How to split the string a android?

Question

I am working on android application. I am getting the image from gallery. Also I am getting the image path from gallery. Now my requirement is I want to get only the image name with the extension . How can I do that? Please help me.

String imgpath = "/mnt/sdcard/joke.png";

The image extension can be anything joke.png or joke.jpeg. I need to get the image name with extension finally.

i.e I want to split the above string and get only joke.png.

How can I achieve that? Please help me in this regard.

String imgpath = "/mnt/sdcard/joke.png"; String result = imgpath.substring(imgpath.lastIndexOf("/") + 1); System.out.println("Image name " + result);

Output :-

Image name joke.png

You can do that in Android like in any Java program:

String[] parts = imagepath.split("/"); String result = parts[parts.length-1];

String s[] = imgpath.split("/"); String result = s[s.length-1];

String imgName = imgpath.substring((imgpath.lastIndexOf("/") + 1), imgpath.length());

You can get this with Regex too, if that is the hammer you have in your hands:

String fileName = null; Pattern pattern = Pattern.compile("(^|.*/)([^/]*)$"); Matcher m = pattern.getMatcher(filenameWithPath); if(matcher.matches()) { fileName = matcher.group(2); }

But don't be tempted to do this. This is less readable, and probably even slower than the other methods.
