java parcelable

[Switch] Android Parcelable and Serializable, androidparcelable This article mainly introduces the functions, efficiency, difference and selection of Parcelable and Serializable. For details about Serializable, see the advanced understanding of Java serialization. 1. Role Serializable is used to save the attributes of an object to a local file, database, network

more efficient than standard Java serialization, it is also used to exchange data in aidl. Therefore, the display serialization technology like parcelable can greatly improve the data exchange performance. Serializable 　 The traditional Java and serializable technology implement the serializable interface. The principle is similar to that of parceble. They all c

By default, Aidl supports java basic types (int, long, boolean, etc.) and (String, List, Map, CharSequence ), how can I implement a custom type? To pass a custom type, first make the custom type support the parcelable protocol. The implementation steps are as follows: 1> the Parcelable interface must be implemented for the custom type, and implements the public v

This paper mainly introduces the function, efficiency, difference and choice of parcelable and Serializable, and introduces the advanced knowledge of Java serialization in the introduction of serializable.1. functionSerializable's role is to save the object's properties to local files, databases, network streams, RMI for easy data transfer, which can be within a program or between two programs.

The serializable and Parcelable interfaces can accomplish the serialization of objects, and we need two serialization methods when we need to transfer data through intent and binder. Also, we need objects to be persisted to the storage device or transmitted over the network to other clients, and this use also requires the use of Serializale to complete the serialization of the object. Both of these approaches are common in Android app development, but

For Android, passing complex types is primarily about converting its own class into a base byte array, and passing data between the activity is accomplished through intent. There are two main methods of the Android serialization object, which is to implement the serializable interface, or implement the Parcelable interface. The implementation of the serializable interface is supported by the Java SE itself,

interface content, but its extension is. aidl. Save it in the src directory. If other applications require IPC, the SRC of those applications will also carry this file. Android SDK tools automatically generates an ibinder interface file in the gen directory. Service must implement this ibinder interface as appropriate. Then the client program can bind the service and call the method from ibinder during IPC. Each aidl file can only define one interface, and can only be an interface declaration a

Greendao The storage of object data can be implemented with parcelable. 1. Greendao Greendao is an ORM solution that can help Android developers quickly map Java objects to a form in a SQLite database, and by using a simple object-oriented API, developers can store, update, delete, and query Java objects. 2. parcelable
