I have a Spannable Object
with a Clickable Object
set to it. When the Spannable String
is displayed in the TextView
it has blue text and a blue underline (indicating to the user that this Text is Clickable). My problem is how can I prevent appearing the blue underline in TextView
?

Use the below code and try
String mystring =" Hello";
SpannableString ss= new SpannableString(mystring);
ss.setSpan(new MyClickableSpan(mystring), 0, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
class MyClickableSpan extends ClickableSpan{// extend ClickableSpan
String clicked;
public MyClickableSpan(String string) {
super();
clicked = string;
}
public void onClick(View tv) {
Toast.makeText(MainActivity.this,clicked , Toast.LENGTH_SHORT).show();
}
public void updateDrawState(TextPaint ds) {// override updateDrawState
ds.setUnderlineText(false); // set to false to remove underline
}
}

This works for me. No need to create custom ClickableSpan
class. Just override updateDrawState(TextPaint ds)
.
SpannableString span = new SpannableString("Some text");
ClickableSpan clickSpan = new ClickableSpan() {
@Override
public void updateDrawState(TextPaint ds) {
ds.setColor(ds.linkColor); // you can use custom color
ds.setUnderlineText(false); // this remove the underline
}
@Override
public void onClick(View textView) {
// handle click event
}
};
span.setSpan(clickSpan, 5, span.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
yourTextView.setText(span);

Override updateDrawState method of ClickableSpan class
String mystring =" Hello";
SpannableString ss= new SpannableString(mystring);
ss.setSpan(new MyClickableSpan(mystring), 0, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
class MyClickableSpan extends ClickableSpan{// extend ClickableSpan
String clicked;
public MyClickableSpan(String string) {
// TODO Auto-generated constructor stub
super();
clicked =string;
}
public void onClick(View tv) {
Toast.makeText(MainActivity.this,clicked ,
Toast.LENGTH_SHORT).show();
}
public void updateDrawState(TextPaint ds) {// override updateDrawState
ds.setUnderlineText(false); // set to false to remove underline
}
For changing color of spannable String
SpannableString ss = new SpannableString("android Stack Overflow");
ForegroundColorSpan fcs=newForegroundColorSpan(Color.parseColor("#01579B"));
ss.setSpan(fcs, 8,13, Spannable.SPAN_INCLUSIVE_INCLUSIVE);

Raghunandan's answer works perfectly for me. Here is a pared-down version of it:
public abstract class NoUnderlineClickableSpan extends ClickableSpan {
public void updateDrawState(TextPaint ds) {
ds.setUnderlineText(false);
}
}
回答5:
spannableStringObject.toString();
Edit
SpannableString ss = getYourSpannableString();
UnderlineSpan[] uspans = ss.getSpans(0, ss.length(), UnderlineSpan.class);
for (UnderlineSpan us : uspans) {
ss.removeSpan(us);
}
Will remove all the UnderlineSpans from the Spannable.

Try the below code to remove underlined and clicked event on multiple words in textview :
String str="Angelina Clapped For Lester Kang";
Spannable span = Spannable.Factory.getInstance().newSpannable(str);
// 0 to 8 start and index of Angelina
span.setSpan(new ClickableSpan(str), 0, 8, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
// 21 to 32 start and index of Lester Kang
span.setSpan(new ClickableSpan(str), 21, 32, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textview.setText(span);
class ClickableSpan extends ClickableSpan{
String clicked;
public ClickableSpan (String string) {
super();
}
public void onClick(View v) {
Toast.makeText(MyActivity.this,""+((TextView)v).getText().toString(),Toast.LENGTH_SHORT).show();
}
public void updateDrawState(TextPaint ds) {
// override updateDrawState
ds.setUnderlineText(false); // set to false to remove underline
}
}

simplest way is
string1 = new SpannableString("By Tapping Register You Agree To The \nTerms And Conditions");
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View widget) {
Toast.makeText(getApplicationContext(),"clicked",Toast.LENGTH_SHORT).show();
}
@Override
public void updateDrawState(TextPaint ds) {
ds.setUnderlineText(false); // this line removes underline
}
};
text_terms.setMovementMethod(LinkMovementMethod.getInstance());
string1.setSpan(clickableSpan,37,string1.length(),0);
text_terms.setText(string1);
