以下是一个使用SQLite数据库加载RecyclerView，并在EditText中输入一个单词的Android Studio示例代码：

1. 首先，在你的项目中添加以下依赖项到你的app的build.gradle文件中：

dependencies {
    implementation 'androidx.recyclerview:recyclerview:1.2.1'
    implementation 'androidx.sqlite:sqlite:2.1.0'
}

2. 创建一个名为Word的Java类，用于表示数据库中的单词：

public class Word {
    private int id;
    private String word;

    public Word(int id, String word) {
        this.id = id;
        this.word = word;
    }

    public int getId() {
        return id;
    }

    public String getWord() {
        return word;
    }
}

3. 创建一个名为DatabaseHelper的Java类，用于管理SQLite数据库：

public class DatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "words.db";
    private static final int DATABASE_VERSION = 1;
    private static final String TABLE_NAME = "words";
    private static final String COLUMN_ID = "id";
    private static final String COLUMN_WORD = "word";

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

    @Override
    public void onCreate(SQLiteDatabase db) {
        String createTable = "CREATE TABLE " + TABLE_NAME + " (" +
                COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                COLUMN_WORD + " TEXT)";
        db.execSQL(createTable);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
        onCreate(db);
    }

    public void insertWord(String word) {
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues contentValues = new ContentValues();
        contentValues.put(COLUMN_WORD, word);
        db.insert(TABLE_NAME, null, contentValues);
        db.close();
    }

    public List getAllWords() {
        List wordList = new ArrayList<>();
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.rawQuery("SELECT * FROM " + TABLE_NAME, null);

        if (cursor.moveToFirst()) {
            do {
                int id = cursor.getInt(cursor.getColumnIndex(COLUMN_ID));
                String word = cursor.getString(cursor.getColumnIndex(COLUMN_WORD));
                Word newWord = new Word(id, word);
                wordList.add(newWord);
            } while (cursor.moveToNext());
        }

        cursor.close();
        db.close();

        return wordList;
    }
}

4. 创建一个名为WordAdapter的Java类，用于将单词列表显示在RecyclerView中：

public class WordAdapter extends RecyclerView.Adapter {
    private List wordList;

    public class WordViewHolder extends RecyclerView.ViewHolder {
        public TextView wordTextView;

        public WordViewHolder(View view) {
            super(view);
            wordTextView = view.findViewById(R.id.wordTextView);
        }
    }

    public WordAdapter(List wordList) {
        this.wordList = wordList;
    }

    @Override
    public WordViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.word_item, parent, false);
        return new WordViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(WordViewHolder holder, int position) {
        Word word = wordList.get(position);
        holder.wordTextView.setText(word.getWord());
    }

    @Override
    public int getItemCount() {
        return wordList.size();
    }
}

5. 在res/layout目录下创建一个名为activity_main.xml的XML布局文件，用于显示RecyclerView和EditText：

6. 在res/layout目录下创建一个名为`word_item
