Question

I have a edit text field in which reason can be entered. But if a person enters all spaces in the reason how can I detect it. Is there a way when a person enters all spaces or nothing , i have to save the text the text as a simple “hiphen”. My main question is how to trim those spaces coming at the end.

Answer 1

The method trim() in String trims excess spaces on Strings.

String str = "Hello  ";
String str2 = str.trim();

str2 would equal “Hello”.

As for detecting when a person enters all spaces – check the str.length() after you’ve ran str.trim().
