我有一个TextView固定宽度如下:

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:textSize="12sp"
    tools:text="Health Department"
    android:layout_marginTop="4dp"
    android:maxLines="2"
    />

......但它看起来像:

   |Health Dep-|
   |  artment  |

......虽然我希望它是:

   |  Health  |
   |Department|

我可以使用什么XML属性来执行此操作？

我正在使用Firebase制作一个示例笔记应用程序,用户可以登录并创建简单的文本注释.我的Firebase数据结构如下:

"Project-dir":{
    "Notes":{
        "UserID":{
            "NoteKey":{
                "title":"This is note title",
                "content":"This is the note content",
                "unixTime":123456789
            },
            "NoteKey":{
                "title":"This is note title",
                "content":"This is the note content",
                "unixTime":123456789
            },
        }
    }
}

用户登录时效果很好.但是,我想添加"不登录时继续"功能.我使用push()生成唯一的用户ID,而不是使用auth UID并存储在sharedprefs中.但是,当他决定稍后登录时,如何将所有这些笔记迁移到用户的UserID(UID)？

我之前没有使用自定义样式.我想在我的应用程序上自定义EditText的样式,如下图所示.

我不是要你为我设计它.请指出我正确的方向.提前致谢!

I have a streaming server running on localhost. When I try to stream audio from it from my Android application. I'm getting static noise most of the time (The kind you get on radio). Sometimes the complete audio is static noise, sometimes a part of it, and sometimes the audio plays just fine, so I'm not sure what's going wrong.

Here's the streaming code from my android application:

new Thread(
                new Runnable() {
                    @Override
                    public void run() {
                        try { …

我正在使用Drive REST API将文件上传到Google Drive。我希望默认情况下在这些文件上启用一些默认加载项。我在这里阅读有关容器绑定脚本的信息。

但是，只有在Google Docs UI中打开文件后，才能添加容器绑定脚本。在上载时或以编程方式上载后，是否可以将脚本绑定到文件？

所以我只是尝试使用 Firebase 来更新实时数据库中活动的工具栏标签。我收到以下错误：

我正在尝试通过 eksctl 创建一个集群，使用默认选项和具有“AdministratorAccess”的 AMI 用户，我陷入了“等待 CloudFormation 堆栈”

我有以下片段

import csv

data = {}
with open('data.csv', 'rb') as csvfile:
    spamreader = csv.reader(csvfile, quotechar=None)
    count = 0
    for row in spamreader:
        data.update({row[0]:row[1]})
        count+=1
        

print(count)
print(len(data))

该文件data.csv总共包含 234611 行和 2 列。

输出是：

234611

52183

现在，读者可以阅读所有行，但无法将它们填充到data字典中。知道如何调试这个问题吗？另外，值得一提的是，csv 文件包含大量非英语字符。

我正试图通过Scrapy抓一个网站.但是,网站有时非常慢,在浏览器的第一次请求响应时需要大约15-20秒.无论如何,有时,当我尝试使用Scrapy抓取网站时,我不断收到TCP超时错误.即使网站在我的浏览器上打开正常.这是消息:

2017-09-05 17:34:41 [scrapy.downloadermiddlewares.retry] DEBUG: Gave up retrying <GET http://www.hosane.com/result/spec
ialList> (failed 16 times): TCP connection timed out: 10060: A connection attempt failed because the connected party di
d not properly respond after a period of time, or established connection failed because connected host has failed to re
spond..

我甚至已经覆盖了USER_AGENT测试设置.我不认为DOWNLOAD_TIMEOUT设置在这种情况下有效,因为它默认为180秒,而Scrapy在发出TCP超时错误之前甚至不需要20-30秒.

知道是什么导致了这个问题吗？有没有办法在Scrapy中设置TCP超时？
