Sasaran adalah target di aplikasi Google Fit yang dapat ditetapkan pengguna untuk mereka sendiri. Mereka membantu memotivasi pengguna untuk tetap aktif setiap hari. Dari dalam profil, pengguna dapat menyesuaikan jumlah Langkah dan Poin Jantung yang ingin mereka targetkan untuk setiap hari. Platform Fit mencatat sasaran dan melacak aktivitas harian mereka.
Menciptakan pengalaman pengguna yang lebih baik dengan tujuan
Aplikasi Anda dapat membaca sasaran pengguna untuk melacak target pribadinya. Hal ini
dapat membantu menciptakan pengalaman yang lebih menarik. Untuk memulai, gunakan klien
GoalsClient
untuk membaca sasaran Langkah dan Poin Kardio pengguna. Kemudian gunakan klien
HistoryClient
untuk memeriksa seberapa dekat mereka dengan sasaran tersebut.
Gunakan data ini untuk membantu pengguna beralih antara Google Fit dan aplikasi Anda dengan lancar, dan dapatkan informasi yang konsisten di kedua aplikasi tentang progres mereka dalam mencapai target kebugaran.
Motivasi pengguna untuk mencapai sasaran harian mereka dengan memberi mereka info terbaru dan insight terkait progres mereka.
Membaca tujuan
Contoh berikut menunjukkan cara membuat klien Kebugaran baru dan mendapatkan
target Poin Kardio pengguna, atau null jika mereka belum 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:

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:

break;
case UNIT_MONTH:
recurrenceMessage.append("months");
break;
default:
recurrenceMessage.delete(0, recurrenceMessage.length());
recurrenceMessage.append("Unknown");
break;
}
return recurrenceMessage.toString();
}
Periksa progres
Setelah mendapatkan sasaran Poin Kardio pengguna, Anda dapat menggunakan
HistoryClient untuk memeriksa progres mereka. Contoh
berikut 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");
}
});
Hitung kemajuan dalam bentuk persentase
Jika Anda membagi total dari contoh periksa progres dengan target dalam contoh membaca sasaran, Anda dapat menghitung progres menuju sasaran sebagai 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;
}
