效果图:点击搜索框将搜索的历史在流式布局中展示出来,清空历史记录就会将历史清空,每次搜索后都存入sp中,每次进入页面都先判断sp里是否有值并展示
首先需要导入一个module，下载地址
下载完这个工程后,需要将里面的flowlayout-lib导入到工程中,
导入工程的步骤:File - New - Import Module 选中这个flowlayout-lib
导入完成后,在项目的build.gradle中对导入的module进行依赖
compile project(':flowlayout-lib') activity_main.xml
tv.xml
drawable下面创建
checked_bg.xml
<?xml version="1.0" encoding="utf-8"?>
normal_bg.xml
<?xml version="1.0" encoding="utf-8"?>
tag_bg.xml
<?xml version="1.0" encoding="utf-8"?>
text_color.xml
<?xml version="1.0" encoding="utf-8"?>

super.handleMessage(msg);

final SharedPreferences preferences = getSharedPreferences("config", 0);
final SharedPreferences.Editor editor = preferences.edit();
strings = new ArrayList<>();
final String string = preferences.getString("string", " ");
String[] split = string.split(" ");
if (split.length>0&&!string.equals(" ")){
for (int i=0;i set = new ArraySet<>();
set.add(aa);
historylist.add(aa);
a++;
history+= aa+" ";
