我已经OxyPlot在使用XamarinPCL的项目中添加了Android和Core MVVMCross。
我已经在我的xml中添加了plotview，如下所示。但是我不知道如何使用MVVMCross绑定此视图。
有什么好的榜样或资源可循吗？
MyView.xml
<oxyplot.xamarin.android.PlotView
android:id="@+id/plot"
android:layout_width="match_parent"
android:layout_height="match_parent" />
MyView.cs
public class MyView : MvxFragment<MyViewModel>
{
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var ignored = base.OnCreateView(inflater, container, savedInstanceState);
var view = this.BindingInflate(Resource.Layout.MyView, null)
MyViewModel MyMainViewModel = new MyViewModel();
var a = view.FindViewById<PlotView>(Resource.Id.plot);
a.Model = MyViewModel.MyModel;
return view;
}
}
MyViewModel.cs
public PlotModel MyModel { get; set; }
public MyViewModel
{
PlotModel mo = new PlotModel();
var s1 = new LineSeries()
{
Color = OxyColors.SkyBlue,
MarkerType = MarkerType.Circle,
MarkerSize = 6,
MarkerStroke = OxyColors.White,
MarkerFill = OxyColors.SkyBlue,
MarkerStrokeThickness = 1.5
};
s1.Points.Add(new DataPoint(0, 10));
s1.Points.Add(new DataPoint(10, 40));
s1.Points.Add(new DataPoint(40, 20));
s1.Points.Add(new DataPoint(60, 30));
mo.Series.Add(s1);
MyModel = mo;
}
OxyPlot安装的附加信息
我已经通过Package Console添加了OxyPlot，如下所示。
在PCL中
PM> Install-Package OxyPlot.Core -Version 1.0.0-unstable1983 -Pre
在Android中
PM> Install-Package OxyPlot.Xamarin.Android -Pre
或者，您也可以从prelease库在Nuget控制台中添加它们。
您应该能够使用标准Mvx属性绑定来实现所需的功能。无需自定义绑定。
基于问题的示例：
方法1：流利的绑定
视图模型
public class MyViewModel : MvxViewModel
{
public MyViewModel()
{
GeneratePlotPoints();
}
void GeneratePlotPoints()
{
var mo = new PlotModel();
var s1 = new LineSeries()
{
Color = OxyColors.SkyBlue,
MarkerType = MarkerType.Circle,
MarkerSize = 6,
MarkerStroke = OxyColors.White,
MarkerFill = OxyColors.SkyBlue,
MarkerStrokeThickness = 1.5
};
s1.Points.Add(new DataPoint(0, 10));
s1.Points.Add(new DataPoint(10, 40));
s1.Points.Add(new DataPoint(40, 20));
s1.Points.Add(new DataPoint(60, 30));
mo.Series.Add(s1);
MyModel = mo;
}
PlotModel _myModel;
public PlotModel MyModel
{
get { return _myModel; }
set { SetProperty(ref _myModel, value); }
}
}
查看/布局
<oxyplot.xamarin.android.PlotView
android:id="@+id/plot"
android:layout_width="match_parent"
android:layout_height="match_parent" />
片段/代码后面
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var ignored = base.OnCreateView(inflater, container, savedInstanceState);
var view = this.BindingInflate(Resource.Layout.MyView, null);
var graphControl = view.FindViewById<PlotView>(Resource.Id.plot);
var bindset = this.CreateBindingSet<MyView, MyViewModel>();
bindset.Bind(graphControl).For(c => c.Model).To(vm => vm.MyModel);
bindset.Apply();
return view;
}
方法2：Xml绑定
视图模型
同上
查看/布局
<oxyplot.xamarin.android.PlotView
android:id="@+id/plot"
android:layout_width="match_parent"
android:layout_height="match_parent"
local:MvxBind="Model MyModel"/>
片段/代码后面
无需绑定代码，只需确保通过绑定充气机运行布局即可。
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var ignored = base.OnCreateView(inflater, container, savedInstanceState);
return this.BindingInflate(Resource.Layout.MyView, null);
}
