核心逻辑方法:
/**
* 搜索item
* @param searchContent 需要搜索的文本内容
*/
public void searchItem(String searchContent){
this.mSearchContent = searchContent.trim();//去除空格
if(TextUtils.isEmpty(mSearchContent)||mSearchContent.length()==0){//如果搜索内容是空的就显示全部内容
this.mShowList.clear();
mShowList.addAll(mAllDataList);
notifyDataSetChanged();
return;
}
List<THealthDataListBase.StudentData> tempList = new ArrayList<>();//用于临时保存匹配完成的数据
THealthDataListBase.StudentData tempStudentData = null;//用于临时保存匹配完成的item数据
char[] searchContentCharArray = searchContent.toCharArray();
for (THealthDataListBase.StudentData studentData : mAllDataList){ //遍历全部学生名称
char[] studentNameCharArray = studentData.name.trim().toCharArray();//学生名称去除空格,并且转成数组
int count = 0;
for (int i=0;i<searchContentCharArray.length;i++){ //遍历搜索文字
for (char word :studentNameCharArray){ //遍历学生名称文字
if (word == searchContentCharArray[i]){ //判断一致的文字
count++;
}
} }
if (count == 0){ //如果匹配度是0就不添加
continue;
}
tempStudentData = new THealthDataListBase().new StudentData();
tempStudentData.name = studentData.name;
tempStudentData.studentId = studentData.studentId;
tempStudentData.morning = studentData.morning;
tempStudentData.noon = studentData.noon;
tempStudentData.setCount(count);
tempList.add(tempStudentData); }
if (tempList.isEmpty() && !mSearchContent.isEmpty()){
mShowList.clear();
notifyDataSetChanged();
return; }
Collections.sort(tempList);//排序
mShowList.clear();
