问题
For environment reasons I can only use adb commands.
Is there a way to get the current layout attributes like id, position, text etc ?
Similar to what uiautomatorviewer shows.
回答1:
Use adb shell uiautomator dump command:
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
By default it dumps the views hierarchy to $EXTERNAL_STORAGE/window_dump.xml
adb shell uiautomator dump
UI hierchary dumped to: /sdcard/window_dump.xml
Usually you would want to pull that file to your PC for further processing which would be an extra step. But there is a neat trick which allows to combine dumping and pulling into a single command. Using /dev/tty as a dump destination would make a single command which would print the whole dump to the 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

AndroidViewClient/culebra's dump tool lets you do precisely that. AndroidViewClient can be used as a library and also provides some tools like dump and culebra.
usage: dump [OPTION]... [serialno]
Options:
-H, --help prints this help
-V, --verbose verbose comments
-v, --version
-I, --ignore-secure-device ignore secure device
-E, --ignore-version-check ignores ADB version check
-F, --force-view-server-use force view server use (even if UiAutomator present:w)
-S, --do-not-start-view-server don't start ViewServer
-k, --do-not-ignore-uiautomator-killed don't ignore UiAutomator killed
-w, --window=WINDOW dump WINDOW content (default: -1, all windows)
-a, --all dump all information about Views
-i, --uniqueId dump View unique IDs
-x, --position dump View positions
-b, --bounds dump View bounds
-d, --content-description dump View content descriptions
-g, --tag dump View tags
-c, --center dump View centers
-f, --save-screenshot=FILE save screenshot to file
-W, --save-view-screenshots=DIR save View screenshots to files in directory
-D, --do-not-dump-views don't dump views, only useful if you specified -f or -W
-A, --device-art=MODEL device art model to frame screenshot (auto: autodetected)
-Z, --drop-shadow drop shadow for device art screenshot
-B, --glare screen glare over screenshot
-h, --use-uiautomator-helper use UiAutomatorHelper Android app
-X, --debug=LIST debug options
running dump with no options, just prints the tree of Views and some of its basic properties, like ID
android.widget.FrameLayout
com.android.launcher3.Workspace com.google.android.apps.nexuslauncher:id/workspace
android.widget.FrameLayout com.google.android.apps.nexuslauncher:id/workspace_blocked_row
android.widget.TextView com.google.android.apps.nexuslauncher:id/date_text1 May 1
android.widget.TextView com.google.android.apps.nexuslauncher:id/date_text2 MONDAY, 2017
android.widget.TextView Maps
android.widget.ImageView com.google.android.apps.nexuslauncher:id/g_icon
android.widget.ImageView com.google.android.apps.nexuslauncher:id/all_apps_handle
android.view.ViewGroup com.google.android.apps.nexuslauncher:id/layout
android.widget.TextView Messenger
android.widget.TextView Chrome
on the other hand, if you want the positions of the views, you can run
$ dump -x
android.widget.FrameLayout (0, 0, 1440, 2392)
com.android.launcher3.Workspace com.google.android.apps.nexuslauncher:id/workspace (0, 0, 1440, 2392)
android.widget.FrameLayout com.google.android.apps.nexuslauncher:id/workspace_blocked_row (30, 126, 1380, 372)
android.widget.TextView com.google.android.apps.nexuslauncher:id/date_text1 May 1 (1037, 194, 337, 162)
android.widget.TextView com.google.android.apps.nexuslauncher:id/date_text2 MONDAY, 2017 (1092, 356, 282, 73)
android.widget.TextView Maps (30, 1614, 276, 372)
android.widget.ImageView com.google.android.apps.nexuslauncher:id/g_icon (30, 214, 276, 196)
android.widget.ImageView com.google.android.apps.nexuslauncher:id/all_apps_handle (636, 1986, 168, 98)
android.view.ViewGroup com.google.android.apps.nexuslauncher:id/layout (0, 2084, 1440, 308)
android.widget.TextView Messenger (306, 2112, 276, 280)
android.widget.TextView Chrome (858, 2112, 276, 280)
The options will give you control over the output. You can get some more info here.
回答3:
adb pull $(adb shell uiautomator dump | grep -oP '[^ ]+.xml') /tmp/view.xml
Open /tmp/view.xml in a web browser like:
google-chrome /tmp/view.xml
adb exec-out uiautomator dump /dev/tty
from the other answer didn't work for me.
回答4:
I used the following on a Mac to print formatted xml to the console:
adb shell uiautomator dump && adb pull /sdcard/window_dump.xml $TMPDIR && more $TMPDIR/window_dump.xml | xmllint --format -
You may need to change the path of the /sdcard/window_dump.xml file to pull based on where the xml file is dumped.
回答5:
Use the following to view the xml layout in notepad or your default text editor
adb shell uiautomator dump && adb pull /sdcard/window_dump.xml && start window_dump.xml
