我有一个自定义内部的布局,ViewPager不会垂直滚动.自定义ScrollView用于修复使用ScrollView滑动的可怕选项卡.ViewPagerScrollView

是的,有足够的内容可以滚动,我尝试使用和不使用底部按钮.

我正在使用具有3个选项卡的ActionBar,当前代码允许向左/向右滑动就好了.

我的目标是为一些动作项目设置底部栏,例如保存和取消,以及ActionBar和底部按钮之间的部分是将垂直滚动的ViewPager.

我尝试过太多组合,现在正在给你寄这封情书.有任何想法吗？如有需要,欢迎任何帮助,并随时询问其他详细信息.

下面是ListView一行太短的图像.我尝试了太多组合,让我对StackOverflow感到沮丧.

我该如何修复此问题并显示整行？这是项目的XML.

1. 这个错误是什么意思？
2. 既然应用程序继续工作,我应该忽略它吗？
3. 我该如何解决？

当我在此处发布的例程后从手机图库中选择图像时,会发生这种情况.正是当我按下活动布局中定义的浏览图库按钮时.

我在网页上工作,在其中我使用了一个背景图片,我希望将其拉伸到窗口的整个宽度,因为我有文字,我想要处于固定位置,无论什么屏幕分辨率是.我正在寻找一个CSS实现,但如果Javascript是我最好的选择,我会鼓励使用它.

这是我的页面的样子:http://dl.dropbox.com/u/9134840/demo/windowsxp.html

除非您使用1080p显示器,否则背景图像不会从边缘到边缘完全延伸,并留下一点空白.任何帮助,将不胜感激.

嗨,我正在做一个Android gps教程,我收到一个错误,我不明白(我是Android开发新手).我得到了错误

position = (WebView) findViewById(R.id.activity_main);

哪里activity_main似乎是问题.有人可以解释问题是什么吗？谢谢.

import android.R;
import android.app.Activity;
import android.location.Location;
import android.os.Bundle;
import android.webkit.WebView;
import android.widget.Toast;

public class GPSActivity extends Activity
{
    WebView position;
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_list_item);

        position = (WebView) findViewById(R.id.activity_main);
        position.getSettings().setJavaScriptEnabled(true);

    }

    public void onLocationChanged(Location loc)
    {
        String Text ="My current location is: " + "Latitud="
                + loc.getLatitude() + "Longitud =" + loc.getLongitude();
        Toast.makeText(getApplicationContext(), Text, Toast.LENGTH_LONG).show();

        String url ="http://maps.google.com/staticmap?center="
                + loc.getLatitude() +loc.getLatitude()
                + "&zoom=14&size=512x512&maptype=mobile/&markers="

我收到此错误（我正在使用 Oracle.DataAccess dll）：

{Oracle.DataAccess.Client.OracleConnection}

(Oracle.DataAccess.Client.OracleException).DataSource threw an exception of type 'System.NullReferenceException'

堆栈跟踪 ：

   at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode,
OracleConnection conn, IntPtr opsErrCtx, Object src)
   at Oracle.DataAccess.Client.OracleConnection.Open()

代码：

 using (OracleConnection conn = new OracleConnection(ConfigurationManager.ConnectionStrings["myConnection"].ConnectionString))
            {
                using (OracleCommand cmd = conn.CreateCommand())
                {
                    cmd.CommandText = "<<Procedure Name>>";
                    cmd.Parameters.Add("v_cur", OracleDbType.RefCursor).Direction = ParameterDirection.Output;

                    conn.Open(); --line throws exception
                    using (OracleDataReader reader = cmd.ExecuteReader())
                    {

                        {
                            retVal = reader["VALUE"].ToString();
                        } …

我试图将变量传递到 requests.post() 中的数据字段，但我继续收到错误，

  Error Response: {'error': {'message': 'Exception while reading request', 
'detail': 'Cannod decode: java.io.StringReader@1659711'}, 'status': 'failure'}

这是我的代码

#Fill array from CSV
temp=[]
for row in csv.iterrows():
    index, data = row
    temp.append(data.tolist())


#Create new asset for all assets in CSV
for index, row in enumerate(temp):
    make = temp[index][0]
    serial = str(temp[index][1])
    date = str(temp[index][2])
    response = requests.post(url, auth=(user, pwd), headers=headers, 
    data='{"asset_tag":"test1", "assigned_to":"test2", 
    "company":"test3", "serial_number":serial}')

我最初尝试使用直接从 CSV 提供数据

str(temp[index][1])

这不起作用，所以我尝试分配str(temp[index][1])给变量serial，然后像这样传递变量，但这也会导致相同的错误。

如果能找到正确的方向就太好了，谢谢！

新手在这里.对不起,谢谢.我需要找到不等于'Ok'的记录.此代码不起作用.

是否有与Perl相同的MySql ne？

use DBI;

SELECT * FROM people WHERE status ne 'Ok'
