Menggunakan sasaran kebugaran

Sasaran adalah target dalam Google Fit aplikasi yang dapat ditetapkan sendiri oleh pengguna. Dapat membantu memotivasi pengguna untuk tetap aktif setiap mereka. Dari dalam profil mereka, pengguna dapat menyesuaikan berapa banyak Langkah dan Poin Jantung yang ingin dibidik untuk setiap hari. Platform Fit mencatat sasaran dan melacak aktivitas harian mereka aktivitas terhadapnya.

Menciptakan pengalaman pengguna yang lebih baik dengan tujuan

Aplikasi Anda dapat membaca sasaran pengguna untuk melacak target pribadinya. Ini dapat membantu menciptakan pengalaman yang lebih menarik. Untuk memulai, gunakan GoalsClient klien untuk membaca Langkah dan sasaran Poin Kardio pengguna. Kemudian gunakan HistoryClient klien untuk memeriksa seberapa dekat mereka dengan tujuan tersebut.

Gunakan data ini untuk membantu pengguna beralih antara Google Fit dan aplikasi Anda lancar, dan mendapatkan informasi yang konsisten di kedua aplikasi tentang kemajuan mereka menuju sasaran kebugaran mereka.

Memotivasi pengguna untuk mencapai sasaran harian mereka dengan memberi mereka info terbaru dan insight yang terkait dengan kemajuan mereka.

Membaca sasaran

Contoh berikut menunjukkan cara membuat klien Kebugaran baru dan mendapatkan target Poin Kardio pengguna, atau null jika mereka tidak menetapkan sasaran.

Kotlin

private val fitnessOptions: FitnessOptions by lazy {
    FitnessOptions.builder()
        .addDataType(DataType.TYPE_HEART_POINTS, FitnessOptions.ACCESS_READ)
        .build()
}

private val goalsReadRequest: GoalsReadRequest by lazy {
    GoalsReadRequest.Builder()
        .addDataType(DataType.TYPE_HEART_POINTS)
        .build()
}

private fun getGoogleAccount(): GoogleSignInAccount =
    GoogleSignIn.getAccountForExtension(requireContext(), fitnessOptions)


private fun readGoals() {
    Fitness.getGoalsClient(requireContext(), getGoogleAccount())
        .readCurrentGoals(goalsReadRequest)
        .addOnSuccessListener { goals ->
            // There should be at most one heart points goal currently.
            goals.firstOrNull()?.apply {
                // What is the value of the goal
                val goalValue = metricObjective.value
                Log.i(TAG, "Goal value: $goalValue")

                // How is the goal measured?
                Log.i(TAG, "Objective: $objective")

                // How often does the goal repeat?
                Log.i(TAG, "Recurrence: $recurrenceDetails")
            }
        }
}

private val Goal.objective: String
    get() = when (objectiveType) {
        OBJECTIVE_TYPE_DURATION ->
            "Duration (s): ${durationObjective.getDuration(TimeUnit.SECONDS)}"
        OBJECTIVE_TYPE_FREQUENCY ->
            "Frequency : ${frequencyObjective.frequency}"
        OBJECTIVE_TYPE_METRIC ->
            "Metric : ${metricObjective.dataTypeName} - ${metricObjective.value}"
        else -> "Unknown objective"
    }

private val Goal.recurrenceDetails: String
    get() = recurrence?.let {
        val period = when (it.unit) {
            Recurrence.UNIT_DAY -> "days"
            Recurrence.UNIT_WEEK -> "weeks"
            Recurrence.UNIT_MONTH -> "months"
            else -> "Unknown"
        }
        "Every ${recurrence!!.count} $period"
    } ?: "Does not repeat"

Java

private final FitnessOptions fitnessOptions = FitnessOptions.builder()
            .addDataType(DataType.TYPE_HEART_POINTS, FitnessOptions.ACCESS_READ)
            .build();


private final GoalsReadRequest goalsReadRequest = new GoalsReadRequest.Builder()
            .addDataType(DataType.TYPE_HEART_POINTS)
            .build();

private GoogleSignInAccount getGoogleAccount() {
    GoogleSignIn.getAccountForExtension(getApplicationContext(), fitnessOptions);
}


private void readGoals() {
    Fitness.getGoalsClient(getApplicationContext(), getGoogleAccount())
            .readCurrentGoals(goalsReadRequest)
            .addOnSuccessListener(goals -> {
                // There should be at most one heart points goal currently.
                Optional<Goal> optionalGoal = goals.stream().findFirst();
                if (optionalGoal.isPresent()) {
                    // What is the value of the goal
                    double goalValue = optionalGoal.get().getMetricObjective().getValue();
                    Log.i(TAG, "Goal value: $goalValue");

                    // How is the goal measured?
                    Log.i(TAG, "Objective: ${getObjective(optionalGoal.get())}");

