Add HTML to Android Activity or TextView

This is an example to demonstrate how we can add HTML in Android TextView using Java code,

1. Add TextView to your Activity:

   <androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:app="http://schemas.android.com/apk/res-auto"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       tools:context=".MainActivity">
   
   <TextView
         android:id = "@+id/htmlView"
         android:layout_width = "wrap_content"
         android:layout_height = "wrap_content" />
   
   </androidx.coordinatorlayout.widget.CoordinatorLayout>

2. Now lets check the Java Code: src/MainActivity.java

   public class MainActivity extends AppCompatActivity {
      String htmlCodeText = "<p style="background:green">Hello, this a HTML code!</p>";
      
      @Override
      protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         TextView htmlToTextView = findViewById(R.id.htmlView);
         htmlToTextView.setText(HtmlCompat.fromHtml(htmlCodeText, 0));
      }
   }
