《Android基于PinnedSectionListView实现联系人通讯录》

我在之前的文章中写过文章,介绍过PinnedSectionListView(文章地址链接: http://blog.csdn.net/zhangphil/article/details/47144125 )【文1】,也有一篇文章是关于Android通讯录联系人操作的基础知识(文章地址链接: http://blog.csdn.net/zhangphil/article/details/47250747 )【文2】。【文1】和【文2】作为进一步做Android联系人通讯录的准备工作。
现在基于PinnedSectionListView,实现一个目前较为流行的、能够说明Android通讯录联系人的大体模型外架。

如图:


测试用的MainActivity.java :

			int letter = A + i;

				}
			}
		}

		PinnedSectionListView listView = (PinnedSectionListView) this
				.getListView();

		listView.setAdapter(new MyAdapter(this, -1, items));

		// 增加点击事件,当用户点击ListView的item时候,打电话。
