    <p>I have the Vraag Class that i use to make the different items in the List. That class has an Array of the Antwoord class. For each Antwoord i want a togglebutton that i added with the for loop. The problem now is that when i scroll in the list it adds additional togglebuttons to the list items. Here is my adapter code:</p> <pre><code>public class VraagListAdapter extends ArrayAdapter&lt;Vraag&gt;{ public Context context; public List&lt;Vraag&gt; vragen; ViewHolder holder; int id = 0; public VraagListAdapter(Activity context, List&lt;Vraag&gt; vragen){ super(context, R.layout.vraag_item, vragen); this.context = context; this.vragen = vragen; } @Override public View getView(int position, View convertView, ViewGroup parent) { if(convertView == null) { LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.vraag_item, null, false); holder = new ViewHolder(); holder.vraag = (TextView)convertView.findViewById(R.id.tv_vraag); holder.group = (RadioGroup)convertView.findViewById(R.id.toggleGroup); holder.position = position; holder.toggle = new ToggleButton(context); convertView.setTag(holder); } else{ holder = (ViewHolder) convertView.getTag(); } holder.vraag.setText(vragen.get(position).getVraag()); final int positievraag = position; holder.group.setOnCheckedChangeListener(ToggleListener); for(Antwoord a : vragen.get(position).getAntwoorden()){ holder.toggle = new ToggleButton(context); holder.toggle.setText(a.getAntwoord()); holder.toggle.setTextOn(a.getAntwoord()); holder.toggle.setTextOff(a.getAntwoord()); holder.toggle.setId(id); if(a.getVisible() == false){ holder.toggle.setVisibility(ToggleButton.INVISIBLE); } holder.toggle.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { // your click actions go here ((RadioGroup)view.getParent()).check(view.getId()); vragen.get(positievraag).setAntwoord((String)holder.toggle.getText()); } }); id++; holder.group.addView(holder.toggle); } return convertView; } static class ViewHolder { TextView vraag; RadioGroup group; ToggleButton toggle; int position; } static final RadioGroup.OnCheckedChangeListener ToggleListener = new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(final RadioGroup radioGroup, final int i) { for (int j = 0; j &lt; radioGroup.getChildCount(); j++) { final ToggleButton view = (ToggleButton) radioGroup.getChildAt(j); view.setChecked(view.getId() == i); } } }; </code></pre> <p>}</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.
