I want twitter mentions to be in redcolor and hashtags is another color,if any tweet contains any weblinks.. links should be clickable and passed through intent to another Activity(WebView
).
How can I achieve this ??
TransformFilter filter = new TransformFilter() {
public final String transformUrl(final Matcher match, String url) {
return match.group();
}
};
Pattern mentionPattern = Pattern.compile("@([A-Za-z0-9_-]+)");
String mentionScheme = "http://www.twitter.com/";
Linkify.addLinks(tvMessage, mentionPattern, mentionScheme, null, filter);
Pattern hashtagPattern = Pattern.compile("#([A-Za-z0-9_-]+)");
String hashtagScheme = "http://www.twitter.com/search/";
Linkify.addLinks(tvMessage, hashtagPattern, hashtagScheme, null, filter);
Pattern urlPattern = Patterns.WEB_URL;
Linkify.addLinks(tvMessage, urlPattern, null, null, filter);
// tvMessage.setLinkTextColor(Color.parseColor("#3467BB"));

Finally i have achieved hashtags weblinks clickable and made them very attractive by keeping different colors
using android sdk SpannableString and it's ClickableSpan .
private void Linkfiy(String a, TextView textView) {
Pattern urlPattern = Patterns.WEB_URL;
Pattern mentionPattern = Pattern.compile("(@[A-Za-z0-9_-]+)");
Pattern hashtagPattern = Pattern.compile("#(\\w+|\\W+)");
Matcher o = hashtagPattern.matcher(a);
Matcher mention = mentionPattern.matcher(a);
Matcher weblink = urlPattern.matcher(a);
SpannableString spannableString = new SpannableString(a);
//#hashtags
while (o.find()) {
spannableString.setSpan(new NonUnderlinedClickableSpan(o.group(),
0), o.start(), o.end(),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
// --- @mention
while (mention.find()) {
spannableString.setSpan(
new NonUnderlinedClickableSpan(mention.group(), 1), mention.start(), mention.end(),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
//@weblink
while (weblink.find()) {
spannableString.setSpan(
new NonUnderlinedClickableSpan(weblink.group(), 2), weblink.start(), weblink.end(),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
textView.setText(spannableString);
textView.setMovementMethod(LinkMovementMethod.getInstance());
}
NonUnderlinedClickableSpan class
public class NonUnderlinedClickableSpan extends ClickableSpan {
int type;// 0-hashtag , 1- mention, 2- url link
String text;// Keyword or url
String time;
public NonUnderlinedClickableSpan(String text, int type) {
this.text = text;
this.type = type;
this.time = time;
}
@Override
public void updateDrawState(TextPaint ds) {
//adding colors
if (type == 1)
ds.setColor(InstagramIndetail.this.getResources().getColor(
R.color.link_color_mention));
else if (type == 2)
ds.setColor(InstagramIndetail.this.getResources().getColor(
R.color.link_color_url));
else
ds.setColor(InstagramIndetail.this.getResources().getColor(
R.color.link_color_hashtag));
ds.setUnderlineText(false);
// ds.setTypeface(Typeface.DEFAULT_BOLD);
}
@Override
public void onClick(View v) {
Debug.e("click done", "ok " + text);
if (type == 0) {
//pass hashtags to activity using intents
} else if (type == 1) {
//do for mentions
} else {
// passing weblinks urls to webview activity
startWebViewActivity(text);
}
}
}
