Android : Call Inner class function. Not working

[speedyguy]

I need to call an inner class method from outer class. The following code i have written which shows no error but on runtime it throws android error box asking me to force close. I need inner class as i want to extend a class for its method. Is there anyway? Where am i going wrong

Thanks



public class ListtestActivity extends Activity {
/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new sub1().called();
}

public static class sub1 extends ListActivity
{
public void called()
{
final String[] COUNTRIES = new String[] {"arya","suhail","gogu"};
/*
int i = 0;
File fileList = new File("/sdcard");
if (fileList != null){
File[] filenames = fileList.listFiles();
for (File tmpf : filenames){
String fname = tmpf.getName();
COUNTRIES[i++]=fname;
}
} */

setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES));

ListView lv = getListView();
lv.setTextFilterEnabled(true);

lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show();
}
});
}
}

}
