		}

		@Override
		public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
				int arg3) {
		}

		@Override
		public void afterTextChanged(Editable arg0) {
		}
	};

搞定,代码量也不是很多,自己做个总结留个笔记,也希望可以帮助到朋友们。


Android小控件之模糊匹配Android小控件之模糊匹配

最近开发中有个需求类似qq搜索功能,根据数字,首字母,全拼,简拼实现数据检索。之前只是根据对象的属性来对比,后来发现有局限性,所以参考一篇博客自己动手修改了一下,实现的结果还比较不错的,在这里分享一下:

效果图1 简拼:

效果2 全拼:

效果3 根据数字搜索:
