4.) Build and run your code and check the output given below in the doc.

Steps:

1.) Create a project named TextViewLinkDemo and set the information as stated in the image.

Build Target: Android 2.3
Application Name: TextViewLinkDemo
Package Name: com.org. TextViewLinkDemo
Activity Name: TextViewLinkDemo
Min SDK Version: 9

2.) Open TextViewLinkDemo.java file and write following code there:

package com.org.TextViewLinkDemo;

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;

        SpannableString ss = new SpannableString(
            "text4: Click here to dial the phone.");

        ss.setSpan(new StyleSpan(Typeface.BOLD), 0, 6,

        TextView t4 = (TextView) findViewById(R.id.text4);
        t4.setText(ss);
        t4.setMovementMethod(LinkMovementMethod.getInstance());
