dataset mode list file

[eugenelyj]

in file ORBSLAMForDatasetActivity.java:151, a line of code for (File file : dir.listFiles()) should be improved because the method listFiles makes no guarantees about the order of the files returned

Hi , you are right, I solved it by adding the follow lines in ORBSLAMForDataSetActivity.java

import java.util.Arrays;
...
...
...
...
if (!TextUtils.isEmpty(ImgPath)) {
File dir = new File(ImgPath);
File[] files = dir.listFiles();
Arrays.sort(files);
if (dir.isDirectory()) {
for (File file : files) {

...
...
...

Hope this helps!
