Question

I have a problem with some functionality. I have in Action Bar TextView with text. When text is to long I use setEllipsize(TruncateAt.End) and everything work ok. But I want add functionality when user click on this TextView in this place show table with all text. How I can do that. Use dialog or there is any other way to show small field with all text. This text never was longer than 30 chars.

Answer 1

For example

1) you can popup your own custom dialog with whole text,

2) you can create a new activity with transparent BG with containing text,

3) you can expand you bar and show the whole text,

4) you can implement runnable\scrollable string in your header: Scrolling Textview in android
