android 自定义含有滚动选择器的对话框最近在写一个项目，需要用到滚动选择器，本人的想法是弹出一个对话框，中间包含滚动选择器，其中滚动选择器的源码参考的这篇文章http://blog.csdn.net/zhongkejingwang/article/details/38513301 先来看一下效果用滚动选择器选择分数，点击确定按钮，打分完成，点击取消按钮，对话框消失。关于自定义滚动选择器大家可以参考上面那篇文章，我觉得写的很容易阅读详情

如题，希望能具体点，急！

usb gadget uvc driver的code分析 uvc的linux driver分为host侧和gadget侧两个driver。host侧的driver在v4l2框架下，而设备侧的driver在usb/gadget文件夹下。gadget侧的uvc driver，利用v4l2框架去注册video_device，向应用层提供调用接口。同时，它完成v4l2 video buffer拷贝到usb request下的buffer下，然后利用uvc实现的协阅读详情

先在属性那里把对话框的滚动条沟上，比如勾上垂直滚动条。然后在对话框中生成OnVScroll事件。

void CIPictureDlg::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) //设置主窗口的滚动条
{
// TODO: Add your message handler code here and/or call default

SCROLLINFO scrollinfo;

GetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
switch (nSBCode)
{
case SB_BOTTOM:
ScrollWindow(0,(scrollinfo.nPos-scrollinfo.nMax)*10);
scrollinfo.nPos = scrollinfo.nMax;
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
break;
case SB_TOP:
ScrollWindow(0,(scrollinfo.nPos-scrollinfo.nMin)*10);
scrollinfo.nPos = scrollinfo.nMin;
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
break;
case SB_LINEUP:
scrollinfo.nPos -= 1;
if (scrollinfo.nPos)
{
scrollinfo.nPos = scrollinfo.nMin;
break;
}
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
ScrollWindow(0,10);
break;
case SB_LINEDOWN:
scrollinfo.nPos += 1;
if (scrollinfo.nPos>scrollinfo.nMax)
{
scrollinfo.nPos = scrollinfo.nMax;
break;
}
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
ScrollWindow(0,-10);
break;
case SB_PAGEUP:
scrollinfo.nPos -= 5;
if (scrollinfo.nPos)
{
scrollinfo.nPos = scrollinfo.nMin;
break;
}
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
ScrollWindow(0,10*5);
break;
case SB_PAGEDOWN:
scrollinfo.nPos += 5;
if (scrollinfo.nPos>scrollinfo.nMax)
{
scrollinfo.nPos = scrollinfo.nMax;
break;
}
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
ScrollWindow(0,-10*5);
break;
case SB_ENDSCROLL:
// MessageBox("SB_ENDSCROLL");
break;
case SB_THUMBPOSITION:
// ScrollWindow(0,(scrollinfo.nPos-nPos)*10);
// scrollinfo.nPos = nPos;
// SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
break;
case SB_THUMBTRACK:
ScrollWindow(0,(scrollinfo.nPos-nPos)*10);
scrollinfo.nPos = nPos;
SetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL);
break;
}
CDialog::OnVScroll(nSBCode, nPos, pScrollBar);
}

在使用之前，设置一下滚动条范围
SetScrollRange(SB_VERT,0, 100,1);
