|type|blockquote|depth|inlineStyleRanges|entityRanges|data|723136|unstyled|723137|new+SpannableString(textView.getText())应该能工作。|offset|length|style|CODE|723138|或者我可以在函数中使用SpannedString执行同样的任务吗？
|723139|723140|对不起，removeSpan()和setSpan()是Spannable接口上的方法，SpannedString不实现Spannable。|723141|entityMap^0|0|0|0|13|0|0|0|4|C|H|9|R|9|17|D|1N|9|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|-4|5|C|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|C|7|S|8|@$F|T|G|U|H|I]]|9|@]|A|$]]|$1|J|3|K|5|6|7|V|8|@]|9|@]|A|$]]|$1|L|3|-4|5|C|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|C|7|X|8|@$F|Y|G|Z|H|I]|$F|10|G|11|H|I]|$F|12|G|13|H|I]|$F|14|G|15|H|I]|$F|16|G|17|H|I]]|9|@]|A|$]]|$1|O|3|-4|5|C|7|18|8|@]|9|@]|A|$]]]|P|$]]

<code>new SpannableString(textView.getText())</code> should work.

Sorry, but <code>removeSpan()</code> and <code>setSpan()</code> are methods on the <code>Spannable</code> interface, and <code>SpannedString</code> does not implement <code>Spannable</code>.

blocks|key|3343527|text|如果在设置BufferType.SPANNABLE文本时指定了TextView，那么在获取文本时可以将其转换为Spannable。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3343528|myTextView.setText("hello",+TextView.BufferType.SPANNABLE);

If you specify <code>BufferType.SPANNABLE</code> when setting the <code>TextView</code>'s text, then when getting the text you can cast it to <code>Spannable</code>

<pre><code>myTextView.setText("hello", TextView.BufferType.SPANNABLE);
...
...
...
Spannable str = (Spannable) myTextView.getText();
</code></pre>

This should be the correct work around. Its late tho but someone might need it in the future 

<pre><code>private void stripUnderlines(TextView textView) {
 SpannableString s = new SpannableString(textView.getText());
 URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
 for (URLSpan span : spans) {
 int start = s.getSpanStart(span);
 int end = s.getSpanEnd(span);
 s.removeSpan(span);
 span = new URLSpanNoUnderline(span.getURL());
 s.setSpan(span, start, end, 0);
 }
 textView.setText(s);
 }



private class URLSpanNoUnderline extends URLSpan {
 public URLSpanNoUnderline(String url) {
 super(url);
 }

 @Override
 public void updateDrawState(TextPaint ds) {
 super.updateDrawState(ds);
 ds.setUnderlineText(false);
 }
}
</code></pre>

Unfortunately none of these worked for me but after fiddling around with all of your solutions I found something that worked. 

It will error casting the textView.getText() to Spannable unless you specify it as SPANNABLE

Also Notice from @CommonsWare's page:

Note that you do not want to call setText() on the TextView, thinking that you would be replacing the text with the modified version. You are modifying the TextView’s text in place in this fixTextView() method, and therefore setText() is not necessary. Worse, if you are using android:autoLink, setText() would cause Android go back through and add URLSpans again.

<pre><code>accountAddressTextView.setText(accountAddress, TextView.BufferType.SPANNABLE);

stripUnderlines(accountAddressTextView);

private void stripUnderlines(TextView textView) {
 Spannable entrySpan = (Spannable)textView.getText();
 URLSpan[] spans = entrySpan.getSpans(0, entrySpan.length(), URLSpan.class);

 for (URLSpan span: spans) {
 int start = entrySpan.getSpanStart(span);
 int end = entrySpan.getSpanEnd(span);
 entrySpan.removeSpan(span);
 span = new URLSpanNoUnderline(entrySpan.subSequence(start, end).toString());
 entrySpan.setSpan(span, start, end, 0);
 }
}

Hello I have set some text in a textview.

<pre><code>TextView tweet = (TextView) vi.findViewById(R.id.text);
tweet.setText(Html.fromHtml(sb.toString()));
</code></pre>

Then I need to convert the text of the <code>TextView</code> into <code>Spannble</code>. So I did this like:

<pre><code>Spannable s = (Spannable) tweet.getText();
</code></pre>

I need to convert it <code>Spannable</code> because I passed the <code>TextView</code> into a function:

<pre><code> private void stripUnderlines(TextView textView) {
 Spannable s = (Spannable) textView.getText();
 URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
 for (URLSpan span : spans) {
 int start = s.getSpanStart(span);
 int end = s.getSpanEnd(span);
 s.removeSpan(span);
 span = new URLSpanNoUnderline(span.getURL());
 s.setSpan(span, start, end, 0);
 }
 textView.setText(s);
 }

private class URLSpanNoUnderline extends URLSpan {
 public URLSpanNoUnderline(String url) {
 super(url);
 }

 @Override
 public void updateDrawState(TextPaint ds) {
 super.updateDrawState(ds);
 ds.setUnderlineText(false);
 }
 }
</code></pre>

This shows no error/warning. But throwing a Runtime Error:

<pre><code>java.lang.ClassCastException: android.text.SpannedString cannot be cast to android.text.Spannable
</code></pre>

How can I convert the SpannedStringt/text of the textview into Spannble? Or can I do the same task with SpannedString inside the function?
