Forcing onLayout on React Native view

问题:

I have a React Native View containing a Text field, and I'm using the onLayout prop to do some positional calculations which rely on the data it provides.

<View onLayout={this.calculateDimensions}>
  <Text>{this.props.content}</Text>
</View>

This works well, but there is a scenario where the content prop updates to a different string with the same character size. This results in the layout not changing and onLayout not triggering.

These positional calculations must occur each time the content prop updates.

Note: I am aware there are numerous ways to make the component update. Updating is not the same and laying out and sadly does not trigger onLayout.
