Android TimePicker SetTitle UIThread Issues -

Android TimePicker SetTitle UIThread Issues -

i understand calledfromwrongthreadexception exception means, cannot comprehend how code have written isn't executing on uithread in situation.

in main activity create handler.

private final handler handler = new apphandler(this);

in oncreatedialog method of activity, using constructor suggested android examples of timepicker dialogues. since getting calledfromwrongthreadexception in way didn't understand , wasn't reproducible on devices or emulator, tried pass reference of activity in create dialogue constructor.

so code create dialog looks this.

@override protected dialog oncreatedialog(int id) { final calendar c = calendar.getinstance(); switch (id) { case time_dialog_id: homecoming new timepickerdialog(this, this, gethandler(), mtimesetlistener, c.get(calendar.hour_of_day), 0, false);

the first instance of "this" gets used context dialog, sec instance gets stored off activity.

the dialog android sample code have been attempting prepare threading problems i'm seeing.

then within of dialog having threading issues. utilize main activity , seek utilize handler execute settitle command runnable.

mainactivity.gethandler().post(new runnable() { public void run() { settitle(mdateformat.format(mcalendar.gettime())); } });

edit: changing code effort run on ui thread using method on main activity instead of handler produces same results.

mainactivity.runonuithread(new runnable() { public void run() { settitle(mdateformat.format(mcalendar.gettime())); } });

here's re-create of stacktrace:

android.view.viewroot$calledfromwrongthreadexception: original thread created view hierarchy can touch views. @ android.view.viewroot.checkthread(viewroot.java:3214) @ android.view.viewroot.invalidatechild(viewroot.java:681) @ android.view.viewroot.invalidatechildinparent(viewroot.java:707) @ android.view.viewgroup.invalidatechild(viewgroup.java:2511) @ android.view.view.invalidate(view.java:5418) @ android.widget.textview.checkforrelayout(textview.java:5750) @ android.widget.textview.settext(textview.java:2866) @ android.widget.textview.settext(textview.java:2727) @ android.widget.textview.settext(textview.java:2696) @ com.android.internal.app.alertcontroller.settitle(alertcontroller.java:222) @ android.app.alertdialog.settitle(alertdialog.java:100) @ com.testapp.timepickerdialog$1.run(timepickerdialog.java:159) @ android.os.handler.handlecallback(handler.java:587) @ android.os.handler.dispatchmessage(handler.java:92) @ android.os.looper.loop(looper.java:130) @ android.app.activitythread.main(activitythread.java:3691) @ java.lang.reflect.method.invokenative(native method) @ java.lang.reflect.method.invoke(method.java:507) @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:907) @ com.android.internal.os.zygoteinit.main(zygoteinit.java:665) @ dalvik.system.nativestart.main(native method

also note utilize same handler on app execute things on ui thread.

any suggestions on other approaches might seek or tips debug appreciated.

thanks!

use

runonuithread(new runnable() { @override public void run() { //ui codes }}); edit

i think u should deal dialogclass innerclass mainactivity,then phone call runonuithread

hope may help you

android

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
