TouchableOpacity

If you're looking for a more extensive and future-proof way to handle touch-based input, check out the Pressable API.

本组件用于封装视图,使其可以正确响应触摸操作。当按下的时候,封装的视图的不透明度会降低。

不透明度的变化是通过把子元素封装在一个Animated.View中来实现的,这个动画视图会被添加到视图层级中,少数情况下有可能会影响到布局。(译注:此组件与 TouchableHighlight 的区别在于并没有额外的颜色变化,更适于一般场景。)
