Sure. Here are the steps on how to add Summernote editor in Android Studio project:

1. Add the Summernote editor dependency to your project. You can do this by adding the following line to your project's build.gradle file:

Code snippet

dependencies {
    implementation 'com.github.summernote:summernote-android:0.8.18'
}

1. Add the Summernote editor layout to your project's layout file. You can do this by adding the following code to your project's activity_main.xml file:

Code snippet

<com.summernote.summernote:summernote
    android:id="@+id/summernote"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

1. Initialize the Summernote editor in your project's MainActivity.java file. You can do this by adding the following code to your project's MainActivity.java file:

Code snippet

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize the Summernote editor
        Summernote summernote = findViewById(R.id.summernote);
        summernote.setPlaceholder("Enter your text here...");
    }
}

1. Run the app and test the Summernote editor.

This code will initialize the Summernote editor and set the placeholder text to "Enter your text here...". When you run the app, you will see a Summernote editor in the layout. You can use the Summernote editor to edit text.

You can customize the Summernote editor by setting the following properties:

• Placeholder: The placeholder text that will be displayed in the Summernote editor.
• Theme: The theme of the Summernote editor.
• Plugins: The plugins that will be enabled in the Summernote editor.
• Language: The language of the Summernote editor.

You can also add other features to the Summernote editor, such as a list of items, a text field, or a progress bar.
