Java Switch语句在嵌套类型中失败

我有以下开关：

我的groupPosition为0，childPosition为1：

switch (groupPosition) {
            case 0:
                switch (childPosition) {
                    case 0:
                        if (NetworkManager.isNetworkAvailable(this)) {
                            new UserAwayTask().execute();
                        } else
                            Toast.makeText(this, "Network not available", Toast.LENGTH_LONG).show();
                        break;

                    case 1:
                        selection = null;
                        selectionArgs = null;
                        break;
                    case 2:
                        selection = Employee.COL_COUNTRY + " IS ? COLLATE NOCASE";
                        selectionArgs = new String[]{valueReceived};
                }
            case 1:
                selection = Employee.COL_DEPARTMENT + " IS ? COLLATE NOCASE";
                selectionArgs = new String[]{valueReceived};
                break;
            case 2:
                empIDList = GetAllTeamLeaders.teamLeaders(this, TeamLeader.COL_TEAMMEMBERID, TeamLeader.COL_TEAMLEADERNAME + " IS ? ", new String[]{valueReceived});
                selection = Employee.COL_EMPID + " IN (" + TextUtils.join(",", Collections.nCopies(empIDList.size(), "?")) + ")";
                selectionArgs = empIDList.toArray(new String[empIDList.size()]);
                break;
        }

但每次我的选择是：系是？整理NOCASE 选择参数来自外部开关的情况1

因此：

 case 1:
                selection = Employee.COL_DEPARTMENT + " IS ? COLLATE NOCASE";
                selectionArgs = new String[]{valueReceived};
                break;

正在执行，而不是：

case 2:
                        selection = Employee.COL_COUNTRY + " IS ? COLLATE NOCASE";
                        selectionArgs = new String[]{valueReceived};

但是，如果我评论外部开关的情况1和情况2。我得到了想要的结果

我错过了什么

您忘记为顶级案例0添加中断：

没有休息；，流只是继续并进入下一个case块，直到它到达break语句或直到它退出开关

---

另外，为嵌套的案例2添加一个中断也不错，以防将来添加更多案例，最终可能会出现与此相同的问题，顺便说一下，这就是所谓的故障。

您不会从外部开关案例0中断。在内部开关的闭合支架上添加一个断路器

case 0:
    switch (childPosition) {
    //
    } break;

---

您缺少休息时间：

switch (groupPosition) {
    case 0:
        switch (childPosition) {
            ...
        }
        break; // <-- here
    case 1:
        selection = Employee.COL_DEPARTMENT + " IS ? COLLATE NOCASE";
        selectionArgs = new String[]{valueReceived};
        break;
    case 2:
        empIDList = GetAllTeamLeaders.teamLeaders(this, TeamLeader.COL_TEAMMEMBERID, TeamLeader.COL_TEAMLEADERNAME + " IS ? ", new String[]{valueReceived});
        selection = Employee.COL_EMPID + " IN (" + TextUtils.join(",", Collections.nCopies(empIDList.size(), "?")) + ")";
        selectionArgs = empIDList.toArray(new String[empIDList.size()]);
        break;
}

---

案例0缺少break语句：案例0中的switch语句后面需要一个分号和break，否则它将在完成时转到案例1。我错过了！恐惧！感谢你，我无法用语言表达我对你的感激之情：

switch (groupPosition) {
    case 0:
        switch (childPosition) {
            ...
        }
        break; // <-- here
    case 1:
        selection = Employee.COL_DEPARTMENT + " IS ? COLLATE NOCASE";
        selectionArgs = new String[]{valueReceived};
        break;
    case 2:
        empIDList = GetAllTeamLeaders.teamLeaders(this, TeamLeader.COL_TEAMMEMBERID, TeamLeader.COL_TEAMLEADERNAME + " IS ? ", new String[]{valueReceived});
        selection = Employee.COL_EMPID + " IN (" + TextUtils.join(",", Collections.nCopies(empIDList.size(), "?")) + ")";
        selectionArgs = empIDList.toArray(new String[empIDList.size()]);
        break;
}
