New Android journey (11) Insert a new view into the existing page

In some specific situations, you cannot use static methods to define the view used in the page. For example, a custom graph is an independent view. To insert it into a page as a part, you need the following methods:

Linearlayout L = new linearlayout (this); // L indicates the current page layout.

L. addview (myview); // Add a new view
L. setpadding (20,390, 20, 40); // set the position
Linearlayout. layoutparams P = new linearlayout. layoutparams (linearlayout. layoutparams. wrap_content, linearlayout. layoutparams. wrap_content );
L. setlayoutparams (p); // parameters of the new view
This. addcontentview (L, P); // Add a new view
