改变换行行为 [英] Altering line wrap behavior

问题描述

我可以在 TextViews 中使用 Spannable 来创建具有不同外观、下划线、删除线等的跨度.我该如何做同样的事情来改变换行行为?特别是，我不希望电子邮件地址在中间换行，我希望它表现得像一个词.

I can use Spannable in TextViews to create spans with different looks, underlines, strikethroughs and such. How can I do the same to alter line wrapping behavior? In particular, I don't want an email address to wrap in the middle, I want it to act like one word.

我尝试了 WrapTogetherSpan，但我无法得到它工作.貌似只有DynamicLayout使用，不能强制TextView使用DynamicLayout.

I tried WrapTogetherSpan, but I couldn't get it to work. It looks like it is only used by DynamicLayout, and I could not force the TextView to use DynamicLayout.

<TextView
  android:id="@+id/merchant_email_field"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:textSize="@dimen/account_setting_email"
  android:gravity="center"
  android:bufferType="spannable"
  android:maxLines="2"
  android:ellipsize="end"
  />

我如何设置可跨度:

WrapTogetherSpan TOGETHER_SPAN = new WrapTogetherSpan() {};
String collectedString = getString(R.string.email_sentence, userEmail);
int emailOffset = collectedString.indexOf(userEmail);
Spannable emailSpannable = Spannable.Factory.getInstance()
    .newSpannable(collectedString);
emailSpannable.setSpan(TOGETHER_SPAN, emailOffset,
    emailOffset + userEmail.length(),
    Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
textView.setText(emailSpannable)

推荐答案

不知道您是否找到了答案，但您可以使用 unicode 来帮助您.

Don't know if you have found an answer to it but you can use unicode to help you out.

有一个不间断的空格字符，所以你需要用这个字符(\u00A0)替换所有你想要牢不可破的空格

there is a non-break space character, so you will need to replace all the spaces you want to be unbreakable with this character (\u00A0)

举个例子

String text = "Hello World";
text.replace(' ', '\u00A0');
textView.setText(text);

顺便说一下，我一直在寻找 span 解决方案，但找不到，WrapTogetherSpan 只是一个接口，所以它不起作用...

by the way I've looked for a span solution and couldn't find one, WrapTogetherSpan is just an interface so it wouldn't work...

但是使用这种方法，如果您愿意，我相信您可以制作一个自定义的牢不可破的跨度.

but with this method I'm sure you could make a custom unbreakable span if you want.
