使用adb向Android手机发出捏合/缩小命令

时间：2014-08-18 12:39:38

标签： android adb

到目前为止，我可以使用adb命令点按，滑动，解锁，安装/卸载和启动应用，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 - ＆gt; adb shell输入tap x y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。

我收到的用于缩放的坐标位于下方。

答案 0 :(得分：17)

您可以使用adb getevent和sendevent执行此操作 使用adb连接您的设备。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/缩小，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是目标设备的输入设备名称。

  2. 准确getevent并将getevent转换为sendevent：

    确保您的屏幕已打开并打开一些图像，
    在提示符上运行以下命令。 

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

    当上述内容正在运行时，请在手机上的图像上进行捏合。

    完成后，杀死上述命令 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，sendevent取十六进制值 我们必须进行上述转换 这个脚本hex_to_dec.py在这里完成了Job。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并删除第二行"echoing – drawing function"并保存。

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

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

    确保设备打开了图像，屏幕未关闭。 

    $ adb shell sh /sdcard/sendevent_input.sh

    4. 对我来说工作得很好，如果这就是你要找的东西 要获得可见结果，请在“开发者选项”中启用Show touches。

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

答案 1 :(得分：1)

adb shell input的一种（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

我们的想法是我们启动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轻击+轻扫，因此执行缩放。 上面的示例是在地图上缩小。

答案 2 :(得分：0)

“一种（有点怪异的）解决方案...”在Ubuntu上对我有用，但是我无法在Windows中运行类似的东西。因此，我创建了一个脚本文件（在电话中，在/ data / local / tmp中），将该代码粘贴到此处（跳过“ adb shell”），将chmod粘贴到u + x，然后通过adb在Windows中执行。现在它可以在手机上使用了。
