使用“是/否”对话框拦截链接LinkMovementMethod

Question

I have a standard LinkMovementMethod established in my TextView to push a web Activity of some sort when the user touches a link. However, I want to establish a "do you want to see the link" dialog rather than taking the user straight to the webpage. I've tried overriding the touch methods but it all gets a little convoluted. A little help?

Answer 1

You can accomplish it in two ways:

• Create custom Spans : more complicated, but you can accomplish more customised text consisting of clickable parts (or bold, differently coloured etc). To know more, check out ClickableSpan and SpannableStringBuilder
• Extend LinkMovementMethod to accept custom click listener

In my opinion second solution is better in basic cases like yours. Here is how you can do it:

1. Copy this java class: InternalLinkMovementMethod to your project
2. Add set the link movement method of your TextView to this custom one, providing a click listener:

OnLinkClickedListener clickListener = new OnLinkClickedListener() {
    @Override
    public boolean onLinkClicked(String linkText) {
        // here you can handle your click, eg show the dialog
        // `linkText` is the text being clicked (the link)
        // return true if handled, false otherwise
    }
}

yourTextView.setMovementMethod(new InternalLinkMovementMethod(clickListener));
