java - 我的 switch 语句没有返回任何内容？

Question

我从警报对话框中选择“Left”，并将其放入 ConvertStatusToCode 函数后应该重新运行“4”，但事实并非如此？

final String[] status = {"Left"};

AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setTitle("Pick a Status");
builder.setItems(status, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        BookingStatus = convertStatusToCode(status[which]);

这是我的convertStatusToCode函数，但它没有重新调整它应该返回的“4”。

private String convertStatusToCode(String status) {

    switch (status) {
        case "Processing":
            i = "0";
            break;
        case "Room is Allotted":
            i = "1";
            break;
        case "Sorry All Rooms Are Full":
            i = "2";
            break;
        case "Living":
            i = "3";
            break;
        case "Left":
            i = "4";
            break;
    }
    return i;
}

它应该看起来像这样

  String getStatusCode(String status) {
        switch (status) {
            case "Processing":
                return "0";
            case "Room is Allotted":
                return "1";
            case "Sorry All Rooms Are Full":
                return "2";
            case "Living":
                return "3";
            case "Left":
                return "4";
            default:
                return "default_value";
        }
    }
