如何從 adb shell 運行 UIAutomator2 命令？

Question

可能是一個愚蠢的問題，但我想驗證答案是否定的：

可以在不啟動儀器測試 class 的情況下從adb shell運行UIAutomator2命令嗎？

到目前為止，我似乎所能做的就是轉儲 XML 並解析它，但我想知道我是否可以調用單個命令。

TLDR； 不，對於UiAutomator2具有的幾乎所有操作/可用方法，您不能使用adb shell uiautomator xyzcommands 。

運行adb shell uiautomator --help將顯示可用的子命令：

adb shell uiautomator --help
Usage: uiautomator <subcommand> [options]

Available subcommands:

help: displays help message

runtest: executes UI automation tests
    runtest <class spec> [options]
    <class spec>: <JARS> < -c <CLASSES> | -e class <CLASSES> >
      <JARS>: a list of jar files containing test classes and dependencies. If
        the path is relative, it's assumed to be under /data/local/tmp. Use
        absolute path if the file is elsewhere. Multiple files can be
        specified, separated by space.
      <CLASSES>: a list of test class names to run, separated by comma. To
        a single method, use TestClass#testMethod format. The -e or -c option
        may be repeated. This option is not required and if not provided then
        all the tests in provided jars will be run automatically.
    options:
      --nohup: trap SIG_HUP, so test won't terminate even if parent process
               is terminated, e.g. USB is disconnected.
      -e debug [true|false]: wait for debugger to connect before starting.
      -e runner [CLASS]: use specified test runner class instead. If
        unspecified, framework default runner will be used.
      -e <NAME> <VALUE>: other name-value pairs to be passed to test classes.
        May be repeated.
      -e outputFormat simple | -s: enabled less verbose JUnit style output.

dump: creates an XML dump of current UI hierarchy
    dump [--verbose][file]
      [--compressed]: dumps compressed layout information.
      [file]: the location where the dumped XML should be stored, default is
      /sdcard/window_dump.xml

events: prints out accessibility events until terminated

但是我發現這個非常有用的 Gist 與大多數（如果不是全部） adb命令： https://gist.github.com/Pulimet/5013acf2cd5b28e55036c82c91bd56d8

您還可以檢查自己可以運行哪些命令：

adb shell toybox --long | tr " " "\n"
