 1 | # ViewGroupDemo
 2 | 新闻客户端详情页，上面WebView新闻内容，下面ListView评论，可以上下滑动，类似今日头条，搜狐新闻等
 3 | 
 4 | #####介绍
 5 | 上面展示文章内容用WebView下面展示这个文章的评论用ListView，可以上下滑动来切换文章内容和评论，程序已经发布，经过测试拿来即用
 6 | 
 7 | #####扩展
 8 | 只要实现了IBaseArticleLayout和IBaseCommentLayout接口将这两个View放到ArticleDetailsViewGroup容器中可以自定义其他的上下切换的控件
 9 | 
10 | #####使用方法
11 | MainActivity.java<br>
12 | public class MainActivity extends AppCompatActivity {
13 | 
14 |     @Override
15 |     protected void onCreate(Bundle savedInstanceState) {
16 |         super.onCreate(savedInstanceState);
17 |         setContentView(R.layout.activity_main);
18 |         //一下两个Layout分别实现了IBaseArticleLayout和IBaseCommentLayout接口
19 |         ArticleDetailsLayout articleDetailsLayout = new ArticleDetailsLayout(this);
20 |         ArticleCommentLayout articleCommentLayout = new ArticleCommentLayout(this);
21 | 
22 |         ArticleDetailsViewGroup articleDetailsViewGroup = (ArticleDetailsViewGroup)findViewById(R.id.articleDetailsViewGroup);
23 | 
24 |         articleDetailsViewGroup.addArticleView(articleDetailsLayout);
25 |         articleDetailsViewGroup.addCommentView(articleCommentLayout);
26 |         articleDetailsViewGroup.requestLayout();
27 |     }
28 | }
