Android ViewBinding Library
A simple library to simplify viewbinding delegation in your Android Application
Adding dependencies
Add this to your build.gradle:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}enable viewbinding in your app/build.gradle:
android {
....
buildFeatures {
viewBinding true
}
}Add the dependencies in your app/build.gradle:
dependencies {
....
implementation 'com.github.yogacp:android-viewbinding:x.x.x'
}How to use the library
Create your regular XML layout. For example, create activity_sample.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<TextView
android:id="@+id/tvTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:layout_marginBottom="16dp"/>
<Button
android:id="@+id/btnSample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textStyle="bold"/>
....
</LinearLayout>And use it in your Activity, just extend an binding variable that extend to your generated binding view and add by viewBinding() at the end:
class SampleActivity : AppCompatActivity() {
private val binding: ActivitySampleBinding by viewBinding()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding.tvTitle.text = getString(R.string.sample_title)
binding.btnSample.setOnClickListener {
Toast.makeText(this, "Sample Button Clicked", Toast.LENGTH_SHORT).show()
}
....
}
}And here if you want to use it in your Fragment. For example, you create a xml layout with name fragment_sample.xml:
class SampleFragment : Fragment(R.layout.fragment_sample) {
private val binding: FragmentSampleBinding by viewBinding()
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.tvFragmentTitle.text = getString(R.string.sample_fragment_title)
binding.btnFragmentSample.setOnClickListener {
Toast.makeText(context, "Sample Fragment Button Clicked", Toast.LENGTH_SHORT).show()
}
....
}
}And here if you want to use it in your BottomSheetDialogFragment. For example, you create a xml layout with name bottomsheet_sample.xml:
class SampleBottomSheetDialogFragment : BottomSheetDialogFragment() {
private val binding: BottomsheetSampleBinding by viewBinding()
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {
return binding.root //return root from binding delegation
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.tvFragmentTitle.text = getString(R.string.sample_fragment_title)
binding.btnClose.setOnClickListener {
Toast.makeText(context, "Sample BottomSheetDialog Button Clicked", Toast.LENGTH_SHORT).show()
}
....
}
}And here if you want to use it in your DialogFragment. For example, you create a xml layout with name dialog_sample.xml:
class SampleDialogFragment : DialogFragment() {
private val binding: DialogSampleBinding by viewBinding()
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {
return binding.root //return root from binding delegation
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.tvTitle.text = getString(R.string.sample_fragment_title)
binding.btnClose.setOnClickListener {
Toast.makeText(context, "Sample Dialog Button Clicked", Toast.LENGTH_SHORT).show()
}
....
}
}If you using proguard, add this line to your proguard-rules.pro.
