Gli obiettivi sono target in Google Fit
app
che gli utenti possono impostare autonomamente. Contribuiscono a motivare gli utenti a rimanere attivi ogni
giorno. Dal proprio profilo, gli utenti possono modificare il numero di
Punti cardio a cui vogliono mirare
per ogni giorno. La piattaforma Fit registra gli obiettivi e monitora gli obiettivi giornalieri
attività rispetto a questi elementi.
Creare un'esperienza utente migliore con gli obiettivi
La tua app può leggere gli obiettivi di un utente per monitorare i suoi obiettivi personali. Questo
possono contribuire a creare
un'esperienza più coinvolgente. Per iniziare, utilizza la
GoalsClient
di leggere gli obiettivi Passi e Punti cardio dell'utente. Quindi utilizza
HistoryClient
cliente per verificare quanto sia vicino a questi obiettivi.
Utilizza questi dati per aiutare gli utenti a passare da Google Fit alla tua app
senza problemi e di avere informazioni coerenti sui loro progressi in entrambe le app
per raggiungere i suoi obiettivi di fitness.
Motiva gli utenti a raggiungere i loro obiettivi quotidiani fornendo loro aggiornamenti e approfondimenti
in relazione ai loro progressi.
Leggere un obiettivo
L'esempio seguente mostra come creare un nuovo client per il fitness e ottenere il
obiettivo Punti cardio dell'utente o null se non ne ha impostato uno.

They help motivate users to stay active every\nday. From within their profile, users can adjust how many Steps and\n[Heart Points](https://support.google.com/fit/answer/7619539) they want to aim\nfor each day. The Fit platform records their goals and tracks their daily\nactivity against these.\n\nCreate a better user experience with goals\n------------------------------------------\n\nYour app can read a user's goals to keep track of their personal targets. This\ncan help create a more engaging experience. To start, use the\n[`GoalsClient`](/android/reference/com/google/android/gms/fitness/GoalsClient)\nclient to read a user's Steps and Heart Points goals. Then use the\n[`HistoryClient`](/android/reference/com/google/android/gms/fitness/HistoryClient)\nclient to check how close they are to those goals.\n\nUse this data to help users switch between Google Fit and your app\nseamlessly, and get consistent information across both apps about their progress\ntowards their fitness goals.\n\nMotivate users to reach their daily goals by giving them updates and insights\nrelated to their progress.\n\nRead a goal\n-----------\n\nThe following example shows how to create a new Fitness client and get the\nuser's Heart Points goal, or `null` if they don't have a goal set. \n\n### Kotlin\n\n```kotlin\nprivate val fitnessOptions: FitnessOptions by lazy {\n FitnessOptions.builder()\n .addDataType(DataType.TYPE_HEART_POINTS, FitnessOptions.ACCESS_READ)\n .build()\n}\n\nprivate val goalsReadRequest: GoalsReadRequest by lazy {\n GoalsReadRequest.Builder()\n .addDataType(DataType.TYPE_HEART_POINTS)\n .build()\n}\n\nprivate fun getGoogleAccount(): GoogleSignInAccount =\n GoogleSignIn.getAccountForExtension(requireContext(), fitnessOptions)\n\n\nprivate fun readGoals() {\n Fitness.getGoalsClient(requireContext(), getGoogleAccount())\n .readCurrentGoals(goalsReadRequest)\n .addOnSuccessListener { goals -\u003e\n // There should be at most one heart points goal currently.\n goals.firstOrNull()?.apply {\n // What is the value of the goal\n val goalValue = metricObjective.value\n Log.i(TAG, \"Goal value: $goalValue\")\n\n // How is the goal measured?