Learn about parcelable, we have the largest and most updated parcelable information on alibabacloud.com
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 void writeToParcel (Parceldest, intflags) meth

WhyWhy should I understand serialization? --When doing Android development, you cannot pass the object reference to activities or fragments, we need to put these objects into a intent or bundle, and then pass them on.WhatWhat is serialization-serialization, which represents the transformation of an object into a state that can be stored or transmitted. The serialized object can be transferred on the network or stored locally.HowHow do I transfer objects by serialization?Android Intent if you wan
Use Intent to transfer Java objects between activities in Android projects -- Implement Parcelable InterfaceUsing Intent to implement Java object transfer between activities in Android projects, there are two ways: one is the passed object implements the Serializable interface; the other is the passed object implements the Parcelable interface, this blog summarizes how to implement Java object transfer when

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.2. UseSerializable'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 Android Parcelable
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, while
One of the places that Parcelable uses is to pass a custom, more complex object between processes, and parcelable to write down his own point of view.An object, such as a custom class named cartoon, is passed to the other activity by one activity, and this time the parcelable is used. First, we'll build a bean. PackageCom.example.sendobjfromactivity.bean;ImportAn
In the process of Android development, it is recommended to use parcelable instead of seralizable for object serialization because the parceable is relatively efficient.In this way, for a large number of objects in Android, handwriting implementation of the cost of parcelable, it is relatively high. The landlord on GitHub found a parcelable for Intelij and Androi
The purpose of the serialization persist the object, save the object's byte sequence to the local file, to pass the object in the network by serializing the object, pass the object between processes through serialization, and Pass the complex custom class object in intent. The Parcelable interface needs to be implemented. Two. Methods for implementing serialization and comparison of advantages and disadvantages 1. Implement the Serializable int
From http://www.jiaojingkuan.com/archives/544. The explanation is thorough. Thanks The serialization of custom objects in Android has two options: parcelable and serializable. I. serialization reason: 1. Permanently Save the object and save the object's byte sequence to a local file;2. Passing objects in the network by serializing objects;3. objects are passed between processes through serialization. 2. for which to choose, refer to the following pr
Serialization method of custom objects in Android: Implements parcelable Implements serializable. I. serialization reason: Permanently Save the object and save the object's byte sequence to a local file; Passing objects in the network by serializing objects; Objects are passed through serialization between processes. 2. for which to choose, refer to the following principles: When using memory, p
values can be of any type, or even interfaces generated by other aidl. The import statements are not required for the basic data types (INT, long, Char, Boolean, etc.), string, and charsequence of the Java programming language. If you want to use other aidl Interface Types in aidl, You need to import them, even in the same package structure. Aidl allows passing classes that implement the parcelable interface. Import is required. Note that for non-bas
This assumes that we are already using parcelable to serialize an object ~ ~Then we will find that parcelable is a bit complicated to use, because we have to make a few of our own methods, and when the properties of the class is more, we will be uncomfortable, but also pay attention to not write the wrong attribute name, but also pay attention to write the type of property, but also spend a lot of time to d

First, Introduction1.Parcelable is an interface that enables serialization.2. The role of serialization is reflected in: You can use intent to pass data, or you can build a process to pass data (IPC).3.Parcelable when used, there is a parameter type: Parcel; it is like a container, when serialized, the data is passed in. When deserializing, the data is then fetched.4.Pa
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 parcelable is an interface used in And
