    <p>I was wondering how to set a number starting from 1 to n for my listview items. The column is not included in my sqllite database. </p> <p>I would like to use a custom simple cursor adapter that has a textview called labelNumber and set the number to 1 on the first call to newView and bindview and increment the value after each call. </p> <p>Is this the right approach or is there a better way. Obviously this is to help with the navigation of the list view to know your current position?</p> <p><strong>Update- code is working check comments below</strong></p> <pre><code>public class ProgressAdapter extends SimpleCursorAdapter { private Context context; private int layout; private ViewHolder viewHolder; // create an integer to use as a number holder private int n; static class ViewHolder { public TextView number; public TextView setsText; public TextView repsText; public TextView weightText; public TextView completeText; public ImageView mgImage; } public ProgressAdapter(Activity context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout; } @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { Cursor c = getCursor(); viewHolder = new ViewHolder(); final LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(layout, parent, false); // get the number using the cursor position // add 1 to the int to start at 1 instead of 0 n = c.getPosition()+ 1; String lineNumber = Integer.toString(n); int setsColumn = c.getColumnIndex(ExerciseDbAdapter.KEY_SETS); String sets = c.getString(setsColumn); int repsColumn = c.getColumnIndex(ExerciseDbAdapter.KEY_REPS); String reps = c.getString(repsColumn); int weightColumn = c.getColumnIndex(ExerciseDbAdapter.KEY_WEIGHT); String weight = c.getString(weightColumn); viewHolder.number = (TextView) v.findViewById(R.id.labelNumber); viewHolder.setsText = (TextView) v.findViewById(R.id.labelSets); viewHolder.repsText = (TextView) v.findViewById(R.id.labelReps); viewHolder.weightText = (TextView) v.findViewById(R.id.labelWeight); if ( viewHolder.setsText != null &amp;&amp; viewHolder.repsText != null &amp;&amp; viewHolder.weightText != null ) { viewHolder.number.setText(lineNumber); viewHolder.setsText.setText(sets); viewHolder.repsText.setText(reps); viewHolder.weightText.setText(weight); } return v; } @Override public void bindView(View v, Context context, Cursor c) { viewHolder = new ViewHolder(); // use cursor to get the integer and add 1 to position c = getCursor(); n = c.getPosition()+ 1; String lineNumber = Integer.toString(n); int setsColumn = c.getColumnIndex(ExerciseDbAdapter.KEY_SETS); String sets = c.getString(setsColumn); int repsColumn = c.getColumnIndex(ExerciseDbAdapter.KEY_REPS); String reps = c.getString(repsColumn); int weightColumn = c.getColumnIndex(ExerciseDbAdapter.KEY_WEIGHT); String weight = c.getString(weightColumn); // set the fields for the view viewHolder.number = (TextView) v.findViewById(R.id.labelNumber); viewHolder.setsText = (TextView) v.findViewById(R.id.labelSets); viewHolder.repsText = (TextView) v.findViewById(R.id.labelReps); viewHolder.weightText = (TextView) v.findViewById(R.id.labelWeight); if (viewHolder.setsText != null &amp;&amp; viewHolder.repsText != null &amp;&amp; viewHolder.weightText != null ) { viewHolder.number.setText(lineNumber); viewHolder.setsText.setText(sets); viewHolder.repsText.setText(reps); viewHolder.weightText.setText(weight); } } </code></pre> <p>}</p>

    3. COYou should be able to use Cursor.getPosition to know the related line number. // you can also share your SimpleCursorAdapter sketch to let people how you work with it.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
