Question

Qt对我来说是新的。我按照他们的示例Camera Example和QML Camera Example来构建我自己的应用程序。我使用纯C ++语言而不是QML。该应用程序能够在桌面版本的屏幕上显示取景器，但在Android中无法显示。一切（OSX，NDK，Android SDK，QT）都是最新版本

widget.h

#ifndef WIDGET_H
#define WIDGET_H

#include <QVideoWidget>
#include <QCamera>
#include <QCameraViewfinder>

namespace Ui {
  class Widget;
}

class Widget : public QVideoWidget
{
    Q_OBJECT

  public:
    explicit Widget(QWidget *parent = 0);
    ~Widget();

  private:
    Ui::Widget *ui;
    QCamera *camera;
};

#endif // WIDGET_H

widget.cpp

#include "widget.h"
#include "ui_widget.h"

Widget::Widget(QWidget *parent) :
  QVideoWidget(parent),
  ui(new Ui::Widget)
{
  ui->setupUi(this);

  camera = new QCamera(this);
  camera->setCaptureMode(QCamera::CaptureStillImage);
  camera->setViewfinder(this);
  camera->start();
}

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