在toast和任何其他UI更改中尝试此操作
public void login(int id)
{
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "OK LOGGED IN",Toast.LENGTH_LONG).show();
}
});
}
尝试RunnuiThread中的toast我应该在哪个函数中toast？你是说doInBackground？我想你的错误不是因为408，而是因为UI线程，所以请尝试RunnuiThread中的activity.login（id）。很抱歉，我在这里有点不知所措，该activity.login（id）放在哪里？我是个新手，那么UI线程是什么呢？我也是android新手，请检查我的答案，这可能会对你有所帮助，这只是猜测。我试过并在我的logcat 10-06 02:29:01.919:I/Choreographer（1956）：跳过了58帧！应用程序可能在其主线程上做了太多工作。10-06 02:29:02.279:I/编舞（1956）：跳过84帧！应用程序可能在其主线程上做了太多工作。最后的结果仍然指向错误函数OK我做了您所做的更改，并在（（line=rd.readLine（））！=null）{result=line.trim（）；Log.w（“SENCIDE RSULT”，result）；}确认它打印了正确的结果。所以现在是通过的问题，我想我也注意到响应代码实际上是200而不是2022。当你说UI相关的代码时，我非常困惑。为了和大家分享，我现在做了一些修改，如果（headerCode==200）{activity.login（id）；}，它工作得非常好。所以问题在于响应代码。无需运行runOnUIThread
