如何摆脱下划线的Spannable字符串一个可点击的对象？(How to get rid of th

我有一个Spannable Object具有Clickable Object设置它。 当Spannable String显示在TextView有蓝色文本和蓝色的下划线（指示，这文字可点击的用户）。 我的问题是我怎么能防止出现在蓝色下划线TextView ？

Answer 1:

使用下面的代码，并尝试

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
    }
}

Answer 2:

这对我的作品。 无需创建定制ClickableSpan类。 只是覆盖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);

Raghunandan的回答完全适用于我。 这里是它的一个削减的版本：

public abstract class NoUnderlineClickableSpan extends ClickableSpan {    
    public void updateDrawState(TextPaint ds) {
        ds.setUnderlineText(false);
    }
}

Answer 4:

重写ClickableSpan类的updateDrawState方法

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
}

为了改变spannable串的颜色

  SpannableString    ss = new SpannableString("android Stack Overflow");

  ForegroundColorSpan fcs=newForegroundColorSpan(Color.parseColor("#01579B"));
  ss.setSpan(fcs, 8,13, Spannable.SPAN_INCLUSIVE_INCLUSIVE);

Answer 5:

spannableStringObject.toString（）;

编辑

SpannableString ss = getYourSpannableString();
UnderlineSpan[] uspans = ss.getSpans(0, ss.length(), UnderlineSpan.class);
for (UnderlineSpan us : uspans) {
    ss.removeSpan(us);
}

将删除所有来自Spannable的UnderlineSpans。

Answer 6:

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
                    }
                }

Answer 7:

最简单的方法是

 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);
