I\'ve been using the android:autoLink
just fine for formatting links and such, but I need to use android:onClick
so I can\'t use that in this case.
Linkify is a great class, it hunts for complex patterns like URLs, phone numbers, etc and turns them into URLSpans. Rather than re-write the existing regular expressions I extended the URLSpan class and created a method to upgrade only the telephone URLSpans to a custom URLSpan with a confirmation dialog.
First my extended URLSpan class, ConfirmSpan:
class ConfirmSpan extends URLSpan {
AlertDialog dialog;
View mView;
public ConfirmSpan(URLSpan span) {
super(span.getURL());
}
@Override
public void onClick(View widget) {
mView = widget;
if(dialog == null) {
AlertDialog.Builder mBuilder = new AlertDialog.Builder(widget.getContext());
mBuilder.setMessage("Do you want to call: " + getURL().substring(4) + "?");
mBuilder.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
})
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
openURL();
}
});
dialog = mBuilder.create();
}
dialog.show();
}
public void openURL() {
super.onClick(mView);
}
}
Next the method to swap out the different span classes:
private void swapSpans(TextView textView) {
Spannable spannable = (Spannable) textView.getText();
URLSpan[] spans = textView.getUrls();
for(URLSpan span : spans) {
if(span.getURL().toString().startsWith("tel:")) {
spannable.setSpan(new ConfirmSpan(span), spannable.getSpanStart(span), spannable.getSpanEnd(span), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.removeSpan(span);
}
}
}
Finally all you need to do is create a TextView with the autoLink attribute:
android:autoLink="phone"
And remember to call the swapSpans()
method. Understand that I wrote this for fun, there may be other methods of doing this but I am unaware of them at the moment. Hope this helps!
android:clickable="true"
or setClickable(true)
to
your TextViews to make them clickable!To underline your TextView's text, you have to do something like:
final TextView text = (TextView) findViewById(R.id.text);
SpannableString string = new SpannableString("This is the uderlined text.");
string.setSpan(new UnderlineSpan(), 0, string.length(), 0);
text.setText(string);
This should work. Let me know about your progress.
With kotlin extension function (if you don't need the click effect as on a real link)
fun TextView.hyperlinkStyle() {
setText(
SpannableString(text).apply {
setSpan(
URLSpan(""),
0,
length,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
},
TextView.BufferType.SPANNABLE
)
}
How to use
yourTextView.hyperlinkStyle()
This is the shortest solution:
final CharSequence text = tv.getText();
final SpannableString spannableString = new SpannableString( text );
spannableString.setSpan(new URLSpan(""), 0, spannableString.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(spannableString, TextView.BufferType.SPANNABLE);
Sadly, the effect of clicking doesn't show up as being clicked on a real url link, but you can overcome it like so:
final CharSequence text = tv.getText();
final SpannableString notClickedString = new SpannableString(text);
notClickedString.setSpan(new URLSpan(""), 0, notClickedString.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(notClickedString, TextView.BufferType.SPANNABLE);
final SpannableString clickedString = new SpannableString(notClickedString);
clickedString.setSpan(new BackgroundColorSpan(Color.GRAY), 0, notClickedString.length(),
Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
tv.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(final View v, final MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
tv.setText(clickedString);
break;
case MotionEvent.ACTION_UP:
tv.setText(notClickedString, TextView.BufferType.SPANNABLE);
v.performClick();
break;
case MotionEvent.ACTION_CANCEL:
tv.setText(notClickedString, TextView.BufferType.SPANNABLE);
break;
}
return true;
}
});
Another solution is to use Html.fromHtml(...) , where the text inside has links tags ("") .

Have a better answer.This is what i did.
final SpannableString ss = new SpannableString("Click here to verify Benificiary");
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(false);
}
};
ss.setSpan(clickableSpan,0,ss.length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setHighlightColor(Color.BLUE);
You go anywhere you like when user clicks on the link through onclick method of ClickableSpan
