ViewBindingPropertyDelegate

Make work with Android View Binding simpler. The library do:

• managing ViewBinding lifecycle and clear reference to it to prevent memory leaks
• you don't need to keep nullable reference to Views or ViewBindings
• create ViewBinding lazy

The library has two variants: reflection and without it. They were divided in separate artifacts: viewbindingpropertydelegate and viewbindingpropertydelegate-noreflection. Prefer to use variant without reflection for better performance

IMPORTANT: Enable ViewBinding before use the library

Every Gradle module of your project where you need use ViewBinding must be configured properly. How to do that you can find in the official guide

Add library to a project

allprojects {
  repositories {
    mavenCentral()
  }
}

dependencies {
    implementation 'com.github.kirich1409:viewbindingpropertydelegate:1.5.3'
    
    // To use only without reflection variants of viewBinding
    implementation 'com.github.kirich1409:viewbindingpropertydelegate-noreflection:1.5.3'
}

Samples

class ProfileFragment : Fragment(R.layout.profile) {

    // Using reflection API under the hood and ViewBinding.bind
    private val viewBinding: ProfileBinding by viewBinding()

    // Using reflection API under the hood and ViewBinding.inflate
    private val viewBinding: ProfileBinding by viewBinding(createMethod = CreateMethod.INFLATE)

    // Without reflection
    private val viewBinding by viewBinding(ProfileBinding::bind)
}

class ProfileActivity : AppCompatActivity(R.layout.profile) {

    // Using reflection API under the hood
    private val viewBinding: ProfileBinding by viewBinding(R.id.container)

    // Without reflection
    private val viewBinding by viewBinding(ProfileBinding::bind, R.id.container)
}
