推荐答案

而不是查看使用的ViewGroup 延长你的 CustomView 类..

Instead of View use ViewGroup to extend your CustomView class..

一个的ViewGroup 是一种特殊的视图，可以包含其他视图（称为儿童）的视图组是布局和视图的容器基类。

A ViewGroup is a special view that can contain other views (called children.) The view group is the base class for layouts and views containers.

像，

public class MyView extends ViewGroup

现在，你可以使用的方法称为

Now, you can use method called

public void addView (View child)

添加一个子视图。如果没有布局参数对孩子已经设置，默认参数的ViewGroup这是对孩子进行设置。

Adds a child view. If no layout parameters are already set on the child, the default parameters for this ViewGroup are set on the child.
