Showing A List Of Files In A Listview
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(); and added to the Li
Solution 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 = newString[filelist.length];
for (int i = 0; i < theNamesOfFiles.length; i++) {
theNamesOfFiles[i] = filelist[i].getName();
}
The adapter to use with the list :
newArrayAdapter<String>(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.
Solution 2:
Or you can use something like this for a sorted String
of filenames
:
FiledataDirectory= Environment.getDataDirectory();
FilefileDir=newFile(dataDirectory, "data/com.yourapp.app/files");
String[] listItems = fileDir.list();
Arrays.sort(listItems);
