ViewBindingPropertyDelegate

Make work with Android View Binding simpler. The library:

• manages ViewBinding lifecycle and clears the reference to it to prevent memory leaks
• eliminates the need to keep nullable references to Views or ViewBindings
• creates ViewBinding lazily

The library comes in two variants: with and without reflection. The artifacts are respectively: vbpd and vbpd-reflection. Prefer to use the one without reflection for better performance

IMPORTANT: Enable ViewBinding before using the library

Each Gradle module in your project where you need to use ViewBinding must be properly configured. Refer to the official guide on how to do that

Add the library to a project

allprojects {
  repositories {
    mavenCentral()
  }
}

dependencies {
    // recommended
    implementation("dev.androidbroadcast.vbpd:vbpd:2.0.2")
    
    // additional factories that use reflection under hood
    implementation("dev.androidbroadcast.vbpd:vbpd-reflection:2.0.2")
}

Samples

import javax.swing.text.View

class ProfileFragment : Fragment(R.layout.profile) {
   // RECOMMENDED 
   // no reflection API is used under the hood
   private val profileBinding: ProfileBinding by viewBinding(ProfileBinding::bind)

   override fun onViewCreated(view: View) {
       super.onViewCreate(view)
       with(profileBinding) {
          firstName.text = person.name
          lastName.text = person.surname
          email.text = person.email
       }
   }

   override fun onViewDestroyed() {
      super.onViewDestroyed()
      // profileBinding will be cleared after onViewDestroyed()
   }
}

Migration from 1.0

You can use 1.X and 2.X in the same project without replacing code

• Replace packages com.github.kirich1409.viewbindingpropertydelegate -> dev.androidbroadcast.vbpd
• Replace onViewDestroyed with moving code to proper lifecycle callback (Fragment.onViewDestroyed(), Activity.onDestroy(), etc.)
