如何在另一个shapeDrawable中以编程方式绘制一个较小的ShapeDrawable [英] How to draw a smaller ShapeDrawable inside another shapeDrawable programmatically

问题描述

我试图在另一个圆圈内画一个较小的圆。
看起来很简单，但是我遇到麻烦，找不到答案。
我使用的代码是：

Im trying to draw a smaller circle within another circle. It seems pretty simple but Im having trouble with this and couldnt find an answer. The code im using is:

    ShapeDrawable biggerCircle= new ShapeDrawable( new OvalShape());
    biggerCircle.setIntrinsicHeight( 60 );
    biggerCircle.setIntrinsicWidth( 60);
    biggerCircle.setBounds(new Rect(0, 0, 60, 60));
    biggerCircle.getPaint().setColor(Color.BLUE);

    ShapeDrawable smallerCircle= new ShapeDrawable( new OvalShape());
    smallerCircle.setIntrinsicHeight( 10 );
    smallerCircle.setIntrinsicWidth( 10);
    smallerCircle.setBounds(new Rect(0, 0, 10, 10));
    smallerCircle.getPaint().setColor(Color.BLACK);
    smallerCircle.setPadding(50,50,50,50);

    LayerDrawable composite1 = new LayerDrawable(new Drawable[] biggerCircle,smallerCircle,});

但是没有工作，发生的是较小的圈子与较大的圈子一样大。所以唯一显示的就是黑圈与大圆的大小。
如果有人能帮忙，我会厌恶感谢提前。

But that didnt work, what happens is that the smaller circle get as big as the the bigger circle. So the only thing showing is as black circle with the size of the biggerCircle. I would apriciate if someone could help. Thanks in advance.

推荐答案

更改订单

Drawable[] d = {smallerCircle,biggerCircle};

LayerDrawable composite1 = new LayerDrawable(d);

尝试这样

        ShapeDrawable biggerCircle= new ShapeDrawable( new OvalShape());
        biggerCircle.setIntrinsicHeight( 60 );
        biggerCircle.setIntrinsicWidth( 60);
        biggerCircle.setBounds(new Rect(0, 0, 60, 60));
        biggerCircle.getPaint().setColor(Color.BLUE);

        ShapeDrawable smallerCircle= new ShapeDrawable( new OvalShape());
        smallerCircle.setIntrinsicHeight( 10 );
        smallerCircle.setIntrinsicWidth( 10);
        smallerCircle.setBounds(new Rect(0, 0, 10, 10));
        smallerCircle.getPaint().setColor(Color.BLACK);
        smallerCircle.setPadding(50,50,50,50);
        Drawable[] d = {smallerCircle,biggerCircle};

        LayerDrawable composite1 = new LayerDrawable(d);

        btn.setBackgroundDrawable(composite1);
