How modify navigation & graph ?

[CMingTseng]

Dear Sir

Thank you for your article and code

https://medium.com/@artemsi93/navigation-for-nested-child-fragment-9da4318377ba

https://github.com/Artemake/android-nested-navigation/tree/main/app/src/main/res/navigation

Because the next generation is developed using compose

Use the route method in the nav part

The traditional xml description of graph using navigation

In fact, there will be bugs!!

fragment's android:name in XML

For example (android:name="com.learningwithmanos.nested_navigation_example.InitialFragment")

Because it is an XML string

Therefore, after changing/moving the packagename, it will not change together.

I'm looking for a way to make the graph of navigation all by code

I don’t know what you think?

hello there 👋

So in general the article's and the repo's focus, was to demonstrate how nested navigation can be achieved with the navigation component of Android with fragments.

Having said that, your question is not really clear.
Do you want to know how you can achieve the same, but in jetpack compose?

android:name="com.learningwithmanos.nested_navigation_example.InitialFragment"

I'm sorry for my unclear expression.

What I want to ask is when using Navigation

We need to write XML Navigation Graph

In XML, the part we need to "specify" the Fragment is the full name of the Fragment in the hard code String. For example, android:name="com.learningwithmanos.nested_navigation_example.InitialFragment" in your example

Because it is the hard code of XML String

So when you move the InitialFragment packagename (for example to idv.learning.withmanos.nested.navigation.example) or change its name (for example InitialFragment to DemoFragment)

In fact, the String of android:name in the Graph of XML Navigation will not be changed at the same time.

So the better thing is: "Dynamicly add the navigation map through code, no need to define the navigation map xml file"

I wonder if I can demonstrate "Dynamicly adding a navigation map through code"

Thanks

ah ok, now I get your question.
So when you rename or change a file's location, then the corresponding changes are not applied to the xml nav graph is what you are saying.

But how are you making these changes? For example let's try to change the name of the fragment:
Provided that you are in AndroidStudio, then you need to leverage the capabilities of AndroidStudio so that you can actually change the name of the Fragment, but also have these changes applied to the nav graph.
All you need to do is right click on the corresponding file that you want to change -> Refactor -> Rename and the changes will be applied in all the places that they should.

The same case should be when trying to move the file within the package. I am not sure what would happen if you would try to apply change to the package name itself though.
