    <p>Hi i want to specify a folder on the SD card to retrieve all of images in a subfolder of that folder (ex, /mnt/sdcard/Folder/SubFolder). I've this:</p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gallery); GridView gridview = (GridView) findViewById(R.id.gallery); registerForContextMenu(gridview); id = getIntent().getExtras().getString("ID"); // Set up an array of the Thumbnail Image ID column we want String[] projection = {MediaStore.Images.Thumbnails._ID}; // Create the cursor pointing to the SDCard cursor = managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, projection, // Which columns to return null, // Return all rows null, MediaStore.Images.Thumbnails.IMAGE_ID); // Get the column index of the Thumbnails Image ID columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID); </code></pre> <p>And in setAdapter of my gridview i have:</p> <pre><code>gridview.setAdapter(new BaseAdapter() { public View getView(int position, View convertView, ViewGroup parent) { ImageView picturesView; if (convertView == null) { picturesView = new ImageView(mContext); // Move cursor to current position cursor.moveToPosition(position); // Get the current value for the requested column int imageID = cursor.getInt(columnIndex); // Set the content of the image based on the provided URI picturesView.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID)); picturesView.setScaleType(ImageView.ScaleType.FIT_CENTER); picturesView.setPadding(8, 8, 8, 8); picturesView.setLayoutParams(new GridView.LayoutParams(100, 100)); } else { picturesView = (ImageView)convertView; } return picturesView; } public int getCount() { return cursor.getCount(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } }); </code></pre> <p>That's works but show me all images contained in sdcard... I've tried to set a URI path, like "content:///mnt/sdcard/folder/subfolder" but it doesen't work...How can I specify, in MediaStore managedQuery, a specific folder to scan?? </p> <p>Thank you all in advance! :)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
