带有按钮单击的径向菜单android？ [关闭]

Question

我想设计这样的菜单。

我尝试过动画，但它不保留按钮的位置。

如果有人做过这种类型的菜单，请指导我。

任何帮助将不胜感激。

我最近创建了这个圆形菜单以添加到我最近的项目中。看起来像

您需要创建一个新视图并绘制此视图，检查用户输入（他正在触摸的位置），设计一个反馈机制，例如，在我看来，如果用户触摸了 5 个弧中的任何一个，背景颜色变为天蓝色。这是我的 onDrawMethod 代码。

protected void onDraw(Canvas canvas) {
        // TODO Auto-generated method stub

        px = getMeasuredWidth()/2;     
        py = getMeasuredHeight();


        initial = 144;
        finalangle = 252;

        centerCircleradius  = 30;
        middleCircleRadius = 140;




            int init, fina;
            init = 160;    
            fina = 360;
            finalOVal.set(px-middleCircleRadius-4, py-middleCircleRadius-4, px+middleCircleRadius+4, py+middleCircleRadius+4);
            middleOval.set(px-middleCircleRadius, py-middleCircleRadius, px+middleCircleRadius, py+middleCircleRadius);
            while(init<fina)
            {
                circlePaint.setColor(colors[i]);
                canvas.drawArc(finalOVal,init,10,false, circlePaint);
                i++;
                if(i>=colors.length)
                {
                    i=0;
                }
                init = init + 10;

            }



            canvas.drawArc(middleOval, 180, 180, false, pencil);

            midInitial = 180;


            i=0;

            //Creating the first Arc
            if(arcTouched[0])
            {

                canvas.drawArc(middleOval, midInitial, 36, true, arcTouchedBack);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            else
            {
                canvas.drawArc(middleOval, midInitial, 36, true, middleCircleBody);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            canvas.drawBitmap(bitmap.get(0), null, (putBitmapTo(midInitial, 36, 140, px, py)), null);
            midInitial+=36;

            if(arcTouched[1])
            {

                canvas.drawArc(middleOval, midInitial, 36, true, arcTouchedBack);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            else
            {
                canvas.drawArc(middleOval, midInitial, 36, true, middleCircleBody);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            canvas.drawBitmap(bitmap.get(1), null, (putBitmapTo(midInitial, 36, 140, px, py)), null);
            midInitial+=36;

            if(arcTouched[2])
            {

                canvas.drawArc(middleOval, midInitial, 36, true, arcTouchedBack);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            else
            {
                canvas.drawArc(middleOval, midInitial, 36, true, middleCircleBody);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            canvas.drawBitmap(bitmap.get(2), null, (putBitmapTo(midInitial, 36, 140, px, py)), null);
            midInitial+=36;
            //Creatring the second Arc

            if(arcTouched[3])
            {

                canvas.drawArc(middleOval, midInitial, 36, true, arcTouchedBack);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            else
            {
                canvas.drawArc(middleOval, midInitial, 36, true, middleCircleBody);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            canvas.drawBitmap(bitmap.get(3), null, (putBitmapTo(midInitial, 36, 140, px, py)), null);
            midInitial+=36;

            if(arcTouched[4])
            {

                canvas.drawArc(middleOval, midInitial, 36, true, arcTouchedBack);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            else
            {
                canvas.drawArc(middleOval, midInitial, 36, true, middleCircleBody);
                canvas.drawArc(middleOval, midInitial, 36, true, pencil);
            }
            canvas.drawBitmap(bitmap.get(4), null, (putBitmapTo(midInitial, 36, 140, px, py)), null);           
            canvas.drawCircle(px, py-10, 40, pencil);
            canvas.drawCircle(px, py-10, 39, smallCircleCore);

            canvas.drawCircle(px, py-10, 35, bigArc);
            canvas.drawCircle(px, py-10, 20, smallCircleCore);

            canvas.drawCircle(px, py-10, 15, bigArc);
            canvas.drawLine(px-8, py-10, px+8, py-10, lineCore);

        canvas.save();
    }

您可能需要的一些参考资料。

bitmap -> 是一个包含图片的数组列表

arcToched[] -> 是一个定义圆弧背景的数组，这个布尔数组的值在 onTouchEvent() 方法中被修改。

lineCore、smallCircleCore .....都是颜料。

我知道这不是最好的方法，也不专业。我根据需要创建了这个菜单。在您更改角度计算之前，它无法以某种方式缩放。

此视图深受 Catch Notes 应用程序的启发。我在创建这个视图时遇到的唯一麻烦是确定触摸的弧线。我在这里使用的唯一动画就像 Catch Notes 一样（圆形菜单扩展得比给定大小多一点，然后恢复正常）。
