我正在創建一個自定義的ViewCell,以便在ListView中使用,就像我以前做過很多次一樣。但是,這是我第一次需要在自定義ViewCell中使用圖像,並且無法使其工作。Xamarin - 在自定義列表視圖中使用圖像ViewCell
所以,我有我的模型:
public class AttendedMeeting
{
public string Title { get; set; }
public string Date { get; set; }
public string Status { get; set; }
public Image MeetingImage { get; set;}
}
而且在我的自定義ViewCell:
Label titleLabel = new Label();
titleLabel.SetBinding(Label.TextProperty, "Title");
Label dateLabel = new Label();
dateLabel.SetBinding(Label.TextProperty, "Date");
Label statusLabel = new Label();
statusLabel.SetBinding(Label.TextProperty, "Status");
Image meetingImage = new Image();
meetingImage.SetBinding(Image.SourceProperty, "MeetingImage");
然後在我的網頁,我填充對象的列表如下:
ListView meetingsListView = new ListView();
Image imageCheck = new Image();
imageCheck.Source = "Check.png";
Image imageLine = new Image();
imageLine.Source = "Line.png";
Image imageCircle = new Image();
imageCircle.Source = "Circle.png";
meetingsListView.ItemsSource = new AttendedMeeting[] {
new AttendedMeeting {Title = "Meeting 1",
Date="Monday - May 16th 2016",
Status="Verified",
MeetingImage=imageCheck
},
new AttendedMeeting {Title = "Meeting 2",
Date="Monday - May 16th 2016",
Status="Verified",
MeetingImage=imageLine
},
new AttendedMeeting {Title = "Meeting 3",
Date="Monday - May 16th 2016",
Status="Verified",
MeetingImage=imageCheck
},
new AttendedMeeting {Title = "Meeting 4",
Date="Monday - May 16th 2016",
Status="Verified",
MeetingImage=imageCheck
}
};
meetingsListView.ItemTemplate = new DataTemplate(typeof(CellMeetingsAttended));
除了圖像以外,一切都很棒。標籤填充得很好,但每個項目上的圖像總是空白。誰能告訴我我做錯了什麼?我也嘗試在模型中使用字符串而不是Image(),並使用字符串設置圖像源,並且也沒有運氣。我已驗證資源是否正確,我可以將它們顯示爲ListView外部的圖像。
在此先感謝。
非常感謝。這工作加上它也導致我另一個領域,我沒有正確設置來源,工程太棒了! – AS2012
