Extend to make a custom activity

Sample code

If you want to extend the CropImageActivity please be aware you will need to setup your CropImageView

• Add CropImageActivity into your AndroidManifest.xml

<activity android:name="com.canhub.cropper.CropImageActivity"
  android:theme="@style/Base.Theme.AppCompat"/> <!-- optional (needed if default theme has no action bar) -->

• Setup your CropImageView after call super.onCreate(savedInstanceState)

override fun onCreate(savedInstanceState: Bundle?) {
   super.onCreate(savedInstanceState)
   setCropImageView(binding.cropImageView)
}

Custom dialog for image source pick

When calling crop directly the library will prompt a dialog for the user choose between gallery or camera (If you keep both enable). We use the Android default AlertDialog for this. If you wanna customised it with your app theme you need to override the method showImageSourceDialog(..) when extending the activity (above)

override fun showImageSourceDialog(openSource: (Source) -> Unit) {
     super.showImageSourceDialog(openCamera)
}
