serializable interface

Chapter 5 data-centric-Data Access (3), Chapter 5 Access5.1.3 free operation-serialization and deserialization In Android development, apart from common text and XML files, data is often transmitted or accessed through serialization and

Use of the parcelable interface in Android Development For Android, the transmission of complex types is mainly to convert their classes into basic byte arrays, and data passing between activities is implemented through intent. Android

Directory[TOC]One, node flow and processing sulfur 1.1 node stream Also known as low-level flow , can be from or to a specific place (node read and write data) 1.2 Processing Flow Also known as an advanced stream , data is

I. The concept of serialization and deserialization　　The process of converting an object to a sequence of bytes is called serialization of an object .　　The process of reverting a sequence of bytes to an object is called deserialization of the object

41. What is the use of A.hashcode ()? What is the relationship with A.equals (b)?The Hashcode () method corresponds to the hash value of the integer type of the object. It is often used for hash-based collection classes such as Hashtable, HashMap,

Object FlowThe ObjectInputStream ObjectOutputStream class is a subclass of InputStream and OutputStream, respectively, and the object output stream uses the WriteObject (object obj) method, Writes an object, obj, to a file, using ReadObject () to

1. parcelable InterfaceInterface for classes whose instances can is written to and restored from a Parcel. Classes implementing the Parcelable interface must also has a static field called CREATOR, which is an object Implementin G The

When two processes are communicating remotely, each other can send various types of data. Regardless of the type of data, it is transmitted over the network in the form of a binary sequence. The sender needs to convert the Java object to a sequence

For Android, the transfer of complex types, mainly the conversion of their own classes to the underlying byte array, the activity between the data passed through intent implementation. There are two main ways to implement an serializable interface,

File I/O: file stream → serialization ★File streamFile operations are the simplest, most direct, and easiest way to think, the file operation we are talking about is not just writing data directly to a local file using

1. parcelableInterface Interface for classes whose instances can be written to and restored from a parcel. Classes implementing the parcelable interface must also have a static field called Creator, which is an object implementing the parcelable.

1. What is intent?   Intent refers to the view, which is the carrier for communication between different components in Android applications. When Android needs to connect different components during runtime, it usually needs to be implemented by

Android uses putExtra to transmit data. Android putextra When data is transmitted through intent, use the following code to report an error: hMap map=(Map) parent.getItemAtPosition(position);intent.putExtra("userInfoMap", map); However, the

1. parcelableInterface Interface for classes whose instances can be written to and restored from a parcel. Classes implementing the parcelable interface must also have a static field called Creator, which is an object implementing the parcelable.

Activity can jump and pass data through intent and bundles, data types that can be passed include basic data types, A string and an object that implements the Parcelable interface or serializable interface (file implements the Serializable interface)
