如何去除一个可点击对象的可生成字符串中的下划线？

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.

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;
}
@Override
public void onClick(View tv) {
Toast.makeText(MainActivity.this,clicked , Toast.LENGTH_SHORT).show();
}


@Override
public void updateDrawState(TextPaint ds) {// override updateDrawState
ds.setUnderlineText(false); // set to false to remove underline
}
}

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);
}
}

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
}
}

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);

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);

If you do not want any pre-applied attributes do not call super.updateDrawState(). On overriding updateDrawState(object:Textpaint) with help of object you can apply or call different functions present in Text Paint.

ANURAG RASTOGI's answer saved the day for me! I already have a formatted SpannableString on which I wanted to apply a ClickableSpan:

spannableString.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
// Do something...
}
// Prevent
// ds.setColor(ds.linkColor);
// ds.setUnderlineText(true);
// in: https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/text/style/ClickableSpan.java
// from executing.
@Override
public void updateDrawState(@NonNull TextPaint ds) {
// super.updateDrawState(ds);
}
},0, spannableString.length(), SPAN_EXCLUSIVE_EXCLUSIVE);

The updateDrawState overrides the updateDrawState in the ClickableSpan class in Android, and by not calling super.updateDrawState it will not get executed.

All text formatting already present in spannableString will be preserved.

Based on the answer of @Sai Gopi Me

in Kotlin:

val clickableSpan: ClickableSpan = object : ClickableSpan() {
override fun onClick(widget: View) {
// some action here
}
                

override fun updateDrawState(ds: TextPaint) {
super.updateDrawState(ds)
ds.isUnderlineText = false
}
}
}
