I want to fill out my ListView
with some data and I use SimpleAdapter
. But I think SimpleAdapter
only works with List<HashMap<String, String>>
and I've List<Object>
like follow codes:
What can I do? Is there any way?
List<DSarchive> programs = ...;
String[] from = new String[] {"name", "time", "day", "month"};
int[] to = new int[] { R.id.text1, R.id.text2, R.id.text3, R.id.text4};
SimpleAdapter adapter = new SimpleAdapter(getActivity(), programs, R.layout.my_list_row, from, to);
// ^ how can I use this "programs" List???
lv.setAdapter(adapter);
I want to use adapter List
in MyObject
.
MyObject class:
public class MyObject{
public ArrayList<String> links;
public String name;
public List<HashMap<String, String>> adapter;
.
.
.
}
Try using an ArrayAdapter
ArrayList<String> arrayList = new ArrayList<String>();
arrayList.add("temp1");
arrayList.add("temp2");
ListView listView = new ListView(getActivity());
listView.setAdapter(new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1, arrayList));
EDIT
The SimpleListAdapter
is not constrained to only use Strings
. It does require a String
key, but it can map to any object. For example, I used the following code to create a ListView
that contains an Icon with two supporting TextViews
. Hope this helps.
List<Map<String, Object>> data = new ArrayList<Map<String,Object>>();
Map<String, Object> dataMap = new HashMap<String, Object>(3);
dataMap.put("Item1", dataObject); //icon
dataMap.put("Item2", dataString);
dataMap.put("Item3", dataString2);
data.add(dataMap);
dataMap = new HashMap<String, Object>(2);
dataMap.put("Item1", dataObject); //icon
dataMap.put("Item2", dataString);
dataMap.put("Item3", dataString2);
data.add(dataMap);
SimpleAdapter adapter = new SimpleAdapter(getActivity().getBaseContext(),
(List<? extends Map<String, ?>>) data,
R.layout.layoutFile2,
new String[] {"Item1", "Item2", "Item3"} ,
new int[] {R.id.item1, R.id.item2, R.id.item3}){
//overload the getChildView or any other Override methods
};
