主要用到AnimatedImage控件即可

import QtQuick 2.5
import QtQuick.Window 2.2

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit();
        }
    }
    AnimatedImage {
        anchors.fill: parent
        source: "qrc:/braking_animation.gif"
    }
    Text {
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
}
