因为一个界面上面的内容太多，下面ListView查看不到，想在外面

加上scrollView，可是还是不行，结果没办法，用linearlayout代替

。对于具体要求，自己慢慢完善，这个相当于一个框架形式:

自己修改的地方：

public class AdapterForLinearLayout extends BaseAdapter {

	private LayoutInflater mInflater;
	private List<Map<String, Object>> data;
	public int count;
	private Context context;


	public AdapterForLinearLayout(Context context) {
		super();
		this.context = context;
		this.mInflater = (LayoutInflater) context
				.getSystemService("layout_inflater");
		this.data = new ArrayList<Map<String, Object>>();
		count = data.size();
	}

	public final class ListItemView {// 自定义控件集合
		public TextView thread_number;
		public TextView thread_author;
		public TextView thread_time;
		public TextView thread_text;
	}

	public int getCount() {
		return data.size();
	}

	public Object getItem(int position) {
		return data.get(position);
	}

	public long getItemId(int position) {
		return position;
	}
	
	public void addList(List<Map<String, Object>> mList) {
		data.addAll(mList);
	}

	public void remove(List<Map<String, Object>> mList) {
		data.remove(mList);
	}

	public View getView(int position, View convertView, ViewGroup arg2) {
	
		ListItemView listItemView = null;
		if (convertView == null) {
			listItemView = new ListItemView();
			convertView = LayoutInflater.from(context).inflate(
					R.layout.forum_threaddetails_item, null);
			listItemView.thread_number = (TextView) convertView
					.findViewById(R.id.thread_number);
			listItemView.thread_author = (TextView) convertView
					.findViewById(R.id.thread_author);
			listItemView.thread_time = (TextView) convertView
					.findViewById(R.id.thread_time);
			listItemView.thread_text = (TextView) convertView
					.findViewById(R.id.thread_text);
			convertView.setTag(listItemView);
		} else {
			listItemView = (ListItemView) convertView.getTag();
		}
		listItemView.thread_number.setText((String) data.get(position).get(
				"thread_number"));
		listItemView.thread_author.setText((String) data.get(position).get(
				"thread_author"));
		listItemView.thread_time.setText((String) data.get(position).get(
				"thread_time"));
		listItemView.thread_text.setText((String) data.get(position).get(
				"thread_text"));
		return convertView;
	}

	/**
	 * 绑定视图
	 * 
	 * @param view
	 * @param item
	 * @param from
	 */
	private void bindView(View view, Map<String, Object> item, String from) {
		Object data = item.get(from);
		if (view instanceof TextView) {
			((TextView) view).setText(data == null ? "" : data.toString());
		}
	}

}

/**
	 * 绑定布局
	 */
	public void bindLinearLayout() {
		int count = adapter.getCount();
		for (int i = 0; i < count; i++) {
			View v = adapter.getView(i, null, null);
			v.setOnClickListener(this.onClickListener);
			if (i == count - 1) {
				LinearLayout ly = (LinearLayout) v;
				ly.removeViewAt(2);
			}
			addView(v, common.mNUM);
			common.mNUM++;
		}
	}

private ArrayList<Map<String, Object>> initValues() {
		list_buffer = CommonUtil.parseXml2(buffer, "r");
		adapter = new AdapterForLinearLayout(this);
		ArrayList<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
		int total = common.CURRENTPAGE * common.PAGESIZE;
		if (list_buffer.size() <= 0) {
			// return;
			Toast.makeText(ThreadDetailsActivity.this, "没有回复内容",
					Toast.LENGTH_SHORT).show();
		} else {
			if (total < list_buffer.size()) {
				addPageMore();
			}
			for (int i = (common.CURRENTPAGE - 1) * common.PAGESIZE; i < total; i++) {
				if (total >= list_buffer.size()) {
					total = list_buffer.size();
				}
				String mContent = (String) list_buffer.elementAt(i);
				detailAuthor = CommonUtil.parseXml(mContent, "a");
				Content = CommonUtil.parseXml(mContent, "c");
				floor = CommonUtil.parseXml(mContent, "l");
				Time = CommonUtil.parseXml(mContent, "rt");

