DrawingView

A simple view to draw on supporting:

• undo, redo, eraser, clear
• set brush color and size
• set callback listeners for drawing and canvas state changes

Simply create view in your code or in xml and you're good to go.

Nice! How do I get started?

Make sure root build.gradle repositories include JitPack

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

And DrawingView dependency is added to app build.gradle

dependencies {
    implementation 'com.github.mvojtkovszky:DrawingView:$latest_version'
}

Keep strokes inside the view

By default, DrawingView preserves its original behavior and accepts coordinates from a gesture that moves outside its bounds. Enable clamping when adjacent UI must never contain drawing data:

<com.vojtkovszky.drawingview.DrawingView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:clampDrawingToBounds="true" />

Or configure it programmatically:

drawingView.clampDrawingToBounds = true
