在我们的项目中快速添加需求.我们的数据库中用于保存电话号码的字段设置为仅允许10个字符.所以,如果我通过"(913)-444-5555"或其他任何东西,是否有一种快速的方法来通过某种特殊的替换函数运行字符串,我可以传递一组字符允许?
正则表达式?
Github正在进行的愚蠢问题.我有大量的更改(大小约为120MB),当我尝试推送时,会发生这种情况:
git config http.postBuffer 524288000
git config http.postBuffer 524288000
git config http.postBuffer 524288000
我已经完成了
git config http.postBuffer 524288000,所以这似乎不是问题.会是什么呢?
我有时会发现我需要重新启用警报以进行调试.当然我可以关闭标签并重新加载但是有更好的方法吗?
一种通用方法,可以返回2个参数之间的随机整数,如ruby rand(0..n).
有什么建议吗?
我有一个播放声音的按钮,它似乎在模拟器上工作得很好,但我收到这条消息:

在Angular 2文档页面上有一个使用Http服务的例子.
getHeroes (): Observable<Stuff[]> {
return this.http.get(this.url)
.map(this.extractData)
.catch(this.handleError);
}

我克隆了angular2-webpack-starter项目并自己添加了上面的代码.
我导入Observable使用
import {Observable} from 'rxjs/Observable';
Run Code Online (Sandbox Code Playgroud)
我假设属性Observable也被导入(.map有效).查看rxjs.beta-6的更改日志,没有提到任何内容catch.
我正在使用String split方法,我想拥有最后一个元素.Array的大小可以改变.
例:
String one = "Düsseldorf - Zentrum - Günnewig Uebachs"
String two = "Düsseldorf - Madison"

我想拆分上面的字符串并得到最后一项:
lastone = one.split("-")[here the last item] // <- how?
lasttwo = two.split("-")[here the last item] // <- how?

我不知道运行时数组的大小:(
API 14中引入的切换小部件默认使用holo主题进行样式设置.我想把它的风格略有不同,改变它的颜色和形状有点因为品牌的原因.怎么会这样呢?我知道它必须是可能的,因为我已经看到默认ICS和三星的touchwiz主题之间的区别

我假设我需要一些状态drawables,我在http://developer.android.com/reference/android/R.styleable.html中看到了一些样式,Switch_thumb和Switch_track看起来像我之后的样子.我只是不知道如何使用它们.
我正在使用ActionbarSherlock,如果这有所作为.当然,只有运行API v14或更高版本的设备才能使用交换机.
所以我不确定在何处/如何实现此方法以使我的服务在前台运行.目前我在另一项活动中通过以下方式开始我的服务:
Intent i = new Intent(context, myService.class);
context.startService(i);

然后在myServices的onCreate()中我尝试startForeground()......?
Notification notification = new Notification();
startForeground(1, notification);

所以是的,我有点失落,不确定如何实现这一点.
