I recently created this circular menu to add up in my recent project. It looks like
我最近创建了这个圆形菜单来添加到我最近的项目中。看起来像
What you need is to create a new View and draw this view, check for the user inputs (where he is touching), design a feedback mechanism, for example, in my view, if user touches any of the 5 arcs, background color changes to skyblue. Here is my code for onDrawMethod.
你需要的是创建一个新的视图并绘制这个视图，检查用户输入（他触摸的地方），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，背景颜色就会改变到天蓝色。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();
}
Some reference that you might need.
您可能需要的一些参考资料。
bitmap -> is an arraylist that contains images
bitmap -> 是一个包含图像的数组列表
arcToched[] -> is an array that defines the background for arc, the values of this boolean array gets modified in onTouchEvent() method.
arcToched[] -> 是一个定义弧背景的数组，这个布尔数组的值在 onTouchEvent() 方法中被修改。
lineCore, smallCircleCore ..... are paints.
lineCore、smallCircleCore ..... 是油漆。
I know this isn't the best way and not professional too. I created this menu as per need. Its not scale able in a way until you change the angle calculations.
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。
This view is highly inspired from Catch Notes Application. The only trouble I face in creating this view was to determine the arc touched. The only animation I used in here are just like again Catch Notes (the one in which circular menu extends a bit more than given size then gets back normal).
此视图的灵感来自 Catch Notes 应用程序。我在创建此视图时面临的唯一麻烦是确定所接触的弧。我在这里使用的唯一动画和 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）。
