为啥我要做这个东西了，是因为经常要用投影演示app ，现在有很多这样的软件可以把手机界面投到电脑上 ，但都要安装，比如说360的手机助手，我又讨厌安装，于是就自己捣鼓了下 做了这个东西，
实现了以下简单功能
1、屏幕获取（因为是截图方式获取的，所以有点卡顿）
2、实现点击功能，并在点击的时候出现一个手势图标，方便用户观看
3、实现简单的滑动功能
4、实现在界面上画图功能
5、实现拖拽安装apk功能
操作说明：鼠标左边 模拟手机点击，中键停止/开始刷新界面（画图的时候不能刷新），右键去掉画图内容
显示来看下效果图
这个就是主界面了，下面有显示手机型号
其次是在上面画图功能方便讲解
原理就是通过abd来实现的
adb shell input keyevent 26 点击power
这是截屏显示图片的代码
1 private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)View Code
2 {
3 while (true)
4 {
5 if (isStop)
6 {
7 return;
8 }
9 //死循环截屏获取图片
10 var tempFileName = "1.png";
11 cmdAdb("shell screencap -p /sdcard/" + tempFileName);
12 // pictureBox1.ImageLocation = Environment.CurrentDirectory + "\\temp\\" + tempFileName;
13 cmdAdb("pull /sdcard/" + tempFileName);
14 if (System.IO.File.Exists(tempFileName))
15 {
16 //pictureBox1.BackgroundImage = new Bitmap(tempFileName);
17 using (var temp = Image.FromFile(tempFileName))
18 {
19
20 pictureBox1.Invoke(new Action(() => {
21 pictureBox1.Image = new Bitmap(temp);
22 }));
23 }
24 if (multiplierX == 0)
25 {
26 multiplierX = pictureBox1.Image.Width / (pictureBox1.Width + 0.00);
27 multiplierY = pictureBox1.Image.Height / (pictureBox1.Height + 0.00);
28 }
29 GC.Collect();
30 if (System.IO.File.Exists(tempFileName))
31 {
32 try
33 {
34 System.IO.File.Delete(tempFileName);
35 }
36 catch
37 {
38
39 }
40 }
41 Thread.Sleep(1000);
42
43 }
44 }
45 }
这个是画图点击以及滑动的代码
1 private void pictureBox1_MouseClick(object sender, MouseEventArgs e)View Code
2 {
3 if (e.Button == System.Windows.Forms.MouseButtons.Right)//鼠标右键 撤销画画
4 {
5 this.Refresh();
6 return;
7 }
8 if (e.Button == MouseButtons.Middle)//鼠标中键按下 停止或开始更新图像
9 {
10 isStop = !isStop;
11 if (!isStop && HasAndroid)
12 {
13 backgroundWorker1.RunWorkerAsync();
14 }
15 return;
16 }
17 if (isDraw)
18 {
19 isDraw = false;
20 return;
21 }
22 if (pictureBox1.Image == null)
23 {
24 return;
25 }
26 using (Graphics g = pictureBox1.CreateGraphics())
27 {
28 g.DrawImage(ShowAndroidModel.Properties.Resources.shou, e.X - Convert.ToInt32(50 / multiplierX), e.Y - Convert.ToInt32(10 / multiplierY), Convert.ToInt32(150 / multiplierX), Convert.ToInt32(150 / multiplierY));
29 g.Dispose();
30 }
31 var tapx = multiplierX * e.X;//计算实际坐标
32 var tapy = multiplierY * e.Y;
33 cmdAdb(string.Format("shell input tap {0} {1}", tapx.ToString("0"), tapy.ToString("0")));//点击坐标
34 }
35
36 private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
37 {
38 if (e.Button == System.Windows.Forms.MouseButtons.Left)
39 {
40 lineStartX = e.X;
41 lineStartY = e.Y;
42 StartX = e.X;
43 StartY = e.Y;
44 _MouseState = MouseState.MouseLeftDown;
45 return;
46 }
47 }
48
49 private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
50 {
51 _MouseState = MouseState.None;
52 if (e.Button == System.Windows.Forms.MouseButtons.Left)
53 {
54 if (StartX - e.X > 50 || StartX - e.X < -50 || StartY - e.Y > 50 || StartY - e.Y < -50)
55 {
56 isDraw = true;
57 Debug.WriteLine("执行" + isDraw);
58 cmdAdb(string.Format("shell input swipe {0:0} {1:0} {2:0} {3:0} 100", StartX * multiplierX, StartY * multiplierY, e.X * multiplierX, e.Y * multiplierY));
59 }
60 }
61 }
62
63 private void pictureBox1_SizeChanged(object sender, EventArgs e)
64 {
65 multiplierX = pictureBox1.Image.Width / (pictureBox1.Width + 0.00);
66 multiplierY = pictureBox1.Image.Height / (pictureBox1.Height + 0.00);
67 }
68
69 private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
70 {
71 if (_MouseState == MouseState.None)
72 {
73 return;
74 }
75 if (_MouseState == MouseState.MouseLeftDown)
76 {
77 isDraw = true;
78 using (Graphics g = pictureBox1.CreateGraphics())
79 {
80 g.DrawLine(new Pen(Color.Red, 2), new Point(lineStartX, lineStartY), new Point(e.X, e.Y));
81 g.Dispose();
82 }
83
84 lineStartX = e.X;
85 lineStartY = e.Y;
86
87 return;
88 }
89 }
检测设备是否存在
1 /// <summary>
2 /// 检测是否存在手机
3 /// </summary>
4 private void CheckHasAndroidModel()
5 {
6 var text = cmdAdb("shell getprop ro.product.model",false);//获取手机型号
7 Debug.WriteLine("检查设备：" + text+" T="+DateTime.Now);
8 if (text.Contains("no devices")||string.IsNullOrWhiteSpace(text))
9 {
10 HasAndroid = false;
11 isStop = true;
12 toolStripStatusLabel2.Text="未检测到设备";
13 }
14 else
15 {
16 HasAndroid = true;
17 isStop = false;
18 toolStripStatusLabel2.Text = text.Trim();
19 if (!backgroundWorker1.IsBusy)
20 {
21 backgroundWorker1.RunWorkerAsync();
22 }
23 }
24 }
重写WndProc方法监听usb设备插入
1 protected override void WndProc(ref Message m)View Code
2 {
3 if (m.Msg == 0x219)
4 {
5 Debug.WriteLine("WParam：{0} ,LParam:{1},Msg：{2}，Result：{3}", m.WParam, m.LParam, m.Msg, m.Result);
6 if (m.WParam.ToInt32() == 7)//设备插入或拔出
7 {
8 CheckHasAndroidModel();
9 myTimer.Start();
10 }
11 }
12 try
13 {
14 base.WndProc(ref m);
15 }
16 catch { }
17 }
