TouchableNativeFeedback
A wrapper for making views respond properly to touches (Android only). On Android this component uses native state drawable to display touch Feedback. At the moment it only supports having a single View instance as a child node,as it's implemented by replacing that View with another instance of RCTView node with some additional properties set.
Background drawable of native Feedback touchable can be customized withbackground
property.
Example:
Props
backgroundbackgroundPropType
Determines the type of background drawable that's going to be used to display Feedback. It takes an object withtype
property and extra data depending on thetype
. It's recommended to use one of the static methods to generate that dictionary.
