我有一个有3个字段的表
ID Tax State
0 .50 TX
1 .25 TX
2 .25 AZ
3 .25 AZ
4 .1 AL
我想为每个州提取税金.
Tax State
.75 TX
.5 AZ
.1 AL
如何编写查询来执行此操作？
我试图从我的发布数据发送到我的服务器的图像从android.为了实现这一点,我将64位编码的我的图像编码为字符串并使用android volley库发送它.但这会引起问题.由于某种原因,它有时会发送两次帖子,我无法弄清楚原因.下面是调用发送post请求的函数.我在那里放了一个破记标记,String url = "http://domain.com/ajax_ws.php";然后在protected Map<String, String> getParams() {我发现的String url = ...内容中只有一个被调用一次但是当它发送两个时,它protected Map...被调用两次.我在android排球上找不到任何文档,所以我不知道为什么会这样.调整位图大小,使图像字符串始终保持在100k到200k字符之间.我想也许这是一个大小问题,但我的服务器正在接收图像并解码它们,一切都很好.
public void Sharing() {
pd = ProgressDialog.show(getParent(), null, "Please Wait...");
final String caption = mEtMessage.getText().toString();
RequestQueue queue = Volley.newRequestQueue(this);
String url = "http://domain.com/ajax_ws.php";
StringRequest postRequest = new StringRequest(
Request.Method.POST,
url,
new MyStringListener(),
new MyErrorListener()
) {
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("token", "secretToken");
params.put("mode", "createVoucher");
params.put("user_id", ActivityLogin.id);
params.put("deal_id", ActivitySharing.id_deal);
params.put("user_id_company", ActivityRestaurantDetails.res.getId()); …我创建了一个带有iPad故事板的应用程序,但我们决定不支持iPad.我需要在项目中的某处禁用它,还是删除它？在创建项目后似乎无法找到有关编辑它的任何信息.
我在实施分段控制时遇到了麻烦.我相信我已经连接了所有内容,但是当我点击分段控件的任一侧时,该方法没有被调用.

在 bar.html 示例文件中，有以下代码：

谢谢!
以下是代码布局的概述
<html style="overflow:hidden;">
<head></head>
<body>
<div id="content">
<div class="container2">
<div class="fullwidthbanner-container" style="width: 100% !important; overflow: hidden; position: relative; padding: 0; max-height: 500px !important;">/*stuff in here*/
</div>
<div class="container" style="width: 1030px; margin: 0 auto;">/*stuff in here*/
</div>
</div>
</div>
</body>
</html>
我希望只有当某人的窗口小于容器div的1030px时才会显示滚动条.如果我采取溢出:隐藏; 在html中,滚动条显示出来像每个人都说的那样.但是,由于与fullwidthbanner-container div有关,min-width对身体不起作用.
