I have:
package com.es.tele;
import .....
public class tele extends TabActivity {
/** Called when the activity is first created. */
private TextView seleccion;
private ProgressDialog progressdialog;
String horaIn;
String horaFi;
String canal;
int posicion;
base baseDatos = new base(this,"programacion",null,1);
SQLiteDatabase db = baseDatos.getWritableDatabase();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tabhost = getTabHost();
And then in the base class:
public class base extends SQLiteOpenHelper {
//Sentencia SQL para crear la tabla de Usuarios
String sqlCreate = "CREATE TABLE LAUNO (codigo INTEGER, programa
TEXT, descripcion TEXT);";
public base(Context contexto, String nombre,
CursorFactory factory, int version) {
super(contexto, nombre, factory, version);
}
@Override
public void onCreate(SQLiteDatabase db) {
//Se ejecuta la sentencia SQL de creación de la tabla
db.execSQL(sqlCreate);
}
@Override
public void onUpgrade(SQLiteDatabase db, int versionAnterior, int
versionNueva) {
//Se elimina la versión anterior de la tabla
db.execSQL("DROP TABLE IF EXISTS LAUNO");
//Se crea la nueva versión de la tabla
db.execSQL(sqlCreate);
}
}
Could you help me please?
Many thanks and sorry for my english!
