title: list view header about react native
body: <p>I want to create a React Native demo that has a <code>ListView</code> header. Currently I'm just rendering a view on top of my <code>ListView</code> component:</p>
  
  <pre><code>render: function() {
      if (!this.state.loaded) {
          return this.renderLoadingView();
      }
              return (
                 &lt;View style = {styles.viewContainer}&gt;
                      &lt;Text style = {styles.title}&gt;标题：{this.state.question.content}&lt;/Text&gt;
                      &lt;Text style = {styles.year}&gt;描述：{this.state.question.description}&lt;/Text&gt;
                      &lt;ListView
                      dataSource={this.state.dataSource}
                      renderRow={this.renderMovie}
                      style={styles.listView}/&gt;
                  &lt;/View&gt;
              );
              //加载回复答案
  
  },
  
  renderLoadingView: function() {
      return (
          &lt;View style={styles.container}&gt;
              &lt;Text&gt;
                  Loading Infos...
              &lt;/Text&gt;
          &lt;/View&gt;
      );
  },
  
  renderMovie: function(movie) {
      return (
          &lt;View style={styles.container}&gt;
              &lt;View style={styles.rightContainer}&gt;
                  &lt;Text style={styles.title}&gt;{movie.content}&lt;/Text&gt;
                  &lt;Text style={styles.year}&gt;id:{movie.username}&lt;/Text&gt;
              &lt;/View&gt;
          &lt;/View&gt;
          );
      },
  });
  </code></pre>
  
  <p>I would like to render the header as a part of the <code>ListView</code> component instead. How can I do so?</p>
