Android，编译时出错，sqlite

标签： android sqlite logging

我正在尝试创建一个简单的数据库，但看起来它不会编译，可能是语法错误，我看不到...... 

package com.amf.stockliste;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class StockDatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "stock";

    private static final int DATABASE_VERSION = 1;

    // Instruction pour la création de la BD
    private static final String DATABASE_CREATE = "CREATE TABLE stock (_id INTEGER PRIMARY KEY AUTOINCREMENT, _symbole TEXT NOT NULL, _nom REAL, _valeur REAL, _quantite REAL, _description TEXT NOT NULL);";


    public StockDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Méthode appelée lors de la creation de la BD
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL("DATABASE_CREATE");
    }

    // Méthode appelée lors de la mise-à-jour de la BD
        @Override
    public void onUpgrade(SQLiteDatabase database, int oldVersion, int newVersion) {
        database.execSQL("DROP TABLE IF EXISTS stock");
        // Recreate table
        onCreate(database);
    }
}


public class StockDbAdapter {

    // Database fields
    public static final String KEY_ROWID = "_id";
    public static final String KEY_SYMBOLE = "symbole";
    public static final String KEY_COMPAGNIE = "compagnie";
    public static final String KEY_PRIX = "prix";
    public static final String KEY_QUANTITE = "quantite";
    public static final String KEY_DESCRIPTION = "description";
    private static final String DATABASE_TABLE = "stock";
    private Context context;
    private SQLiteDatabase database;
    private StockDatabaseHelper dbHelper;


    public StockDbAdapter(Context context) {
        dbHelper = new StockDatabaseHelper(context);
        database = dbHelper.getWritableDatabase();
    }

    public SQLiteDatabase open() throws SQLException {
        database = dbHelper.getWritableDatabase();
        return database;
    }
[...]

在MainActivity中我做了类似的事情：

私人StockDbAdapter dbAdapter; dbAdapter = new StockDbAdapter（getActivity（））;
