react-native 怎么实现遮罩层

Answer 1

创建一个Animated.Value

[javascript] view plain copy
<Animated.View style={ styles.mask } >
</Animated.View>

<Animated.View style={[styles.tip , {transform: [{
translateY: this.state.offset.interpolate({
inputRange: [0, 1],
outputRange: [height, (height-aHeight -34)]
}),
}]
}]}>
lt;/Animated.View>
