我有被渲染基本的HTML，含2+链接一个TextView。 我需要捕捉的链接的点击，打开链接 - （不是在默认浏览器），在我自己的内部的WebView
处理链接呈现最常用的方法似乎是这样的：
String str_links = "<a href='http://google.com'>Google</a><br /><a href='http://facebook.com'>Facebook</a>";
text_view.setLinksClickable(true);
text_view.setMovementMethod(LinkMovementMethod.getInstance());
text_view.setText( Html.fromHtml( str_links ) );
然而，这将导致链接中默认的内部Web浏览器打开（显示“操作完成使用...”对话框）。
我试图实现onClickListener，链接被点击时正常被触发，但我不知道如何确定点击了哪个环节？
text_view.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
// what now...?
}
});
另外，我试图创建一个自定义LinkMovementMethod类和实施的onTouchEvent ...
public boolean onTouchEvent(TextView widget, Spannable text, MotionEvent event) {
String url = text.toString();
// this doesn't work because the text is not necessarily a URL, or even a single link...
// eg, I don't know how to extract the clicked link from the greater paragraph of text
return false;
}
想法？
实施例的解决方案
我想出了一个解决方案 ，它解析链接了一个HTML字符串，并让他们点击，然后让你的网址作出反应。
Answer 1:
基于另一种答案 ，这里是一个函数setTextViewHTML（）的解析链接了HTML字符串，使他们点击，然后让你的网址作出反应。
protected void makeLinkClickable(SpannableStringBuilder strBuilder, final URLSpan span)
{
int start = strBuilder.getSpanStart(span);
int end = strBuilder.getSpanEnd(span);
int flags = strBuilder.getSpanFlags(span);
ClickableSpan clickable = new ClickableSpan() {
public void onClick(View view) {
// Do something with span.getURL() to handle the link click...
}
};
strBuilder.setSpan(clickable, start, end, flags);
strBuilder.removeSpan(span);
}
protected void setTextViewHTML(TextView text, String html)
{
CharSequence sequence = Html.fromHtml(html);
SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence);
URLSpan[] urls = strBuilder.getSpans(0, sequence.length(), URLSpan.class);
for(URLSpan span : urls) {
makeLinkClickable(strBuilder, span);
}
text.setText(strBuilder);
text.setMovementMethod(LinkMovementMethod.getInstance());
}
Answer 2:
这可以通过使用Spannable String.What你真的想这样做（业务需求）是有点不清楚我，所以下面的代码不会给出确切的答案，您的情况，但我零用肯定，它将给你一些想法和简单地加以解决您将能够基于下面的代码来解决你的问题。
当你这样做，我也越来越通过HTTP响应一些数据，我已经在我的情况下，增加了部分附加下划线的文字“更多”，这下划线的文字将打开点击event.Hope Web浏览器，这将帮助你。
TextView decription = (TextView)convertView.findViewById(R.id.library_rss_expan_chaild_des_textView);
String dec=d.get_description()+"<a href='"+d.get_link()+"'><u>more</u></a>";
CharSequence sequence = Html.fromHtml(dec);
SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence);
UnderlineSpan[] underlines = strBuilder.getSpans(0, 10, UnderlineSpan.class);
for(UnderlineSpan span : underlines) {
int start = strBuilder.getSpanStart(span);
int end = strBuilder.getSpanEnd(span);
int flags = strBuilder.getSpanFlags(span);
ClickableSpan myActivityLauncher = new ClickableSpan() {
public void onClick(View view) {
Log.e(TAG, "on click");
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(d.get_link()));
mContext.startActivity(intent);
}
};
strBuilder.setSpan(myActivityLauncher, start, end, flags);
}
decription.setText(strBuilder);
decription.setLinksClickable(true);
decription.setMovementMethod(LinkMovementMethod.getInstance());
Answer 3:
你做如下：
text_view.setMovementMethod(LinkMovementMethod.getInstance());
text_view.setText( Html.fromHtml( str_links ) );
你按相反的顺序尝试如下图所示？
text_view.setText( Html.fromHtml( str_links ) );
text_view.setMovementMethod(LinkMovementMethod.getInstance());
而不：
text_view.setLinksClickable(true);
Answer 4:
我有同样的问题，但大量的文字有几个链接和电子邮件混合。 我觉得用“自动链接”是做一个更容易和更清洁的方式：
text_view.setText( Html.fromHtml( str_links ) );
text_view.setLinksClickable(true);
text_view.setAutoLinkMask(Linkify.ALL); //to open links
如果只有其中一个可以设置Linkify.EMAIL_ADDRESSES或Linkify.WEB_URLS要使用或从XML布局设置
android:linksClickable="true"
android:autoLink="web|email"
可用的选项有：无，Web，电子邮件，电话，地图，所有

