【中文标题】Android Linkify.addLinks() 适用于一个 textview 而不是另一个【英文标题】：Android Linkify.addLinks() works for one textview and not the other one 【发布时间】：2020-04-18 15:16:01 【问题描述】：我有一个聊天实现，类似于我的应用中的 whatsapp。
在聊天中，我有一个接收者状态和一个发送者状态。
我面临的问题是，在发件人状态下，我发送的链接根本不可点击，尽管我对它们都执行了完全相同的代码。
这是我对待发件人视图持有者的方式 -
private void handleMessageForSender(Message item, TxtViewHolder txtViewHolder, String time, String msg)
txtViewHolder.getViewSender().setVisibility(View.VISIBLE);
txtViewHolder.getTxtChatTime().setText(time);
txtViewHolder.getTxtChatTime().setTextColor(context.getResources()
.getColor(R.color.color_black));
txtViewHolder.getTxtChatTime().setVisibility(View.VISIBLE);
txtViewHolder.getTxtChatSender().setTextColor(context.getResources()
.getColor(R.color.color_black));
boolean oneRowWithLink = false;
Matcher matcher = android.util.Patterns.WEB_URL.matcher(messageDetail.getMessage() != null && (item.getRecall() == null || !item.getRecall()) && messageDetail.getMessage().contains("http") ? messageDetail.getMessage() : "");
if (matcher.find())
oneRowWithLink = true;
String urlMessage = matcher.group(1);
LinkPreviewModel linkPreviewModel = linkPreviewModelHashMap.get(urlMessage);
if (linkPreviewModel != null)
txtViewHolder.getViewSender().setPadding(0, 0, 0, 4);
txtViewHolder.getLinkSentLayout().setVisibility(View.VISIBLE);
txtViewHolder.getLinkTitle().setText(linkPreviewModel.getTitle());
txtViewHolder.getLinkTitle().setTypeface(null, Typeface.BOLD);
txtViewHolder.getLinkMainUrl().setText(linkPreviewModel.getLinkMainUrl());
if (linkPreviewModel.getImageUrl() != null && linkPreviewModel.getImageUrl().length() > 0)
linkPreviewModelPositionsMap.put(item.getMid(), linkPreviewModel.getImageUrl());
MediaUtils.loadImageWithGlide(context, linkPreviewModel.getImageUrl(),
txtViewHolder.getLinkImageUrl(), R.drawable.ic_image_placeholder);
else
txtViewHolder.getLinkImageUrl().setVisibility(View.GONE);
if (linkPreviewModel.getDescription() != null && linkPreviewModel.getDescription().length() > 0)

displayRecallInfo(item, txtViewHolder);
else
txtViewHolder.getImgChatStatus().setVisibility(View.VISIBLE);
txtViewHolder.getSentRecallImage().setVisibility(View.GONE);
txtViewHolder.getTxtChatSender().setTypeface(Typeface.DEFAULT, Typeface.NORMAL);
txtViewHolder.getTxtChatSender().setTextKeepState(gethtmlChatMessageText(msg));

//set time layout new parameters
txtViewHolder.getSenderTimeLayout().measure(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT);
txtViewHolder.getImageStar().measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
if (defaultViewSendTimeWidth == -1)
defaultViewSendTimeWidth = txtViewHolder.getSenderTimeLayout().getMeasuredWidth();

我发现可能帮助我找到解决方案的线索是以下行 -
Linkify.addLinks(txtViewHolder.getTxtChatReceiver(), Linkify.WEB_URLS | Linkify.EMAIL_ADDRESSES | Linkify.PHONE_NUMBERS);
作为接收者，我在这条线上得到了正确的结果，而作为发送者，我得到了错误的结果——这意味着它不能将我的字符串作为 URL。
我在这里缺少什么吗？

【参考方案1】：已修复 - 我两次致电 getTxtChatReceiver，作为发送方和接收方
