Xmlserializer serialization XML for Android (write)

First, let's take a look at what is serializer. serializer is serialized, also known as serialization. It does not simply store the object in the memory, it allows us to transfer objects in the stream, so that the object can be transferred as the basic data.

Finally

Paste the main code:

Main. xml
<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> Android: Orientation = "vertical" <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "fill_parent" <br/> <textview <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "wrap_content" <br/> Android: id = "@ + ID/textview" <br/> </linearlayout> <br/>

Others are default.

We can see from the code that it is quite easy to generate xml using xmlserializer. The basic steps are similar to parsing XML. I won't talk much here. For more information, see API.
