Parcelable, this word should be a stranger to you. An interface for serializing an object

Not clear can look at this blog: Intent the two methods of passing objects

-----------------------------------------------------------------------------

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 do the repetitive things.

So because Parcelable has the advantage of using it, we can't give up, what should we do?

Android Studio provides us with a plugin to simplify the process of implementing a parcelable interface to a class.

-----------------------------------------------------------------------------

Now learn how to use this plugin:

1, Android Studio open a project, click on the upper left corner File-->settings ... To set

2, choose Plug-in plugins, search parcel, if you have not downloaded this plugin, then the search box will show "Nothing to show." Click Browse to ....

3, then click on the blue font of the Browse bar, this time will appear as the interface, we just need to select Arcel on the left and then click on the Right green button "Install plugin" on it.

4, completed the above three steps, you can use the Parcelable Code generator plug-in

How to use it,

(1) Create a class file, the class name is to see what you need to customize the write, add the attributes you want

(2) shortcut key Alt+insert, will appear the following selection box, select Parcelable can

And then we see the code, is not much faster than we write manually
