It has a Spinner, a textview and a bot;
I have this connection that does the search to the bank to get the last 100 record
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Dao_Hist_Alarmes {
public String nomeTabela() {
String nomeData = "";
String nomeAlarme = "";
String nomeRecebe = "";
ConexaoDao conexao = new ConexaoDao();
ObjetoConexao objConexao = new ObjetoConexao();
objConexao.db_connect_string = "ufv.ddns.me:5433";
objConexao.db_name = "Celular";
objConexao.db_userid = "sa";
objConexao.db_password = "flextelecom";
Connection conn = conexao.dbConnect(objConexao);
if (conn == null) {
nomeData = "Não foi possivel se conectar ao banco de dados";
nomeAlarme = "Não foi possivel se conectar ao banco de dados";
nomeRecebe = "Não foi possivel se conectar ao banco de dados";
} else if (conn != null) try {
Statement statement = conn.createStatement();
String queryString = "select TOP 100 Area,E3TimeStamp,Message from Alarmescelular Where AREA = 'BIBLIOTECA UFV' order By E3TimeStamp DESC ";
ResultSet rs;
rs = statement.executeQuery(queryString);
if (rs.next()) {
nomeData = rs.getString("E3TimeStamp");
nomeAlarme = rs.getString("Message");
nomeRecebe = nomeData + " " + nomeAlarme;
}
} catch (SQLException e) {
nomeRecebe = e.getMessage();
}
return nomeRecebe;
}
}
and here I get the data and upload to the textview
public class Act_Hist_Alarmes extends AppCompatActivity implements View.OnClickListener {
private Spinner Estacoes;
private TextView tvResultPesquisa;
private Button btnFechar;
private Button btnPesquisar;
String ESTACAO1 = "BIBLIOTECA UFV";
String ESTACAORECEBIDA;
Dao_Hist_Alarmes DHA;
String FalhaCon = "Não foi possivel se conectar ao banco de dados";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.act_hist_alarmes);
Estacoes = (Spinner) findViewById(R.id.Spn_Estacoes);
tvResultPesquisa = (TextView) findViewById(R.id.tvResultPesquisa);
btnFechar = (Button) findViewById(R.id.btnFechar);
btnFechar.setOnClickListener(this);
btnPesquisar = (Button) findViewById(R.id.btnPesquisar);
btnPesquisar.setOnClickListener(this);
ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.Sistema_Mobile, android.R.layout.simple_spinner_item);
Estacoes.setAdapter(adapter);
final AdapterView.OnItemSelectedListener escolha = new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String item = Estacoes.getSelectedItem().toString();
ESTACAORECEBIDA = item;
Toast.makeText(getApplicationContext(),"teste: "+ESTACAORECEBIDA, Toast.LENGTH_SHORT).show();
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
Estacoes.setOnItemSelectedListener(escolha);
}
String nomeRecebeAL1;
public void onClick(View v) {
if (v.getId() == R.id.btnFechar) {
finish();
} else if (v.getId() == R.id.btnPesquisar) {
DHA = new Dao_Hist_Alarmes();
nomeRecebeAL1 = DHA.nomeTabela();
tvResultPesquisa.setTextColor(Color.parseColor("#FF2D5E46"));
tvResultPesquisa.setText(nomeRecebeAL1);
}
}
But the same one only shows me in the textiview the first record.
Can anyone help me figure out what's wrong?
