Sort Files In Sdcard By Date Created

I need to sort files from sdcard folder by date created in android,i have saved files in sdcard folder using system date,can anyone help me in solving this?

Solution 1:

use a Collection.sort:

Collections.sort(list, new Comparator<File>() {
    publicintcompare(File o1, File o2) {
        long lastModifiedO1 = o1.lastModified();
        long lastModifiedO2 = o2.lastModified();

        return (lastModifiedO1 < lastModifiedO2) ? -1 : ((lastModifiedO1 > lastModifiedO2) ? 1 : 0);
    }
});

Check for typo

Solution 2:

Collection sort is the way to go as the others are suggesting.

Used this code awhile ago :

        Collections.sort(mFileList, new Comparator<File>() {
        publicintcompare(File f1, File f2) {
            return Long.valueOf(f2.lastModified()).compareTo(
                    f1.lastModified());
        }
    });

Solution 3:

You can get the Date of file one by one :

File f= newFile(filePath);
Date fileDate= newDate(f.lastModified());

And than Apply the Sorting Algorithm.

You'll achieve what you need
