Xamarin Monodroid:WP7 =>Android 和自定义控件? [英] Xamarin Monodroid: WP7 => Android and Custom Control?

问题描述

我正在使用 Xamarin Monodroid 将我的一些 Windows Phone 应用程序移植到 Android.

i am in the process of porting some of my Windows Phone Applications to Android using Xamarin Monodroid.

我对 Xamarin 的东西很陌生，实际上只是买了一个许可证.

I am pretty new with the Xamarin stuff, just bought a license actually.

就在 AXML 中重新创建 XAML UI 而言，到目前为止一切顺利，但我遇到了自定义控件的问题.

So far so good as far as recreating the XAML UI in AXML but i am facing a problem with Custom Controls.

这就是我所说的自定义控件的意思:

Here is what i mean by custom controls:

在 .NET 中，我通过创建继承自UserControl"类的类创建了一堆控件，我创建了逻辑并设置了内容.然后我只是用'new my_control()'等创建新实例......

In .NET, i created a bunch of controls by creating class that inherit from the 'UserControl' class, i created the logic and set the Content. Then i just create new instance with 'new my_control()', etc...

我的一些控件不是以这种方式创建的，而是通过定义 XAML 创建了 UserControl，其中没有特定的逻辑，但是当我需要组合 2 个或更多控件时(例如，带有文本的彩色方块旁边，所以 Rectangle + TextBlock) 再次我只需要执行new my_control()"并将其添加到 XAML UI(网格、ListBox、StackPanel 等...)中的某处.

Some of my controls are not created this way but instead i created the UserControl by defining the XAML, where there is no specific logics but when i need to combine 2 or more controls(for example, a colored square with text beside it, so Rectangle + TextBlock) and again i just need to do 'new my_control()' and add it somewhere in the XAML UI(Grid, ListBox, StackPanel, etc...).

我如何使用 Monodroid 实现类似的功能?

How can i achieve something similar with Monodroid?

提前致谢！

推荐答案

您也可以在 Mono for Android 中进行自定义控件" - 一旦您编写了它们，就可以将它们包含在您的 axml 文件中.

You can do "custom controls" in Mono for Android too - and once you've written them, then you can include them in your axml files.

恐怕我手头没有任何非常简单的例子，但有一个复杂的例子:

I'm afraid I don't have any perfectly simple examples to hand, but there's a complicated example in:

https://github.com/slodge/MvvmCross/blob/master/Sample%20-%20CirriousConference/Cirrious.Conference.UI.Droid/Resources/Layout/ChildPage_Twitter.axml

如果您在 MyNamespace 中声明一个类 MyControl 并从 Android View 继承该控件，然后您可以设置自定义控件 - 包括从 XML 中提取属性 - 使用如下构造函数:

If you declare a class MyControl in MyNamespace and inherit that control from an Android View and you can then setup your custom control - including pulling in attributes from the XML - using a constructor like:

public MyControl(Context context, IAttributeSet attrs) { /* ... */ }

并使用 XML 如下:

and using XML like:

<mynamespace.MyControl android:layout_height='wrap_content' />

一个例子可能是来自 https://github.com/Cheesebaron/MonoDroid.Horizo​​ntalPager 的控件 - 可以从 xml 使用 xml 使用，如

---

One example of this could be the control from https://github.com/Cheesebaron/MonoDroid.HorizontalPager - which could be used from xml using xml like

 <mynamespace.controls.HorizontalPager
    android:id="@+id/MyPageHost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />
