Android Bundle delivers simple data, object data

During the process of Android development, the process encounters data transfer between components and processes, and there are many kinds of data transfer, which is very convenient to use bundles.

Bundles can pass a variety of data, which is a map-like key-value data structure

The simple invocation is shown below

Bundle Bundle=new Bundle (); bundle.put*** (Key,value)

But sometimes we need to pass an object, which is to serialize the object using serializable first.

public class book implements serializable{

}

And then when you need to use that object to pass

Bundle bundle = new bundle ();

Bundle.putserializable ("book", book);

Where book is an object data

Remove data using

Book info = [book] bundle.getserializable ("book");
