使用 adb 向 Android 手机发出捏合/捏合命令

到目前为止，我可以使用 adb 命令点击、滑动、解锁、安装/卸载和启动应用程序，但无法找到如何使用 adb 命令执行放大/缩小。

我已经获得了捏入/捏出的坐标，但不知道如何使用终端的 adb 命令来触发它们。

例如，我们有命令 --> adb shell input tap x y 所以在这里我们可以用值/坐标替换 x 和 y 类似地我想知道模拟捏合/捏合的方法。

我获得的捏合坐标如下。

你可以使用adb getevent and sendevent.
使用以下方式连接您的设备adb。请按照以下步骤操作。

1. 识别您的输入设备：
   打开设备上的任何图像。要列出输入设备，请运行

   $ adb shell getevent   
   add device 1: /dev/input/event7   
   name:     "msm8226-tapan9302-snd-card Headset Jack"
   add device 2: /dev/input/event6
     name:     "msm8226-tapan9302-snd-card Button Jack"
   add device 3: /dev/input/event2
     name:     "synaptics_dsx_i2c"
   add device 4: /dev/input/event4
     name:     "qpnp_pon"
   

   在图像上捏合/张开，您应该看到一些连续的日志，例如

   /dev/input/event2: 0003 0030 00000005
   /dev/input/event2: 0000 0000 00000000
   /dev/input/event2: 0003 002f 00000000
   /dev/input/event2: 0003 0036 00000144
   /dev/input/event2: 0003 003a 00000079
   /dev/input/event2: 0000 0000 00000000
   /dev/input/event2: 0003 0036 00000142
   

   确认/dev/input/event2是我的目标设备的输入设备名称。

2. 得到准确的getevent并转换getevent to sendevent:

   确保您的屏幕已打开并且打开并显示一些图像，
   在提示符下运行以下命令。

   $ adb shell getevent | grep dev/input/event2 > getevent_input.txt
   

   当上面的命令运行时，在手机上的图像上捏合/张开。

   Once completed, Kill the above command Ctrl + C
   Open file getevent_input.txt and delete first line "add device X: /dev/input/eventX" from it.

   Since getevent返回十进制值，并且sendevent取十六进制值。
   我们要做上面的转换。
   这个脚本hex_to_dec.py http://pastebin.com/W3jNzPsv工作就在这里完成。谢谢this http://qatesttech.wordpress.com/2012/06/21/turning-the-output-from-getevent-into-something-something-that-can-be-used/ guy!

   $./hex_to_dec.py  getevent_input.txt 
   

   生成一个文件getevent_input.scr，现在将此文件重命名为.sh

   $ mv getevent_input.scr  sendevent_input.sh
   

   打开文件sendevent_input.sh并删除第二行"echoing – drawing function"并保存它。

3. 在设备上运行。
   转移sendevent_input.sh到设备。

   $ adb push sendevent_input.sh /sdcard/
   1615 KB/s (64379 bytes in 0.038s)
   

   确保您的设备已打开图像，并且屏幕未关闭。

   $ adb shell sh /sdcard/sendevent_input.sh
   

对我来说效果很好，如果这就是您所寻找的。
