同一listview适配器中的Android 2 sqlite数据库表

我制作了一个android SQLite数据库，其中包含两个表，每个表都在单独的活动中执行。我试着把它们放在同一个列表视图中

这是我的活动列表视图所在的位置

public class MainActivity extends ActionBarActivity {

    ListView lv;
    SQLController dbcon;
    TextView incomeID_tv, incomePayer_tv, incomeAmount_tv;
    TextView incomeDate_tv, incomeCategory_tv, incomePayments_tv;
    TextView expenseID_tv, expensePayee_tv, expenseAmount_tv;
    TextView expenseDate_tv, expenseCategory_tv, expensePayments_tv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        dbcon = new SQLController(this);
        dbcon.open();
        lv = (ListView) findViewById(R.id.incomeList_id);

        Cursor cursor = dbcon.readIncomeData();
        String[] from = new String[] { DBHelper.INCOME_ID, DBHelper.INCOME_AMOUNT, DBHelper.INCOME_PAYER,
                DBHelper.INCOME_DATE, DBHelper.INCOME_CATEGORY, DBHelper.INCOME_PAYMENTS};
        int[] to = new int[] { R.id.income_id, R.id.income_amount, R.id.income_payer, R.id.income_date,
                R.id.income_category, R.id.income_payments};

        SimpleCursorAdapter adapter = new SimpleCursorAdapter(
                MainActivity.this, R.layout.income_entry, cursor, from, to);

        adapter.notifyDataSetChanged();
        lv.setAdapter(adapter);

        Cursor ecursor = dbcon.readExpenseData();
        String[] efrom = new String[] { DBHelper.EXPENSE_ID, DBHelper.EXPENSE_AMOUNT, DBHelper.EXPENSE_PAYEE,
                DBHelper.EXPENSE_DATE, DBHelper.EXPENSE_CATEGORY, DBHelper.EXPENSE_PAYMENTS};
        int[] eto = new int[] { R.id.expense_id, R.id.expense_amount, R.id.expense_payee, R.id.expense_date,
                R.id.expense_category, R.id.expense_payments};

        SimpleCursorAdapter eadapter = new SimpleCursorAdapter(
                MainActivity.this, R.layout.expense_entry, ecursor, efrom, eto);

        eadapter.notifyDataSetChanged();
        lv.setAdapter(eadapter);

        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override

问题是它只显示了费用。我认为问题出在适配器上，但我不知道如何将两者都包含在同一个适配器中。：）
