我不想同时抓取并被阻止.我想每秒发送一个请求.

我想在textview上放一个圆圈背景.渲染时圆圈变成椭圆形.

我的布局XML:

    <TextView
        android:id="@+id/amount_key"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_marginRight="2dp"
        android:gravity="center"
        android:background="@drawable/circle"
        android:layout_marginLeft="20dp"
        android:text="3\ndays"
        android:padding="20dp"
        android:textColor="#ffffff"
        android:textStyle="bold"
        android:textSize="25dp" />


</LinearLayout>

我的圈子背景:

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval">

            <solid 
               android:color="#79bfea"/>
</shape>

有些网站暂时出现404错误.但我粘贴在浏览器上它可以工作.如何告诉scrapy重试404状态代码链接5次.

我已经下载了250G的freebase数据转储.我不想在大数据上迭代我的开发.我想提取一小部分数据(可能是一个小域或一些10个人及其信息).这个小子集将使我的迭代更快更容易.

分区freebase数据的最佳方法是什么？是否有Google/Freebase提供的子集下载？

我使用以下活动从我的应用中启动了YouTube视频.启动活动后,将播放YouTube视频.但是当我改变屏幕的方向时,视频没有恢复,而是从头开始.这是什么问题？

public class YTPlayActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {


       static private String yt_sk;
       static private final String DEVELOPER_KEY = "my-api-key";

       @Override

       protected void onCreate(Bundle savedInstanceState) {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.yt_player);
              Bundle extras = getIntent().getExtras();
             yt_sk = extras.getString("yt_sk");

              YouTubePlayerView youTubeView = (YouTubePlayerView)
findViewById(R.id.youtube_view);

           youTubeView.initialize(DEVELOPER_KEY, this);

          }

         @Override

         public void onInitializationFailure(Provider provider,
YouTubeInitializationResult error) {

                Toast.makeText(this, "Oh no! "+error.toString(),
Toast.LENGTH_LONG).show();

       }

我想抓取一个只支持发布数据的网站.我想在所有请求中的post数据中发送查询参数.怎么做到这一点？

是否有口袋狮身人面像或cmu狮身人面像的命令行实用程序将.wav文件转换为文本？

pocketsphinx_continuous -hmm -lm -dict会做的.但我不想一次又一次地说同一句话.
