ShapeOfView

Give a custom shape to any android view Useful for Material Design 2

Breaking change

the old package com.github.florent37 has been replaced by io.github.florent37

Download

//using maven central

dependencies {
    implementation 'io.github.florent37:shapeofview:1.4.7'
}

Sample

What you can do with Shape Of View :

Use implemented shapes

ShapeOfView disable the background property of your view, please specify a child with a background to enable it

<io.github.florent37.shapeofview.shapes.CircleView
   <FrameLayout
      android:background="@color/blue"

ShapeOfView came with pre-created shapes :

Circle

<io.github.florent37.shapeofview.shapes.CircleView
        android:layout_width="150dp"
        android:layout_height="150dp"

        android:elevation="4dp"
        app:shape_circle_borderColor="@android:color/black"
        app:shape_circle_borderWidth="2dp">

            <!-- YOUR CONTENT -->

             app:shape_dottedEdgesCutCorner_bottomRightSize="8dp"
             >

             <!-- YOUR CONTENT -->

 </io.github.florent37.shapeofview.shapes.DottedEdgesCutCornerView>

Animation

All shapes methods can be animated

For example, you can animate a RoundRect corner :

ValueAnimator.ofFloat(0f, 200f, 0f).apply {
     addUpdateListener { animation -> roundRect.bottomLeftRadius = (animation.animatedValue as Float).toInt() }
     duration = 800
     repeatCount = ValueAnimator.INFINITE
     repeatMode = ValueAnimator.REVERSE
}.start()

Create you own shape

You can use custom shape to cut your view

Using Drawable (no elevation)

<io.github.florent37.shapeofview.ShapeOfView
        android:layout_width="100dp"
        android:layout_height="100dp"

        app:shape_clip_drawable="@drawable/YOUR_DRAWABLE"
        >

    <!-- YOUR CONTENT -->

 </io.github.florent37.shapeofview.ShapeOfView>

Using Path (with elevation)

This method generates also a shadow path (with Lollipop elevation API 21+)

Wrap your view with a ShapeOfView

<io.github.florent37.shapeofview.ShapeOfView
        android:id="@+id/myShape"
        android:layout_width="30dp"
        android:layout_height="15dp"
        android:elevation="6dp">

        <!-- YOUR CONTENT -->

 </io.github.florent37.shapeofview.ShapeOfView>

Then generate a path in your code :

ShapeOfView shapeOfView = findViewById(R.id.myShape)
shapeOfView.setClipPathCreator(new ClipPathManager.ClipPathCreator() {
       @Override
       public Path createClipPath(int width, int height) {
           final Path path = new Path();

            //eg: triangle
           path.moveTo(0, 0);
           path.lineTo(0.5 * width, height);
           path.lineTo(width, 0);
           path.close();

           return path;
       }
});

In some case you have to specify requiresBitmap = true to enable ShapeOfView to draw the shape inside a bitmap before clipping your view. It will be less efficient but can make your custom shape work.

Contribute

Feel free to fork this project, and add customs shapes

Then make a merge-request after updated the README with a sample of your shape, including a preview

HISTORY

1.4.5 Removed DiagonalView's Direction : if diagonalAngle > 0 ? DIRECTION_LEFT : DIRECTION_RIGHT

1.4.5 Removed ArcView's ArcDirection : CROP_OUTSIDE if arcHeight > 0, CROP_INSIDE if arcHeight < 0

1.4.1 Added Dotted Edge, thanks to @khunzohn

1.4.0 Support AndroidX

1.3.2 Backport of 1.3.0 for api 14+
