Library created to enable easy to use, reflection free, lazy initialisation with auto destruction on lifecycle of data and view binders. You probably seen already similar approaches in some tutorials. I can not find ready to use lib like that.
Add it in root build.gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}and the dependency itself
dependencies {
implementation 'com.github.GrzegorzBobryk:ViewBindingDelegate:1.0.10'
}Remember to not call binder object from onDestroyView() event because it will cause recreation and memory leak.
You can find them in sample module. Here you have quick usage:
class ExampleFragment : Fragment(R.layout.fragment_example) {
//simple binding
private val binding by viewBinding(FragmentExampleBinding::bind)
//binding with setting up DataBinding variables
private val binding by viewBinding {
FragmentExampleBinding.bind(it).also { binding ->
binding.text = getString(R.string.example)
}
}
}You can also use safeSetAdapter to automatically clean adapter reference from fragment. Do not call it from pagers.
class ExampleFragment1 : Fragment(R.layout.fragment_example) {
private val binding by viewBinding(FragmentExampleBinding::bind)
private val adapter by lazy { ExampleAdapter(::handleExampleClick) }
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
//calling extension function
binding.list.safeSetAdapter(adapter)
adapter.submitList(list)
}
}
