我有更多的水平列表視圖。例如,讓我們拿兩個。每個列表的項目長度不一樣,當一個列表滾動時 - 另一個列表也會滾動。我用contentX屬性解決了這個問題。但是,當我想在彼此之間導航時(當我按下「向下」鍵時,我需要強制關注第二個listview)。問題是,重點是記住horizontalna2.currentIndex,我想在ListView中第一個可見的項目。水平列表視圖導航 - 可見項目
在Android中是非常簡單的,但是要在這裏解決,呵呵.. 下面是代碼的草圖:
Rectangle {
width: 500
height: 200
ListModel {
id: model1
ListElement { itemwidth: 100 }
ListElement { itemwidth: 200 }
ListElement { itemwidth: 50 }
ListElement { itemwidth: 70 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
}
ListModel {
id: model2
ListElement { itemwidth: 300 }
ListElement { itemwidth: 50 }
ListElement { itemwidth: 70 }
ListElement { itemwidth: 100 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 30 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
ListElement { itemwidth: 90 }
}
ListView {
clip: true
id: horizontalna
boundsBehavior: Flickable.StopAtBounds
width: 500
height: 60;
focus: true
model: model1
orientation: ListView.Horizontal
KeyNavigation.down: horizontalna2
onContentXChanged: {
if (horizontalna.activeFocus === true)
{
horizontalna2.contentX = horizontalna.contentX
}
}
delegate: Item {
id: containerHorizontal
width: itemwidth; height: 60;
Rectangle {
id: contentHorizontal
anchors.centerIn: parent; width: containerHorizontal.width; height: containerHorizontal.height - 10
color: "transparent"
antialiasing: true
Rectangle { id: insideConHorizontal; anchors.fill: parent; anchors.margins: 3; color: "grey"; antialiasing: true; radius: 5
Text {
id: labelHorizontal
text: "name"
color: "white"
}
}
}
states: State {
name: "active"; when: containerHorizontal.activeFocus
PropertyChanges { target: contentHorizontal; color: "#FFFF00"; scale: 1}
PropertyChanges { target: insideConHorizontal; color: "#F98F06" }
PropertyChanges { target: labelHorizontal; color: "#0E2687"}
}
}
}
ListView {
id: horizontalna2
anchors.top: horizontalna.bottom
boundsBehavior: Flickable.StopAtBounds
width: 500
height: 60;
focus: true
model: model2
orientation: ListView.Horizontal
onContentXChanged: {
if (horizontalna2.activeFocus === true)
{
horizontalna.contentX = horizontalna2.contentX
}
}
delegate: Item {
id: containerHorizontal2
width: itemwidth; height: 60;
Rectangle {
id: contentHorizontal2
anchors.centerIn: parent; width: containerHorizontal2.width; height: containerHorizontal2.height - 10
color: "transparent"
antialiasing: true
Rectangle { id: insideConHorizontal2; anchors.fill: parent; anchors.margins: 3; color: "grey"; antialiasing: true; radius: 5
Text {
id:labelHorizontal2
color: "white"
text: "name"
}
}
}
states: State {
name: "active"; when: containerHorizontal2.activeFocus
PropertyChanges { target: contentHorizontal2; color: "#FFFF00"; scale: 1}
PropertyChanges { target: insideConHorizontal2; color: "#F98F06" }
PropertyChanges { target: labelHorizontal2; color: "#0E2687"}
}
}
}
}
EDIT [解決]: 獲取指數第二個列表的第一個可見項取決於contentX - > function indexAt()
onCurrentIndexChanged: {
if (horizontalna.activeFocus === true)
{
horizontalna2.currentIndex = horizontalna2.indexAt((horizontalna2.contentX),0)
}
}
