Question

我正在尝试以黑莓10本机获取硬件设备的默认信息，所以基本上我正在尝试访问设备的 IMEI 或序列号。

我使用以下代码

的main.cpp

#include "applicationui.hpp"

#include <bb/cascades/Application>
#include <bb/device/HardwareInfo>

#include <QLocale>
#include <QTranslator>

#include <Qt/qdeclarativedebug.h>

using namespace bb::cascades;

Q_DECL_EXPORT int main(int argc, char **argv)
{
    qmlRegisterUncreatableType<bb::device::HardwareInfo>("bb.device", 1, 0, "HardwareInfo", "");
    Application app(argc, argv);
    ApplicationUI appui;
    return Application::exec();
}

applicationui.cpp

#include "applicationui.hpp"

#include <bb/cascades/Application>
#include <bb/cascades/QmlDocument>
#include <bb/cascades/AbstractPane>
#include <bb/device/HardwareInfo>
#include <bb/cascades/Label>

using namespace bb::cascades;
using namespace bb::device;

ApplicationUI::ApplicationUI() :
        QObject()
{
    HardwareInfo hwInfo;
    QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);
    qml->setContextProperty("_hardware", &hwInfo);
    AbstractPane *root = qml->createRootObject<AbstractPane>();
    Application::instance()->setScene(root);
}

main.qml

Page {
    Container {
        Label {
            id: showIMEI
        }
        Button {
            text: "Click me"
            onClicked: {
                showIMEI.text = "IMEI = " + _hardware.serialNumber;
                //showIMEI.text = "IMEI = " + _hardware.imei;
            }
        }
    }
}

但是当我点击一个按钮时，我没有得到任何数据 IMEI 或 SerialNumber 而不是 imei 或序列号< / strong>即可。但总是我得到像

这样的错误
'_hardware' [undefined] is not an object.

注意：我已在 .PRO
中添加了以下库
LIBS += -lbbsystem LIBS += -lbbdevice LIBS += -lbbdata

以及对 XML 文件的权限。

read_device_identifying_information

我还通过许多链接进行了研究，

Link1，Link2，Link3我也阅读了Blackberry的官方文件，但我没有得到正确的方法来完成我的任务。

试试这个，的的main.cpp

#include "applicationui.hpp" #include <bb/cascades/Application> #include <bb/device/HardwareInfo.hpp> #include <QLocale> #include <QTranslator> #include <Qt/qdeclarativedebug.h> using namespace bb::cascades; using namespace bb::device; Q_DECL_EXPORT int main(int argc, char **argv) { qmlRegisterType<HardwareInfo>("bb.device",1,0,"HardwareInfo"); Application app(argc, argv); // Create the Application UI object, this is where the main.qml file // is loaded and the application scene is set. ApplicationUI appui; // Enter the application main event loop. return Application::exec(); }

<强> main.qml

import bb.cascades 1.0 import bb.device 1.0 Page { Container { Label { id: label // Localized text with the dynamic translation and locale updates support text: qsTr("Hello World") + Retranslate.onLocaleOrLanguageChanged textStyle.base: SystemDefaults.TextStyles.BigText multiline: true } Button { onClicked: { label.text=hardwareinfo.imei console.debug("imei\t"+hardwareinfo.imei) console.debug("serialNumber \t"+hardwareinfo.serialNumber) } } } attachedObjects:[ HardwareInfo { id: hardwareinfo } ] }
