Hi Andre
I assume that buton 3-6 are in R.layout.poput_new and not
R.layout.main, in that case you call findViewById on the activity
which does not contain those buttons. You need to call findViewById on
the dialog after you called setContentView.
Try the following:
in onCreate:
remove the following lines
button3 = (Button) findViewById(R.id.button3);
button4 = (Button) findViewById(R.id.button4);
button5 = (Button) findViewById(R.id.button5);
button6 = (Button) findViewById(R.id.button5); // typo at
this line, should probably be R.id.button6
in onCreateDialog:
add the following lined just before "button3.setOnClickListener(this);"
button3 = (Button) dialog.findViewById(R.id.button3);
button4 = (Button) dialog.findViewById(R.id.button4);
button5 = (Button) dialog.findViewById(R.id.button5);
button6 = (Button) dialog.findViewById(R.id.button6);
Cheers,
Chrigi
