I would like to have a TextView
that is both selectable and linkified. When I do both I end up with selectable text but links can't be clicked.
EDIT:
I'll show the code to explain with what I struggle:
TextView textView = view.findViewById(R.id.mytext);
textView.setText("My text: +4412345678 Go to website: www.google.com Blah blah");
Linkify.addLinks(textView, Linkify.ALL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
textView.setTextIsSelectable(true);
}
Did you try to add this on your TextView xml code?
<TextView
...
android:autoLink="all"
android:textIsSelectable="true" />
I've tried it on my code and i can make a call/surf on web/mail and also select all text.
The autoLink
attribute has an annoying bug: if you click in your example on the phone number, then return back and click on the second url link - it will open the phone number again. This attribute works so bad with multiple links, that I have implemented my own class, here is the link on Github ClickableLinksTextView.java
In your example you can replace your TextView
class by my ClickableLinksTextView
class in the xml-layout and change the code like this:
ClickableLinksTextView textView = (ClickableLinksTextView)view.findViewById(R.id.mytext);
textView.setText("My text: +4412345678 Go to website: www.google.com Blah blah");
Linkify.addLinks(textView, Linkify.ALL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
textView.setMovementMethod(ArrowKeyMovementMethod.getInstance());
textView.setTextIsSelectable(true);
// the autoLink attribute must be removed, if you hasn't set it then ok, otherwise call textView.setAutoLink(0);
}
The original cause of the issue in your question is that the LinkMovementMethod
class and the textIsSelectable
attribute are not compatible at all, even Android OS developers admit this in the Android OS source code.
Do not change the movement method for text that support text selection as it would prevent an arbitrary cursor displacement.
If the text view is selectable, the only 2 correct movement method values are null
and ArrowKeyMovementMethod
. That's why I set ArrowKeyMovementMethod
explicitly in my example, because the Linkify.addLinks
sets an incorrect movement method and I should revert it.
As to the bug of the autoLink attribute, it is because android developers haven't copied link detection properly. You can look at the code example in the answer of @cheng yang, the code just takes the first link no matter how many of them you have.
The problem is in Android's TextView
. Calling Linkify.addLinks()
would not change autolinkmask in TextView
itself.
I think it's an Android bug that they check mAutoLinkMask.
So if you set android:autoLink
in xml
file, or call setAutoLinkMask()
to a non 0 value, it will work.
FYI, TextView
's source code:
if (touchIsFinished && mLinksClickable && mAutoLinkMask != 0 && textIsSelectable) {
// The LinkMovementMethod which should handle taps on links has not been installed
// on non editable text that support text selection.
// We reproduce its behavior here to open links for these.
ClickableSpan[] links = ((Spannable) mText).getSpans(getSelectionStart(),
getSelectionEnd(), ClickableSpan.class);
if (links.length > 0) {
links[0].onClick(this);
handled = true;
}
}
