    <p>I develop an Android App, so I'm trying to use the <code>ExpandableListView</code> to use two different layouts for each child. But I have a problem and can't seem to fix it. I thought the problem was that I didn't get the right child. Both children display the two layouts at the same time.</p> <p>This my <strong>class Adapter</strong> !</p> <pre><code>public class ExpandListAdapter extends BaseExpandableListAdapter { private Context context; private ArrayList&lt;ExpandListGroup&gt; groups; public ExpandListAdapter(Context context, ArrayList&lt;ExpandListGroup&gt; groups) { this.context = context; this.groups = groups; } public void addItem(ExpandListChild item, ExpandListGroup group) { if (!groups.contains(group)) { groups.add(group); } int index = groups.indexOf(group); ArrayList&lt;ExpandListChild&gt; ch = groups.get(index).getItems(); ch.add(item); groups.get(index).setItems(ch); } public Object getChild(int groupPosition, int childPosition) { //TODO Auto-generated method stub ArrayList&lt;ExpandListChild&gt; chList = groups.get(groupPosition).getItems(); return chList.get(childPosition); } @Override public int getChildTypeCount() { return 2; } public long getChildId(int groupPosition, int childPosition) { //TODO Auto-generated method stub //return childPosition; return (long)( groupPosition*50+childPosition ); } @Override public int getChildType(int groupPosition, int childPosition) { int result = 0; if (childPosition == getChildrenCount(groupPosition)-1) result = 1; return result; } public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View view, ViewGroup parent) { TextView textView = null; ExpandListChild child = (ExpandListChild) getChild(groupPosition, childPosition); /* if (view == null) { if(childPosition == 0){ LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE); view = infalInflater.inflate(R.layout.expandlist_child_item, null);} else if (childPosition == 1){ LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE); view = infalInflater.inflate(R.layout.child2, null); } }*/ if (view == null) { int itemType = getChildType(groupPosition,childPosition); LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE); //view = infalInflater.inflate(R.layout.expandlist_child_item, null); if(itemType == 0) { view = infalInflater.inflate(R.layout.expandlist_child_item, null); textView = (TextView) view.findViewById(R.id.tvChild); textView.setText("0"); //textView.setTag(child.getTag()); } else { view = infalInflater.inflate(R.layout.child2, null); textView = (TextView) view.findViewById(R.id.tvChild1); textView.setText("1"); textView.setTag(child.getTag());} /* switch (itemType) { case 0: { view = infalInflater.inflate(R.layout.expandlist_child_item, null);

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.
