ViewBindingEx

ViewBinding with Kotlin Property Delegate and Lifecycle, no memory leak

Usage

1. Add maven central to your project

    repositories {
           ...
           mavenCentral()
           ...
    }
   

2. Add the dependency in your App module

    dependencies {
         implementation("cn.chitanda:viewbindingex:1.2.0")
    }
   

3. Activity

   class MainActivity : AppCompatActivity() {
   
       private  val binding by viewBinding(ActivityMainBinding::inflate)
   
       override fun onCreate(savedInstanceState: Bundle?) {
           setContentView(binding.root)
       }
   }
   

   Fragment or DialogFragment

   • Use ViewBinding.inflate()

     class HomeFragment : Fragment() {
     	private val binding by viewBinding { FragmentHomeBinding.inflate(layoutInflater) }
       private val viewModel by viewModels<HomeViewModel>()
      	
       override fun onCreateView(
          inflater: LayoutInflater,
          container: ViewGroup?,
          savedInstanceState: Bundle?): View {
          return binding.root
      	}
     
      	override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
          super.onViewCreated(view, savedInstanceState)
          binding.textHome.text = "hello world"
      	}
       
     }
     

   • Use ViewBinding.bind()

      class HomeFragment : Fragment(R.layout.fragment_home) {
     
     	private val binding by viewBinding (FragmentHomeBinding::bind)
     
     	override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
          super.onViewCreated(view, savedInstanceState)
          binding.button.setOnClickListener {
              HomeDialog().show(childFragmentManager,"dialog")
          }
       }
       
     }
