6.后台任务封装

	private void doOk() {
 String text = etName.getText().toString().trim();
 if (TextUtils.isEmpty(text)) {
 ToastUtil.show(getActivity(), "名字不能为空");
 return;
 }
 // 数据更新
		account.setName(text);
		dao.updateAccount(account);
 String url = "http://192.168.1.101:8080/ChatServer/user/name";
 Map<String, String> headers = new HashMap<String, String>();
		headers.put("account", account.getAccount());
		headers.put("token", account.getToken());
 Map<String, String> parameters = new HashMap<String, String>();
		parameters.put("name", text);
 // 1. 将请求加入到后台任务
 // 1) 封装
 NetTask request = new NetTask();
		request.setUrl(url);
		request.setMethod(0);
		request.setHeaders(headers);
		request.setParameters(parameters);
 // 2) 序列化
 String outPath = DirUtil.getTaskDir(getActivity()) + "/"
 + System.currentTimeMillis();
 try {
 SerializableUtil.write(request, outPath);
 } catch (Exception e) {
			e.printStackTrace();
 }
 // 3) 存储到数据库记录
 BackTask task = new BackTask();
		task.setOwner(account.getAccount());
		task.setPath(outPath);
		task.setState(0);
 new BackTaskDao(getActivity()).addTask(task);
 // 开启服务
		getActivity().startService(
 new Intent(getActivity(), BackgroundService.class));
 // 2. 页面跳转
 Intent intent = new Intent(getActivity(), HomeActivity.class);
		startActivity(intent);
		getActivity().finish();
