react native - How to have Ellipsis effect on Text

Question

I'm having a long text in my app and I need to truncate it and add three dots to the end.

How can I do that in React Native Text element?

Thanks

Answer 1

Use the numberOfLines parameter on a Text component:

<Text numberOfLines={1}>long long long long text<Text>

Will produce:

long long long…

(Assuming you have short width container.)

Use the ellipsizeMode parameter to move the ellipsis to the head or middle. tail is the default value.

<Text numberOfLines={1} ellipsizeMode='head'>long long long long text<Text>

Will produce:

…long long text

NOTE: The Text component should also include style={{ flex: 1 }} when the ellipsis needs to be applied relative to the size of its container. Useful for row layouts, etc.
