Android Custome ListView with checkbox OnCheckedChangeListener
The setting op of my click listener for each checkbox in my custom list items is causing the application to crash.
Below is a copy of the code section that I have made to got through and load up each listViewItem.
Below is a copy of the code section that I have made to got through and load up each listViewItem.
//SET UP MAIN LIST
lv1 = (ListView)findViewById(R.id.mainList);
double listTotal = 0;
if(!itemList.isEmpty())
{
//Toast.makeText(this, "Entered Setup Main loop", Toast.LENGTH_SHORT).show();
ArrayList<HashMap<String, String>> mylist =
new ArrayList<HashMap<String,String>>();
for (int i = 0; i <= itemList.size()-1; i++)
{
HashMap<String, String> map = new HashMap<String, String>();
map.put("id", Integer.toString(itemList.get(i).getItem_id()));
map.put("top", itemList.get(i).getName());
map.put("bottom", String.valueOf(itemList.get(i).getPrice()));
mylist.add(map);
listTotal = listTotal + itemList.get(i).getPrice();
final String name = itemList.get(i).getName();
CheckBox needItem = (CheckBox)lv1.findViewById(R.id.listneeded);
needItem.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
//createToast("Item: " + name);
}
});
}
SimpleAdapter lItems = new SimpleAdapter(this,mylist,R.layout.listitemlayout,
new String[]{"id", "top", "bottom"}, new int[]{R.id.itemid, R.id.topText, R.id.bottomText});
lv1.setAdapter(lItems);
}

Sorry for the delayed responce.
Your right my lv1.findViewById(R.id.list needed) is returning null. I think I may be going about settign up this listView wrong.
Is there a better example that shows how to set the eventListeners for the custome listView items?

returns null. You should do your setter in getView() of the adapter
