请问java中设置线形为虚线的函数是哪个？

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);

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

用你的方法解决了
thank Acylas a lot!

好像没有吧，可以自己实现一下Graphics.drawLine();

[Acylas]

g2d.setStroke

[augustfox]

setStroke只是设置线的宽度啊！
