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 with background
property.
Example:
renderButton: function() {
return (
<TouchableNativeFeedback
onPress={this._onPressButton}
background={TouchableNativeFeedback.SelectableBackground()}>
<View style={{width: 150, height: 100, backgroundColor: 'red'}}>
<Text style={{margin: 30}}>Button</Text>
</View>
</TouchableNativeFeedback>
);
},

Methods
Reference
Props
background
Determines the type of background drawable that's going to be used to display feedback. It takes an object with type
property and extra data depending on the type
. It's recommended to use one of the static methods to generate that dictionary.
Type | Required |
---|---|
backgroundPropType | No |
useForeground
Set to true to add the ripple effect to the foreground of the view, instead of the background. This is useful if one of your child views has a background of its own, or you're e.g. displaying images, and you don't want the ripple to be covered by them.
Check TouchableNativeFeedback.canUseNativeForeground() first, as this is only available on Android 6.0 and above. If you try to use this on older versions you will get a warning and fallback to background.
