Activity.setContentView，View.setContentView？ [英] Activity.setContentView, View.setContentView?

问题描述

我注意到，活动类具有其中一个xml资源文件可以被加载的setContentView方法。我想做同样的事情，从查看最终继承的类。这似乎是一个死胡同，因为的setContentView方法不适用于View类存在。

I noticed that the Activity class has a setContentView method where an xml resource file can be loaded. I wanted to do the same thing with a class that inherits ultimately from View. This seemed to be a dead end because the setContentView method does not exist for the View class.

这导致了两个问题：

1）是否有可能查看的加载在可视化布局编辑器中创建的布局？

1) Is it possible for View's to load layouts created in the Visual Layout Editor?

2）如果不是，为什么？好像不是允许用户直接加载XML布局到一个视图是一个限制。我期望有为什么在API中未设置的setContentView方法（或类似方法）的一个原因。

2) If not, why? It seems like not allowing users to load an xml layout directly into a View is a limitation. I expect that there is a reason why the setContentView method (or a method similar) is not provided in the API.

在此先感谢！

推荐答案

我觉得LayoutInflator是你在找什么的 http://developer.android.com/reference/android/view/LayoutInflater.html
这里是一个code样品：<​​/ P>

I think that LayoutInflator is what you are looking for http://developer.android.com/reference/android/view/LayoutInflater.html And here is a code sample:

    View view = (View)inflater.inflate(R.layout.abc, null);
    view_group.add(view);
