android - How to make ListItem Textview to work as Twitter Tweets and get Different Linkify clicks?

Question

For Eg :

Follow @SoccerBible, RT this & if Ronaldo scores https://bit.ly/133/com tonight we'll give away a pair of Nike Clash Vapor 8's to one lucky winner! #RonaldoComp

In my listview component. Where i am showing list of tweets. I have colored the @,# and urls in the tweet text. The all are dynamically clickable.

My question is how can i make the non-colored text as clickable. I have used Linkify.addLinks and Pattern API to make them clickable. But i wanted the non @,# and url text to be clicakble without adding any color to it.

Thanks, dominic

Answer 1

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 {
        private LayoutInflater mInflater;
        static int pos =0;
        public EfficientAdapter(Context context) {
            mInflater = LayoutInflater.from(context);
        }

        public int getCount() {
            return timelines.length;
        }

        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }

        public View getView(final int position, View convertView,
                ViewGroup parent) {

            ViewHolder holder;
            if (convertView == null) {
                convertView = mInflater.inflate(R.layout.listtimerow, null);
                holder = new ViewHolder();
                holder.twtdata = (LinkEnabledTextView) convertView
                        .findViewById(R.id.twtdata);
                holder.twtnm = (TextView) convertView
                        .findViewById(R.id.twthandle);
                holder.twtimg = (ImageView) convertView
                        .findViewById(R.id.avatar);
                holder.twtdt = (TextView) convertView
                        .findViewById(R.id.created);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }
               holder.twtdata.setOnTextLinkClickListener(this);
                holder.twtdata.gatherLinksForText(timelines[position]);
                holder.twtdata.setTextColor(Color.BLACK);
                holder.twtdata.setLinkTextColor(Color.BLUE);

                MovementMethod m = holder.twtdata.getMovementMethod();
                if ((m == null) || !(m instanceof LinkMovementMethod)) {
                    if (holder.twtdata.getLinksClickable()) {
                        holder.twtdata.setMovementMethod(LinkMovementMethod.getInstance());
                    }
                }

            if (bmpimg1[position] != null)
                holder.twtimg.setImageBitmap(bmpimg1[position]);
            holder.twtnm.setText(twitterhandles[position]);
            Date credate = new Date(created[position]);

            String dt = credate.getDate() + " "
                    + getMonthName(credate.getMonth());
            holder.twtdt.setText(dt);

            holder.twtdata.setOnClickListener(new OnClickListener() {
