    <p>I'm currently attempting to override a simplecursor adapter to allow me to use a imagbutton for each listitem.</p> <p>Code so far: </p> <pre><code>public class MyCursorAdapter extends SimpleCursorAdapter { Cursor mCursor; final int tIndex; final class ViewHolder{ public TextView textView; public ImageButton imageButton; } public MyCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); mCursor = c; tIndex = mCursor.getColumnIndex(DBAdapter.TASK); } @Override public View getView(int position, View convertView, ViewGroup parent) { if (mCursor.moveToPosition(position)){ ViewHolder viewHolder; final int i = position; if (convertView == null){ LayoutInflater inflater = MainActivity.this.getLayoutInflater(); viewHolder = new ViewHolder(); convertView = inflater.inflate(R.layout.listview,parent,false); viewHolder.textView = (TextView)convertView.findViewById(R.id.taskName); viewHolder.imageButton = (ImageButton)convertView.findViewById(R.id.edit_task); viewHolder.imageButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Log.d("LOG_TAG", "It Works: " + i); } }); convertView.setTag(viewHolder); } else { viewHolder = (ViewHolder)convertView.getTag(); } String task = mCursor.getString(tIndex); viewHolder.textView.setText(task); } return convertView; } } </code></pre> <p>I use my parent activity to display the contents of the database, and use an alternate activity to add data to the database. I call finish() on the alternate activity to ensure the user is returned to the parent activity, in the parent activity in the onResume() method I use: </p> <pre><code>@Override protected void onResume() { super.onResume(); cursor.moveToFirst(); myCursorAdapter.swapCursor(cursor = db.getAllRows()); list.startLayoutAnimation(); amountTasks(); } </code></pre> <p>When the user is returned to the parent activity, the data is incorrectly showed, the text of the listview will be a duplicate of the last entry, and the position will be 0.</p> <p>I have found that if i change the return statement to:</p> <pre><code>return super.getView(position,convertView,parent) </code></pre> <p>The text is correctly shown, but the position still returns 0.</p> <p>Any idea why this is happening?</p>

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).
