Moin,
ich habe eine Registration + Login erstellt mit Hilfe einer SQLite Datenbank.
Hat soweit auch geklappt, habe einen Benutzer erstellen können (Username + Password) und kann mich auch damit einloggen.
Aber wenn ich jetzt einen 2. Benutzer erstellen/registrieren möchte, dann geht das nicht.. Liegt es vll. am Speicherplatz oder sowas in der Art?!
Ich hänge hier mal die Codes an:

Ich hoffe irgendjemand kann mir da ein Tipp geben :drool:
Grüß'chen
 
ich würde mal sagen das du da Probleme mit deinen AlertDialog hast

ich denke mal das es an dem hier liegt:

Code: 
Intent myIntent = [B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/COLOR][/SIZE][/COLOR][/SIZE][/B][SIZE=2] Intent(( (View) dialog).getContext(), IeP.[/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]class[/COLOR][/SIZE][/COLOR][/SIZE][/B][SIZE=2]); 
startActivity(myIntent);
[/SIZE]

und zu dem Warning in deinem LogCat (Zeile 1) hab ich das hier gefunden: android - "No keyboard for id 0" - what does it mean? - Stack Overflow

Sprich du musst dir da keine Gedanken machen :)
 
Ich möchte mir jetzt nicht den ganzen Code anschauen.
Code: 
at de.projekt.irgendeinprojekt.RegisterActivity$1.onClick(RegisterActivity.java:82)
Was steht also in der RegisterActivity Zeile 82?

Gruß
 
Hm, somit wäre die Zeile
Code: 
[SIZE=2]
Intent myIntent = [/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] Intent(( (View) dialog).getContext(), IeP.[/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]class[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]);
[/SIZE]
schuld.
Aber das Doofe ist, das ganze muss ja da stehen bleiben, weil ich sonst die LoginActivity(IeP.class) durch den Dialog nicht öffnen kann.
 
versuch mal das anstatt so:

Code: 
Intent myIntent = [B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/COLOR][/SIZE][/COLOR][/SIZE][/B][SIZE=2] Intent(( (View) dialog).getContext(), IeP.[/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]class[/COLOR][/SIZE][/COLOR][/SIZE][/B][SIZE=2]);
[/SIZE]

lieber so:

Code: 
Intent myIntent = [B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/COLOR][/SIZE][/COLOR][/SIZE][/B][SIZE=2] Intent([COLOR=#0000c0]context[/COLOR], IeP.[/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]class[/COLOR][/SIZE][/COLOR][/SIZE][/B][SIZE=2]);
[/SIZE]

auf jeden Fall nicht der Context vom Dialog, du brauchst dem von deiner RegisterActivity

Zum Vergrößern anklicken....

Habe es im selben Augenblick wie dein Post selbst gelöst.

Code: 
[SIZE=2]
[LEFT]Intent myIntent = [/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] Intent([/SIZE][SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]mContext[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2], IeP.[/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]class[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]); 
myIntent.setFlags(Intent.[/SIZE][I][SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]FLAG_ACTIVITY_CLEAR_TOP[/I][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]);[/LEFT]
[/SIZE][SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]mContext[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2].startActivity(myIntent);
[/SIZE]

So klappt alles wunderbar. Trotzdem danke für die Hilfe!
