C#使用ListView更新数据出现闪烁解决办法
在使用vs自动控件ListView控件时候，更新里面的部分代码时候出现闪烁的情况
如图：
解决以后：
解决办法使用双缓冲：添加新类继承ListView 对其重写
public class DoubleBufferListView : ListView
{
public DoubleBufferListView()
{
SetStyle(ControlStyles.DoubleBuffer |
ControlStyles.OptimizedDoubleBuffer |
ControlStyles.AllPaintingInWmPaint, true);
UpdateStyles();
}
}
新建一个DemoTest测试
1.添加一个DoubleBufferListView的实例
DoubleBufferListView doubleBufferListView1= new DoubleBufferListView();
//
// doubleBufferListView1
//
this.doubleBufferListView1.Font = new System.Drawing.Font("微软雅黑", 10.5F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)()));
this.doubleBufferListView1.FullRowSelect = true;
this.doubleBufferListView1.HideSelection = false;
this.doubleBufferListView1.Location = new System.Drawing.Point(, );
this.doubleBufferListView1.Name = "doubleBufferListView1";
this.doubleBufferListView1.Size = new System.Drawing.Size(, );
this.doubleBufferListView1.TabIndex = ;
this.doubleBufferListView1.UseCompatibleStateImageBehavior = false;
this.doubleBufferListView1.View = System.Windows.Forms.View.Details;
2.将其添加到form窗体里面
this.Controls.Add(this.doubleBufferListView1);
3.给添加列
doubleBufferListView1.Clear();
doubleBufferListView1.Columns.Add("Action", , System.Windows.Forms.HorizontalAlignment.Left);
doubleBufferListView1.Columns.Add("value", , System.Windows.Forms.HorizontalAlignment.Right);
doubleBufferListView1.Columns.Add("Action", , System.Windows.Forms.HorizontalAlignment.Left);
doubleBufferListView1.Columns.Add("value", , System.Windows.Forms.HorizontalAlignment.Left);
4.随便添加点内容
string[] listViewData = new string[];
listViewData[] = "Action";
listViewData[] = "";
listViewData[] = "Action";
listViewData[] = "";
ListViewItem lvItem = new ListViewItem(listViewData, );
doubleBufferView1.Items.Add(lvItem);
5.点击按钮开始运行
private void button1_Click(object sender, EventArgs e)
{
Thread th = new Thread(PlayGame);
if (state == false)
{
state = true;
button1.Text = "停止";
th.IsBackground = true;
th.Name = "新线程";
th.Start();
}
else
{
state = false;
button1.Text = "开始"; }
}
private void PlayGame()
{
Random r = new Random();
while (state)
{
string temp = r.Next(, ).ToString();
label1.Text = temp;
this.doubleBufferListView1.Items[].SubItems[].Text = temp;
}
}
6.运行对比图：
左侧是解决闪屏后，右侧是自带的ListView效果
