How can I use appium to find a element not visiable in a listview .driver.scroll_findElement_byname? - python-appium

Question

How can I use appium to find a element which is not visible in a listview (maybe the element are located in the bottom,and I need to scroll many pages so that i can find the element )
I have used driver.scroll_find_element_by_name() ,but I got a error.
Appium:info: [debug] Didn't get a new command in 60 secs, shutting
down...
My code is as follows:
def scroll_find_element_by_name(self, element_name, time_wait=0.5):
'''
#param：
#rtn： True/False，
#usage：
'''
#
width,height=self.getScreenResolution()
for i in range(maxScrollTimes):
#
try:
self.assertRaises(NoSuchElementException, self.driver.find_element_by_name, element_name)
print "Scroll down " + str(i+1) + ' time to find ' + element_name
except:
print 'SUCCESS: ' + element_name + ' found'
return True
self.driver.swipe(width / 2, 5 * height / 8, width / 2, 3 * height / 8, 1500)#
sleep(time_wait)
print 'UNSUCCESS: ' + element_name + 'NOT found'
return False

For iOS:
el = self.driver.find_element_by_xpath('xpath_value')
self.driver.execute_script('mobile: scroll', {"element": el, "toVisible": True})
Modify 'find_element_by_xpath' to id or whatever you want it to be.
For Android:
I have written my own custom method which looks for the element - if found it will click else move further down. get_element in the below code snippet is one of my own custom method, you should change it to find_elemeny_by_xpath / id etc. Modify it to suit your needs.
def android_is_visible(self, locator):
for _ in xrange(15):
end_y = 950
try:
value = self.get_element(locator).is_displayed()
if value is True:
break
except NoSuchElementException:
self.driver.swipe(470, 1400, 470, end_y, 400)
#self.driver.swipe(start_x, start_y, end_x, end_y, duration=400)
self.driver.implicitly_wait(2)
continue
Also change value of 'end_y = 950' as per your screen size
