View Binding vs Data Binding Gotchas

Do I still need View Binding if I have already enabled Data Binding in my Android project?

Let’s say you have a fragment layout as below, and you want to add a View Binding into your project.

<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:orientation="vertical"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent">  

    <TextView  android:id="@+id/textView"  
        android:layout_width="match_parent"  
        android:layout_height="wrap_content"  
        android:text="TextView" />  

</LinearLayout>

Enable View Binding

You enable this viewBinding in your build.gradle(module).

buildFeatures {  
    viewBinding true  
}

Then, you inflate the fragment layout in onCreateView()

override fun onCreateView(  
    inflater: LayoutInflater, container: ViewGroup?,  
  savedInstanceState: Bundle?  
): View? {  

  val binding = FragmentFirstBinding.inflate(inflater)  
  // access view in this fragment  
  val textView = binding.textview  
  return binding.root   
}
