目標是指使用者在 Google Fit 應用程式中自行設定的目標。有助於使用者每天保持活躍。使用者可以在設定檔中調整每天要達成的步數和心肺強化分數。Fit 平台會記錄目標,並追蹤每日活動情況。
透過目標打造更優質的使用者體驗
應用程式可讀取使用者的目標,藉此追蹤個人目標。這有助於打造更吸引人的體驗。首先,請使用
GoalsClient
敬上
讀取使用者的步數和心肺強化分數目標。然後使用
HistoryClient
客戶,就能瞭解他們達成目標的進度。
您可以利用這項資料,協助使用者在 Google Fit 和您的應用程式之間無縫切換,並在兩個應用程式中取得一致的資訊,瞭解使用者達成健身目標的進度。
提供最新資訊和深入分析資料,鼓勵使用者達成每日目標 與遊戲進度有關
讀取目標
下例說明如何建立新的健身客戶,並取得
使用者的心肺強化分數目標,或是null
(如果尚未設定目標)。
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(); }
查看進度
達到使用者的心肺強化分數目標後,您就能使用
HistoryClient
即可查看進度。以下範例說明如何檢查使用者擁有多少心形點數。
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"); } });
以百分比計算進度
如果將檢查進度範例中的總和除以總值 即可依照「閱讀目標」範例中的指定目標,計算出 以及達成目標的進度百分比
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; }
