此示例展示了如何创建 Fitness API 客户端。
按如下方式创建 API 客户端:
创建一个
FitnessOptions
实例,声明 应用的数据类型和访问类型(读取和/或写入) 需求:val fitnessOptions = FitnessOptions.builder() .addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ) .addDataType(DataType.AGGREGATE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ) .build()
获取要用于 API 的
Account
对象的实例:val account = GoogleSignIn.getAccountForExtension(this, fitnessOptions)
检查用户之前是否授予了必要的数据访问权限,以及 ,启动授权流程:
if (!GoogleSignIn.hasPermissions(account, fitnessOptions)) { GoogleSignIn.requestPermissions( this, // your activity GOOGLE_FIT_PERMISSIONS_REQUEST_CODE, // e.g. 1 account, fitnessOptions) } else { accessGoogleFit() }
如果需要授权流程,请处理用户的响应:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data) when (resultCode) { Activity.RESULT_OK -> when (requestCode) { GOOGLE_FIT_PERMISSIONS_REQUEST_CODE -> accessGoogleFit() else -> { // Result wasn't from Google Fit } } else -> { // Permission not granted } } }
在用户授权访问所请求数据后,创建健身项目 客户端(例如,用于读取和/或写入历史健身数据的
HistoryClient
) 数据):private fun accessGoogleFit() { val end = LocalDateTime.now() val start = end.minusYears(1) val endSeconds = end.atZone(ZoneId.systemDefault()).toEpochSecond() val startSeconds = start.atZone(ZoneId.systemDefault()).toEpochSecond() val readRequest = DataReadRequest.Builder() .aggregate(DataType.AGGREGATE_STEP_COUNT_DELTA) .setTimeRange(startSeconds, endSeconds, TimeUnit.SECONDS) .bucketByTime(1, TimeUnit.DAYS) .build() val account = GoogleSignIn.getAccountForExtension(this, fitnessOptions) Fitness.getHistoryClient(this, account) .readData(readRequest) .addOnSuccessListener({ response -> // Use response data here Log.i(TAG, "OnSuccess()") }) .addOnFailureListener({ e -> Log.d(TAG, "OnFailure()", e) }) }
