Answer 1

Create DataBase helper class like this..

On Capturing the image insert the image by converting into bytes:

Imagehelper help=new Imagehelper(this);

    if (requestCode == CAMERA_REQUEST) {  
                        Bitmap photo = (Bitmap) data.getExtras().get("data");   
                        imageView.setImageBitmap(photo);
                        ByteArrayOutputStream stream = new ByteArrayOutputStream();
                        photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
                        byte[] byteArray = stream.toByteArray();

                        help.insert(byteArray);
    }

To retrieve Form the Database:

Imagehelper help=new Imagehelper(this);

       Cursor c= help.getAll();
       int i=0;
       if(c.getCount()>0)
       {  
           Bitmap[]  array=new Bitmap[c.getCount()];
           c.moveToFirst();
           while(c.isAfterLast()==false)
           {

               byte[] bytes=c.getBlob(c.getColumnIndex("imageblob"));

            array[i]=BitmapFactory.decodeByteArray(bytes, 0, 0);
            c.moveToNext();
            i++;
            }
           Log.e("Bitmap length",""+array.length);
       }

Pass this Bitmap array to ListView