				Map<String, Object> win = new HashMap<String, Object>();
				win.put("thread_number", floor + "楼");
				win.put("thread_author", detailAuthor);
				win.put("thread_time", Time);
				win.put("thread_text", Content);
				list.add(win);
			}
		}
		return list;
	}

然后调入到Handler handler = new Handler() {
		public void handleMessage(Message msg) {
//具体....
}中。

我自己做的一个是论坛帖子详情，以及回帖，跟帖，而且是带分页效果的：

 下面这个压缩包项目只是相对应的框架形式，数据是死的

最近需要用到jquery文件上传插件，发现plupload这东西挺好的，奈何后台代码是php，tomcat得配置php才能跑起来，于是稍微研究了下，改成了java代码

plupload的特色是

1、可以配置chunk，将一个大文件分成许多小文件上传，后台通过php合并成大文件，这里通过相应的java代码

2、实际上传的文件名是经过生成唯一的uuid，通过参数name传递到后台

3、上传文件的过程是先上传临时命名为uuid的临时文件，上传成功后会自动生成几个input标签，对应上传之后的临时文件的文件名，之后通过另一个action调用uploadFinish对临时文件进行重命名 操作或者其他操作

这个java代码是基于 Struts2的，不是servlet，反正都是类似的 在这基础上也容易改

public class UploadAction extends ActionSupport {


       private static final int BUFFER_SIZE = 2 * 1024;


	private File upload;
        private String name;  //plupload上传文件的临时文件名 uuid.文件后缀
	private String uploadFileName;
	private String uploadContentType;
	private int chunk;
	private int chunks;

// 。。。一堆getter setter自己生成



        private void copy(File src, File dst) {
		InputStream in = null;
		OutputStream out = null;
		try {
			if (dst.exists()) {
				out = new BufferedOutputStream(new FileOutputStream(dst, true),
						BUFFER_SIZE);  //plupload 配置了chunk的时候新上传的文件appand到文件末尾
			} else {
				out = new BufferedOutputStream(new FileOutputStream(dst),
						BUFFER_SIZE);
			}
			in = new BufferedInputStream(new FileInputStream(src), BUFFER_SIZE);

			byte[] buffer = new byte[BUFFER_SIZE];
			int len = 0;
			while ((len = in.read(buffer)) > 0) {
				out.write(buffer, 0, len);
			}
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			if (null != in) {
				try {
					in.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
			if (null != out) {
				try {
					out.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}



        public String upload() throws Exception {

		String dstPath = ServletActionContext.getServletContext().getRealPath("\\tmp")
				+ "\\" + this.getName();  // 保存目录可以自己配置 或者定义变量自行配置
		File dstFile = new File(dstPath);

		// 文件已存在删除旧文件（上传了同名的文件）
		if (chunk == 0 && dstFile.exists()) {
			dstFile.delete();
			dstFile = new File(dstPath);
		}

		copy(this.upload, dstFile);

               //System.out.println(uploadFileName + " " + uploadContentType + " "
				+ chunk + " " + chunks);
		if (chunk == chunks - 1) {
			// 一个完整的文件上传完成
		}

		return SUCCESS;
	}

	public String uploadFinish() {
		String dstPath = ServletActionContext.getServletContext().getRealPath("\\tmp");

		HttpServletRequest request = ServletActionContext.getRequest();
		
		int count = Integer.parseInt(request.getParameter("uploader_count"));
		for (int i = 0; i < count; i++) {
			uploadFileName = request.getParameter("uploader_" + i + "_name");
			name = request.getParameter("uploader_" + i + "_tmpname");
			System.out.println(uploadFileName + " " + name);
			try {

//对已经上传成功的临时文件进行操作		
                        } catch(Exception e) {
				
			}
		}
		return SUCCESS;
	}

}

补充：

从项目里抽取出了文件上传的代码，单独一个eclipse上可以跑的例子，上传上来了(注意build path里的jre路径)
