what does the code that goes with this statement look like?

“Now the calling activity needs to provide the object of the class that implements the MyDialogListener which will gets called on ok or cancel button clicks.”

if i have a text view in my original activity how do i connect it to the listener from my dialog to get the information from the dialog.

Hi,
I want to update the dialog before it is getting shown,I used the showdialog method and to create the dialog I use this:

protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_LIST:

return new AlertDialog.Builder(calendar.this).setTitle(“Events”).setItems(dialog_items_Event, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {

viewcalendar();
}
})
.create();

}

return null;}

but every time I click in the item I get the same dialog ,my be I use
onPrepareDialog() method but where and how I use it ? please I need answer

Thank you Mayur,
But I wanted it to set in onCreateDialog().
protected Dialog onCreateDialog(int id) {
progress = new ProgressDialog(this);
switch(id){
case PROGRESS_START :
progress.setContentView(R.layout.progess);
textview = (TextView)findViewById(R.id.text);
textview.setText(“this is custom progressdialog”);
return progress;
}
return null;

}
and i called showDialog in onCreate method
but it is showing NULLPOINTEREXCEPTION
i think it is finding the view
so do you have any suggestion/example
thank you once again.

Hi Amol,
if you want to change the color of progressdialog ,i have one solution on it,
used setContentView method to change the background of progressdialog,
here is my project link-http://www.androidcompetencycenter.com/wp-content/uploads/2010/05/ProgressDialog.zip

Hello,

Thanks for the post, its a great guide.

I am trying to implement the code, which worked fine till I got to adding the code:

MyDialogListener listener

Once added, how do you call the dialog from the activity, and how do you receive the entry in that activity? If there any chance of getting the code you would use in the calling activity?

Thanks!

@Nils Thorell
Hi Nils,

The layout is given in the above code

Save the complete layout xml code given in the tutorial above as mydialog.xml in res/layout location in your android application.

If this doesn’t solve your problem,then post the exception here
(You can see the exception in the logcat in DDMS view).

The program crashes on
setContentView(R.layout.mydialog);

How can I define ‘mydialog’ in the layout?

Thanks, the best android dialog example I have found. Illustrative, useful, thorough and easy. Only note: the OnClickListener ‘implemented’ above is imported from View not DialogInterface.
