我正在使用我的Angular 4项目的默认i18n进程,所以我ng-i18n用来生成.xlf没有问题.

但是根据我的打字稿代码,我还有一些文本需要翻译并通过id检索当前语言.

在Angular 4中我找不到任何方法.我错过了什么吗？如果那件事,我正在使用AOT.

如果服务器从Web服务发回一些消息/错误代码,如何使用Angular转换它们,也会出现此问题

我创建了一个build.gradle来增加发布版本上的prod版本代码以及我想要的所有未来项目的其他配置,有没有办法告诉Android Studio(或者intelliJ)将build.gradle用于所有新项目我创建 ？或者也许是IDE使用模板我可以修改的gradle文件？

我使用这个库 ( https://github.com/socketio/socket.io-client-java ) 将我的 Android 应用程序与我的 Sails socket.io 连接起来。

这是我使用的代码：

final Socket socket = IO.socket(Constants.LOCAL_URL+"?__sails_io_sdk_version=0.11.0");
socket.on(Socket.EVENT_CONNECT, new Emitter.Listener()
            {

                @Override
                public void call(Object... args)
                {
                    JSONObject obj1 = new JSONObject();
                    try {
                        obj1.put("url","/rest/room");
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                    socket.emit("get", obj1, new Ack() {
                        @Override
                        public void call(Object... args) {
                            Log.e("test", "GET");
                        }
                    });
                    Log.e("test", "CONNECT");
                }

            }).on("room", new Emitter.Listener()
            {
                @Override
                public void call(Object... args)
                {

                    Log.e("test", "ROOM");
                }
            });

但是我有一个 403 原因 URL 需要身份验证。那么如何修改套接字标头以放置Cookie并保持套接字和 …

我正在尝试用服务器渲染angular2-universal.我复制粘贴官方repo https://github.com/angular/universal/tree/master/examples/src/universal/todo的示例todo应用程序到我自己的Trails/Express服务器.

我设法启动我的服务器,但当我打电话时,http://localhost:3000我有以下错误:

普遍回购的例子正在运作,所以我不明白为什么它不适合我.我没有更改angular2源上的任何内容.

我的所有代码都在https://github.com/jaumard/trails-angular2-isomorphic这里配置https://github.com/jaumard/trails-angular2-isomorphic/blob/master/api/controllers/ViewController. js#L58用于路由,此处用于模板引擎https://github.com/jaumard/trails-angular2-isomorphic/blob/master/config/web.js#L76

我试图在我的Android应用程序上使用dagger 2从arch android库注入新的ViewModel。

从我在此示例上看到的https://github.com/googlesamples/android-architecture-components/tree/e33782ba54ebe87f7e21e03542230695bc893818/GithubBrowserSample我需要使用以下代码：

@MustBeDocumented
@Target(AnnotationTarget.FUNCTION, AnnotationTarget.CONSTRUCTOR, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER)
@Retention(AnnotationRetention.RUNTIME)
@MapKey
internal annotation class ViewModelKey(val value: KClass<out ViewModel>)

@Module
abstract class ViewModelModule {
    @Binds
    @IntoMap
    @ViewModelKey(LoginViewModel::class)
    internal abstract fun bindLoginViewModel(viewModel: LoginViewModel): LoginViewModel

    @Binds
    @IntoMap
    @ViewModelKey(MainMenuViewModel::class)
    internal abstract fun bindSearchViewModel(viewModel: MainMenuViewModel): MainMenuViewModel

    @Binds
    internal abstract fun bindViewModelFactory(factory: ViewModelFactory): ViewModelProvider.Factory
}

@ApplicationScope
@Component(modules = arrayOf(ApplicationModule::class, NetworkModule::class, ViewModelModule::class))
interface ApplicationComponent {
    fun plusActivityComponent(activityModule: ActivityModule): ActivityComponent
    fun inject(application: LISAApplication)

}

我的工厂是：

@ApplicationScope
class ViewModelFactory @Inject constructor(private val creators: Map<Class<out ViewModel>, @JvmSuppressWildcards Provider<ViewModel>>) …

我在谷歌播放崩溃报告上有这个错误,不知道如何解决它:

这是我的代码谁崩溃:

    DataBaseHelper d = new DataBaseHelper(context);
    Cursor c = d.getNotifications(false);
    SharedPreferences preferences;
    String ns = Context.NOTIFICATION_SERVICE;

    NotificationManager mNotificationManager = (NotificationManager)context.getSystemService(ns);

    CharSequence tickerText = "";

    if(c!=null && c.moveToFirst()){ // CRASH HERE :(

        do{
                       .... …

我知道如何知道网络类型:

TelephonyManager telManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
int network_type = telManager.getNetworkType();

但我希望在手机切换到2G到3G或3G到2G时注册...

无论如何要做到这一点？

谢谢你的帮助.问候吉姆

我对ActionBarSherlock有一些问题

在android 4上没关系:

但在Android 2.3上

缺少一个选项!子菜单没有显示以显示此选项.

这就是我创建菜单的方式:

 @Override
public boolean onCreateOptionsMenu(Menu menu) {

    menu.add("Controls")
        .setIcon(R.drawable.ic_launcher)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
    menu.add("Theme")
    .setIcon(R.drawable.ic_launcher)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
    menu.add("Advanced")
    .setIcon(R.drawable.ic_launcher)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
    menu.add("Profils")
    .setIcon(R.drawable.ic_launcher)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
    menu.add("Save")
    .setIcon(R.drawable.ic_launcher)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    return true;
}

我怎样才能解决这个问题 ？

我正在尝试实现一个自动完成字段，但我对泛型有一点问题。这是我的实现：

import 'package:flutter/material.dart';
import 'package:kiwi_mobile/common/presentation/loading.dart';
import 'package:rxdart/rxdart.dart';

typedef AutocompleteDelegate<T> = Future<List<T>> Function(String query);

class AutocompleteField<T> extends StatefulWidget {
  final InputDecoration decoration;
  final FocusNode focusNode;
  final bool autofocus;
  final int maxLines;
  final int itemExtent;
  final TextInputType keyboardType;
  final TextEditingController controller;
  final Widget Function(BuildContext context, T entry) itemBuilder;//Here dynamic instead of T as T doesn't work for some reason....
  final AutocompleteDelegate<T> delegate;
  final Function(T entry) onItemSelected;//Here dynamic instead of T as T doesn't work for some reason....

  const AutocompleteField(
