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();
