android 使用了runOnUiThread 还是报错NetworkOnMainThreadException,代码如下：

Question

private EaseUser getUserInfo(final String username){ // To get instance of EaseUser, here we get it from the user list in memory // You'd better cache it if you get it from your server String curUser = EMClient.getInstance().getCurrentUser(); if(username==null||curUser==null)return null; EaseUser user = null; /* if(username.equals(curUser)) return getUserProfileManager().getCurrentUserInfo();*/ user = getContactList().get(username); if(user == null && getRobotList() != null){ user = getRobotList().get(username); } // if user is not in your contacts, set inital letter for him/her if(user == null){ user = new EaseUser(username); EaseCommonUtils.setUserInitialLetter(user); final UserBean.Account[] account = {null}; MyApplication.getInstance().getCurrentActivity().runOnUiThread(new Runnable() { public void run() { account[0] = AccountLoader.getUser(username); } }); if(account[0] !=null) { user = new EaseUser(account[0].getId()); user.setNickname(account[0].getNickname()); user.setAvatar(account[0].getAvatar()); userDao.saveContact(user); } } return user; }

Answer 1

新开一个线程使用join等待结束处理了！
Thread th = new Thread(new Runnable(){
....
});
th.join();

Answer 2

我觉得你贴出的代码没法表现问题所在，其次使用了runOnUiThread 还是报错NetworkOnMainThreadException.

本来这个错误的意思就是在UI线程访问网络报错的，你把相关逻辑放到runOnUiThread还是UI线程，一样也会报错。根本没解决问题

Answer 3

Rxjava 完美解決該問題。

Answer 4

你的getUserInfo（）是否是在UI线程调用？