\n Log.i(TAG, \"Objective: $objective\")\n\n // How often does the goal repeat?\n Log.i(TAG, \"Recurrence: $recurrenceDetails\")\n }\n }\n}\n\nprivate val Goal.objective: String\n get() = when (objectiveType) {\n OBJECTIVE_TYPE_DURATION -\u003e\n \"Duration (s): ${durationObjective.getDuration(TimeUnit.SECONDS)}\"\n OBJECTIVE_TYPE_FREQUENCY -\u003e\n \"Frequency : ${frequencyObjective.frequency}\"\n OBJECTIVE_TYPE_METRIC -\u003e\n \"Metric : ${metricObjective.dataTypeName} - ${metricObjective.value}\"\n else -\u003e \"Unknown objective\"\n }\n\nprivate val Goal.recurrenceDetails: String\n get() = recurrence?.let {\n val period = when (it.unit) {\n Recurrence.UNIT_DAY -\u003e \"days\"\n Recurrence.UNIT_WEEK -\u003e \"weeks\"\n Recurrence.UNIT_MONTH -\u003e \"months\"\n else -\u003e \"Unknown\"\n }\n \"Every ${recurrence!!.count} $period\"\n } ?: \"Does not repeat\"\n```\n\n### Java\n\n```java\nprivate final FitnessOptions fitnessOptions = FitnessOptions.builder()\n .addDataType(DataType.TYPE_HEART_POINTS, FitnessOptions.ACCESS_READ)\n .build();\n\n\nprivate final GoalsReadRequest goalsReadRequest = new GoalsReadRequest.Builder()\n .addDataType(DataType.TYPE_HEART_POINTS)\n .build();\n\nprivate GoogleSignInAccount getGoogleAccount() {\n GoogleSignIn.getAccountForExtension(getApplicationContext(), fitnessOptions);\n}\n\n\nprivate void readGoals() {\n Fitness.getGoalsClient(getApplicationContext(), getGoogleAccount())\n .readCurrentGoals(goalsReadRequest)\n .addOnSuccessListener(goals -\u003e {\n // There should be at most one heart points goal currently.\n Optional\u003cGoal\u003e optionalGoal = goals.stream().findFirst();\n if (optionalGoal.isPresent()) {\n // What is the value of the goal\n double goalValue = optionalGoal.get().getMetricObjective().getValue();\n Log.i(TAG, \"Goal value: $goalValue\");\n\n // How is the goal measured?\n Log.i(TAG, \"Objective: ${getObjective(optionalGoal.get())}\");\n\n // How often does the goal repeat?\n Log.i(TAG, \"Recurrence: ${getRecurrenceDetails(optionalGoal.get())}\");\n }\n\n });\n}\n\nprivate String getObjective(Goal goal) {\n switch (goal.getObjectiveType()) {\n case OBJECTIVE_TYPE_DURATION:\n return \"Duration (s): ${goal.getDurationObjective().getDuration(TimeUnit.SECONDS)}\";\n case OBJECTIVE_TYPE_FREQUENCY:\n return \"Frequency : ${goal.getFrequencyObjective().getFrequency()}\";\n case OBJECTIVE_TYPE_METRIC:\n return \"Metric : ${goal.getMetricObjective().getDataTypeName()} - ${goal.getMetricObjective().getValue()}\";\n default:\n return \"Unknown objective\";\n }\n}\n\nprivate String getRecurrenceDetails(Goal goal) {\n Goal.Recurrence recurrence = goal.getRecurrence();\n if (recurrence == null) {\n return \"Does not repeat\";\n }\n\n StringBuilder recurrenceMessage = new StringBuilder(\"Every ${recurrence.getCount()}\");\n\n switch (recurrence.getUnit()) {\n case UNIT_DAY:\n recurrenceMessage.append(\"days\");\n break;\n case UNIT_WEEK:\n recurrenceMessage.append(\"weeks\");\n break;\n case UNIT_MONTH:\n recurrenceMessage.append(\"months\");\n break;\n default:\n recurrenceMessage.delete(0, recurrenceMessage.length());\n recurrenceMessage.append(\"Unknown\");\n break;\n }\n\n return recurrenceMessage.toString();\n}\n```\n\nCheck progress\n--------------\n\nAfter you have the user's Heart Points goal, you can use the\n[`HistoryClient`](/fit/android/history) to check their progress. The following\nexample shows how to check how many Heart Points the user has.