出于環境原因，我只能使用adb命令。有沒有一種方法來獲得當前的布局屬性，如id，position，text等？與uiautomatorviewer顯示的相似。

使用adb shell uiautomator dump命令：
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
/storage/emulated/legacy/window_dump.xml
events: prints out accessibility events until terminated
默認情況下，它會將視圖層次結構轉儲到 $EXTERNAL_STORAGE/window_dump.xml
adb shell uiautomator dump
UI hierchary dumped to: /sdcard/window_dump.xml
通常，您可能希望將該文件提取到PC進行進一步處理，這將是一個額外的步驟。但是有一個巧妙的技巧，它允許將轉儲和拉入組合成一個命令。使用/dev/tty轉儲目標將生成一個命令，將整個轉儲打印到stdout：
adb exec-out uiautomator dump /dev/tty
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?><hierarchy rotation="0"><node ...></node></hierarchy>UI hierchary dumped to: /dev/tty
