Resizing the FastScroll Warning Dialog

Question

I want to use FastScroll for my history list and use dates for sections, but the warning dialog (which shows letters in contacts) does not stretch to fit the size of the text (I want to show its month and day).

How to change its size?

Answer 1

My decision. We will disable the built-in Fastscroll function and use this code with minor changes. The mOverlaySize variable is responsible for the size of section notifications.

            final View textEntryView = factory.inflate(R.layout.alert_dialog_text_entry, null);
