Instead of Viewuse ViewGroupto extend your CustomViewclass..
而不是View使用ViewGroup扩展您的CustomView类..
A ViewGroupis a special view that can contain other views (called children.) The view group is the base class for layouts and views containers.
甲的ViewGroup是一个可以包含其它视图的特殊视图（称为孩子）的视图组用于布局和视图容器的基类。
Something Like,
就像是，
public class MyView extends ViewGroup
Now, you can use method called
现在，您可以使用称为
public void addView (View child)
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.
添加子视图。如果尚未在 child 上设置布局参数，则在 child 上设置此 ViewGroup 的默认参数。

You can't add child to view. Only to ViewGroup
您不能添加孩子来查看。仅适用于 ViewGroup
