C'è un modo per ottenere il layout e le visualizzazioni delle attività correnti tramite adb?

Question

Per motivi ambientali, posso utilizzare solo i comandi adb.

C'è un modo per ottenere layout corrente attributi come id, position, text ecc ?

Answer 1

Uso adb shell uiautomator dump comando:

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 

Di default discariche la vista gerarchia per $EXTERNAL_STORAGE/window_dump.xml

adb shell uiautomator dump 
UI hierchary dumped to: /sdcard/window_dump.xml 

Di solito si vorrebbe tirare quel file sul PC per ulteriori elaborazioni che sarebbe un extra passo. Ma c'è un trucco preciso che consente di combinare il dumping e il tiro in un unico comando. Utilizzando /dev/tty come destinazione discarica sarebbe stato un unico comando che stampare l'intera discarica al 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 

Answer 2

adb pull $(adb shell uiautomator dump | grep -oP '[^ ]+.xml') /tmp/view.xml 

Aprire /tmp/view.xml in un browser web come:

google-chrome /tmp/view.xml 

exec adb -out scarico uiautomator/dev/tty

dall'altra risposta non ha funzionato per me.

Answer 3

Ho usato il seguente su un Mac per la stampa in formato XML per la console:

adb shell uiautomator dump && adb pull /sdcard/window_dump.xml $TMPDIR && more $TMPDIR/window_dump.xml | xmllint --format -

Potrebbe essere necessario modificare il percorso del file /sdcard/window_dump.xml a tirare in base a dove viene scaricato il file xml.

AndroidViewClient/culebra Lo strumento dump consente di fare esattamente questo. AndroidViewClient può essere utilizzato come libreria e fornisce anche alcuni strumenti come dump e 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 

esecuzione dump senza opzioni, si limita a stampare l'albero di Vista e alcune delle sue proprietà di base, come 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 

d'altra parte, se si desidera che le posizioni dei punti di vista, si può essere eseguito

$ discarica -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)
