大家好，我已经尝试了一些代码，但如果有人可以帮助我，我希望没有任何工作。下面我将输入我的代码

public ConnectionClass() {

}
OrdemFabricoActivity：
public class OrdemFabricoActivity extends Activity {
ConnectionClass connectionclass;
ListView lst;
SimpleAdapter ADAhere;
String usernameS;
String datets;
String call, db, un, passwords;
Connection connect;

ConnURL = "jdbc:jtds:sqlserver://" + _server + ";" + "databaseName=" + _DB + ";user=" + _user + ";password=" + _pass + ";";
conn = DriverManager.getConnection(ConnURL);
} catch (SQLException se) {
Log.e("ERRO", se.getMessage());
} catch (ClassNotFoundException e) {
Log.e("ERRO", e.getMessage());
} catch (Exception e) {
Log.e("ERRO", e.getMessage());

return conn;
}
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ordemfabrico);
lst = (ListView) findViewById(R.id.EnterPays_atomPaysList);
/************* CONNECTION DATABASE VARIABLES ***************/
connectionclass = new ConnectionClass();
call = connectionclass.getip();
un = connectionclass.getun();
passwords = connectionclass.getpassword();
db = connectionclass.getdb();
connect = CONN(un, passwords, db, call);
String querycmd = "select NUMOF, COD_ART, DESC_ART, OBSERVACOES, QUANT from tabof where tabof.ID_TO <> 5";
try {
Statement statement = connect.createStatement();
rs = statement.executeQuery(querycmd);
List<Map<String, String>> data = null;
data = new ArrayList<Map<String, String>>();
while (rs.next()) {
Map<String, String> datanum = new HashMap<String, String>();
datanum.put("A", rs.getString("COD_ART"));
//datanum.put("B", rs.getString("QUANT"));
data.add(datanum);
}
String[] fromwhere = { "A" };
int[] viewswhere = { R.id.Codart };
ADAhere = new SimpleAdapter(OrdemFabricoActivity.this, data, R.layout.ofselect, fromwhere, viewswhere);
lst.setAdapter(ADAhere);
} catch (SQLException e) {
Toast.makeText(OrdemFabricoActivity.this, e.getMessage().toString(), Toast.LENGTH_LONG).show();
}
}
}
这是我的代码，这是我使用此代码得到的结果，当我进行此活动时，我的手机屏幕是黑色的，没有任何反应。如果有人知道如何做到这一点，请帮助我。
