JarCastingBetterLinkMovementMethod
When android:autoLink="all" or Linkify.addLinks(textView, Linkify.ALL) is used to add links to web URLs, phone-numbers, map addresses or email addresses in a TextView, Android uses a class known as LinkMovementMethod for highlighting links when they're focused and dispatching an Intent when they're clicked.
BetterLinkMovementMethod improves over LinkMovementMethod, by fixing some of its flaws:
- No support for custom click listeners. For eg., phone numbers always show up in the dialer when clicked and there's no way to change that.
- Incorrect calculation of touch areas for links, resulting in ghost touch areas (video).
- Unreliable highlighting of links (video).
A detailed explanation of why (and when) you should use BetterLinkMovementMethod can be read on my blog: http://saket.me/better-url-handler-textview-android/
Usage
BetterLinkMovementMethod is designed to be a drop-in replacement for LinkMovementMethod:
dependencies {
implementation 'me.saket:better-link-movement-method:2.2.0'
}
val textView = findViewById(...)
Linkify.addLinks(textView, Linkify.ALL)
textView.movementMethod = BetterLinkMovementMethod.getInstance()
Click listeners can be registered by creating a unique instance of BetterLinkMovementMethod for each TextView:
textView.movementMethod = BetterLinkMovementMethod.newInstance().apply {
setOnLinkClickListener { textView, url ->
// Handle click or return false to let the framework handle this link.
true
}
setOnLinkLongClickListener { textView, url ->
// Handle long-click or return false to let the framework handle this link.
true
}
}
