问题描述
我想延长MonkeyDevice类monkeyrunner的API。
我的派生类看起来是这样的。
I would like to extend the MonkeyDevice class of the monkeyrunner API.My derived class looks like this.
from com.android.monkeyrunner import MonkeyDevice, MonkeyRunner
class TestDevice(MonkeyDevice):
def __init__(self, serial=None):
MonkeyDevice.__init__(self)
self = MonkeyRunner.waitForConnection(deviceId=serial)
self.serial = serial
当我称之为 test_dev =为TestDevice（串行）从另一个模块，我得到了以下错误：
When I call test_dev = TestDevice(serial) from another module I get the following error:
test_dev = TestDevice(serial)
TypeError: _new_impl(): 1st arg can't be coerced to com.android.monkeyrunner.core.IMonkeyDevice
我在做什么错了？
What am I doing wrong?
在此先感谢！
推荐答案
看样子你不能直接初始化 MonkeyDevice 实例，而不到一个工厂函数的调用为waitForConnection 。因此，你需要指定自在 __新__（）功能，使 MonkeyDevice 识别实例从 IMonkeyDevice 继承你打电话之前它的 __的init __
It appears you cannot directly initialize a MonkeyDevice instance without a call to a factory function waitForConnection. So instead you need to assign self in your __new__() function so that MonkeyDevice recognizes the instance as inheriting from IMonkeyDevice before you call it's __init__
例如：
class TestDevice(MonkeyDevice):
def __new__(self, serial=None):
return MonkeyRunner.waitForConnection(deviceId=serial)
def __init__(self):
MonkeyDevice.__init__(self)
