Android TextView格式多个单词

概述原始字符串：Lorem##ipsum##dolar##sit##atem.Loremipsumdolar坐##atem##.格式化后：Lorem#ipsumdolar#sitatem.Loremipsumdolar坐#atem.但只有最后一个有我想要的Formating.见下图.码privatevoidformat(){CharSequencetext=editContent.getText

原始字符串：

Lorem ## ipsum ## dolar ## sit ## atem. Lorem ipsum dolar坐## atem ##.

格式化后：

Lorem #ipsum dolar #sit atem. Lorem ipsum dolar坐#atem.

但只有最后一个有我想要的Formating.见下图.

码

private voID format() {    CharSequence text = editContent.getText();    MovementMethod movementMethod = editContent.getMovementMethod();    if ((movementMethod == null) || !(movementMethod instanceof linkMovementMethod))    {        editContent.setMovementMethod(linkMovementMethod.getInstance());    }    text = setSpanBetweenTokens(text, "##", new ForegroundcolorSpan(0xFF0099FF), new Underlinespan(), new ClickableSpan() {        @OverrIDe        public voID onClick(VIEw Widget) {            Toast.makeText(getApplicationContext(), "click", Toast.LENGTH_SHORT).show();        }    });    editContent.setText(text);}private static CharSequence setSpanBetweenTokens(CharSequence text, String token, CharacterStyle... characterStyle) {    int tokenLen = token.length();    int start = text.toString().indexOf(token) + 1;    int end = text.toString().indexOf(token, start);    while (start > -1 && end > -1)    {        SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(text);        for (CharacterStyle c : characterStyle) {            spannableStringBuilder.setSpan(c, start, end, 0);        }        spannableStringBuilder.delete(end, end + tokenLen);        spannableStringBuilder.delete(start - 1, start);        text = spannableStringBuilder;        start = text.toString().indexOf(token) + 1;        end = text.toString().indexOf(token, start);    }    return text;}

我的最终解决方案

private voID format() {    CharSequence text = editContent.getText();    MovementMethod movementMethod = editContent.getMovementMethod();    if ((movementMethod == null) || !(movementMethod instanceof linkMovementMethod))    {        editContent.setMovementMethod(linkMovementMethod.getInstance());    }    text = setSpanBetweenTokens(text, "##");    editContent.setText(text);}private static CharSequence setSpanBetweenTokens(CharSequence text, String token) {    int tokenLen = token.length();    int start = text.toString().indexOf(token) + 1;    int end = text.toString().indexOf(token, start);    while (start > -1 && end > -1)    {        SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(text);        spannableStringBuilder.setSpan(new ForegroundcolorSpan(0xFF0099FF), start, end, 0);        spannableStringBuilder.setSpan(new Underlinespan(), start, end, 0);        spannableStringBuilder.setSpan(new ClickableSpan() {            @OverrIDe            public voID onClick(VIEw Widget) {                Log.d("DEBUG", "Click");            }        }, start, end, 0);        spannableStringBuilder.delete(end, end + tokenLen);        spannableStringBuilder.delete(start - 1, start);        text = spannableStringBuilder;        start = text.toString().indexOf(token) + 1;        end = text.toString().indexOf(token, start);    }    return text;}

解决方法:

为每个跨度传递不同的对象：

spannableStringBuilder.setSpan(c, start, end, 0);

您为每个跨度传递相同的对象：

new ForegroundcolorSpan(0xFF0099FF)

当span对象存在于spannableStringBuilder中时,它仅更改边界,而不是添加新的跨度.
