This is my Activity Auto.java

public class Auto extends ListActivity {
private static final String TABLE_NAME = "auto";
private static final String FIELD_ID = "SNo";
private static final String FIELD_NAME = "Name";
private static final String FIELD_NUM = "Number";
SqlHandler sqlHandler;

private ListView listView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_auto);

    ActionBar actionBar = getActionBar();

    actionBar.setDisplayHomeAsUpEnabled(true);

    sqlHandler = new SqlHandler(this);
    showlist();

}


private void showlist() {

    ArrayList<listRowAuto> contactList = new ArrayList<listRowAuto>();
    contactList.clear();
    String query = "SELECT Name,Number FROM auto ";
    Cursor c1 = sqlHandler.selectQuery(query);
    if (c1 != null && c1.getCount() != 0) {
        if (c1.moveToFirst()) {
            do {
                listRowAuto contactListItems = new listRowAuto();

                contactListItems.setName(c1.getString(c1
                        .getColumnIndex("name")));
                contactListItems.setPhone(c1.getString(c1
                        .getColumnIndex("phone")));
                contactList.add(contactListItems);

            } while (c1.moveToNext());
        }
    }
    c1.close();

    listAdapterAuto contactListAdapter = new listAdapterAuto(
            Auto.this, contactList);
    listView.setAdapter(contactListAdapter);

}
