2.5 MyURLSpan.java：定义一个可点击的Span，点击超链接时通过
浏览器打开改网页/文件。
public class MyURLSpan extends ClickableSpan {
private Context context = null;
private String mUrl = null;;
public MyURLSpan(Context context,String url) {
this.context = context;
this.mUrl = url;
}
@Override
public void onClick(View widget) {
if (URLUtil.isNetworkUrl(mUrl)) {
XXXUtils.openMyWebBrowser(this.context,
this.context.getResources().getString(R.string.newstext_hyperlink),
this.mUrl);
}
}
}
3 使用简单，可以在xml文件中引用，也可以动态创建视图。
3.1 在xml中引用

3.2 java代码，设置显示内容
itvFreeContent = (MyImageTextView) this.findViewById(R.id.XXX_Content);
itvFreeContent.setSupportMovementMethod(true);
//itvFreeContent.setShowImageIndex(true);
itvFreeContent.setText(Html.fromHtml(formatContent(content)));
当然这里还需要加入图片异步下载完成后的代码，如：
private void initHandler() {
this.mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case KLoadImageOver:
itvFreeContent.setPic(msg.getData().getString("fileURL"));
break;
default:
break;
}
}
};
}
实际效果图（截取部分）：
4 第二种方式需要扩展的是，如果显示的内容有超链接，且超链接时中的显示对象是图片，那么需要给图片增加点击事件，点击的跳转参照MyURLSpan.onClick。
关于图片的下载，这里推荐一个第三方库Android-Universal-Image-Loader。
