How to create multiple styles inside a TextView in Android?


This example demonstrates how do I create multiple styles inside a TextView in android.

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:layout_above="@id/textView2"
      android:layout_marginBottom="16dp"
      android:id="@+id/textView1"
      android:textSize="16dp"
      android:padding="4dp"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerInParent="true"/>
   <TextView
      android:id="@+id/textView2"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textSize="16dp"
      android:padding="4dp"
      android:layout_centerInParent="true"/>
   <TextView
      android:layout_below="@id/textView2"
      android:layout_marginTop="16dp"
      android:id="@+id/textView3"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textSize="16dp"
      android:padding="4dp"/>
</RelativeLayout>

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

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Html;
import android.text.Spanned;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   TextView textView1, textView2, textView3;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textView1 = findViewById(R.id.textView1);
      textView2 = findViewById(R.id.textView2);
      textView1.setText(Html.fromHtml("Multiple style inside android textView: bold text: "
         + "<b>bold text</b>, italic text: <i>italic text</i>, small font: <small>small "
         + "text</small>, "
         + "font color: <font color=\"blue\">Text Color</font>, "
         + "font color with bold text: <fontcolor=\"green\"><b>Bold with font "
         + "color</b></font>"));
      Spanned text = Html.fromHtml("Multiple style inside android textView: bold text: "
         + "<b>bold text</b>, "
         + "italic text: <i>italic text</i>, small font: <small>small text</small>, font "
         + "color: <font color=\"blue\">Text Color</font>, "
         + "font color with bold text: <fontcolor=\"green\"><b>Bold with font "
         + "color</b></font>");
      textView2.setText(text);
      textView3 = findViewById(R.id.textView3);
      textView3.setText(Html.fromHtml(getString(R.string.textStyle)));
   }
}

Step 4 − Open res/values/strings.xml and add the following code −

<resources>
<string name="app_name">Sample</string>
   <string name="textStyle">
      <![CDATA[
         Multiple style inside android textView: bold text: <b>bold
         text</b>, italicText text: <i>italic text</i>, small font:
         <small>small text</small>,
         font color: <font color="blue"<Text Color</font<, font
         color with bold text: <font color="green"><b>Bold with font
         color</b></font>
      ]]>
   </string>
</resources>

Step 5 − 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 −
