Android - Custom Icons in ListView
- by Ryan
Is there any way to place a custom icon for each group item? Like for phone I'd like to place a phone, for housing I'd like to place a house. Here is my code, but it keeps throwing a Warning and locks up on me.
ListView myList = (ListView) findViewById(R.id.myList);
//ExpandableListAdapter adapter = new MyExpandableListAdapter(data);
List<Map<String, Object>> groupData = new ArrayList<Map<String, Object>>();
Iterator it = data.entrySet().iterator();
while (it.hasNext())
{
//Get the key name and value for it
Map.Entry pair = (Map.Entry)it.next();
String keyName = (String) pair.getKey();
String value = pair.getValue().toString();
//Add the parents -- aka main categories
Map<String, Object> curGroupMap = new HashMap<String, Object>();
groupData.add(curGroupMap);
if (value == "Phone")
curGroupMap.put("ICON", findViewById(R.drawable.phone));
else if (value == "Housing")
curGroupMap.put("NAME", keyName);
curGroupMap.put("VALUE", value);
}
// Set up our adapter
mAdapter = new SimpleAdapter(
mContext,
groupData,
R.layout.exp_list_parent,
new String[] { "ICON", "NAME", "VALUE" },
new int[] { R.id.iconImg, R.id.rowText1, R.id.rowText2 }
);
myList.setAdapter(mAdapter);
The error i'm getting:
