Well, actually you can embed a callback link to a TextView.
You just need special clickable span, which will call your methods
when clicked.
Here's an excerpt from my HTMLDialog class:
public void setHTML(String html) {
html=html.replaceAll("(\r\n|\n)","");
Spanned spannedHTML=Html.fromHtml(html);
SpannableString message=new SpannableString(spannedHTML.toString());
Object[] spans=spannedHTML.getSpans(0,spannedHTML.length
(),Object.class);
for (Object span: spans) {
int start=spannedHTML.getSpanStart(span);
int end=spannedHTML.getSpanEnd(span);
int flags=spannedHTML.getSpanFlags(span);
if (span instanceof URLSpan) {
URLSpan urlSpan=(URLSpan)span;
if (urlSpan.getURL().startsWith(CallbackSpan.PREFIX)) {
span=new CallbackSpan(urlSpan.getURL());
}
}
message.setSpan(span,start,end,flags);
}
m_message.setText(message);
}
....
protected void onCallback(String data) {
....
}
private final class CallbackSpan extends ClickableSpan {
public CallbackSpan(String url) {
int start=(url.startsWith(PREFIX)?PREFIX.length():0);
m_data=url.substring(start);
}
public void onClick(View view) {
onCallback(m_data);
}
public static final String PREFIX="callback:";
private String m_data;
}
and then you can put links of form <a href='callback:mydata'>callback
link</a> anywhere in your document.
Don't forget to setup your TextView:
m_message.setLinksClickable(true);
m_message.setMovementMethod(LinkMovementMethod.getInstance());
