import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.widget.ListAdapter;
import android.widget.SimpleCursorAdapter;
public class Sprinter extends ListActivity {
/** Called when the activity is first created. */
final static String MY_DB_NAME = "Sprinter";
final static String MY_DB_TABLE = "Stations";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SQLiteDatabase myDB = null;
try {
myDB = this.openOrCreateDatabase(MY_DB_NAME, MODE_PRIVATE, null);
myDB.execSQL("CREATE TABLE IF NOT EXISTS " + MY_DB_TABLE + "_id integer primary key autoincrement, name varchar(100);");
myDB.execSQL("INSERT INTO " + MY_DB_TABLE + " (_id, name)" + " VALUES ('', 'Oceanside Transit Center');");
myDB.execSQL("INSERT INTO " + MY_DB_TABLE + " (_id, name)" + " VALUES ('', 'Coast Highway');");
Cursor mCursor = myDB.rawQuery("SELECT name" + " FROM " + MY_DB_TABLE, null);
startManagingCursor(mCursor);
ListAdapter adapter = new SimpleCursorAdapter(this, R.layout.list_item, mCursor, new String[] { "name" }, new int[] { R.id.Name });
this.setListAdapter(adapter);
this.getListView().setTextFilterEnabled(true);
