onCreateDialog and dynamic dialogs (Android)

I have a little problem. In my program I defined

protected Dialog onCreateDialog(int id) {
    if (id == CONTEXT_MENU_ID) {
        return createMyDialog();
    }
    return super.onCreateDialog(id);
}

and then show the dialog calling 

showDialog(CONTEXT_MENU_ID)

My problem is that sometimes I want to change the texts of the Dialog dynamically between executions. But with that method the Dialog is never recreated. How can I make the createMyDialog() to be called before showing the Dialog?

Thanks

If you want to change dialog settings (text, etc.) you need to do it in onPrepareDialogMethod it will be called each time you call showDialog method

This might be worth a try. I haven't tested it out. To the dialog if you set the textview as its content, then you can set an id to it.

TextView text = new TextView(this);
ViewGroup.LayoutParams vp = new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT,
        LayoutParams.WRAP_CONTENT);
text.setLayoutParams(vp);
text.setText("HI");
text.setId(1005);    
dialog.setContentView(text);

So the next time when you try to update the textview, you might be able to access it using the id.

((TextView)dialog.getWindow().getDecorView().findViewById(1005))
        .setText("New Text");
