用android中的sqllite数据库写一个关于古诗的增加、删除，以及按照题目修改和查询功能的笔记本项目，请写一个详细的包括布局文件和java文件的示例

好的，我可以为您提供一个简单的示例。

首先，您需要创建一个包含以下组件的布局文件：

1. 一个EditText用于输入古诗题目
2. 一个EditText用于输入古诗内容
3. 一个添加按钮
4. 一个删除按钮
5. 一个修改按钮
6. 一个查询按钮
7. 一个ListView用于显示所有的古诗列表

接下来，您需要编写一个Java类来处理数据库操作。这个类应该包括以下方法：

1. onCreate()方法用于创建数据库表
2. addPoem()方法用于添加新的古诗
3. deletePoem()方法用于从数据库中删除古诗
4. updatePoem()方法用于修改古诗
5. getAllPoems()方法用于获取所有的古诗列表
6. searchPoem()方法用于根据古诗题目搜索古诗

以下是示例代码：

布局文件 `activity_main.xml`:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16dp">
    
    <EditText
        android:id="@+id/edit_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请输入古诗题目" />
        
    <EditText
        android:id="@+id/edit_content"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请输入古诗内容" />
        
    <Button
        android:id="@+id/btn_add"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="添加" />
        
    <Button
        android:id="@+id/btn_delete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="删除" />
        
    <Button
        android:id="@+id/btn_update"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="修改" />
        
    <Button
        android:id="@+id/btn_search"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="查询" />
        
    <ListView
        android:id="@+id/list_poems"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
        
</LinearLayout>

Java文件 `MainActivity.java`:

public class MainActivity extends AppCompatActivity {

    private EditText mTitleEditText;
    private EditText mContentEditText;
    private Button mAddButton;
    private Button mDeleteButton;
    private Button mUpdateButton;
    private Button mSearchButton;
    private ListView mPoemsListView;

    private SQLiteDatabase mDatabase;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTitleEditText = findViewById(R.id.edit_title);

        mUpdateButton = findViewById(R.id.btn_update);
        mSearchButton = findViewById(R.id.btn_search);
        mPoemsListView = findViewById(R.id.list_poems);

        mDatabase = openOrCreateDatabase("poems.db", MODE_PRIVATE, null);

        String createTableSql = "CREATE TABLE IF NOT EXISTS poems (id INTEGER PRIMARY KEY AUTOINCREMENT, title TEXT, content TEXT)";
        mDatabase.execSQL(createTableSql);

        mAddButton.setOnClickListener(new View.OnClickListener() {

                String content = mContentEditText.getText().toString();

                addPoem(title, content);

                mTitleEditText.setText("");
                mContentEditText.setText("");

                getAllPoems();
            }
        });

        mDeleteButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String title = mTitleEditText.getText().toString();

                deletePoem(title);

                mTitleEditText.setText("");

                getAllPoems();
            }
        });

        mUpdateButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String title = mTitleEditText.getText().toString();

                mTitleEditText.setText("");
                mContentEditText.setText("");

                getAllPoems();
            }
        });

        mSearchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String title = mTitleEditText.getText().toString();

                searchPoem(title);
            }
        });

        getAllPoems();
    }

    private void addPoem(String title, String content) {
        String insertSql = "INSERT INTO poems (title, content) VALUES (?, ?)";
        SQLiteStatement statement = mDatabase.compileStatement(insertSql);
        statement.bindString(1, title);
        statement.bindString(2, content);
        statement.executeInsert();
    }

    private void deletePoem(String title) {
        String deleteSql = "DELETE FROM poems WHERE title = ?";
        SQLiteStatement statement = mDatabase.compileStatement(deleteSql);
        statement.bindString(1, title);
        statement.executeUpdateDelete();
    }

    private void updatePoem(String title, String content) {
        String updateSql = "UPDATE poems SET content = ? WHERE title = ?";
        SQLiteStatement statement = mDatabase.compileStatement(updateSql);
        statement.bindString(1, content);
        statement.bindString(2, title);
        statement.executeUpdateDelete();
    }

    private void getAllPoems() {
        String selectSql = "SELECT * FROM poems";
        Cursor cursor = mDatabase.rawQuery(selectSql, null);

        List<String> poems = new ArrayList<>();
        while (cursor.moveToNext()) {
            String title = cursor.getString(cursor.getColumnIndex("title"));
            String content = cursor.getString(cursor.getColumnIndex("content"));
            String poem = title + ": " + content;
            poems.add(poem);
        }

        ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, poems);
        mPoemsListView.setAdapter(adapter);
    }

    private void searchPoem(String title) {
        String selectSql = "SELECT * FROM poems WHERE title = ?";
        Cursor cursor = mDatabase.rawQuery(selectSql, new String[]{title});

        List<String> poems = new ArrayList<>();
        while (cursor.moveToNext()) {
            String content = cursor.getString(cursor.getColumnIndex("content"));
            String poem = title + ": " + content;
            poems.add(poem);
        }

        ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, poems);
        mPoemsListView.setAdapter(adapter);
    }
}

这个示例还可以进行更多的优化和完善，例如添加数据验证、异常处理等。但这应该足以让您理解如何在Android中使用SQLite数据库来创建一个简单的笔记本应用程序。
