我有一个应用程序尝试通过 MainActivity 中的以下代码使用 JDBC 连接到 MySQL
public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Spinner s = (Spinner)findViewById(R.id.spinner1);
s.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View arg1,
int position, long arg3) {
if(position == 0)
{}
if(position == 1)
{
Intent i = new Intent();
i.setClass(MainActivity.this, Resultados.class);
startActivity(i);
}
if(position == 2)
{
Intent i = new Intent();
i.setClass(MainActivity.this, Clasificacion.class);
startActivity(i);
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
@Override
protected void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sqlThread.start();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Thread sqlThread = new Thread() {
public void run() {
try {
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection(
"jdbc:mysql://192.168.0.4:3306/fifa", "root", "root");
String stsql = "Select version()";
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(stsql);
rs.next();
System.out.println( rs.getString(1) );
conn.close();
} catch (SQLException se) {
System.out.println("oops! No se puede conectar. Error: " + se.toString());
} catch (ClassNotFoundException e) {
}
}
};
}
这一行有一个错误，我该如何修复它？
protected void onCreate1(Bundle savedInstanceState) {
如果我能够连接到数据库，这也不完全是这样，不是吗？谢谢
最佳答案
在protected void onCreate1(Bundle savingInstanceState) {之前，您应该有一个封闭的}，其方法为onCreate()。
