Getting Started

To start with this , you need to just simply add the dependencies in gradle file of app module like this

or your can also import the :photoeditor module from sample for customization

Setting up the View

First you need to add PhotoEditorView in your xml layout

 <
        android:id="@+id/photoEditorView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:photo_src="@drawable/got_s" />
  

Your can define your drawable or color resource directly using app:photo_src

Your can set the image programmatically by getting source from PhotoEditorView which will return a ImageView so that you can load image from resources,file or (Picasso/Glide)

PhotoEditorView mPhotoEditorView = findViewById(R.id.photoEditorView);

mPhotoEditorView.getSource().setImageResource(R.drawable.got);

Building a PhotoEditor

To use the image editing feature you need to build a PhotoEditor which requires a Context and PhotoEditorView which we have setup in our xml layout

//Use custom font using latest support library
Typeface mTextRobotoTf = ResourcesCompat.getFont(this, R.font.roboto_medium);

//loading font from assest
Typeface mEmojiTypeFace = Typeface.createFromAsset(getAssets(), "emojione-android.ttf");

mPhotoEditor = new PhotoEditor.Builder(this, mPhotoEditorView)
         .setPinchTextScalable(true)
         .setDefaultTextTypeface(mTextRobotoTf)
         .setDefaultEmojiTypeface(mEmojiTypeFace)
         .build();

You can customize the properties in the PhotoEditor as per your requirement

Property	Usage
setPinchTextScalable()	set false to disable pinch to zoom on text insertion.By default its true
setDefaultTextTypeface()	set default text font to be added on image
setDefaultEmojiTypeface()	set default font specifc to add emojis

That's it we are done with setting up our library

Drawing

We can customize our brush and paint with different set of property.To start drawing on image we need to enable the drawing mode

Type	Method
Enable/Disable	mPhotoEditor.setBrushDrawingMode(true);
Bursh Size (px)	mPhotoEditor.setBrushSize(brushSize)
Color Opacity (In %)	mPhotoEditor.setOpacity(opacity)
Brush Color	mPhotoEditor.setBrushColor(colorCode)
Brush Eraser	mPhotoEditor.brushEraser()

Note: Whenever you set any property for brush for drawing it will automatically enables the drawing mode

Filter Effect

You can apply inbuild filter to the source images using

mPhotoEditor.setFilterEffect(PhotoFilter.BRIGHTNESS);

!

You can also apply custom effect using Custom.Builder

mPhotoEditor.addText(inputText, colorCode);

It will take default fonts provided in the builder,If you want different fonts for different text you can set typeface with each text like this

mPhotoEditor.addText(mTypeface,inputText, colorCode);

In order to edit the text you need the view which you will receive in you PhotoEditor callback.This callback will trigger when you Long Press the added text

mPhotoEditor.setOnPhotoEditorListener(new OnPhotoEditorListener() {
           @Override
           public void onEditTextChangeListener(View rootView, String text, int colorCode) {
               
           }
       });

Now you can edit the text with a view like this

mPhotoEditor.editText(rootView, inputText, colorCode);

Emoji

You can add the Emoji by PhotoEditor.getEmojis(getActivity()); which will return a list of emojis unicode.

mPhotoEditor.addEmoji(emojiUnicode);

It will take default fonts provided in the builder,If you want different Emoji fonts for different emoji you can set typeface with each Emoji like this

mPhotoEditor.addEmoji(mEmojiTypeface,emojiUnicode);

Adding Images/Stickers

You need to provide a Bitmap to add you Images mPhotoEditor.addImage(bitmap);

Undo and Redo

  mPhotoEditor.undo();
  mPhotoEditor.redo();

Deleting

For deleting a Text/Emoji/Image you can click on the view to toggle the view highlighter box which will have a close icon so by on clicking on the icon you can delete the view

Saving

You need provide a file with callback method when edited image is saved

 mPhotoEditor.saveAsFile(filePath, new PhotoEditor.OnSaveListener() {
                 @Override
                 public void onSuccess(@NonNull String imagePath) {
                    Log.e("PhotoEditor","Image Saved Successfully");
                 }

                 @Override
                 public void onFailure(@NonNull Exception exception) {
                     Log.e("PhotoEditor","Failed to save Image");
                 }
             });
