How can I specify allowable word break locations for long words?

Question

Let's say I want to add the word 'supercalifragilisticexpialidocious' to a TextView. How can I specify at what points Android may break up the word when it wraps it across multiple lines?

As an example, I only want Android to break the word at the locations specified by a hyphen as follows:

su-per-cal-i-frag-il-is-tic-ex-pi-al-i-do-cious

In this case, Android might display the word as:

supercalifrag-
ilisticexpial-
idocious

Answer 1

Soft Hyphen to the rescue! https://en.wikipedia.org/wiki/Soft_hyphen

First, you must set this property on a TextView:

android:hyphenationFrequency="normal"

Then you use the Soft Hypen character inside your strings:

Like so:

supercalifrag­ilisticexpial­idocious

Answer 2

扩展TextView并实现此行为 - 没有内置方法。
