If a user applies a style, it will be applicable to the whole content of the block.

If a user is typing a paragraph and presses enter, we need to add another row(edittext).

Initially, there will be an editext with the cursor on it.

So there are some basic rules which need to be followed. In order to make a stable editor, we need to make its reactions genuine. This is the simplest part, it will be a simple view which will draw a line.įor Group 3: We can have a view with line drawable. The actions we can perform on the Group 3 . Also, it needs to store the text entered into the EditText .įor Group 2: We can have a Custom View with ImageView and Edittext. It will be responsible for uploading an image to the server and storing back the URL itself. This can be a Custom view composed of an ImageView and an Edittext(for the caption on image).

Image captions can be taken via Edittext.

The actions we can perform on the Group 2. This block (view) will be added or removed from the editor. We will read all of them while we collect editor data (covered later) and store on the device or send it to the server.įor Group 1: We can have a custom view with all the parameter. This view will store all the configurations applied.

Show blockquote by changing the background view of edittext.

The actions we can perform on the Group 1 . In other words, Text, Image (multimedia), and Horizontal divider. Here, we've grouped the elements based on the properties required to render them. Group 1: Heading styles, Bold, Italics, Blockquotes, Lists We can sort the list and categorize them into groups like. Skeleton of our editorI think the internal skeleton is clear. The parent view keeps track of indexes of each view added to the stack and also the view in focus. Until user presses enter, the content goes to the same edittext.Īfter enter is pressed a new edittext is inserted into the stack. Initially, there is an edittext added to the stack and focussed. In Android, it simply can be an extended version of LinearLayout in vertical orientation . There is a Parent View which adds view in vertical order. Now let's explore more on this, Basics of the internal architecture

Each element is independently stylable entity, may it be Bold, H2 or Blockquote, Image or List Item etc. Think editor as a container and elements are added/removed to/from it based on user actions (enter or backpressed). If we go on pressing enter, new boxes are added. Hence we can conclude that it is not a single editext and Spans are not used. On Typing somethingWhen we press enter, cursor moves to the new line and another box is created. Now let's see another screenshot when we type something The given picture is medium app opened in developer mode turned on. Internal Architecture of the Editor X-ray of the editor So to verify, let's get into depth and try to observe the 'bars behind the concrete'. This involves a lot of operation in a finite time, hence it will affect the UI rendering performance and will produce a terrible experience while the user tries to type too fast or delete any content too fast.

On each character change in the edittext, it will have to update spans. This is the interface for text to which markup objects can be attached and detached.Īttach the specified markup object to the range start.end of the text.Īt the core, spannable perform string search operation from its start to end index and then apply the type of Spans. But, Using spannable it would be difficult to manage the format of long text like 10k words. The user can type their content and format it accordingly.Īt once it seems to be a Custom EditText which uses Spannables to format its content. All the editing tools are presented on the bottom toolbar. The above is the screenshot of the editor, it is a clean and intuitive interface. A WYSIWYG editor is a system in which content can be edited in a form closely resembling its appearance when printed or displayed as a finished document. WYSIWYG is an acronym for "what you see is what you get". I've also given a link to my sample at the end of this blog for your reference in case you get stuck somewhere or you directly want to go through the code.
