Hi, I have a xml file call groups.xml.
I want to read the value "name" and store in array lv_arrr and load it
into an adapter:
lv1.setAdapter(new ArrayAdapter<String>(this, R.layout.group_list,
R.id.grouplist, lv_arrr));
The program crash during runtime. What did I do wrong in the code can
anyone help to take a look?
Many thanks.
---/res/xml/groups.xml---
<?xml version="1.0" encoding="utf-8"?>
<!--
This is a mock score XML chunk
-->
<groups>
<group
name="Apple" />
<group
name="Orange" />
<group
name="Pineapple" />
</groups>

public class Manual extends Activity {
private ListView lv1;
private String lv_arrr[];
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.manual);
XmlResourceParser allGroups =
getResources().getXml(R.xml.groups);
try {
processGroups(allGroups);
} catch (Exception e) {
// Log.e(DEBUG_TAG, "Failed to load malls", e);
}
lv1=(ListView)findViewById(R.id.myListView);
lv1.setAdapter(new ArrayAdapter<String>(this,
R.layout.group_list, R.id.grouplist, lv_arrr));
lv1.setTextFilterEnabled(true);
lv1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int
position, long id) {
AlertDialog.Builder adb=new AlertDialog.Builder(Manual.this);
adb.setTitle("LVSelectedItemExample");
adb.setMessage("Selected Item is =
"+lv1.getItemAtPosition(position));
adb.setPositiveButton("Ok", null);
adb.show();
}
});
}
