QML ListView常用且重要的属性

将切换模式设置为单张切换:snapMode: ListView.SnapOneItem
将列表改成水平浏览模式:orientation:ListView.Horizontal
currentIndex跟随变化:highlightRangeMode: ListView.StrictlyEnforceRange
禁止首尾滑动: boundsBehavior:Flickable.StopAtBounds
设置最大滑动速度:maximumFlickVelocity:7000       //像素/秒

添加header或footer:

ListView{
        id:listView
        anchors.fill: parent
        model: 10
        headerPositioning: ListView.PullBackHeader

        header: Rectangle{
            width: listView.width
            height: 70
            color: "green"
            Label{
                anchors.centerIn: parent
                text: "this is header"
            }
        }

        onCurrentIndexChanged: {
            console.log("current index = ",currentIndex)
        }

        delegate: Rectangle{
              width: listView.width
              height: 280
              color: index%2 ? "red":"yellow"
              Label{
                  id:txt
                  anchors.centerIn: parent
                  font.pointSize: 100
                  text: index
              }
              Label{
                  anchors.top: txt.bottom
                  font.pointSize: 30
                  text: "currentIndex = " + listView.currentIndex
                  anchors.horizontalCenter: parent.horizontalCenter
              }
        }
    }

下拉刷新:

import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Controls 2.2

Window {
    visible: true
    width: 250
    height: 350
    title: qsTr("ListView")
    property bool refreshFlag: false

    Rectangle{
        width: parent.width
        height: -listView.contentY
        color: "cyan"
        Label{
            anchors.centerIn: parent
            text:"下拉刷新"
            visible: listView.contentYr
        }
    }

    BusyIndicator{
        id:busy
        z:4
        running: false
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.top: parent.top
        anchors.topMargin: parent.height/3.
        Timer{
            interval: 2000
            running: busy.running
            onTriggered: {
                busy.running = false
            }
        }
    }

    ListView{
        id:listView
        anchors.fill: parent
        model: 30

        onContentYChanged: {
            if(-contentY > 40){
                refreshFlag = true
            }
        }
        onMovementEnded: {
            if(refreshFlag){
                refreshFlag = false
                busy.running = true
            }
        }

        onCurrentIndexChanged: {
            console.log("current index = ",currentIndex)
        }

        delegate: Rectangle{
              width: listView.width
              height: 70
              color: index%2 ? "red":"yellow"
              Label{
                  id:txt
                  anchors.centerIn: parent
                  font.pointSize: 20
                  text: index
              }
        }
    }
}