\n**Note:** The time range for a goal is calculated based on its frequency. For example, for a daily goal, the current time is used to calculate when the day starts and ends. Where the goal is a daily goal, the code can be simplified by using [`HistoryClient.readDailyTotal()`](/android/reference/com/google/android/gms/fitness/HistoryClient#public-taskdataset-readdailytotal-datatype-datatype) instead of [`HistoryClient.readData()`](/android/reference/com/google/android/gms/fitness/HistoryClient#public-taskdatareadresponse-readdata-datareadrequest-request). This example only uses `HistoryClient.readData()` to show how Goal objects can be used to identify the start and end times of the current recurrence when you query for progress. \n\n### Kotlin\n\n```kotlin\nval current = Calendar.getInstance()\nval request = DataReadRequest.Builder()\n .read(DataType.TYPE_HEART_POINTS)\n .setTimeRange(\n goal.getStartTime(current, TimeUnit.NANOSECONDS),\n goal.getEndTime(current, TimeUnit.NANOSECONDS),\n TimeUnit.NANOSECONDS\n )\n .build()\n\nFitness.getHistoryClient(requireContext(), getGoogleAccount())\n .readData(request)\n .addOnSuccessListener { response -\u003e\n val heartPointsSet = response.dataSets.first()\n val totalHeartPoints = heartPointsSet.dataPoints.sumBy {\n it.getValue(Field.FIELD_INTENSITY).asFloat().toInt()\n }\n Log.i(TAG, \"Total heart points: $totalHeartPoints\")\n }\n```\n\n### Java\n\n```java\nCalendar current = Calendar.getInstance();\nDataReadRequest request = new DataReadRequest.Builder()\n .read(DataType.TYPE_HEART_POINTS)\n .setTimeRange(\n goal.getStartTime(current, TimeUnit.NANOSECONDS),\n goal.getEndTime(current, TimeUnit.NANOSECONDS),\n TimeUnit.NANOSECONDS\n )\n .build();\n\n\nFitness.getHistoryClient(getApplicationContext(), getGoogleAccount())\n .readData(request)\n .addOnSuccessListener(response -\u003e {\n Optional\u003cDataSet\u003e heartPointsSet = response.getDataSets().stream().findFirst();\n if (heartPointsSet.isPresent()) {\n int totalHeartPoints = 0;\n for (DataPoint dp : heartPointsSet.get().getDataPoints()) {\n totalHeartPoints += (int) dp.getValue(Field.FIELD_INTENSITY).asFloat();\n }\n\n Log.i(TAG, \"Total heart points: $totalHeartPoints\");\n }\n });\n```\n\nCalculate progress as a percentage\n----------------------------------\n\nIf you divide the total from the [check progress](#check-progress) example\nby the target in the [read a goal](#read-a-goal) example, you can calculate the\nprogress towards the goal as a percentage. \n\n### Kotlin\n\n```kotlin\nprivate fun calculateProgressPercentage(goal: Goal, response: DataReadResponse): Double {\n val goalValue = goal.metricObjective.value\n val currentTotal = response.dataSets.first().dataPoints.sumBy {\n it.getValue(Field.FIELD_INTENSITY).asFloat().toInt()\n }\n\n return (currentTotal.div(goalValue)).times(100.0)\n}\n```\n\n### Java\n\n```java\nprivate double calculateProgressPercentage(Goal goal, DataReadResponse response) {\n double goalValue = goal.getMetricObjective().getValue();\n Optional\u003cDataSet\u003e firstDataSet = response.getDataSets().stream().findFirst();\n if (!(firstDataSet.isPresent())) {\n return NaN;\n }\n double currentTotal = 0;\n for (DataPoint dp : firstDataSet.get().getDataPoints()) {\n currentTotal += (int)dp.getValue(Field.FIELD_INTENSITY).asFloat();\n }\n\n return (currentTotal / goalValue) * 100.0;\n}\n```"]]
