我必须为菜单项添加自定义图标.请任何人建议我？我已经使用CSS类设置了图标但是没有显示.

<p:submenu label="Administration" >
    <p:menuitem value="Role Master" url="/secured/role_master.xhtml?redirect=true" />
    <p:menuitem value="Role Assignment" url="#" />
    <p:menuitem value="User Management" url="/secured/users.xhtml?redirect=true" icon="user"/>
</p:submenu>

以下代码代表css类

.user{
    background: url('resources/images/menu/users.png') no-repeat;
    height:16px;
    width:16px;
}

我想每 5 分钟向用户发送一次通知，我正在使用以下代码。它第一次向我显示通知，但下次不给。

public void startAlarm() {
    AlarmManager alarmManager = (AlarmManager) this.getSystemService(this.ALARM_SERVICE);
    long whenFirst = System.currentTimeMillis();         // notification time
    Intent intent = new Intent(this, NotifyUser.class);
    PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0);
    alarmManager.setRepeating(AlarmManager.RTC, whenFirst, 60*5000, pendingIntent);            
}

public class NotifyUser extends Service {   
    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        loadNotification(); 
    }

    private void loadNotification() {
        NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notify = new Notification(R.drawable.ic_launcher/*android.R.drawable.stat_notify_more*/, "Hanumanji …

在尝试了几乎每一个关于这个问题的回答后,我都没有找到解决问题的方法.

问题:所以我AFNetworking 2.0.3在移植之后使用以下内容实现了我的应用程序的上传部分AFNetworking 1.3:

-(void)commandWithParams:(NSMutableDictionary*)params onCompletion:(JSONResponseBlock)completionBlock {

    NSData* uploadFile = nil;
if ([params objectForKey:@"file"]) {
    uploadFile = (NSData*)[params objectForKey:@"file"];
    [params removeObjectForKey:@"file"];
}

 AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"http://54.204.17.38"]];

 manager.responseSerializer = [AFJSONResponseSerializer serilizer];
 manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"];

 AFHTTPRequestOperation *apiRequest = [manager POST:@"/API" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

     if (uploadFile) {
         [formData appendPartWithFileData:uploadFile name:@"file" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
     }

} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    completionBlock(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    completionBlock([NSDictionary dictionaryWithObject:[error localizedDescription] forKey:@"error"]);
}];

[apiRequest start];

} …

String temp_date="07/28/2011 11:06:37 AM";  
Date date = new Date(temp_date); //Depricated 
SimpleDateFormat sdf = new SimpleDateFormat("MMM-dd-yyyy hh:mm:ss"); 
String comp_date= sdf.format(date);
System.out.println(comp_date);

这有效,但如果我使用这样的东西

String temp_date="07/28/2011 11:06:37 AM";  
try{  
    SimpleDateFormat sdf = new SimpleDateFormat("MMM-dd-yyyy hh:mm:ss"); 
    Date comp_date= sdf.parse(temp_date);
    System.out.println(comp_date);
}catch(Exception e){
    System.out.println(e);
}

抛出此异常:

java.text.ParseException: Unparseable date: "07/28/2011 11:06:37 AM"

我正在尝试通过使用该setOnClickFillInIntent方法使我的ListView Widget中的listrows可单击,但每当我单击ListItem时都没有发生任何事情.以下是我的代码的一些关键部分:

Intent i = new Intent();
Bundle extras = new Bundle();

extras.putInt(Resource.WIDGET_PACKAGE, position);
i.putExtras(extras);
row.setOnClickFillInIntent(R.id.widget_layout_parent, i);

这是getView()我的ViewFactory 的结尾.Resource.WIDGET_PACKAGE包含我的包名称,就像任何其他键一样.位置int来自getView()参数.R.id.widget_layout_parent是所有列表项中的父布局.

这是我的WidgetProviders的结束 onUpdate()

Intent clickIntent = new Intent(context, ItemListActivity.class);

PendingIntent clickPI = PendingIntent.getActivity(context, 0,
        clickIntent, PendingIntent.FLAG_UPDATE_CURRENT);

widget.setPendingIntentTemplate(R.id.widget_layout_parent, clickPI);

appWidgetManager.notifyAppWidgetViewDataChanged(appWidgetIds[i],
        R.id.widget_list_view);

有什么我想念的,或者你还有什么想知道的吗？

所有帮助表示赞赏!:)

我下面有简单的脚本,

if [ ! -e $c ];
then
mkdir "$c"
fi

$ c包含文件夹路径.我收到错误mkdir:command not found.请帮帮我.

我正在尝试解析日期字符串到日期但无法解析.它显示了一些例外

码

Date date = null;
String dtStart = "2013-11-08 05:46:55" ;  
SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    date = format.parse(dtStart);  
    System.out.println("Date ->"+date);  
} catch (ParseException e) {  
    // TODO Auto-generated catch block  
    e.printStackTrace();  
}

Stacktace:

11-08 19:04:06.394: W/System.err(8659): java.text.ParseException: Unparseable date: "2013-11-08 05:46:55"
11-08 19:04:06.402: W/System.err(8659):     at java.text.DateFormat.parse(DateFormat.java:626)

请给出一些解决方案
