老规矩，先上图：

功能描述：①用户搜索功能，存本地历史记录；②采用流式布局

存储方式：采用SharedPreferences

优点：避免使用本地数据库导致项目更新版本升级版本号问题，避免sql常规操作失误引发的bug问题。简单实用

一布局：

样式解析，部分图片资源什么的，大家自己替换下即将

布局中用到的自定义控件:(PullToRefreshScrollView就不提供了，这块大家注释掉吧)

自定义的edit，可以让光标一直显示在后面。

补充：BaseActivity 是我自己封装的界面，大家可以替换成原始的Activity，没任何影响。

三精髓剖析：

自己先建立一个缓存，存用户id,作为唯一标识，登录时候就存。我没给提供PreferenceCache这个类，大家可以先按正规操作去处理，或者临时写个：“abc”.

防止输入的edit输入了表情符号等诡异内容，因为在正规搜索的时候，我们第一是要存本地缓存，第二是将输入内容传到服务器做关联查询，防止服务器这边java后端未做处理导致的异常，我们在移动端提前预判一下。

一进到页面，查这个缓存里，有没有东西，有的话，就循环找处理，添加到最开始我们放的全局的vip这个list里，命名有点随意了，见谅。

这两个方法按注释描述执行即可，需要加，一个是增加了搜索的焦点，能让你操作edit很省心，二是唤起键盘时候，把键盘的换行按钮改写为搜索，因为有的需求没有搜索按钮。

删除按钮的显隐，没什么大用这玩意。也是为了满足需求写的。

搜索内容不为空的情况下，图中的“小猫”是为了显示无数据时候的占位图，只是为了测试逻辑，这里你可以按自己实际需求替换，这可以理解为：当你输入了内容，点击了搜索，把输入内容传入服务，调用服务器返回了成功情况下，无查询到数据，那么显示占位图。

下方的String text 是输入的内容，oldText是从本地缓存拿到的历史内容，如果输入的内容在历史记录里有，不存并提示，否则存进去。，存这个拼接的。这个是指，你心里有没有我的方法。

清空。很简洁了。清空完了刷新数据，给吐司提示。

填充数据，常规写法。就这么去动态设置文本的间距样式吧。

总结：

没什么总结的了，肯定好用。切换用户账号是好用的，博主采用了3个手机号登录，输入了不同的搜索内容，切换账号登录均能显示对应的历史记录，清空操作也好用，清除的是单独的用户的搜索记录。有问题欢迎留言，代码写的粗糙了点，只为实现功能，等项目有了服务器数据，再二次封装优化。

重点：

图中老的历史数据要转换成List之后再去比较，否则在执行 contains方法时候会被包含。
