You have to do 2 things:
*1. Create your class relate Database a Table you want create*
package com.angelo.sqllite;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class MioDatabaseHelper extends SQLiteOpenHelper {
private static final String DB_NAME = "minchiature_db";
private static final int DB_VERSION = 1;
public MioDatabaseHelper(Context context) {
super(context, DB_NAME, null, DB_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
String sql = "";
sql += "CREATE TABLE agenda (";
sql += " _id INTEGER PRIMARY KEY,";
sql += " nome TEXT NOT NULL,";
sql += " cognome TEXT NOT NULL,";
sql += " telefono TEXT NOT NULL";
sql += ")";
db.execSQL(sql);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// Aggiornamento delle tabelle
}
}
*2.Use Your activity *
package com.angelo.sqllite;
import android.app.Activity;
import android.content.ContentValues;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.util.Log;
public class TestSqlLiteActivity extends Activity
{
private MioDatabaseHelper mioDatabaseHelper;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/***********CREATE A
DATABASE******************************************************/
mioDatabaseHelper = new MioDatabaseHelper(this);
SQLiteDatabase db = mioDatabaseHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("nome", "Mario");
values.put("cognome", "Rossi");
values.put("telefono", "061299178");
long id = db.insert("agenda", null, values);
values.put("nome", "Mario2");
values.put("cognome", "Rossi2");
values.put("telefono", "0612991782");
id = db.insert("agenda", null, values);
values.put("nome", "Mario3");
values.put("cognome", "Rossi3");
values.put("telefono", "0612991783");
id = db.insert("agenda", null, values);
String query = "SELECT _id FROM agenda WHERE cognome = ? ORDER BY
_id ASC";
String[] selectionArgs3 = { "Rossi" };
// I cursori sono gli oggetti di Android che permettono di navigare
all’interno di un result set, ossia
//nell’insieme dei risultati restituiti da una query.
Cursor cursor = null;
cursor = db.rawQuery(query, selectionArgs3);
int count = cursor.getCount();
System.out.println("il numero di dati contenuti nel database "+
count);
while (cursor.moveToNext()) {
id = cursor.getLong(0);
System.out.println("Questo è l'ID ====>"+id);
String nome = cursor.getString(1);
System.out.println("Questo è l'ID ====>"+nome);
String cognome = cursor.getString(2);
System.out.println("Questo è il COGNOME ====>"+cognome);
}
/***********DROP
TABLE***************************************************************/
db.execSQL("DROP TABLE agenda");
}
}
