C语言 为什么我得到恒定步数在Tizen原生可穿戴设备?

Question

我正在使用Native在Tizen可穿戴设备中运行步数侦听器。我能够访问传感器数据，但它似乎永远打印相同的数据?我做错什么了吗?使用API 3和三星Galaxy Watch 3。

#include "stepcount.h"
#include "sensor.h"
void
example_sensor_callback(sensor_h sensor, sensor_event_s *event, void *user_data)
{
/*
If a callback is used to listen for different sensor types,
it can check the sensor type
*/
sensor_type_e type;
sensor_get_type(sensor, &type);
int i = 0;
if (type == SENSOR_ACCELEROMETER) {
unsigned long long timestamp = event->timestamp;
int accuracy = event->accuracy;
float x = event->values[0];
float y = event->values[1];
float z = event->values[2];
dlog_print(DLOG_INFO, LOG_TAG, "ACCEL: %f %f %f", x,y,z);
} else if (type == SENSOR_HRM) {
unsigned long long timestamp = event->timestamp;
int v = (int)event->values[0];
dlog_print(DLOG_INFO, LOG_TAG, "Heart Rate: %.0f bpm", event->values[0]);
}
else if (type == SENSOR_HUMAN_PEDOMETER ){
unsigned long long timestamp = event->timestamp;
int accuracy = event->accuracy;
int s = (int)event->values[0];
int b = (int)event->values[1];
dlog_print(DLOG_INFO, LOG_TAG, "Step Count: %d", event->values[0]);
dlog_print(DLOG_INFO, LOG_TAG, "Walking Step Count: %d", event->values[1]);
}
}
Base GUI
------
bool supported = false;
sensor_is_supported(SENSOR_HUMAN_PEDOMETER, &supported);
if (!supported) {
/* Accelerometer is not supported on the current device */
}
sensor_h sensor;
sensor_get_default_sensor(SENSOR_HUMAN_PEDOMETER, &sensor);
sensor_listener_h listener;
sensor_create_listener(sensor, &listener);
sensor_listener_start(listener);
/* Register callback */
sensor_listener_set_event_cb(listener, 1000, example_sensor_callback, NULL);
sensor_listener_set_attribute_int(listener, SENSOR_ATTRIBUTE_PAUSE_POLICY, SENSOR_PAUSE_NONE);

这是我的日志

我想正确读取我的实际步数

Answer 1

请按如下更正。

dlog_print(DLOG_INFO, LOG_TAG, "Step Count: %d", s);
dlog_print(DLOG_INFO, LOG_TAG, "Walking Step Count: %d", b);

或

dlog_print(DLOG_INFO, LOG_TAG, "Step Count: %f", event->values[0]);
dlog_print(DLOG_INFO, LOG_TAG, "Walking Step Count: %f", event->values[1]);
