        Log.e("vlaue inserting==", "" + detailList.get(i));
        values.put(DETAIL_ID, String.valueOf(detailList.get(i)));
        values.put(COLUMN_HEADING, String.valueOf(detailList.get(i)));
        values.put(COLUMN_IMAGE_DETAIl, String.valueOf(detailList.get(i)));

    }

我认为你必须编写这样的函数并在for循环中为每个列表项调用此函数。

@model BusinessModels.ClientBusinessModel

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}


@using (Html.BeginForm("Client", "Client", FormMethod.Post, new { @class = "leads-creation-form js-leads-creation-formr" }))
{
    @Html.AntiForgeryToken()


    @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div>
            <div>
                <div>
                    @Html.LabelFor(model => model.ModeOfTransport)
                    <div>
                        @Html.DropDownListFor(model => model.ModeOfTransport, new SelectList(ViewBag.TransportList, "Text", "Value"), "")
                    </div>
                </div>
                <div>
                    @Html.LabelFor(model => model.TypeOfContainer)
                    <div>
                        <select id="TypeOfContainer" name="TypeOfContainer">
                        </select>
                    </div>
                </div>
            </div>
        </div>
        <div>
            <button>
                Submit
            </button>
        </div>
}

<script>
    $("#ModeOfTransport").on("change", function(){
        showValue($(this).val());
        $("#TypeOfContainer").empty();
            })

            function showValue(val)
            {
            $.getJSON('@Url.Action("GetContainerList", "Client")' + "&value=" + val, function (result) {

                    var data = result.data;
                    for (var i = 0; i < data.length; i++) {
                        //console.log(data[i].value);
                        $("<option />", {
                            val: data[i].Text,
                            text: data[i].Value
                        }).appendTo("#TypeOfContainer");
                        //$("#TypeOfContainer").append("<option>" + data[i].Value + "</option>")

                    }

                })
            }
</script>

在你的代码中，每次都会更改contentValue，最后只会将最后一项插入数据库，这是完全错误的。

如何使用contentvalue在SQlite中插入（自定义）ARRAY列表？
