Android Linkify text - Spannable Text in Single Text View - As like Twitter tweet
I have used the same thing which I answered here in This Question
For that I have used this LinkEnabledTextView and that become easy for me to do the task.
Android Linkify both web and @mentions all in the same TextView
Here's my code to linkify all Twitter links (mentions, hashtags and URLs):
TextView tweet = (TextView) findViewById(R.id.tweet);
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(tweet, mentionPattern, mentionScheme, null, filter);
Pattern hashtagPattern = Pattern.compile("#([A-Za-z0-9_-]+)");
String hashtagScheme = "http://www.twitter.com/search/";
Linkify.addLinks(tweet, hashtagPattern, hashtagScheme, null, filter);
Pattern urlPattern = Patterns.WEB_URL;
Linkify.addLinks(tweet, urlPattern, null, null, filter);
How to make ListItem Textview to work as Twitter Tweets and get Different Linkify clicks?
For twitter app, I had also the same requirement to click on handles of tweets and also click on the text of tweet to get Tweet detail.
For that I have used this LinkEnabledTextView and that become easy for me to do the task.
I just added the class in my project and then in List Item instead simple TextView I used object/instance of the LinkEnabledTextView.
There is a complete demo in above link, Please check that.
EDIT: Adapter Code Specially check onTextLinkClick() and then holder.twtdata.setOnClickListener()
private static class EfficientAdapter extends BaseAdapter implements TextLinkClickListener {

text colors for one TextView using two Linkify's and weblinks clickable
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);
}
}

Android: multiple textview like a single text
you can use FlowLayout if you really need this. But if you can, you should use one textView and format text using spannables.
How to implement a OnClick for a text/link which is in a TextView
You should use built-in linkify. Read this tutorial, easy to understand:

final String emailAddress = "info@123456.com";
TextView text = (TextView)findViewById(R.id.textview);
Spannable span = Spannable.Factory.getInstance().newSpannable("For more details on the app visit us at " + webAddress + " or write to us at " + emailAddress);
ClickableSpan webClickSpan = new ClickableSpan() {
@Override
public void onClick(View v) {
Uri uriUrl = Uri.parse("http://" + webAddress);
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
startActivity(launchBrowser);
} };
ClickableSpan emailClickSpan = new ClickableSpan() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{emailAddress});
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "email body.");
startActivity(Intent.createChooser(intent, "Send Email"));
} };
span.setSpan(webClickSpan, 40, 40 + webAddress.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(emailClickSpan, 73, span.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
text.setText(span);
text.setMovementMethod(LinkMovementMethod.getInstance());
