();
java.text.DateFormat dateFormat = getDateInstance();
Log.i(TAG, "Range Start: " + dateFormat.format(startTime));
Log.i(TAG, "Range End: " + dateFormat.format(endTime));
DataReadRequest readRequest = new DataReadRequest.Builder()
// The data request can specify multiple data types to return, effectively
// combining multiple data queries into one call.
// In this example, it's very unlikely that the request is for several hundred
// datapoints each consisting of a few steps and a timestamp.The more likely
// scenario is wanting to see how many steps were walked per day, for 7 days.
.aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
// Analogous to a "Group By" in SQL, defines how data should be aggregated.
// bucketByTime allows for a time span, whereas bucketBySession would allow
// bucketing by "sessions", which would need to be defined in code.
.bucketByTime(1, TimeUnit.DAYS)
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build();
