How to set the part of the Android TextView as clickable?


This example demonstrates how do I set the part of the Android textView as clickable.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <TextView
      android:id="@+id/textView"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="I want THIS and THIS to be CLICKED!"
      android:layout_centerInParent="true"
      android:textSize="16sp"
      android:textStyle="bold|italic"/>
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   TextView textView;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textView = findViewById(R.id.textView);
      String text = "I want THIS and THIS to be CLICKED";
      SpannableString spannableString = new SpannableString(text);
      ClickableSpan clickableSpan1 = new ClickableSpan() {
         @Override
         public void onClick(View widget) {
            Toast.makeText(MainActivity.this, "THIS", Toast.LENGTH_SHORT).show();
         }
      };
      ClickableSpan clickableSpan2 = new ClickableSpan() {
         @Override
         public void onClick(View widget) {
            Toast.makeText(MainActivity.this, "THIS", Toast.LENGTH_SHORT).show();
         }
      };
      ClickableSpan clickableSpan3 = new ClickableSpan() {
         @Override
         public void onClick(View widget) {
            Toast.makeText(MainActivity.this, "CLICKED", Toast.LENGTH_SHORT).show();
         }
      };
      spannableString.setSpan(clickableSpan1, 7,11, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
      spannableString.setSpan(clickableSpan2, 16,20, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
      spannableString.setSpan(clickableSpan3, 27,34, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
      textView.setText(spannableString);
      textView.setMovementMethod(LinkMovementMethod.getInstance());
   }
}

Step 4 - Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  Icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
