在Android中检索视图的XML属性

I'd like to implement a custom Preference with an icon and be able to define the source of the icon in the XML specification of the view. If I do

我想用图标实现自定义首选项，并能够在视图的XML规范中定义图标的来源。如果我做

<com.example.MyIconPreference
    android:src="@drawable/icon1"
    android:key="test_key"
    android:title="@string/pref_title"
    android:summary="@string/pref_summary"
></com.example.MyIconPreference>

How can I retrieve programmatically the drawable resource or identifier?

如何以编程方式检索可绘制资源或标识符？

Thanks

This is identical to how you can define your custom View and custom View attributes. The mechanism is the same.

这与您定义自定义View和自定义View属性的方式相同。机制是一样的。

You can find an example with View here: Creating Custom Views.

Define it similar to a custom view and retrieve attributes in you implementation.

将其定义为类似于自定义视图，并在您的实现中检索属性。
