如何摆脱带有可点击对象的Spannable字符串中的下划线？

Question

我设置了Spannable Object Clickable Object。当Spannable String显示在TextView时，它有蓝色文本和蓝色下划线（向用户显示此文本是可点击的）。我的问题是如何防止在TextView中出现蓝色下划线？

Answer 1

使用以下代码并尝试

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

这对我有用。无需创建自定义ClickableSpan类。只需覆盖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);

Answer 3

覆盖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
}

用于更改spannable String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 4

Raghunandan的回答对我来说非常合适。这是它的简化版本：

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

Answer 5

  

<击> spannableStringObject.toString（）;

修改

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

将从Spannable中删除所有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);

Answer 8

ANURAG RASTOGI的回答为我节省了一天！我已经有一个格式化的Dim values() As String Using objReader As New System.IO.StreamReader(fileLocation) Do While Not objReader.EndOfStream values = objReader.ReadLine().Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries) For Each value As String In values value = value.Trim() If value.Length = 8 AndAlso value.All(Function(c) Char.IsDigit(c)) Then ListBox1.Items.Add(value) Exit For End If Next Loop End Using ，我想在其上应用一个SpannableString：

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); 会覆盖Android updateDrawState类中的updateDrawState，并且通过不调用ClickableSpan不会被执行。

super.updateDrawState中已经存在的所有文本格式将被保留。

Answer 9

如果您不希望任何预先应用的属性，请不要调用 super.updateDrawState（）。在 object 的帮助下覆盖updateDrawState（object：Textpaint）时，您可以应用或调用Text Paint中存在的不同函数。
