我需要一个多线布局，这将表现为水平线性布局，但如果没有足够的空间来放置新的widget，将扩大到下一行，就像在文本中的单词。窗口小部件会在运行时被添加在那里，并应与 WRAP_CONTENT 去。其实，就不会有按钮。

I need a multi-line layout, which would behave as horizontal linear layout, but when there is not enough space to place new widget it would expand to next line, just like words in text. Widgets would be added there at runtime, and should go with wrap_content. Actually, there would be buttons.

有没有这样的行为的任何部件？或者给一个有关如何通过自己写这样的布局建议。

Is there any widgets with such behaviour? Or give a suggestion about how to write such layout by myself.

最后，它应该是这样的：

Finally it should look like this:
