下面贴出githup上关于该方法的使用
1
Watcher
2
You can register watchers to perform some actions when a selector does
not
find a match.
3
4
Register Watcher
5
6
When a selector can
not
find a match, uiautomator2 will run all registered watchers.
7
8
Click target when conditions match
9
d.watcher(
"
AUTO_FC_WHEN_ANR
"
).when(text=
"
ANR
"
).when(text=
"
Wait
"
) \
10
.click(text=
"
Force Close
"
)
11
#
d.watcher(name) ## creates a new named watcher.
12
#
.when(condition) ## the UiSelector condition of the watcher.
13
#
.click(target) ## perform click action on the target UiSelector.
14
There
is
also a trick about click. You can use click without arguments.
15
16
d.watcher(
"
ALERT
"
).when(text=
"
OK
"
).click()
17
#
Same as
18
d.watcher(
"
ALERT
"
).when(text=
"
OK
"
).click(text=
"
OK
"
)
19
Press key when a condition becomes true
20
d.watcher(
"
AUTO_FC_WHEN_ANR
"
).when(text=
"
ANR
"
).when(text=
"
Wait
"
) \
21
.press(
"
back
"
,
"
home
"
)
22
#
d.watcher(name) ## creates a new named watcher.
23
#
.when(condition) ## the UiSelector condition of the watcher.
24
#
.press(
, ...,
.() ## press keys one by one in sequence.
25
Check
if
the named watcher triggered
26
27
A watcher
is
triggered, which means the watcher was run
and
all its conditions matched.
28
29
d.watcher(
"
watcher_name
"
).triggered
30
#
true in case of the specified watcher triggered, else false
31
Remove a named watcher
32
33
#
remove the watcher
34
d.watcher(
"
watcher_name
"
).remove()
35
List all watchers
36
37
d.watchers
38
#
a list of all registered watchers
39
Check
for
any triggered watcher
40
41
d.watchers.triggered
42
#
true in case of any watcher triggered
43
Reset all triggered watchers
44
45
#
reset all triggered watchers, after that, d.watchers.triggered will be false.
46
d.watchers.reset()
47
Remove watchers
48
49
#
remove all registered watchers
50
d.watchers.remove()
51
#
remove the named watcher, same as d.watcher("watcher_name").remove()
52
d.watchers.remove(
"
watcher_name
"
)
53
Force to run all watchers
54
55
#
force to run all registered watchers
56
d.watchers.run()
注：里面涉及的watcher_name可以自定义，可以做到见名知意即可
watcher的使用是要先注册（第9行至20行均是注册watcher的方法），然后激活watcher(第56行)，注意这个激活方法只是一个瞬时激活，就是说使用之后即销毁，不会一直存于后台。那这样的话在实际的使用场景中怎么使用这个功能呢，下面看一段脚本 1 # -*- coding:utf-8 -*-
