使用 adb 向 Android 手机发送捏合/拉出命令答案

【问题标题】：Fire a pinch in/out command to Android phone using adb使用 adb 向 Android 手机发送捏合/拉出命令

【问题描述】：

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。

我有捏入/捏出的坐标，但不明白如何使用终端的 adb 命令触发它们。

例如，我们有命令 --> adb shell input tap x y 所以在这个我们可以用值/坐标替换 x 和 y 类似我想知道模拟捏合/拉出的方法。

我得到的捏合坐标如下。

【问题讨论】：

这看起来像Instrumentation。为什么不使用ActivityInstrumentationTestCase2 之类的东西，然后使用Instrumentation API 将MotionEvent 发送到您的Activity？
这样做的目的是什么？只是测试？如果是这样，您可以使用 Robotium，这是一个示例 link。您也可以使用批处理。看看link
我希望能够从终端本身触发 adb 命令。如果我没记错的话， Instrumentation 和 testcase2 与脚本有关，所以不想讨论这个。仍然如果@AntoineMarques，如果你有它的例子，请给我链接。
请参阅此处有关Instrumentation (developer.android.com/training/activity-testing/…) 的部分。我指的方法是developer.android.com/reference/android/app/…。那么，如果您还没有进行检测，本指南可能会对您有所帮助：developer.android.com/tools/testing/activity_test.html
@AntoineMarques 对于这些我需要脚本来运行，但我正在寻找的是使用输入点击 x y 等坐标来触发捏合/拉出的方法。仍然感谢您的回答。

【解决方案1】：

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

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"

在图像上捏入/捏出，您应该会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。

获取准确的getevent 并将getevent 转换为sendevent：

确保您的屏幕已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
```
在运行上述操作时，在手机上的图像上捏合/拉出。

一旦完成，杀死上面的命令Ctrl + C
打开文件getevent_input.txt 并从中删除第一行"add device X: /dev/input/eventX"。

因为getevent 返回十进制值，而sendevent 采用十六进制值。
我们必须进行上述转换。
这个脚本hex_to_dec.py 在这里完成了这项工作。感谢this家伙！
```
$./hex_to_dec.py  getevent_input.txt 
```
生成一个文件getevent_input.scr，现在将该文件重命名为.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。
在设备上运行。
将sendevent_input.sh 传输到设备。
```
$ 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
```

对我来说工作得很好，如果这是你要找的。
要获得可见的结果，请在开发人员选项中启用 Show touches。

环境：Motorola Moto G (Android 4.4.4) 与 ADB (v 1.0.31) 位于 Ubuntu 12.04。

【讨论】：

您的回答非常出色，但是在某些设备上 sendevent 真的很慢而且不起作用。
@Saurabh Meshram，我一步一步地按照你的回答，但似乎无法避免得到 sendevent: /dev/input/event2: Permission denied 执行时。这需要root权限吗？

【解决方案2】：

adb shell input 的（一种 hacky）解决方案看起来像

adb shell input tap 200 200 & PIDTAP=$!
sleep 0.1
adb shell input swipe 200 200 200 100 1000 & PIDSWIPE=$!
wait $PIDTAP
wait $PIDSWIPE

这个想法是我们启动 TAP 命令，然后短暂睡眠，然后执行 SWIPE。这样的命令序列被解释为点击 + 滑动，因此执行缩放。上面的例子是地图的缩小。

【讨论】：

对我不起作用 - 地图只是在晃动，向下移动
