Hospital Appointment Booking (医联 / Yilian)

Automate doctor appointment booking on the 医联 Android app (com.wonders.mobile.app.yilian). The app uses native Android views (no UC WebView issues). Use uiautomator2 for all interactions — Appium is NOT needed.

Before Any Action

import uiautomator2 as u2
d = u2.connect()

Kill 12306 first if running — both apps can't share the accessibility service:

import subprocess
subprocess.run(["adb", "shell", "am", "force-stop", "com.MobileTicket"])

Launch 医联:

subprocess.run(["adb", "shell", "monkey", "-p", "com.wonders.mobile.app.yilian",
                "-c", "android.intent.category.LAUNCHER", "1"])
import time; time.sleep(5)

App Info

⚠️ Key Technical Constraints

Chinese Text Input: Use set_text()

d.send_keys("华山医院") fails (clipboard permission denied). adb shell input text fails (NullPointerException on Chinese chars). Use set_text() instead:

# Focus the field, then set text via AccessibilityService ACTION_SET_TEXT
el = d(className='android.widget.EditText')
el.click()         # focus first
time.sleep(0.5)
el.set_text("华山医院")  # bypasses IME/clipboard entirely

This works because set_text() uses the Android AccessibilityService's ACTION_SET_TEXT action, which directly injects text into the focused EditText without needing an IME or clipboard permissions.

Element Clickability

Many department/button TextViews have clickable=false. Their parent container (LinearLayout/FrameLayout) has clickable=true. Always check parent containers by bounds containment:

for p in root.iter('node'):
    if p.get('clickable') == 'true' and parent_bounds_contains(p, child_bounds):
        # This is the actual clickable target

Schedule Data Loading Delay

The SchedulingActivity`` RecyclerView takes **2-10 seconds** to populate with available dates. After tapping a slot, poll the dump for date texts like "2026-06-01"` until they appear.

Screen Reading

Primary: uiautomator2 dump_hierarchy + XML parsing

xml = d.dump_hierarchy()
root = __import__('xml.etree.ElementTree', fromlist=['ElementTree']).fromstring(xml.encode())

Helper: find clickable elements with text

import re
for node in root.iter('node'):
    text = node.get('text', '').strip()
    bounds = node.get('bounds', '')
    clickable = node.get('clickable')
    if text and clickable == 'true':
        nums = re.findall(r'\d+', bounds)
        if len(nums) >= 4:
            h = int(nums[3]) - int(nums[1])
            if h > 20:  # meaningful height
                print(f"'{text}' at {bounds}")

Helper: find clickable parent by bounds

def find_clickable_parent(root, child_bounds):
    child_nums = __import__('re').findall(r'\d+', child_bounds)
    if len(child_nums) \x3C 4: return None
    cx1, cy1, cx2, cy2 = int(child_nums[0]), int(child_nums[1]), int(child_nums[2]), int(child_nums[3])
    for p in root.iter('node'):
        if p.get('clickable') != 'true': continue
        pn = __import__('re').findall(r'\d+', p.get('bounds', ''))
        if len(pn) >= 4:
            px1, py1, px2, py2 = int(pn[0]), int(pn[1]), int(pn[2]), int(pn[3])
            if px1 \x3C= cx1 and py1 \x3C= cy1 and px2 >= cx2 and py2 >= cy2:
                return p
    return None

Fallback: Screenshot + OCR

d.screenshot('/tmp/screen.png')
import pytesseract
from PIL import Image
text = pytesseract.image_to_string(Image.open('/tmp/screen.png'),
    lang='chi_sim', config='--psm 6')

Booking Flow

Step 1: Home Page — Search for Hospital

Home page UI:

• "搜医院、科室、医生" — search box (clickable) at top
• "当日挂号" — same-day appointments
• "预约挂号" — appointment booking label (NOT clickable)

d(text='搜医院、科室、医生').click()
time.sleep(2)

On the search page, type the hospital name:

el = d(className='android.widget.EditText')
el.click()
time.sleep(0.5)
el.set_text("华山医院")  # set text via AccessibilityService
time.sleep(2)            # wait for suggestions

After typing, the search results / suggestions appear. Tap the hospital card:

xml = d.dump_hierarchy()
if '华山医院' in xml:
    # Tap at hospital card position
    d.click(540, 1033)  # center of hospital card

Step 2: Hospital Card → Tap to Enter

On the search result page, tap the hospital card to go to its detail page:

# Look for the hospital card in the results
for node in root.iter('node'):
    if '华山医院' in node.get('text', ''):
        parent = find_clickable_parent(root, node.get('bounds', ''))
        # Tap parent's center
        ...

