在android系统中管理sqlite？

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

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

    @Override
    public void onCreate(SQLiteDatabase db) {
        String createTableQuery = "CREATE TABLE IF NOT EXISTS my_table (id INTEGER PRIMARY KEY, name TEXT)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // Perform necessary database upgrades
    }
}

MyDatabaseHelper dbHelper = new MyDatabaseHelper(context);
SQLiteDatabase db = dbHelper.getWritableDatabase();

ContentValues values = new ContentValues();
values.put("name", "John Doe");
long newRowId = db.insert("my_table", null, values);

SQLiteDatabase db = dbHelper.getReadableDatabase();

String[] projection = {"id", "name"};
String selection = "name = ?";
String[] selectionArgs = {"John Doe"};
Cursor cursor = db.query("my_table", projection, selection, selectionArgs, null, null, null);

while (cursor.moveToNext()) {
    int id = cursor.getInt(cursor.getColumnIndexOrThrow("id"));
    String name = cursor.getString(cursor.getColumnIndexOrThrow("name"));
    // Process the retrieved data
}

cursor.close();

SQLiteDatabase db = dbHelper.getWritableDatabase();

ContentValues values = new ContentValues();
values.put("name", "Jane Smith");

String selection = "id = ?";
String[] selectionArgs = {"1"};

int count = db.update("my_table", values, selection, selectionArgs);

SQLiteDatabase db = dbHelper.getWritableDatabase();

String selection = "id = ?";
String[] selectionArgs = {"1"};

int count = db.delete("my_table", selection, selectionArgs);
