//创建一个 SpannableString对象
SpannableString sp = new SpannableString("这句话中有链接,有高亮显示，这样，或者这样，还有斜体.");
//设置超链接
sp.setSpan(new URLSpan("http://www.abc.com"), 5, 7, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置高亮样式一
sp.setSpan(new BackgroundColorSpan(Color.RED), 17 ,19,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置高亮样式二
sp.setSpan(new ForegroundColorSpan(Color.YELLOW),20,24,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
//设置斜体
sp.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 27, 29, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
//SpannableString对象设置给TextView
myTextView.setText(sp);
设置TextView可点击
myTextView.setMovementMethod(LinkMovementMethod.getInstance());
}
}

试试这两个方法

TextView location = (TextView) findViewById(R.id.location);
location.setMovementMethod(LinkMovementMethod.getInstance());
Spannable spans = (Spannable) location.getText();
ClickableSpan clickSpan = new ClickableSpan() {

@Override
public void onClick(View widget)
{
//put whatever you like here, below is an example
AlertDialog.Builder builder = new Builder(MainActivity.this);
builder.setTitle("Location clicked");
AlertDialog dialog = builder.create();
dialog.show();
}
};
spans.setSpan(clickSpan, 0, spans.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

TextView t3 = (TextView) findViewById(R.id.text3);
t3.setText(
Html.fromHtml(
"<b>text3:</b> Text with a " +
"<a href="http://www.google.com">link</a> " +
"created in the Java source code using HTML."));
t3.setMovementMethod(LinkMovementMethod.getInstance());

TextView textView = (TextView) findViewById(R.id.TextBox);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setText(Html.fromHtml(strText));

//e-mail的字符串内容

<a href="mailto:my@email.com">my@email.com</a>

去掉下划线的方法

email.setText(c.getString(5));
website.setText(c.getString(6));
Linkify.addLinks(email, Linkify.ALL);
Linkify.addLinks(website, Linkify.ALL);

private void stripUnderlines(TextView textView) {
Spannable s = (Spannable)textView.getText();
URLSpan[] spans = s.getSpans(0, s.length(), URLSpan.class);
for (URLSpan span: spans) {
int start = s.getSpanStart(span);
int end = s.getSpanEnd(span);
s.removeSpan(span);
span = new URLSpanNoUnderline(span.getURL());
s.setSpan(span, start, end, 0);
}
textView.setText(s);
}

需要重定义urlspan

 private class URLSpanNoUnderline extends URLSpan {
public URLSpanNoUnderline(String url) {
super(url);
}
@Override public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(false);
}
}