                    // How often does the goal repeat?
                    Log.i(TAG, "Recurrence: ${getRecurrenceDetails(optionalGoal.get())}");
                }

    });
}

private String getObjective(Goal goal) {
    switch (goal.getObjectiveType()) {
        case OBJECTIVE_TYPE_DURATION:
            return "Duration (s): ${goal.getDurationObjective().getDuration(TimeUnit.SECONDS)}";
        case OBJECTIVE_TYPE_FREQUENCY:
            return "Frequency : ${goal.getFrequencyObjective().getFrequency()}";
        case OBJECTIVE_TYPE_METRIC:
            return "Metric : ${goal.getMetricObjective().getDataTypeName()} - ${goal.getMetricObjective().getValue()}";
        default:
            return "Unknown objective";
    }
}

private String getRecurrenceDetails(Goal goal) {
    Goal.Recurrence recurrence = goal.getRecurrence();
    if (recurrence == null) {
        return "Does not repeat";
    }

    StringBuilder recurrenceMessage = new StringBuilder("Every ${recurrence.getCount()}");

    switch (recurrence.getUnit()) {
        case UNIT_DAY:
            recurrenceMessage.append("days");
            break;
        case UNIT_WEEK:
            recurrenceMessage.append("weeks");
            break;
        case UNIT_MONTH:
            recurrenceMessage.append("months");
            break;
        default:
            recurrenceMessage.delete(0, recurrenceMessage.length());
            recurrenceMessage.append("Unknown");
            break;
    }

    return recurrenceMessage.toString();
}

Periksa progres

Setelah Anda memiliki sasaran Poin Kardio pengguna, Anda dapat menggunakan HistoryClient untuk memeriksa progresnya. Hal berikut contoh menunjukkan cara memeriksa jumlah Poin Kardio yang dimiliki pengguna.

Kotlin

val current = Calendar.getInstance()
val request = DataReadRequest.Builder()
    .read(DataType.TYPE_HEART_POINTS)
    .setTimeRange(
        goal.getStartTime(current, TimeUnit.NANOSECONDS),
        goal.getEndTime(current, TimeUnit.NANOSECONDS),
        TimeUnit.NANOSECONDS
    )
    .build()

Fitness.getHistoryClient(requireContext(), getGoogleAccount())
    .readData(request)
    .addOnSuccessListener { response ->
        val heartPointsSet = response.dataSets.first()
        val totalHeartPoints = heartPointsSet.dataPoints.sumBy {
            it.getValue(Field.FIELD_INTENSITY).asFloat().toInt()
        }
        Log.i(TAG, "Total heart points: $totalHeartPoints")
    }

Java

Calendar current = Calendar.getInstance();
DataReadRequest request = new DataReadRequest.Builder()
        .read(DataType.TYPE_HEART_POINTS)
        .setTimeRange(
                goal.getStartTime(current, TimeUnit.NANOSECONDS),
                goal.getEndTime(current, TimeUnit.NANOSECONDS),
                TimeUnit.NANOSECONDS
        )
        .build();


Fitness.getHistoryClient(getApplicationContext(), getGoogleAccount())
        .readData(request)
        .addOnSuccessListener(response -> {
            Optional<DataSet> heartPointsSet = response.getDataSets().stream().findFirst();
            if (heartPointsSet.isPresent()) {
                int totalHeartPoints = 0;
                for (DataPoint dp : heartPointsSet.get().getDataPoints()) {
                    totalHeartPoints += (int) dp.getValue(Field.FIELD_INTENSITY).asFloat();
                }

                Log.i(TAG, "Total heart points: $totalHeartPoints");
            }
        });

Menghitung progres dalam persentase

Jika Anda membagi total dari contoh check progress berdasarkan target dalam contoh baca sasaran, Anda dapat menghitung progres menuju sasaran dalam persentase.

Kotlin

private fun calculateProgressPercentage(goal: Goal, response: DataReadResponse): Double {
    val goalValue = goal.metricObjective.value
    val currentTotal = response.dataSets.first().dataPoints.sumBy {
        it.getValue(Field.FIELD_INTENSITY).asFloat().toInt()
    }

    return (currentTotal.div(goalValue)).times(100.0)
}

Java

private double calculateProgressPercentage(Goal goal, DataReadResponse response) {
    double goalValue = goal.getMetricObjective().getValue();
    Optional<DataSet> firstDataSet = response.getDataSets().stream().findFirst();
    if (!(firstDataSet.isPresent())) {
        return NaN;
    }
    double currentTotal = 0;
    for (DataPoint dp : firstDataSet.get().getDataPoints()) {
        currentTotal += (int)dp.getValue(Field.FIELD_INTENSITY).asFloat();
    }

    return (currentTotal / goalValue) * 100.0;
}
