Hi
I'd like to refresh the Listview items. These items are populated from SQLite database. My code is below
public class Weeve extends Activity {
private String[] lv_arr;
protected ListView CView;
private DBAdapter mDbHelper;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new DBAdapter(this);
mDbHelper.open();
Cursor c = mDbHelper.getAll();
if (c.getCount() > 0)
{if (c.moveToFirst())
{
ArrayList strings = new ArrayList();
do {
String mC = c.getString(0);
strings.add(mC);
} while (c.moveToNext());
lv_arr = (String[]) strings.toArray(new String[strings.size()]);
}
}
else Toast.makeText(this,
"No more Records",
Toast.LENGTH_SHORT).show();
c.close();
ListView CView = new ListView(this);
CView.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, lv_arr));
setContentView(CView);}}
I'd like to make refreshing this list view after adding, updating or deleting SQLite table. These operations are called by content or option menu. I tried to create these code into a separated function and call it after every operation. But can't. I think setContentView(CView) statement.
I also tried to use SimpleCursorAdapter like notepad sample from Android.com. I got Thread error. Help me.
