Showing a list of files in a ListView

Question

I\'m wondering how to show files from a directory in a ListView`. The files can be listed with:

File dir = new File(dirPath);
File[] filelist = dir.listFiles         


        

Answer 1

I guess you want to show the names of the files from that directory so you could try this:

File dir = new File(dirPath);
File[] filelist = dir.listFiles();
String[] theNamesOfFiles = new String[filelist.length];
for (int i = 0; i < theNamesOfFiles.length; i++) {
   theNamesOfFiles[i] = filelist[i].getName();
}

The adapter to use with the list :

new ArrayAdapter(this, android.R.layout.simple_list_item, theNamesOfFiles);

For anything more complicated than showing the names of the files you have to implement a custom adapter.
