Qt / QML SwipeDelegate在移动设备（Android，iOS）上无法正常工作

Question

我是Qt / QML编程的新手，我试图让以下示例在移动设备上正常运行。当我试图＆＃34;向右滑动＆＃34;然后点击删除按钮，＆＃34; Listview-item＆＃34;不会被删除。在桌面上一切正常，但在移动设备上它无法正常工作。任何人都可以帮我解决我的问题吗？

ApplicationWindow {
    id: appWindow
    visible: true

    ListView {
        id: listView
        anchors.fill: parent
        model: ListModel {
            ListElement { name: "Swipe Delegate - Test 1" }
            ListElement { name: "Swipe Delegate - Test 2" }
            ListElement { name: "Swipe Delegate - Test 3" }
            ListElement { name: "Swipe Delegate - Test 4" }

            id: swipeDelegate

                    property: "ListView.delayRemove"

                    easing.type: Easing.InOutQuad
                }
                PropertyAction {
                    target: swipeDelegate;
                    property: "ListView.delayRemove";
                    value: false
                }
            }

            swipe.right: Label {
                id: deleteLabel
                text: qsTr("Delete")
                color: "white"
                verticalAlignment: Label.AlignVCenter
                padding: 12
                height: parent.height
                anchors.right: parent.right

                SwipeDelegate.onClicked: listView.model.remove(index)

                background: Rectangle {
                    color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
                }
            }
        }
    }
}

您可以在Rectangle内添加带有onClicked事件的MouseArea。这是一个例子：

 background: Rectangle {
                color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
                MouseArea {
                    anchors.fill: parent
                    onClicked: listView.model.remove(index)
                }
}
