    <p>I'm developing an app that shows the user a whole bunch of flash cards using a ViewPager. My problem is as follows - I have a custom PagerAdapter I made to handle cursors and get a whole bunch of data from my database and put it into a view. I want to add an option to delete a card but I'm not sure how to go about doing it. Here's my PagerAdapter code. Not too sure where to go from here.</p> <pre><code>public class CardCursorPagerAdapter extends PagerAdapter { private Cursor cursor; private LayoutInflater inflater; public CardCursorPagerAdapter(Context context, Cursor cursor){ this.cursor = cursor; this.inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public void swapCursor(Cursor cursor){ this.cursor = cursor; } @Override public void destroyItem(View view, int position, Object object) { ((ViewPager) view).removeView((LinearLayout) object); } @Override public int getCount() { if (cursor == null) { return 0; } else { return 1000; } } @Override public Object instantiateItem(View view, int position) { LinearLayout layout; int position2 = position; if (position == 0){ layout = (LinearLayout) inflater.inflate(R.layout.activity_slide_info, null); } else { position2++; position2 = position2 % cursor.getCount(); cursor.moveToPosition(position2); layout = (LinearLayout) inflater.inflate(R.layout.activity_card, null); TextView cardTitle = (TextView) layout.findViewById(R.id.card_title); TextView cardExample = (TextView) layout.findViewById(R.id.card_example); TextView cardDefinition = (TextView) layout.findViewById(R.id.card_definition); cardTitle.setText(cursor.getString(cursor.getColumnIndex(FlashCardTable.COLUMN_TITLE))); cardExample.setText(cursor.getString(cursor.getColumnIndex(FlashCardTable.COLUMN_SENTENCE))); cardDefinition.setText(cursor.getString(cursor.getColumnIndex(FlashCardTable.COLUMN_DEFINITION))); } ((ViewPager) view).addView(layout); return layout; } @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == arg1; } } </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.
