c#写类QQ界面

下面我用C#写了个类QQ界面

效果图：

下面来介绍实现过程：

一、首先放三个Button，Text分别为好友，朋友，陌生人,接着放一个ListView 再放一个ImageList设置其Items将图片加载到这个元素集合中

二、并设置ListView的属性LargeImageList为imagelist实现ImageList里面的图片集合与ListView相关联

三、好啦界面基本设计好现在来看后台代码。目标实现：点击Button按钮有不同缩放效果

 先认识两个函数：SendToBack()和BringToFront()函数

SendToBack() 将控件移到 Z 顺序的后面。
BringToFront()将控件移到 Z 顺序的前面

下面是完整代码不解释:

  private void Form1_Load(object sender, EventArgs e)
        {
            listView1.Clear();//将listView中的元素清空
            listView1.LargeImageList = imageList1;
            listView1.Items.Add("小张","小张",0);
            listView1.Items.Add("小李","小李",1);
            listView1.Items.Add("小王","小王",2);
            listView1.Items.Add("小周","小周",3);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            listView1.Dock = DockStyle.None;
            button1.Dock = DockStyle.Top;
            button3.Dock = DockStyle.Bottom;
            button2.SendToBack();
            button2.Dock = DockStyle.Bottom;
            listView1.BringToFront();
            listView1.Dock = DockStyle.Bottom;
            listView1.Clear();
            listView1.LargeImageList = imageList1;
            listView1.Items.Add("小张", "小张", 0);
            listView1.Items.Add("小李", "小李", 1);
            listView1.Items.Add("小王", "小王", 2);
            listView1.Items.Add("小周", "小周", 3);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            listView1.Dock = DockStyle.None;
            button2.Dock = DockStyle.Top;
            button1.SendToBack();
            button1.Dock = DockStyle.Top;
            button3.Dock = DockStyle.Bottom;
            listView1.Dock = DockStyle.Bottom;
            listView1.Clear();
            listView1.Items.Add("小周","小周",3);
            listView1.Items.Add("小罗","小罗",4);
            listView1.Items.Add("小花","小花",5);
        }

        private void button3_Click(object sender, EventArgs e)
        {
            listView1.Dock = DockStyle.None;
            button3.SendToBack();
            button3.Dock = DockStyle.Top;
            button2.SendToBack();
            button2.Dock = DockStyle.Top;
            button1.SendToBack();
            button1.Dock = DockStyle.Top;
            listView1.Dock = DockStyle.Bottom;
            listView1.Clear();
            listView1.Items.Add("小张","小张",0);
            listView1.Items.Add("小王","小王",2);
            listView1.Items.Add("小罗","小罗",4);
        }
