ViewDataBinding extension to provide a more readable api for setting data into a binding object

_ViewDataBinding.bindData() extension gist.md

• Define an extension function on ViewDataBinding to provide a readable api for setting data into a binding object
• Usage is equivalent to use .apply{} but is more explicit about the desried usage

Extensions.kt

inline fun <T : ViewDataBinding> T.bindData(block: T.() -> Unit): T { block(); return this }

MainActivity.kt

// Use the extension function to set the data into the binding object in a very readable way
//
DataBindingUtil.setContentView<ActivityMainBinding>(this, R.layout.activity_main).bindData {
  message = "hello"
  number = 5
}

// Essentially equivalent to this, but possibly more readable
//
DataBindingUtil.setContentView<ActivityMainBinding>(this, R.layout.activity_main).apply {
  message = "hello"
  number = 5
}
