QT += core gui sensors positioning

其中sensors是获取手机上传感器数据的组件，positioning是获取位置信息的组件

1、获取陀螺仪传感器数据

#include QGyroscope *gyroscope;

QGyroscopeReading *reader;

gyroscope = new QGyroscope(this);

gyroscope->start();

reader = gyroscope->reading();

qreal x = reader->x();

qreal y = reader->y();

qreal z = reader->z();

2、获取加速度传感器数据

#include QAccelerometer *acceler;

QAccelerometerReading *accelereader;

acceler = new QAccelerometer(this);

acceler->setAccelerationMode(QAccelerometer::Combined);

acceler->start();

accelereader = acceler->reading();

qreal x = accelereader->x();

qreal y = accelereader->y();

qreal z = accelereader->z();

3、获取光线强度传感器数据

#include QLightSensor *lightSensor;

QLightReading *lightReading;

lightSensor = new QLightSensor(this);

lightSensor->start();

lightReading = lightSensor->reading();

qreal lux = lightReading->lux();

4、获取电磁传感器数据

#include QMagnetometer *magnetoMeter;

QMagnetometerReading *magnetometerReading;

magnetoMeter = new QMagnetometer(this);

magnetoMeter->start();

magnetometerReading = magnetoMeter->reading();

x = magnetometerReading->x();

y = magnetometerReading->y();

z = magnetometerReading->z();

5、获取接近传感器数据

#include QProximitySensor *proximitySensor;

QProximityReading *proximityReading;

proximitySensor = new QProximitySensor(this);

proximitySensor->start();

proximityReading = proximitySensor->reading();

if(proximityReading->close())

{

ui->label_30->setText("接近传感器：接近");

}

else

{

ui->label_30->setText("接近传感器：远离");

}

6、旋转传感器数据读取

#include QRotationSensor *rotationSensor;

QRotationReading *rotationReading;

rotationSensor = new QRotationSensor(this);

rotationSensor->start();

rotationReading = rotationSensor->reading();

ui->lcdNumber_11->display(rotationReading->x());

ui->lcdNumber_12->display(rotationReading->y());

ui->lcdNumber_13->display(rotationReading->z());

7、获取手机位置相关信息

#include #include #include double nowGroundSpeed=0.0;

double nowVerticalSpeed=0.0;

double nowMagneticVariation=0.0;

double nowHorizontalAccuracy=0.0;

double nowVerticalAccuracy=0.0;

double nowLongitude=0.0;

double nowLatitude=0.0;

double nowDirection=0.0;

QString nowTimes="";

QGeoPositionInfoSource *source;

source = QGeoPositionInfoSource::createDefaultSource(this);

if (source) {

connect(source, SIGNAL(positionUpdated(const QGeoPositionInfo&)),

this, SLOT(positionUpdated(const QGeoPositionInfo&)));

source->setUpdateInterval(200);//设置刷新时间 单位毫秒

source->startUpdates();//启动设备

}

void MainWindow::positionUpdated(const QGeoPositionInfo &info)

{

nowLongitude = info.coordinate().longitude();//经度

nowLatitude = info.coordinate().latitude();//纬度

nowDirection = info.attribute(QGeoPositionInfo::Direction);

nowGroundSpeed = info.attribute(QGeoPositionInfo::GroundSpeed);

nowVerticalSpeed = info.attribute(QGeoPositionInfo::VerticalSpeed);

nowMagneticVariation = info.attribute(QGeoPositionInfo::MagneticVariation);

nowHorizontalAccuracy = info.attribute(QGeoPositionInfo::HorizontalAccuracy);

nowVerticalAccuracy = info.attribute(QGeoPositionInfo::VerticalAccuracy);

nowTimes = info.timestamp().toString();

ui->label_10->setText(nowTimes);

ui->label_12->setText(QString::number(nowLongitude,10,7));

ui->label_14->setText(QString::number(nowLatitude,10,7));

ui->label_16->setText(QString::number(nowGroundSpeed,10,7));

ui->label_18->setText(QString::number(nowVerticalSpeed,10,7));

ui->label_20->setText(QString::number(nowMagneticVariation,10,7));

ui->label_22->setText(QString::number(nowDirection,10,7));

ui->label_24->setText(QString::number(nowHorizontalAccuracy,10,7)+"

"+QString::number(nowVerticalAccuracy,10,7));

}
