    <p>I can't get a custom layout in expandablelistview to work, that refreshes on a click of a child child.</p> <p>In the example you have the method MyExpandableListAdapter -> getChildView, where the child inflates a custom layout R.layout.list_out_item (what is some textviews and buttons).</p> <p>Now I want that if I click a button that the child and parent of that childview is updated. How can I achieve this? I was thinking about refreshing the parent and child, because collapsing forces an update, but other solutions are also welcome.</p> <p>For an example</p> <pre><code>public class Sample extends ExpandableListActivity { ExpandableListAdapter mAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Set up our adapter mAdapter = new MyExpandableListAdapter(); setListAdapter(mAdapter); } } public class MyExpandableListAdapter extends BaseExpandableListAdapter { private Map&lt;Ability, Integer&gt; abilityMods; private List&lt;Skill&gt; skills = SkillList(); private List&lt;Skill&gt; SkillList() { List&lt;Skill&gt; skills = new Vector&lt;Skill&gt;(); abilityMods = Player.getAbilityModifier(); skills.add(new Skill(abilityMods, "Appraise", 2, Ability.Dex, 2)); skills.add(new Skill(abilityMods, "Autohypnosis", 0, Ability.Int, -7)); skills.add(new Skill(abilityMods, "Craft", 0, Ability.Dex, 0)); return skills; } public MyExpandableListAdapter() { super(); abilityMods = Player.getAbilityModifier(); } public long getChildId(int groupPosition, int childPosition) { return childPosition; } public int getChildrenCount(int groupPosition) { return 1; } public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, final ViewGroup parent) { LayoutInflater infalInflater = getLayoutInflater(); convertView = infalInflater.inflate(R.layout.list_out_item, null); final Skill skill = getChild(groupPosition, childPosition); TextView tv = (TextView) convertView.findViewById(R.id.abilityMod); tv.setText(toString(skill.abillityMod())); Button rankMod = (Button) convertView.findViewById(R.id.rankMod); rankMod.setText(toString(skill.Ranks)); rankMod.setOnClickListener(new OnClickListener() { public void onClick(View v) { skill.Ranks++; } }); return convertView; } private String toString(int value) { if (value &gt;= 0) return ("+" + String.valueOf(value)); else return (String.valueOf(value)); } public Skill getGroup(int groupPosition) { return skills.get(groupPosition); } @Override public Skill getChild(int groupPosition, int childPosition) { return getGroup(groupPosition); } public int getGroupCount() { return skills.size(); } public long getGroupId(int groupPosition) { return groupPosition; } public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { LayoutInflater infalInflater = getLayoutInflater(); convertView = infalInflater .inflate(R.layout.list_header_item, null); TextView skillName = (TextView) convertView .findViewById(R.id.skillName); Skill skill = getGroup(groupPosition); TextView skillPower = (TextView) convertView .findViewById(R.id.skillPower); int TotalMod = skill.TotalModifier(); if (TotalMod &gt;= 0) skillPower.setText("+" + String.valueOf(TotalMod)); else skillPower.setText(String.valueOf(TotalMod)); return convertView; } public boolean isChildSelectable(int groupPosition, int childPosition) { return true; } public boolean hasStableIds() { return true; } } </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.
