Today, I encountered a problem in my android experiment. It took more than one hour to locate the problem and solve it.
This problem is relatively hidden and will waste a lot of time if you don't know it.
First look at the Code:
In newslistactivity.
When data is transmitted between activities, in order to avoid the trouble, some values are often encapsulated into objects, and then the entire object is passed over. The parcelable interface and the serializable interface can be implemented when
If you do not want to think about this problem, Google it. Find an article about serialization. Many people have explained this question: hibernate has a second-level cache, And the cache writes the object to the hard disk, so it must be
I believe that everyone in the process of Android development will always encounter in the middle of the activity to pass data, of course, encountered the need to pass the object in the intent of the situation is also unavoidable, so I took a bit of
In this tutorial we build a Java project to experience the use of serialization serializable, the principle of serialization, and the customization of serialization see my other blog (Java advanced---->serializable serialized source code
Android master path: Serializable and Parcelable, two methods of Intent passing objects in Android
In Android, two methods are passed: Serializable and Parcelable.
Serializable is supported by J2SE. Parcelable is unique to Android.
Use Cases and
Today, when I was writing a Java program, I found this warning prompt, so I Googled it. The answer is as follows:
If a serializable class does not explicitly declare a serialversionuid, then the serialization runtime will calculate a default
From: http://wang09si.blog.163.com/blog/static/170171804201373195046397/The first thing to understand is, what is serialization?We often see an entity class implement the Serializable interface, and this usage is serialization. The goal is to save
With intent, there are two ways to deliver Java objects between activity in an Android project: One passed object implements the serializable interface, and the other is the Parcelable interface that the passed object implements. This blog
