sendkeys其他输入框都能输入，只有这个不能输入，能够定位到输入框，能看得见光标显示了，无论是ID定位还是xpath定位最多也只是显示光标，有过一次手动输入几个字符后成功的输入进去了。贴代码
#输入手机号
account_name = driver.find_element_by_id('com.eestar:id/edtPhone').send_keys("15512341234")
#输入验证码
password = driver.find_element_by_id('com.eestar:id/edtCode').send_keys("1111")
#点击登录
driver.find_element_by_id("com.eestar:id/txtLogin").click()
#点击首页唯一直播
driver.find_element_by_id("com.eestar:id/txtTitle").click()
#输入聊天内容
time.sleep(5)
#a = 123
driver.find_element_by_id("com.eestar:id/txtChat").send_keys("3369")
光标能显示到输入框中，当时最终还是报错，只有这个一个输入框这样，是什么情况呢？
