这就是我的自定义可绘制对象默认的外观。
但是当滚动时,它会与 AppBarLayout 重叠。
Drawable 的代码如下所示:
@Override
public void draw(@NonNull Canvas canvas) {
// get drawable dimensions
Rect bounds = getBounds();
float width = bounds.right - bounds.left;
float height = bounds.bottom - bounds.top;
float w2 = width / 2;
float h2 = height / 2;
float radius = Math.min(w2, h2) - mStrokeWidth / 2;
mPath.reset();
mPath.addCircle(width / 2, height / 2, radius, Path.Direction.CW);
canvas.clipPath(mPath);
// draw background gradient
float barHeight = height / themeColors.length;
mRectF.left = 0;
mRectF.top = 0;
mRectF.right = width;
mRectF.bottom = height;
for (int i = 0; i < themeColors.length; i++) {
mPaint.setColor(themeColors[i]);
canvas.drawRect(0, i * barHeight, width, (i + 1) * barHeight, mPaint);
}
mRectF.set(0, 0, width, height);
canvas.clipRect(mRectF, Region.Op.REPLACE);
if (mStrokeWidth != 0)
canvas.drawCircle(width / 2, height / 2, width / 2 - mStrokeWidth / 2, mStrokePaint);
}
支持库版本:25.3.1、26.1.0
我试过的: - 剪切路径而不是替换的不同区域值 - 先剪切路径矩形,然后剪切圆形。
我该如何解决 ?
