在一些app内,很常见上面一个edittext 下面是个listview的界面,在edittext中输入东西,就可以达到搜索当前listview的目的.现在我们首先使用searchview + listview的方式来实现这样的功能
主要就是使用了searchview的onQueryTextChange内容改变的时候监听 以及onQueryTextSubmit点击了searchview右侧的确定搜索按钮监听
listview主要用到的是,允许listview进行过滤lv_main.setTextFilterEnabled(true);
以及为listview添加过滤 lv_main.setFilterText(newText);// 设置过滤词组
lv_main.clearTextFilter();// 清除listview的过滤
自我感觉没有edittext + listview的方式好,个人推崇后者
