This project is an example of a Beagle Databinding adapter. This has the purpose of decrease the learning curve of Beagle declarative views, offer all support for Beagle developing that Android Studio has for DataBinding such layout previews, etc.
With this we can develop a simple xml view and transform it in a Beagle view struct:
Then for a simple example we have this xml normal view:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<layout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="@+id/test1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/test2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:layout_alignBottom="@+id/test1"/>
</RelativeLayout>
</layout>Once we've created that we can generate our DataBinding class for it:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val binding: ActivityMainBinding = DataBindingUtil.inflate(layoutInflater, R.layout.activity_main, null, false)
...
}Then now we can transform our ActivityMainBinding in a Beagle view struct using toBeagle() extension function
...
val beagleView = binding.toBeagle()
/**
Screen(
child = Container(children = listOf(
Text(text = "Hello World!"),
Text(text = "Hello World!")
))
)
**/
...For a next step I see the creation of native Beagle custom views to use in xml files to bind Screen types easier, and expand this interpreter to support Compose in future.
