Getting Media Title from a File

问题

I used import java.io.File; to import all music files from my sdcard, Now i want the Title's of the files using Mediastore but how do I do that? This is the code I Use now.

public class ListFiles extends ListActivity {
 private List<String> directoryEntries = new ArrayList<String>();


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent i = getIntent();
    File directory = new File(i.getStringExtra("directory"));

    if (directory.isDirectory()){
        File[] files = directory.listFiles();

        Arrays.sort(files, new Comparator<File>(){
            public int compare(File f1, File f2) {
                return -Long.valueOf(f1.lastModified()).compareTo(f2.lastModified());
            }
        });

        this.directoryEntries.clear();
        for (File file : files) {
            this.directoryEntries.add(file.getName());  
        }

        ArrayAdapter<String> directoryList = new ArrayAdapter<String>(this,R.layout.file_row, this.directoryEntries);
    this.setListAdapter(directoryList);
    }

}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
File clickedFile = new File(this.directoryEntries.get(position));
Intent i = getIntent();
i.putExtra("clickedFile", clickedFile.toString());
setResult(RESULT_OK, i);
finish();
}

}

Thanks.

I have done that for Video files using MediaStore : Class Overview - The Media provider contains meta data for all available media on both internal and external storage devices.

You can refer these two example to understand the use of MediaStore List Video and List Audio
