小编jau*_*ard的帖子

我尝试保存/恢复一组字符串,除了一件事以外一切正常.当我创建我的字符串时,我把:

Set<String> set = new HashSet<String>();
for(int i=0; i<toggles.size();i++){
   set.add(toggles.get(i).serialise());                 
}

订单例如是"blutooth""application""data".当我回来时:

Set<String> set = prefs.getStringSet(key, new HashSet<String>());
for (String toggle : set){
    Toggle t = new Toggle();
    t.deserialize(toggle);
    toggles.add(t); 
}

我得到"应用程序""蓝牙""数据"他们按名称排序,我不想要这个.我希望获得相同的订单.有人可以帮帮我吗？

我正在尝试使用ext/packages/ux/classic/src/colorpicker下的颜色选择器所以我设置了我的要求:

requires: [
        'Ext.plugin.Viewport',
        'Ext.window.MessageBox',


        'ThemeDemoApp.view.main.MainController',
        'ThemeDemoApp.view.main.MainModel',
        'ThemeDemoApp.view.main.List',
        'Ext.slider.Single',
        'Ext.ux.colorpick.Button'
    ]

在app.js的顶部,我设置了这个:

Ext.Loader.setConfig({                enabled : true,
                paths   : {
                        'Ext.ux' : 'ext/packages/ux/classic/src'
                } 
        });

但是我没有工作:无法加载资源:服务器响应状态为404(未找到) http:// localhost:1841/ext/classic/cl ... = 1437726506841

它不需要我的加载程序配置.如何正确配置Ext.ux？

谢谢

我正在尝试使用通用启动器示例来了解有关使用Angular2进行服务器渲染的更多信息,我想使用gulp而不是webpack.问题是服务器启动时我有:

/Users/jaumard/IdeaProjects/trails-angular2-isomorphic/node_modules/@angular/core/src/util/decorators.js:165
        throw 'reflect-metadata shim is required when using class decorators';
        ^
reflect-metadata shim is required when using class decorators

我看到一些帖子谁说要添加,import 'reflect-metadata';但这并没有解决我的问题:(我想我想念一些东西,但无法想象它是什么......这是我使用的代码https://github.com/ jaumard /小径-angular2同构

我正在新创建的项目上使用最新的flutter版本。我正在尝试呼叫这个网址https://jsonplaceholder.typicode.com/users

但是在iOS或Android上，我得到了 flutter: Error SocketException: OS Error: Connection refused, errno = 61, address = jsonplaceholder.typicode.com, port = 52988

这是我的网络电话：

import 'dart:async';
import 'dart:convert';
import 'dart:io';

import 'package:test_flutter/constants.dart';
import 'package:test_flutter/users/models/user.dart';

class UserNetworkDatasource {
  Future<List<User>> retrieve() async {
    var httpClient = HttpClient();
    var uri = new Uri.https(baseUrl, '/users');
    var request = await httpClient.getUrl(uri);
    var response = await request.close();
    var responseJson = await response.transform(utf8.decoder).join();
    List userMap = json.decode(responseJson);

    return userMap.map((jsonUser) => User.fromJson(jsonUser));
  }
}

除此之外，还有什么事要做？我检查了Android清单，它具有Internet权限，因此应该可以

我已经用自制软件安装了 protoc，并尝试用 proto 文件生成 dart 代码。当我尝试一个简单的案例时，protoc --dart_out=. test.proto 它给了我： protoc-gen-dart: program not found or is not executable --dart_out: protoc-gen-dart: Plugin failed with status code 1. 但是protoc-gen-dart在我的道路上......

我也尝试指定路径，protoc --dart_out=. --plugin=protoc-gen-dart=~/.pub-cache/bin/protoc-gen-dart ./test.proto但同样的错误......

任何人都知道我该如何解决这个问题？

我在google play上发布了更新并看到此错误:

我不明白为什么会出现这个错误导致它在我的设备上完美运行

有人有想法吗？

这是我的Manifest.xml的一部分

<application
        android:icon="@drawable/ic_launcher" …

我有选择活动的问题,我有这个弹出窗口:

文字颜色也是白色和背景.这是我使用的代码:

    Bundle bundle = new Bundle();
    ArrayList<String> shortcutNames = new ArrayList<String>();
    shortcutNames.add(getString(R.string.group_applications));
    bundle.putStringArrayList(Intent.EXTRA_SHORTCUT_NAME, shortcutNames);

    ArrayList<ShortcutIconResource> shortcutIcons = new ArrayList<ShortcutIconResource>();
    shortcutIcons.add(ShortcutIconResource.fromContext(this,
            R.drawable.ic_launcher));
    bundle.putParcelableArrayList(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, shortcutIcons);

    Intent pickIntent = new Intent(Intent.ACTION_PICK_ACTIVITY);
    pickIntent.putExtra(Intent.EXTRA_INTENT, new Intent(Intent.ACTION_CREATE_SHORTCUT));
    pickIntent.putExtra(Intent.EXTRA_TITLE, getText(R.string.app_name));
    pickIntent.putExtras(bundle);

    startActivityForResult(pickIntent, 1);

我正在尝试在Wear模拟器上使用新的watch face API,当我扩展CanvasWatchFaceService时,onTimeTick方法从未被触发,因此时钟从未更新过.

我正在使用模拟样本并尝试删除秒针(暂时禁用计时器):

我正在尝试将Passport策略实现为sails hook,就像我可以在多个项目上共享一样.

当我尝试登录时出现此错误:

我读到我必须在config/http.js中添加一些中间件

middleware: {

    passportInit    : require('passport').initialize(),
    passportSession : require('passport').session(),

    order: [
      'startRequestTimer',

      '500'
    ]
  } …

我正在制作一个IntelliJ插件来支持nodeJS框架.我正在尝试实现自动完成功能,但不知道如何在列表顶部设置自动完成位置.首先,我有其他自动完成(mozilla等).

这是我的代码:

LookupElementBuilder
                .create(completionString)
                .withBoldness(true)
                .withCaseSensitivity(false)
                .withIcon(SailsJSIcons.SailsJS)
                .withPresentableText("\t\t\t" + item)
                .withAutoCompletionPolicy(AutoCompletionPolicy.GIVE_CHANCE_TO_OVERWRITE);

我想handleInsert可以帮助我,但无法找到如何使用它
