Know if a file is a image in Java/Android

How can I check a file if it is an image?
like following:

if(file.isImage)….

If it’s not possible with standard libraries, how can I do it with the MagickImage lib?

Thanks in advance!

Answer 1

Try this code.

public class ImageFileFilter implements FileFilter {
   
    private final String[] okFileExtensions = new String[] {
        "jpg",
        "png",
        "gif",
        "jpeg"
    };


    public boolean accept(File file) {
        for (String extension: okFileExtensions) {
            if (file.getName().toLowerCase().endsWith(extension)) {
                return true;
            }
        }
        return false;
    }

}

It’ll work fine.

Use this like
new ImageFileFilter(pass file name);
