过滤2d数组/返回ArrayIndexOutofBoundException

Question

这是我的2d数组的结构以及单个数组

public String[] sList() {
    String list[] = { "Asia Medic Family Hospital and Medical Center",
            "Adventist University of the Philippine Health Service ",
            "Bautista Hospital",
            "Catalan Medical Hospital ", 
            "Catbagan General Hospital",
            "Cavite Center for Mental Health", 
            "Cavite Doctors' Medical Center, Inc",
            "Cavite Medical Center", 
            "Cavite Municipal Hospital",
            "Cavite Naval Hospital", 
            "Contreras Medical Clinic",
            "Crisostomo General Hospital", 
            "DBB Municipal Hospital",
            "DLSU-Dr. Rodolfo Poblete Memorial Hospital ", 
            "De La Salle University Medical Center",
            "Del Rosario Hospital" };
return list;
.....
public String[][] sSpecialty() {
    String list[][] = { 



            {"Specialty 1.0", "Specialty1.1", "Specialty1.2" , " " , " " },
            {"Specialty 2.0", "Specialty2.1", "Specialty2.2" , " " , " "},
            {"Specialty 3.0", "Specialty3.1", "Specialty3.2", "Specialty3.3", " " },
            {"Specialty 4.0", "Specialty4.1", "Specialty4.2", "Specialty4.3", "Specialty4.4" },
            {"Specialty 5.0", "Specialty5.1", "Specialty5.2", "Specialty5.3", "Specialty5.4" },
            {"Specialty 6.0", "Specialty6.1", "Specialty6.2", "Specialty6.3", "Specialty6.4" },
            {"Specialty 7.0", "Specialty7.1", "Specialty7.2", "Specialty7.3", "Specialty7.4" },
            {"Specialty 8.0", "Specialty8.1", "Specialty8.2", "Specialty8.3", "Specialty8.4" },
            {"Specialty 9.0", "Specialty9.1", "Specialty9.2", "Specialty9.3", "Specialty9.4" },
            {"Specialty 10.0", "Specialty10.1", "Specialy10.2", "Specialty10.3", "Specialty10.4" },
            {"Specialty 11.0", "Specialty11.1", "Specialty11.2", "Specialty11.3", "Specialty11.4" },
            {"Specialty 12.0", "Specialty12.1", "Specialty12.2", "Specialty12.3", "Specialty12.4" },
            {"Specialty 13.0", "Specialty13.1", "Specialty13.2", "Specialty13.3", "Specialty13.4" },
            {"Specialty 14.0", "Specialty14.1", "Specialty14.2", "Specialty14.3", "Specialty14.4" },
            {"Specialty 15.0", "Specialty15.1", "Specialty15.2", "Specialty15.3", "Specialty15.4" },
            {"Specialty 16.0", "Specialty16.1", "Specialty16.2", "Specialty16.3", "Specialty16.4" }
};
return list;

我如何过滤这些2d数组，例如我选择Specialty2.2时我有一个项目结果是菲律宾健康服务的Adventist大学，你可以看到它们都在第二个数组列表中。我很好地过滤单个阵列，但是当我添加2d阵列时会遇到问题。

for (int loop = 0; loop < sList.length; loop++) {
        String temp = sTuition[loop];
        theTuitionFee = Integer.parseInt(temp);

        // ALL filter selected
        if (sReg[loop].equalsIgnoreCase(thisFilter[0])
                && sAdmin[loop].equalsIgnoreCase(thisFilter[1])
                && sAmbience[loop].equalsIgnoreCase(thisFilter[3])
                && amountTF >= theTuitionFee
                && sSpecialty[loop][loop].equalsIgnoreCase(thisFilter[5])
                ) {
            list.add(sList[loop]);

我在这部分得到ArrayIndexOutofBoundsException“＆amp;＆amp; sSpecialty [loop] [loop] .equalsIgnoreCase（thisFilter [5]）”任何建议如何摆脱这个问题。

如果您有任何其他方式添加创建的2d数组，那么这是我只使用单个数组的完整程序。

public class SchoolListFragmentFilter extends Fragment implements
    OnItemClickListener {
NavigationDrawer navi = new NavigationDrawer();
String thisFilter[] = NavigationDrawer.theFilter;
int amountTF = NavigationDrawer.TuitionFee;
PSManilaDB conn = new PSManilaDB();
String sList[] = conn.sList();
String sReg[] = conn.sRegAffil();
String sAdmin[] = conn.sAdmin();
String sType[] = conn.sSize();
String sAmbience[] = conn.sAmbience();
String sTuition[] = conn.sTuitionFee();
int theTuitionFee;

    lvList = (ListView) v.findViewById(R.id.lvSchools);
    for (int loop = 0; loop < sList.length; loop++) {

Answer 1

如果我理解正确，sList.length为16，但您的2d数组宽度仅为5.这意味着loop最多为16，但sSpecialty[loop][loop]中的第二个索引必须为小于5.这是您获得IndexOutOfBoundsException的地方。

我认为你需要用

之类的东西替换if语句

// ALL filter selected
boolean filtermatch=false;

for(int subloop=0;subloop<sSpecialty[loop].length;subloop++){
        if (sSpecialty[loop][subloop].equalsIgnoreCase(thisFilter[5])
                ) {
                   filtermatch=true;
        }
}

if(filtermatch && sReg[loop].equalsIgnoreCase(thisFilter[0])
                && sAdmin[loop].equalsIgnoreCase(thisFilter[1])
                && sAmbience[loop].equalsIgnoreCase(thisFilter[3])
                && amountTF >= theTuitionFee;){
    list.add(sList[loop]);
}

第二个循环将第二个索引保持在边界内。
