Android Button to show downloaded files

Here's my scenario

  2. User presses the menu button to go to the downloaded files located in SD Card

Please show me how to implement a button to link to SD CARD location

below are my codes. 

File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/downloaded/stuffs");
dir.mkdirs();

File file = new File(dir, fileName);

FileOutputStream f = new FileOutputStream(file);

Your button handler 

myButton.setOnClickListener(new OnClickListener() {

public void onClick(View v) {
    Intent intent = new Intent( this, FileList.class);
    startActivity(intent);

 }
});

And to show all files in that directory define class FileList like this

public class FileList extends ListActivity 
{
    private File file;
    private List<String> myList;

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

        myList = new ArrayList<String>();   

        File sdCard = Environment.getExternalStorageDirectory();
        File dir = new File (sdCard.getAbsolutePath() + "/downloaded/stuffs");

        File list[] = dir.listFiles();

        for( int i=0; i< list.length; i++)
        {
            myList.add( list[i].getName() );
        }

        setListAdapter(new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, myList ));

    }
}
