如何使用sqlite数据库在android中制作每日一词

public class DatabaseHelper extends SQLiteOpenHelper {
    private static final String DB_NAME = "words.db";
    private static final int DB_VERSION = 1;

    public DatabaseHelper(Context context) {
        super(context, DB_NAME, null, DB_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // 不需要在此处创建表格，因为已经在数据库文件中创建了
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 如果需要升级数据库，可以在此处处理
    }
}

DatabaseHelper dbHelper = new DatabaseHelper(context);
SQLiteDatabase db = dbHelper.getReadableDatabase();

String query = "SELECT word FROM words ORDER BY RANDOM() LIMIT 1";
Cursor cursor = db.rawQuery(query, null);

if (cursor.moveToFirst()) {
    String word = cursor.getString(cursor.getColumnIndex("word"));
    // 在界面上展示每日一词
}

cursor.close();

db.close();
