请问java中设置线形为虚线的函数是哪个？谢谢

Question

好像没有吧，可以自己实现一下Graphics.drawLine();

Answer 1

setStroke只是设置线的宽度啊！

Answer 2

你看看BasicStroke
switch(m_nLineType)
            {
                case LINE_TYPE_DASHED:          fltDashMode=new float[]{16,4};          break;
                case LINE_TYPE_DOT:             fltDashMode=new float[]{2,6};           break;
                case LINE_TYPE_DOTDASHED:       fltDashMode=new float[]{2,4,30,4};      break;
                case LINE_TYPE_DOTDOTDASHED:    fltDashMode=new float[]{2,2,2,2,20,2};  break;
                case LINE_TYPE_PLAIN:           fltDashMode=null;                       break;
                default: return;
            }
new BasicStroke(1,BasicStroke.CAP_BUTT,BasicStroke.JOIN_BEVEL,0,fltDashMode,0);

Answer 3

我看了BasicStroke
里面的原型有public BasicStroke(float width, int cap, int join, float miterlimit) {
    this(width, cap, join, miterlimit, null, 0.0f);
    }public BasicStroke(float width, int cap, int join) {
    this(width, cap, join, 10.0f, null, 0.0f);
    } public BasicStroke(float width) {
    this(width, CAP_SQUARE, JOIN_MITER, 10.0f, null, 0.0f);
    }public BasicStroke() {
    this(1.0f, CAP_SQUARE, JOIN_MITER, 10.0f, null, 0.0f);
    }没有您说的switch(m_nLineType)啊
另外我用new BasicStroke(1,BasicStroke.CAP_BUTT,BasicStroke.JOIN_BEVEL,0,fltDashMode,0);
程序报错“不能解析fltDashMode”谢谢
