copied!<p>I've solved the issue. </p> <p>1) I have used the class AlmanacSQLiteDatabaseAdapter.java used in Almanac 0.0.17 (open source project) that you can find here: <a href="http://code.google.com/p/almanac/source/browse/trunk/Almanac/src/it/almanac/AlmanacSQLiteDatabaseAdapter.java?r=56" rel="nofollow">link</a>. You can fit to your needs (in my case I'have renamed to DatabaseHelper);</p> <p>2) This is the class that uses the Helper (it is a listview that do sql rawquery reading strings in a EditText - it is an arrangement of this tutorial "coenraets.org/blog/android-samples/androidtutorial/":</p> <pre><code>public class MiaList extends Activity { protected EditText searchText; protected SQLiteDatabase db; protected Cursor cursor; protected ListAdapter ladapter; protected ListView miaList; private static final String DATABASE_NAME = "miodb.jpg"; /* L'ESTENSIONE JPG (o mp3, mov) questo perchè android ha il limite di 1 mb per i file di testo o simili nella asset, mentre NON HA limiti per i file multimediali! Nel mio caso si tratta di 4mb */ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //qui sotto richiamo la classe DatabaseHelper DatabaseHelper dbAdapter = DatabaseHelper.getInstance(this, DATABASE_NAME); /*note di Vytek*/ // OK Dovrei usare aSQLiteDatabaseAdapter.getDatabase(); ma questo crea // problemi nella fase di OnPause quando premo Back cosi' invece non // ottengo errori // e viene fatta la normale copia del DB (13/8/2010 23.18) // db = aSQLiteDatabaseAdapter.getWritableDatabase(); // Per ovviare a questo problema controllo se e' la prima volta che // chiamo applicazione if (getFirstRun()) { db = dbAdapter.getDatabase(); setRunned(); } else { db = dbAdapter.getWritableDatabase(); } searchText = (EditText) findViewById (R.id.searchText); miaList = (ListView) findViewById (R.id.list); } private void setRunned() { // TODO Auto-generated method stub } private boolean getFirstRun() { // TODO Auto-generated method stub return false; } public void search(View view) { String text = searchText.getText().toString(); // || è l'operatore "concatena" in SQLite if (text.length()<15){ cursor = db.rawQuery("SELECT *FROM miatable WHERE AAA || ' ' || BBB || ' ' || CCC LIKE ? LIMIT 30", new String[]{"%" + searchText.getText().toString() + "%"}); ladapter = new SimpleCursorAdapter( this, R.layout.mialist_list_item, cursor, new String[] {"_id", "AAA", "BBB", "CCC"}, new int[] {R.id._id, R.id.AAA, R.id.BBB, R.id.CCC}); miaList.setAdapter(ladapter); //istruzione da eseguire } else { cursor = db.rawQuery("SELECT * FROM miatable WHERE AAA || BBB LIKE ? LIMIT 30", new String[]{"%" + searchText.getText().toString().substring(6,10) + "%" + searchText.getText().toString().substring(11,15) + "%"}); ladapter = new SimpleCursorAdapter( this, R.layout.mialist_list_item, cursor, new String[] {"_id", "AAA", "BBB", "CCC"}, new int[] {R.id._id, R.id.AAA, R.id.BBB, R.id.CCC}); miaList.setAdapter(ladapter); //istruzione da eseguire } } } </code></pre> <p>Of course the SQLite DB "miodb.jpg" must be in the asset folder of eclipse's workspace.</p> <p><strong>PS</strong> <em>I have used jpg extension for the db beacause the asset folder has a 1Mb limit for db or txt or xml extension.</em></p>
