Question

I think I followed the Android tutorial quite closely here. I have a ListActivity which calls a showDialog(DIALOG_EXPORT); at some point. My onCreateDialog() creates a dialog, sets an xml view and then tries to do something with the elements of that dialog, but directly after findViewById() everything is null. Why?

here the code:

protected Dialog onCreateDialog(int id) {
    switch(id){
    case DIALOG_EXPORT:
        final Dialog dial = new Dialog(this);
        dial.setContentView(R.layout.export_dialog);
        dial.setTitle(R.string.dialog_export_title);
        EditText eFile = (EditText) findViewById(R.id.e_dialog_export);
        Button bOkay = (Button) findViewById(R.id.b_export_okay);
        Button bCancel = (Button) findViewById(R.id.b_export_cancel);
        <here all View elements are empty>
        ...
        return dial;

    ...
    }
}

Answer 1

You need to use dial.findViewById() instead of just findViewById()
