Java android中的Listview未填充数据

下面是我在c#framework 4.5中的webservice代码，用于检索数据并将其添加到json数组中

[WebMethod(Description = "Webservice for generating category wise report in JSON form")]
public string getCategoryWiseReport(string distr)
{
    string dist = "23";
    distr = dist;
    var con = new SqlConnection("data source=xxxx;initial catalog=xxxxx;integrated security=true");
    StringBuilder JSON = new StringBuilder();
    con.Open();
    var cmd = new SqlCommand();
    cmd.Connection = con;
    cmd.CommandText = "RepSum";
    cmd.CommandType = CommandType.StoredProcedure;
    DataTable dt = new DataTable();
    SqlDataAdapter ad = new SqlDataAdapter(cmd);
    cmd.Parameters.AddWithValue("@dri", dri);
    cmd.ExecuteNonQuery();
    ad.Fill(dt);


    JSON.Append("{");
    JSON.Append("\"Report\":[");
    for (int i = 0; i <= (dt.Rows.Count - 1); i++)
    {
        for (int j = 0; j <= 8; j++)
        {
            JSON.Append("{");
            JSON.Append("\"code\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"desg\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"name\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"name\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"complaint_re\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"omplaint_d\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"complaint_pg\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"complaint_im\":\"" + dt.Rows[i][j].ToString() + "\", ");
            JSON.Append("\"omplaint_t\":\"" + dt.Rows[i][j].ToString() + "\", ");
        }

        if (JSON.ToString().EndsWith(","))
        {
            JSON = JSON.Remove(JSON.Length - 1, 1);
        }

        JSON.Append("]}");
    }
    con.Close();
    return JSON.ToString();

}
