以下は私が使用しているコードです..そしてそれが表示したエラーも..コードの各行を調べましたが、理解できませんでした..助けてください..
public class CenterCollectionDatabase extends Activity {
public static final String KEY_ID = "id";
public static final String KEY_ROUNDID = "round";
public static final String KEY_PLAYERID = "playerid";
public static final String KEY_MAAL = "maal";
public static final String KEY_POINT = "point";
public static final String KEY_WON = "won";
private static final String DATABASE_NAME ="center_collection";
private static final String DATABASE_TABLE= "transaction";
private static final int DATABASE_VERSION = 1;
private DbHelper ourHelper;
private final Context ourContext;
private SQLiteDatabase ourDatabase;
private static class DbHelper extends SQLiteOpenHelper{
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("CREATE TABLE " + DATABASE_TABLE +" ("+
KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "+
KEY_ROUNDID + " INTEGER, "+
KEY_PLAYERID + " INTEGER, "+
KEY_POINT + " INTEGER, "+
KEY_MAAL + " INTEGER, "+
KEY_WON+ " INTEGER );"
);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
onCreate(db);
}
}
public CenterCollectionDatabase(Context c)
{
ourContext = c;
}
public CenterCollectionDatabase open() throws SQLException{
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
public void close()
{
ourHelper.close();
}
public long add_score(int round, int playerid, int point, int maal, int won) {
ContentValues cv = new ContentValues();
cv.put(KEY_ROUNDID, round);
cv.put(KEY_PLAYERID, playerid);
cv.put(KEY_POINT, point);
cv.put(KEY_MAAL, maal);
cv.put(KEY_WON, won);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
}
以下は、データベースにデータを保存するために使用されるコードです
if(counter>0)
{
Toast.makeText(getApplicationContext(), "Oops Mike! please fill all fields", Toast.LENGTH_SHORT).show();
}else{
CenterCollectionDatabase db = new CenterCollectionDatabase(ScoreEntry.this);
db.open();
for(int i=0; i<number_of_player; i++)
{
int round = 1;
int playerid = i;
int point = Integer.parseInt(Spoint[i]);
int maal = Integer.parseInt(Smaal[i]);
int won_who = 0;
db.add_score(round, playerid, point, maal, won_who);
}
db.close();
Toast.makeText(getApplicationContext(), "Record Sucessfully Saved", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(ScoreEntry.this, ScoreBoard.class);
startActivity(intent);
}
以下はエラーです
