如何在Android TextView上使用removeSpan（）？

Question

Pardon me if I'm asking a dumb question but I would like to know how to remove a span from text in my textview. This is how my span method looks like.

public CharSequence setTextStyleItalic(CharSequence text) {
    StyleSpan style = new StyleSpan(Typeface.ITALIC);
    SpannableString str = new SpannableString(text);
    str.setSpan(style, 0, text.length(), 0);
    return str;
}

and this is how i call it.

tvTitle.setText(setTextStyleItalic(tvTitle.getText()));

I would really like to know how to remove this italic span in java using removeSpan() please.

Answer 1

Get the text of the TextView and cast it to SpannableString then you can use the getSpans(int queryStart, int queryEnd, Class<T> kind) method to iterate over those spans and remove them

SpannableString ss=(SpannableString)txtView.getText();
ForegroundColorSpan[] spans=ss.getSpans(0, txtView.getText().length(), ForegroundColorSpan.class);
for(int i=0; i<spans.length; i++){
  ss.removeSpan(spans[i]);
}

Answer 2

First get text from your span using getSpans()

  removeTextSpan = tvTitle.getSpans(0, tvTitle.getText().length(),ForegroundColorSpan.class);
  for (int i = 0; i < removeTextSpan.length; i++) 
  tvTitle.removeSpan(removeTextSpan[i]);

i think this will help
