android - 使用 adb 向 Android 手机发出捏合/捏合命令

Question

到目前为止，我能够使用 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。

我有捏合/捏合的坐标，但不明白如何从终端使用 adb 命令触发它们。

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

我得到的捏入坐标如下。

Answer 1

您可以使用 adb getevent 和 sendevent 来完成。
使用 adb 连接您的设备。按照以下步骤操作。

1. 识别您的输入设备:
   在您的设备上打开任何图像。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"
   

   放大/缩小图像，您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. 获取准确的getevent并将getevent转换为sendevent:

   确保您的屏幕已打开并打开了一些图像，
   在提示符下运行以下命令。

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

   当上述程序运行时，在您手机上的图像上捏合/捏合。

   完成后，终止上述命令 Ctrl + C
   打开文件 getevent_input.txt 并从中删除第一行 "add device X:/dev/input/eventX"。

   由于 getevent 返回十进制值，而 sendevent 获取十六进制值。
   我们要做上面的转换。
   此脚本 hex_to_dec.py这是工作。感谢this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，删除第二行"echoing – drawing function"并保存。

3. 在设备上运行。
   传输 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
   

对我来说非常好，如果这就是你要找的。
对于可见的结果，启用 Show touches在开发人员选项中。
