qt 讀取手機傳感器

手機界面對qt 裏面的ui界面支持很低，如果想做個好看的界面還是用qml去搞吧。通過assitant的查找，發現手機有如下傳感器可以使用：

這裏我就挑幾個來說，其他的都類似。下面是QAccelerometer 和 Gyroscope ,代碼如下：

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    setAttribute(Qt::AA_SynthesizeTouchForUnhandledMouseEvents);
    setAttribute(Qt::WA_AcceptTouchEvents);
    ui->setupUi(this);
    gyroscope = new QGyroscope(this);
    gyroscope->start();
    reader = gyroscope->reading();
    acceler = new QAccelerometer(this);
    acceler->setAccelerationMode(QAccelerometer::Combined);
    acceler->start();
    accelereader = acceler->reading();
    qreal x = reader->x();
    qreal y = reader->y();
    qreal z = reader->z();
    ui->lcdNumber->display(x);
    ui->lcdNumber->display(y);
    ui->lcdNumber->display(z);
    x = accelereader->x();
    y = accelereader->y();
    z = accelereader->z();
    ui->lcdNumber_4->display(x);
    ui->lcdNumber_5->display(y);
    ui->lcdNumber_6->display(z);
    timer = new QTimer();
    timer->setInterval(1000);
    connect(timer,SIGNAL(timeout()),this,SLOT(on_pushButton_clicked()));
    timer->start();
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()
{
        qreal x = reader->x();
        qreal y = reader->y();
        qreal z = reader->z();
        ui->lcdNumber->display(x);
        ui->lcdNumber_2->display(y);
        ui->lcdNumber_3->display(z);
        x = accelereader->x();
        y = accelereader->y();
        z = accelereader->z();
        ui->lcdNumber_4->display(x);
        ui->lcdNumber_5->display(y);
        ui->lcdNumber_6->display(z);
}
