Add this line to your build.gradle file under your module directory.

compile 'com.github.mr5:icarus:0.1.14'

Java codes:

import android.app.Activity;
import android.webkit.WebView;
import android.widget.TextView;

import com.github.mr5.icarus.entity.Options;
import com.github.mr5.icarus.button.TextViewButton;
class EditorActivity extends Activity {
 protected WebView webView;
    protected Icarus icarus;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Get WebView from your layout, or create it manually.
        setContentView(R.layout.activity_main);
        webView = (WebView) findViewById(R.id.editor);
        // I offered a toolbar to manage editor buttons which implements TextView that with icon fonts. 
        // It's just a collection, not an Android View implementation. 
        // TextViewToolbar will listen click events on all buttons that added to it. 
        // You can implement your own `Toolbar`, to prevent these default behaviors.
        TextViewToolbar toolbar = new TextViewToolbar();
        Options options = new Options();
        options.setPlaceholder("Placeholder...");
        icarus = new Icarus(toolbar, options, webView);
        TextView boldButton = new TextViewButton()
        boldButton.setName(Button.NAME_BOLD);
  toolbar.addButton(boldButton);
        icarus.render();
    }
 }

Sample

Button Names

see Button.java

Options

placeholder: String

Placeholder of Editor. Use the placeholder attribute value of the textarea by default.

default: "Icarus editor."

Example:

options.setPlaceholder("Input something...");

defaultImage: String

Default image placeholder. Used when inserting pictures in Edtior.

default: "images/image.png"

Example:

options.setDefaultImage("file:///android_asset/xxx.jpg");

cleanPaste: Boolean

Remove all styles in paste content automatically.

default: false

Example:

options.setCleanPaste(true);

allowedTags: String[]

Tags that are allowed in Editor

default: {"br", "span", "a", "img", "b", "strong", "i", "strike", "u", "font", "p", "ul", "ol", "li", "blockquote", "pre", "code", "h1", "h2", "h3", "h4", "hr"}

Example:

// option replacement.
options.setAllowedTags(Arrays.asList("a", "span", "img");
// add tag to current tag list.
options.addAllowedTag("pre");

allowedAttributes: Map<String, List<String>>

Whitelist of tag attributes. Note that custom whitelist will be merged into the default one.

default:

img: {"src", "alt", "width", "height", "data-non-image"}
a: {"href", "target"}
font: {"color"}
code: {"class"}

Example:

// option replacement.
options.setAllowedAttributes(new HashMap<String, List<String>>());
// add new attribute to current tag list.
options.addAllowedAttributes("a", Arrays.asList("class", "src", "alt", "data-type"));

Load Javascript or Stylesheet files.

icarus.loadCSS("file:///android_asset/editor.css");
icarus.loadJs("file:///android_asset/test.js");

Popover

Some buttons depend user's actions, such as Button.NAME_LINK, Button.NAME_IMAGE. So you want to show a popover for user to do these actions. Icarus offered 3 Popover Implementations, HtmlPopoverImpl, ImagePopoverImpl, LinkPopoverImpl,

Samples:

TextView imageButtonTextView = (TextView) findViewById(R.id.button_image);
imageButtonTextView.setTypeface(iconfont);
TextViewButton imageButton = new TextViewButton(imageButtonTextView, icarus);
imageButton.setName(Button.NAME_IMAGE);
imageButton.setPopover(new ImagePopoverImpl(imageButtonTextView, icarus));

toolbar.addButton(imageButton);

You can implement your own popover to handler user's actions.

Insert html to current selection

icarus.insertHtml("<iframe src=\\"xxx\\"></iframe>");

Contents getting and setting

// Get contents
icarus.getContent(new Callback() {
                @Override
                public void run(String params) {
                 Gson gson = new Gson();
           Html html = gson.fromJson(params, Html.class);
     Log.d("Content gotten", html.getContent());
                }
            });


// Set contents
icarus.setContent("new content");
