Examples with RadialGradient android.graphics.RadialGradient used on opensource projects

Example 1 with RadialGradient

use of android.graphics.RadialGradient in project Depth-LIB-Android- by danielzeller.

the class CustomShadow method buildShadowCorners.

private void buildShadowCorners() {
    RectF innerBounds = new RectF(-mCornerRadius, -mCornerRadius, mCornerRadius, mCornerRadius);
    RectF outerBounds = new RectF(innerBounds);
    outerBounds.inset(-mShadowSize, -mShadowSize);
    if (mCornerShadowPath == null) {
        mCornerShadowPath = new Path();
    } else {
        mCornerShadowPath.reset();
    }
    mCornerShadowPath.setFillType(Path.FillType.EVEN_ODD);
    mCornerShadowPath.moveTo(-mCornerRadius, 0);
    mCornerShadowPath.rLineTo(-mShadowSize, 0);
    // outer arc
    mCornerShadowPath.arcTo(outerBounds, 180f, 90f, false);
    // inner arc
    mCornerShadowPath.arcTo(innerBounds, 270f, -90f, false);
    mCornerShadowPath.close();
    float startRatio = mCornerRadius / (mCornerRadius + mShadowSize);
    mCornerShadowPaint.setShader(new RadialGradient(0, 0, mCornerRadius + mShadowSize, new int[] { mShadowStartColor, mShadowStartColor, mShadowEndColor }, new float[] { 0f, startRatio, 1f }, Shader.TileMode.CLAMP));
    // we offset the content shadowSize/2 pixels up to make it more realistic.
    // this is why edge shadow shader has some extra space
    // When drawing bottom edge shadow, we use that extra space.
    mEdgeShadowPaint.setShader(new LinearGradient(0, -mCornerRadius + mShadowSize, 0, -mCornerRadius - mShadowSize, new int[] { mShadowStartColor, mShadowStartColor, mShadowEndColor }, new float[] { 0f, .5f, 1f }, Shader.TileMode.CLAMP));
    mEdgeShadowPaint.setAntiAlias(false);
