If you want to do it from another tool, it's pretty easy. Run the
following commands from a shell:
Make sure you have a dev device/emulator (if you see 1, you're out of luck):
$ adb shell getprop ro.secure
0
Start the server:
$ adb shell service call window 1 i32 4939
You should see the following result (the 1 means the server is running):
Result: Parcel( 0001 '')
Install the port forwarding:
$ adb forward tcp:4939 tcp:4939
Connect to the server:
$ telnet localhost 4939
Now, you can use one of two commands (type enter after each command):
- LIST will show the list of windows:
LIST
43514758 com.android.launcher/com.android.launcher.Launcher
4359e4d0 TrackingView
435b00a0 StatusBarExpanded
43463710 StatusBar
43484c58 Keyguard
DONE.
- DUMP will show the views and their properties for a given window.
For instance, DUMP 43514758 will show the views contained in the
window com.android.launcher/com.android.launcher.Launcher. You can
also use DUMP -1 or DUMP to dump the foreground window. I
recommend that version. The dump may take a while go be generated and
it looks like this:
DUMP -1
com.android.internal.policy.impl.keyguardviewmanager$keyguardviewh...@434d8220

isInTouchMode()=4,true isSelected()=5,false
isSoundEffectsEnabled()=4,true willNotCacheDrawing()=5,false
willNotDraw()=4,true
...
DONE.
The format is simple. Each View is defined on a line of text which
ends with \n. The indent at the beginning of the line indicates the
depth of the child in the hierarchy. For instance, no indent == root,
1 space == child of the root, 2 spaces == child of a child of the
root, etc.
classn...@id followed by a list of properties. A property has the
following format: name=X,data where X is the number of characters in
the data.

You can look at the hierarchyviewer app. Note that this only works on dev
phones for security reasons.

Hello all,
Is there any way for an Android application to retrieve some sort
of Collection object that contains references to all of the GUI
elements which are currently on the phone's screen? This could be very
useful for testing purposes and so on.
If I have overlooked a well-known class or library, please let me
know.
Thanks.
