使用adb向Android手机发出捏合/缩小命令

Question

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,但无法使用adb命令查找如何执行放大/缩小.

我有一些捏合进/出的坐标,但没有理解如何使用来自终端的adb命令来解雇它们.

例如,我们有命令 - > adb shell输入tap xy所以在这里我们可以用值/坐标替换x和y同样我想知道模拟插入/缩小的方法.

我得到的有关插入的坐标如下.

Answer 1

你可以用adb getevent和做sendevent.
使用连接设备adb.请按照以下步骤操作.

1. 识别输入设备:
   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"
   

   捏进/出图像,你应该看到一些连续的日志,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. 获取确切getevent并转换getevent为sendevent:

   确保您的屏幕已打开并打开某些图像,
   在提示符处运行以下命令.

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

   在上述操作正在运行时,请在手机上的图像上进行捏合.

   完成后,杀死上面的命令Ctrl+ C
   打开文件getevent_input.txt并"add device X: /dev/input/eventX"从中删除第一行.

   因为getevent返回值以十进制表示,并sendevent以十六进制取值.
   我们必须进行上述转换.
   这个脚本hex_to_dec.py在这里完成了Job.谢谢你这家伙!

   $./hex_to_dec.py  getevent_input.txt 
   

   生成文件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.

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)
   

   确保设备打开了图像,并且屏幕未关闭.

   $ adb shell sh /sdcard/sendevent_input.sh
   

对我来说工作得非常好,如果这就是你要找的东西.
要获得可见结果,请Show touches在Developer Options中启用.
