Moin zusammen,

ich kampfe seit gestern mit folgendem Problem.
Ich möchte gerne aus meiner Activity einen Dialog aufrufen in dem eine Liste angezeigt wird. Leider klappte das hinten und vorne nicht. Ich hoffe ihr habt Hilfe für mich.

Hier mal mein Layout:

loeschen_dialog.xml
Code: 
[SIZE=2][COLOR=#008080][SIZE=2][COLOR=#008080][LEFT]<?[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2][COLOR=#3f7f7f][SIZE=2][COLOR=#3f7f7f]xml[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] [/SIZE][SIZE=2][COLOR=#7f007f][SIZE=2][COLOR=#7f007f]version[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]=[/SIZE][I][SIZE=2][COLOR=#2a00ff][SIZE=2][COLOR=#2a00ff]"1.0"[/I][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] [/SIZE][SIZE=2][COLOR=#7f007f][SIZE=2][COLOR=#7f007f]encoding[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]=[/SIZE][I][SIZE=2][COLOR=#2a00ff][SIZE=2][COLOR=#2a00ff]"utf-8"[/I][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2][COLOR=#008080][SIZE=2][COLOR=#008080]?>

Hier mein Dialog:

}

} [/LEFT]
}
[/SIZE]

In meiner Activity mache ich folgendes:

Code: 
[SIZE=2][LEFT]LoeschenDialog loeschenDialog = [/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] LoeschenDialog([/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]this[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]);
ListView list = (ListView) loeschenDialog.findViewById(R.layout.[/SIZE][I][SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]loeschen_dialog[/I][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]);
[U]ArrayAdapter[/U] modeAdapter = [/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]new[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] [U]ArrayAdapter[/U]([/SIZE][B][SIZE=2][COLOR=#7f0055][SIZE=2][COLOR=#7f0055]this[/B][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2], android.R.layout.[/SIZE][I][SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]simple_list_item_1[/I][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2], R.array.[/SIZE][I][SIZE=2][COLOR=#0000c0][SIZE=2][COLOR=#0000c0]myArray[/I][/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2]); [/LEFT]
list.setAdapter(modeAdapter); 
[/SIZE]

Die zurückgegebene Liste wird wohl nicht gefunden, sie ist immer null.

Was mach ich falsch?

Danke und Gruß
Spike
 
hmm

das geht so nunmal einfach nicht.

wenn du findviewbyid machst, dann musst die id der listview angeben. du gibst die id des löschen_dialogs an

btw: es ist üblich englisch zu verwenden. vor allem schonmal wegen der umlaute, wie du sicher bemerkt hast.
