Auto-link for TextView

In Android, auto-link for text doesn’t mean only for URL web addresses, but also for phone numbers, map addresses or emails.

Something like this:

Linkify (color default)

The class Linkify is used to support every TextView or Spannable in auto-link these texts.

The sample code demonstrate the above image:

package pete.android.study;

import android.app.Activity;
import android.content.res.ColorStateList;
import android.graphics.Color;
import android.os.Bundle;
import android.text.util.Linkify;
import android.widget.TextView;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TextView tvDisplay = (TextView)findViewById(R.id.tvDisplay);
        String data = "" +
        "This is a sample of using Linkify to create auto-link to your text entry.\n" +
        "\n" +
        "URL: http://xjaphx.wordpress.com/ \n" +
        "Email: pete.houston.17187@gmail.com \n" +
        "Phone: (82)-10-9887-6231 \n" +
        "Address: 436 Mayfield Ave, Stanford, CA \n" +
        "\n" +
        "It's nice, isn't it?";

        if(tvDisplay != null) {
	        tvDisplay.setText(data);
	        Linkify.addLinks(tvDisplay, Linkify.ALL);
        }
    }
}

You can specify what kind of auto-link you want to create by these options: Linkify.EMAIL_ADDRESSES for email, Linkify.MAP_ADDRESSES for map address, Linkify.PHONE_NUMBERS for phone numbers, or all links by Linkify.ALL.

If you don’t want the default blue linking color, you can change its color through the TextView by using: setTextLinkColor().

Linkify (Yellow color)

tvDisplay.setLinkTextColor(Color.YELLOW);

That’s all! Hope you learn something from this.

Cheers,
