    <p>So I have a table named apps with 4 columns and a column named App_icon in which I convert the drawable to byte[] and store it in the colum "App_icon" as blob. I have a listview where it picks up the fields from the table as shows it. I need to also show the image at the left corner by converting back the blob to image.The code I use to retrieve the text data from the db and to display is:</p> <pre><code>mySQLiteAdapter.open(); String[] arrayColumns = new String[] { Dbhelper.KEY_PKG, Dbhelper.KEY_APP, }; int[] arrayViewIDs = new int[] { R.id.appname, R.id.pkgname }; cursor = mySQLiteAdapter.getAllFolders(); adapter = new SimpleCursorAdapter( getActivity().getApplicationContext(), R.layout.listview_items, cursor, arrayColumns, arrayViewIDs); lv.setAdapter(adapter); mySQLiteAdapter.close(); </code></pre> <p>Where KEY_PKG and KEY_APP are the other table names which is displayed in textview (appname and pkgname). Could someone provide a sample code on how to bind the image to the respective fields? Regards, Vijai</p> <p>Edit: If anyone can post how to get only the values of "App_icon" column from all the rows and store it in an array? That would be helppful</p> <p>Edit 2: Below is the method used to get the image</p> <pre><code>adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() { @Override public boolean setViewValue (View view, Cursor cursor, int columnIndex){ if (view.getId() == R.id.app_icon) { ImageView IV=(ImageView) view; Bitmap icon; BitmapFactory.Options options = new BitmapFactory.Options(); options.inPreferredConfig = Bitmap.Config.ARGB_8888; byte[] image = null; Cursor images = mySQLiteAdapter.geticon(); int rows = images.getCount(); for(int i=1;i&lt;=rows;i++){ image = mySQLiteAdapter.getIcon(i); icon = BitmapFactory.decodeByteArray(image , 0, image .length, options); Toast.makeText(getActivity(), "executes"+rows, Toast.LENGTH_SHORT).show(); IV.setImageBitmap(icon); } //IV.setBackgroundColor(Color.TRANSPARENT); return true; } return false; } }); </code></pre>

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.
