Question

我正在尝试制作ShapeDrawable但是当我调整它时，Android会画出一条模糊的线条。我知道一些示例代码说这不会发生，所以我无法理解我做错了什么。这就是我写的：

Path pathTriangulo = new Path();
pathTriangulo.moveTo(0, 0);
pathTriangulo.lineTo(50, 0);
pathTriangulo.lineTo(50, 50);
pathTriangulo.lineTo(0, 0);
miImagen = new ShapeDrawable(new PathShape(pathTriangulo,50,50));
miImagen.getPaint().setColor(Color.BLACK);
miImagen.getPaint().setStyle(Paint.Style.STROKE);
miImagen.setBounds(0, 0, 5000, 5000);

如果我写miImagen.setBounds(0,0,50,50)它完美无缺：/ 如果你能帮助我，我将不胜感激！

你的shapesrawable应该覆盖onBoundsChange（）并根据边界创建一个新的PathShape。使用setShape（）将新的PathShape应用于您的可绘制的

    miImagen = new ShapeDrawable(new PathShape(pathTriangulo,50,50)) {
        @Override
        protected void onBoundsChange(Rect bounds) {
            super.onBoundsChange(bounds);
            Path pathTriangulo = new Path();
            pathTriangulo.moveTo(0, 0);
            pathTriangulo.lineTo(50, 0);
            pathTriangulo.lineTo(50, 50);
            pathTriangulo.lineTo(0, 0);
            setShape( new PathShape(pathTriangulo, bounds.width(), bounds.height()));

        }
    };
