剪辑 GradientDrawable.setCornerRadii 不工作

Question

我正在尝试创建具有自定义半径的视图，但在使用 GradientDrawable.setCornerRadii...
Line 时遇到问题如果我使用下面的代码，视图会剪辑其中的所有子视图

public void SetCornerRadius(View v,int Radius){
        GradientDrawable shape = new GradientDrawable();
        shape.setShape(GradientDrawable.RECTANGLE);
        shape.setCornerRadius((int)Px2Dp(Radius));
        v.setBackground(shape);
        v.setOutlineProvider(ViewOutlineProvider.BACKGROUND);
        v.setClipToOutline(true);
    }

但是如果我对不同的角半径使用下面的代码，那么当子视图超出父视图时，剪裁无法按预期工作

public void SetDifferentCornerRadius(View v,int TopLeftRadius,int TopRightRadius,int BottomLeftRadius,int BottomRightRadius,String backgroundColor){
        GradientDrawable shape = new GradientDrawable();
        ViewGroup vg = (ViewGroup)v;
        shape.setShape(GradientDrawable.RECTANGLE);
        shape.setColor(Color.parseColor(backgroundColor));
        shape.setCornerRadii(new float[] { (int)Px2Dp(TopLeftRadius),(int)Px2Dp(TopLeftRadius),(int)Px2Dp(TopRightRadius),(int)Px2Dp(TopRightRadius),(int)Px2Dp(BottomRightRadius),(int)Px2Dp(BottomRightRadius),(int)Px2Dp(BottomLeftRadius),(int)Px2Dp(BottomLeftRadius)});
        v.setBackground(shape);
        v.setOutlineProvider(ViewOutlineProvider.BACKGROUND);
        v.setClipToOutline(true);

    }

Answer 1

我猜它不起作用，因为 setClipToOutline 仅适用于以下形状。

Currently, only Outlines that can be represented as a rectangle, circle, or round rect support clipping.