我实现了一个小班与帮助，您可以处理的TextView本身长的点击和水龙头在TextView的链接。
布局
TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="all"/>

public class TextViewClickMovement extends LinkMovementMethod {

private Spannable mBuffer;
public enum LinkType {
/** Indicates that phone link was clicked */

/** Identifies that URL was clicked */
WEB_URL,
/** Identifies that Email Address was clicked */
EMAIL_ADDRESS,
/** Indicates that none of above mentioned were clicked */
NONE
}
/**

public interface OnTextViewClickMovementListener {
/**

void onLinkClicked(final String linkText, final LinkType linkType);

void onLongClick(final String text);
}
public TextViewClickMovement(final OnTextViewClickMovementListener listener, final Context context) {
mListener = listener;

}
@Override
public boolean onTouchEvent(final TextView widget, final Spannable buffer, final MotionEvent event) {
mWidget = widget;
mBuffer = buffer;
mGestureDetector.onTouchEvent(event);
return false;
}
/**

Layout layout = widget.getLayout();
int line = layout.getLineForVertical(y);
int off = layout.getOffsetForHorizontal(line, x);
ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);
if (link.length != 0) {
return buffer.subSequence(buffer.getSpanStart(link[0]),
buffer.getSpanEnd(link[0])).toString();
}
return "";
}
}
}
用法
String str_links = "<a href='http://google.com'>Google</a><br /><a href='http://facebook.com'>Facebook</a>";
text_view.setText( Html.fromHtml( str_links ) );
text_view.setMovementMethod(new TextViewClickMovement(this, context));

Answer 6:
一种方法更清洁，更好的解决方案，使用本机的Linkify库 。
例：
Linkify.addLinks(mTextView, Linkify.ALL);
Answer 7:
林只使用TextView的，而对于URL集跨度和处理点击。
我觉得很优雅的解决方案在这里，没有linkify - 照我知道我要linkify该字符串的一部分
处理TextView的链接点击在我的Android应用
在科特林：
fun linkify(view: TextView, url: String, context: Context) {
val text = view.text
val string = text.toString()
val span = ClickSpan(object : ClickSpan.OnClickListener {
override fun onClick() {
// handle your click
}
})
val start = string.indexOf(url)
val end = start + url.length
if (start == -1) return
if (text is Spannable) {
text.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
text.setSpan(ForegroundColorSpan(ContextCompat.getColor(context, R.color.orange)),
start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
} else {
val s = SpannableString.valueOf(text)
s.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
s.setSpan(ForegroundColorSpan(ContextCompat.getColor(context, R.color.orange)),
start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
view.text = s
}
val m = view.movementMethod
if (m == null || m !is LinkMovementMethod) {
view.movementMethod = LinkMovementMethod.getInstance()
}
}
class ClickSpan(private val mListener: OnClickListener) : ClickableSpan() {
override fun onClick(widget: View) {
mListener.onClick()
}
interface OnClickListener {
fun onClick()
}
}
及用量：linkify（yourTextView，urlString，上下文）
