1.创建一个名为"TransportRouteDB"的SQLite数据库，并在其中创建名为"Route"的表，该表将存储公共交通线路的信息。以下是表结构：

CREATE TABLE Route ( ID INTEGER PRIMARY KEY, RouteName TEXT, Departure TEXT, Destination TEXT, TransportType TEXT, DepartureTime TEXT, ArrivalTime TEXT, Duration TEXT );

2.将公共交通线路信息存储在SQLite数据库中。以下是一个示例代码：

//初始化数据库 TransportRouteDB transportRouteDB = TransportRouteDB.getInstance(context); SQLiteDatabase db = transportRouteDB.getWritableDatabase();

//创建一个ContentValues对象，用于存储公共交通线路信息 ContentValues values = new ContentValues(); values.put("RouteName", "路线名称"); values.put("Departure", "起点站"); values.put("Destination", "终点站"); values.put("TransportType", "交通方式"); values.put("DepartureTime", "出发时间"); values.put("ArrivalTime", "到达时间"); values.put("Duration", "行程时间");

//将信息插入到"Route"表中 long result = db.insert("Route", null, values); if (result == -1) { //插入失败的逻辑处理 } else { //插入成功的逻辑处理 }

3.从SQLite数据库中检索公共交通路线信息。以下是一个示例代码：

//初始化数据库 TransportRouteDB transportRouteDB = TransportRouteDB.getInstance(context); SQLiteDatabase db = transportRouteDB.getReadableDatabase();

//构造一个查询语句，用于检索所有从起点站到终点站的公共交通路线 String selection = "Departure = ? AND Destination = ?"; String[] selectionArgs = {"起点站", "终点站"}; Cursor cursor = db.query("Route", null, selection, selectionArgs, null, null, null);

//使用循环遍历游标，将检索结果放入一个List对象中 List routeList = new ArrayList<>(); while (cursor.moveToNext()) { Route route = new Route(); route.setRouteName(cursor.getString(cursor.getColumnIndex("RouteName"))); route.setDeparture(cursor.getString(cursor.getColumnIndex("Departure"))); route.setDestination(cursor.getString(cursor.getColumnIndex("Destination"))); route.setTransportType(cursor.getString(cursor.getColumnIndex("TransportType"))); route.setDepartureTime(cursor.getString(cursor.getColumnIndex("DepartureTime"))); route.setArrivalTime(cursor.getString(cursor.getColumnIndex("ArrivalTime"))); route.setDuration(cursor.getString(cursor.getColumnIndex("Duration")));
