    <p>I cant find a way to save the checkbox state when using a Cursor adapter. Everything else works fine but if i click on a checkbox it is repeated when it is recycled. Ive seen examples using array adapters but because of my lack of experience im finding it hard to translate it into using a cursor adapter. Could someone give me an example of how to go about it. Any help appreciated. </p> <pre><code>private class PostImageAdapter extends CursorAdapter { private static final int s = 0; private int layout; Bitmap bm=null; private String PostNumber; TourDbAdapter mDbHelper; public PostImageAdapter (Context context, int layout, Cursor c, String[] from, int[] to, String Postid) { super(context, c); this.layout = layout; PostNumber = Postid; mDbHelper = new TourDbAdapter(context); mDbHelper.open(); } @Override public View newView(Context context, final Cursor c, ViewGroup parent) { ViewHolder holder; LayoutInflater inflater=getLayoutInflater(); View row=inflater.inflate(R.layout.image_post_row, null); holder = new ViewHolder(); holder.Description = (TextView) row.findViewById(R.id.item_desc); holder.cb = (CheckBox) row.findViewById(R.id.item_checkbox); holder.DateTaken = (TextView) row.findViewById(R.id.item_date_taken); holder.Photo = (ImageView) row.findViewById(R.id.item_thumb); row.setTag(holder); int DateCol = c.getColumnIndex(TourDbAdapter.KEY_DATE); String Date = c.getString(DateCol); int DescCol = c.getColumnIndex(TourDbAdapter.KEY_CAPTION); String Description = c.getString(DescCol); int FileNameCol = c.getColumnIndex(TourDbAdapter.KEY_FILENAME); final String FileName = c.getString(FileNameCol); int PostRowCol = c.getColumnIndex(TourDbAdapter.KEY_Post_ID); String RowID = c.getString(PostRowCol); String Path = "sdcard/Tourabout/Thumbs/" + FileName + ".jpg"; Bitmap bm = BitmapFactory.decodeFile(Path, null); holder.Photo.setImageBitmap(bm); holder.DateTaken.setText(Date); holder.Description.setText(Description); holder.cb.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CheckBox cBox = (CheckBox) v; if (cBox.isChecked()) { mDbHelper.UpdatePostImage(FileName, PostNumber); } else if (!cBox.isChecked()) { mDbHelper.UpdatePostImage(FileName, ""); } } }); return row; }; @Override public void bindView(View row, Context context, final Cursor c) { ViewHolder holder; holder = (ViewHolder) row.getTag(); int DateCol = c.getColumnIndex(TourDbAdapter.KEY_DATE); String Date = c.getString(DateCol); int DescCol = c.getColumnIndex(TourDbAdapter.KEY_CAPTION); String Description = c.getString(DescCol); int FileNameCol = c.getColumnIndex(TourDbAdapter.KEY_FILENAME); final String FileName = c.getString(FileNameCol); int PostRowCol = c.getColumnIndex(TourDbAdapter.KEY_Post_ID); String RowID = c.getString(PostRowCol); String Path = "sdcard/Tourabout/Thumbs/" + FileName + ".jpg"; Bitmap bm = BitmapFactory.decodeFile(Path, null); File x = null; holder.Photo.setImageBitmap(bm); holder.DateTaken.setText(Date); holder.Description.setText(Description); holder.cb.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CheckBox cBox = (CheckBox) v; if (cBox.isChecked()) { mDbHelper.UpdatePostImage(FileName, PostNumber); } else if (!cBox.isChecked()) { mDbHelper.UpdatePostImage(FileName, ""); } } }); } } static class ViewHolder{ TextView Description; ImageView Photo; CheckBox cb; TextView DateTaken; } } </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.
