The binder mechanism implements the IPC and shared memory in different ways, and it takes aValue CopyThe way, the process of passing through the entity follows the Parcelable protocol, the BP side is responsible for writing to the parcel, the BN side is responsible for reading from the parcel restore, the order is agreed by both parties. Prototypes are as follows,the bp/bn end received in factare just clones of each other.。 Aidl (Android Interface Def

When you use intent to pass object data, you can use both intent.putserializable (Key,object) and Intent.putparcelable (Key, Object) methods. The object type to be passed must implement the Serializable interface or the Parcelable interface. Here are two ways to achieve this.Implement Serializable interface mode:public class Person implements Serializable {private string Name;public string GetName () {return name;} public void SetName (String name) {t

. -------in addition,the blog "yet another post on Serializable vs parcelable" when comparing Serializable and parcel refer to the following two-point data forReferenceunderstand that the actual use of each has a different1. After using serializable and parcel to transfer the same objects, all converted to byte[], parcel is probably 20 times times the serializable. 2. But the official recommendation is to use parcel, which is about 10 times times the

onsaveinstantcestate method, below to see what this method actually did: (You Mei's, how is the onsaveinstantcestate method?!) Khan Σ (° °| | |) ︴, it's almost there.)Take a look at the source code in activity:protected void Onsaveinstancestate (Bundle outstate) { outstate.putbundle (Window_hierarchy_tag, Mwindow.savehierarchystate ()); Parcelable p = mfragments.saveallstate (); if (P! = null) { outstate.putparcelable

Today, there is a very strange problem, confusing packaging caused by, so far do not understand why. The main phenomenon is an implementation of the Parcelable Userbean, the data member contains a Usertag object, the latter also implements the parcel interface, and then uses the JSON and the server to pass the value. When the label is not set, everything OK, as long as the setting of the label, will be error, errors can only be targeted to the convers

classes based on api interfaces. This plug-in automates this process and is ready for use. 4. Android Parcelable Code Generator There are two serialization methods in Android: Serializable interface and Parcelable interface. However, Parcelable is recommended in Android, but this method is more complicated than Serializable, with this plug-in, everything will

OrmLite can help us operate databases without having to write SQL statements by ourselves, and set it in the same way as using Sqlite. It is a relational data, what I like most is that it helps me determine whether data table items are updated or created, and does not need to write a large number of SQL statements to determine, the following describes its usage documents and some basic notes: Official Website: http://ormlite.com/ JavaDOC address: http://ormlite.com/javadoc/ormlite-android/ Devel

sum up, the entire UI update mechanism is actually a simple implementation of the Android message system model. At this point, we have finished updating the UI. As a supplement, let's take a thorough look at the entire messaging system model from the source code. 4. Excellent solution Here, we will analyze the source code to understand the specific implementation of each part, and then integrate it with the content mentioned above, so that we can gain a deep understanding of the specific imple

interface, which automates the process and uses it quickly.4. Android parcelable Code GeneratorThere are two ways to serialize in Android, which is to implement the Serializable interface and the Parcelable interface, but it is recommended to use parcelable in Android, but this is more cumbersome than the serializable approach.

Public boolean isChecked () (Translator's note: select or not) Public void onRestoreInstanceState (Parcelable state) Allows the view to be re-applied. Previously, onSaveInstanceState () was used to generate an internal state. This function never calls an empty state. Parameters The state returns the status that was previously saved by calling onSaveInstanceState. Public
