所以我试图掌握在Android中使用自定义控件.但我的应用程序在尝试创建活动时崩溃了.这是代码:

package com.myApp;
import android.content.Context;
import android.widget.EditText;
import android.view.View;
import android.view.View.OnClickListener;

public class MyEditText extends EditText implements OnClickListener {

    public MyEditText(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }   
    public void FlashBorder()
    {
        //do some custom action
    }
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        EditText txt = (EditText) v;
        txt.selectAll();
    }
}

这是布局xml:

<com.myApp.MyEditText
     android:id="@+id/edtTaskName"
     android:layout_height="wrap_content"
     android:layout_width="match_parent"/> 

我在这里有点困惑.如果我将变量传递给json_decode,它不起作用:

$stringJSON = $_GET['jsonstring'];  
echo $stringJSON;
$stringObject = json_decode($stringJSON);
var_export($stringObject);

第一个回显正确地向我显示了我传递的JSON字符串,例如

{\"Items\":[{\"Name\":\"name\",\"Description\":\"\"],\"Name\":\"Christmas\"}

第二个回显显示NULL.所以我从第一个echo中获取字符串并编写以下代码:

$stringObject = json_decode("{\"Items\":[{\"Name\":\"name\",\"Description\":\"\"],\"Name\":\"Christmas\"}");
var_export ($stringObject);

那你怎么说,它向我展示了正确解码的数组.字符串绝对相同,我甚至保留了转义字符.或者也许他们是问题？

我正在尝试用iPhone拍摄基本照片.我使用以下代码显示相机:

 - (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
                                       usingDelegate: (id <UIImagePickerControllerDelegate,
                                                       UINavigationControllerDelegate>) delegate {

        if (([UIImagePickerController isSourceTypeAvailable:
              UIImagePickerControllerSourceTypeCamera] == NO)
            || (delegate == nil)
            || (controller == nil))
            return NO;


        UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
        cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;

        // Displays a control that allows the user to choose picture or
        // movie capture, if both are available:
        cameraUI.mediaTypes =
        [UIImagePickerController availableMediaTypesForSourceType:
         UIImagePickerControllerSourceTypeCamera];

        // Hides the controls for moving & scaling pictures, or for
        // trimming movies. To instead show the controls, …

我在我的应用程序中使用SOAP记录我的用户.但后来我想使用Analytics API,即REST.但我不希望他们再次输入他们的证书.有没有办法可以使用我已经获得的SOAP sessionId作为REST API的令牌？当我尝试这样做时,我从REST调用中收到了身份验证错误.我错过了什么或者是不可能吗？

NSDate *date = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init];
[dateFormat setDateFormat:@"MM/dd/yyyy"];
NSLog([@"today is " stringByAppendingString:[dateFormat stringFromDate:date]]);
NSLog([@"firstBirthdayDate is " stringByAppendingString:[dateFormat stringFromDate:firstBirthdayDate]]);
NSLog([@"secondBirthdayDate is " stringByAppendingString:[dateFormat stringFromDate:secondBirthdayDate]]);
if ([firstBirthdayDate isEqualToDate:secondBirthdayDate])
    NSLog(@"First date is the same as second date");
if (firstBirthdayDate < date)
    NSLog(@"First date is earlier than today");
else
    NSLog(@"First date is later than today");

if (secondBirthdayDate < date)
    NSLog(@"Second date is earlier than today");

• 今天是11/08/2012
• firstBirthdayDate 是01/23/2012
• secondBirthdayDate 是01/23/2012

这是我在日志中得到的:

第一个日期与第二个日期相同

第一次约会比今天晚

第二次约会早于今天

我想我疯了......

我正在使用VSTO开发Excel插件。我刚遇到一个奇怪的问题，如果我尝试从CustomProperties中获取一个值，它将引发COM异常，我也不知道为什么。有人碰到这个吗？这是我要使用的代码：

CustomProperties properties = worksheet.CustomProperties;
properties.Add("name", "value");
Console.Write(properties["name"]); //this crashes COMException. Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH))
Console.Write(properties[0]); //and this crashes COMException.Exception from HRESULT: 0x800A03EC
Console.Write(properties.Item[0]); //and this also crashes Exception from HRESULT: 0x800A03EC
Console.Write(properties.Item["name"]); //and this crashes as well Type mismatch.
Console.Write(properties.get_Item(0)); //this crashes again HRESULT: 0x800A03EC
Console.Write(properties.get_Item("name"); //and this still crashes Type mismatch.

我不知道如何使用此收藏集。我找到了一种解决方法来读取属性：

Dictionary<string, string> workingProperties = new Dictionary<string, string>();
foreach (dynamic custProp in properties)
   workingProperties.Add(custProp.Name, custProp.Value);
string value = workingProperties["name"];// this works

但是，当涉及到更新现有属性时（我很困惑），我需要一种方法来解决该集合中的一个项目，并且没有删除或删除功能来先删除它，然后添加一个具有相同名称的新属性。
