如何从 adb shell 运行 UIAutomator2 命令？

Question

可能是一个愚蠢的问题，但我想验证答案是否定的：

可以在不启动检测测试类的情况下从adb shell 运行UIAutomator2 命令吗？

到目前为止，我似乎只能转储 XML 并对其进行解析，但我想知道我是否可以调用单个命令。

TLDR；不，对于UiAutomator2 拥有的几乎所有操作/可用方法，您都不能使用adb shell uiautomator xyzcommands。

运行adb shell uiautomator --help 将显示可用的子命令：

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

但是我发现这个对大多数（如果不是全部）adb 命令非常有用的要点：https://gist.github.com/Pulimet/5013acf2cd5b28e55036c82c91bd56d8

您还可以检查自己可以运行哪些命令：

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