用TextView去显示html代码，效果不是很好：

TextView lblContent = findView(R.id.lblContent);
			lblContent.setText(Html.fromHtml(bean.getContent(),
					imageUtil.htmlImageTag(ImageUtil.HTML_TYPE_NET, this),
					new HtmlTagHandler(this)));
			lblContent.setClickable(true);
			lblContent.setMovementMethod(LinkMovementMethod.getInstance());
			lblContent.setVisibility(View.VISIBLE);

ImageUtil的代码：
/**
	 * 解析html图片标签的适配器
	 * 
	 * @param sourceType
	 *            图片来源的类型
	 * @param activity
	 *            容器
	 * @return
	 */
	public Html.ImageGetter htmlImageTag(final int sourceType,
			final AbstractActivity activity) {
		return new Html.ImageGetter() {
			public Drawable getDrawable(final String url) {
				Drawable drawable = null;
				try {
					switch (sourceType) {
					case HTML_TYPE_NET:
						FutureTask<Drawable> task = new FutureTask<Drawable>(
								new Callable<Drawable>() {
									public Drawable call() throws Exception {
										try {
											return new BitmapDrawable(activity
													.getBitmapByUrl(url));
										} catch (Exception e) {
											return new BitmapDrawable(
													activity.resBitmap(R.drawable.def_photo));
										}
									}
								});
						new Thread(task).start();
						drawable = task.get((long) Domain.SHORT_REQUEST_TIME,
								TimeUnit.MILLISECONDS);
						break;
					case HTML_TYPE_RES:
						drawable = TckApp.get().getResources()
								.getDrawable(Integer.parseInt(url));
						break;
					case HTML_TYPE_LOCAL:
						drawable = Drawable.createFromPath(url);
						break;
					}
				} catch (Exception e) {
					Log.e(Domain.TAG_NAME, "解析html图片标签的适配器");
				}
				if (null != drawable) {
					drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),
							drawable.getIntrinsicHeight());
				}
				return drawable;
			};
		};
	}

换成WebView，效果会好很多

WebView wbvContent = findView(R.id.wbvContent);
			BrowserUtil.get(wbvContent, null, null, true);
			wbvContent.loadDataWithBaseURL("file://", bean.getContent(),
					BrowserUtil.MIME_TYPE_HTML, HTTP.UTF_8,
					BrowserUtil.ABOUT_BLANK);
			wbvContent.setVisibility(View.VISIBLE);

Html.fromHtml(htmlString, imageGetter, null) 我用起来就没没问题的啊 http://www.cnblogs.com/mxgsa/archive/2012/12/14/2816775.html 我就是按照这样来做的

TextView content = (TextView) findViewById(R.id.content); String text ="显示网络图片<img src='http://images.csdn.net/20140327/QQ%E6%88%AA%E5%9B%BE20140327133248.png'>" content.setText(text ); ------------ 就这样啊。
