Android 開發 實現文本搜索功能

核心邏輯方法:

/**
     * 搜索item
     * @param searchContent 須要搜索的文本內容
     */
    public void searchItem(String searchContent){
        this.mSearchContent = searchContent.trim();//去除空格
        if(TextUtils.isEmpty(mSearchContent)||mSearchContent.length()==0){//若是搜索內容是空的就顯示所有內容
            this.mShowList.clear();
            mShowList.addAll(mAllDataList);
            notifyDataSetChanged();
            return;
        }
        List<THealthDataListBase.StudentData> tempList = new ArrayList<>();//用於臨時保存匹配完成的數據
        THealthDataListBase.StudentData tempStudentData = null;//用於臨時保存匹配完成的item數據
        char[] searchContentCharArray = searchContent.toCharArray();
        for (THealthDataListBase.StudentData studentData : mAllDataList){ //遍歷所有學生名稱
            char[] studentNameCharArray = studentData.name.trim().toCharArray();//學生名稱去除空格,而且轉成數組
            int count = 0;
            for (int i=0;i<searchContentCharArray.length;i++){ //遍歷搜索文字
                for (char word :studentNameCharArray){ //遍歷學生名稱文字
                    if (word == searchContentCharArray[i]){ //判斷一致的文字
                        count++;
                    }
                }

            }
            if (count == 0){ //若是匹配度是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();
        mShowList.addAll(tempList);
        notifyDataSetChanged();

    }