This navigates to HospitalHomePageActivity.

Step 3: Find "预约挂号" Icon

On the hospital detail page (HospitalHomePageActivity), there are icon buttons:

• 预约挂号 at column 2 (x: 270-540) in the first row
• 当日挂号 at column 3 (x: 540-810) in the first row

# The "预约挂号" icon is in the clickable container:
# Row 1: [0,1279][270,1522], [270,1279][540,1522], [540,1279][810,1522], [810,1279][1080,1522]
# Column 2 (270-540) = 预约挂号
d.click(405, 1400)  # center of second icon

This navigates to DepartmentActivity.

Step 4: Select Appointment Type Tab + Department

On DepartmentActivity:

• Tabs at top: "专家门诊", "专病门诊", "普通门诊" (text, NOT clickable — tap their clickable parent)
• Department list shows available departments

First select the appointment type tab, then tap the target department:

# Tap "普通门诊" tab
d.click(900, 516)  # center of third tab

# The department list refreshes. Now find "皮肤科":
xml = d.dump_hierarchy()
root = __import__('xml.etree.ElementTree', fromlist=['ElementTree']).fromstring(xml.encode())
for node in root.iter('node'):
    if node.get('text', '').strip() == '皮肤科':
        parent = find_clickable_parent(root, node.get('bounds', ''))
        if parent:
            nums = __import__('re').findall(r'\d+', parent.get('bounds', ''))
            cx = (int(nums[0]) + int(nums[2])) // 2
            cy = (int(nums[1]) + int(nums[3])) // 2
            d.click(cx, cy)

This may navigate to SpecialDiseaseActivity (department detail).

Step 5: Select Appointment Entry

On SpecialDiseaseActivity, find the appointment type entry for the department:

# Look for entries like "普通门诊-[医联平台] ¥25" with "有号" (available)
for node in root.iter('node'):
    t = node.get('text', '').strip()
    if '有号' in t or '普通门诊' in t:
        parent = find_clickable_parent(root, node.get('bounds', ''))
        if parent:
            # Tap to navigate to SchedulingActivity

Step 6: Select Date and Time Slot

On SchedulingActivity (activity == ".patient.ui.hospital.SchedulingActivity"):

The RecyclerView takes 2-10 seconds to populate. Poll for data:

# Wait for schedule data to load
for i in range(15):
    time.sleep(1)
    xml = d.dump_hierarchy()
    if '2026-06-01' in xml:  # target date appeared
        break

# Target date will show as: "2026-06-01  星期一 上午"
# Find its clickable parent and tap
root = __import__('xml.etree.ElementTree', fromlist=['ElementTree']).fromstring(xml.encode())
for node in root.iter('node'):
    if node.get('text', '').strip() == '2026-06-01  星期一 上午':
        parent = find_clickable_parent(root, node.get('bounds', ''))
        ...

This navigates to ReserveInfoActivity.

Step 7: Confirm Appointment

On ReserveInfoActivity, verify all details:

• 医院: 华山医院
• 科室: 皮肤科
• 类型: 普通门诊
• 就诊日期: 2026-06-01 星期一 上午
• 就诊时段: 07:45-08:00 (changeable by tapping)

Patient selection: tap the patient name to select/deselect. Captcha section:

• "获取验证码" — tap to request SMS code
• "请输入验证码" — tap to enter code
• "确定预约" at bottom — tap to finalize

SMS verification code is required — inform the user to check their phone.

# Tap 确定预约 after captcha is entered
d.click(540, 2292)

Common Pitfalls

1. 12306 conflict: Can't run both apps' automation simultaneously. Force-stop 12306 first.
2. Chinese text input: NOT supported via ADB. Use hot search suggestions or pre-existing text.
3. Schedule loading delay: RecyclerView populates asynchronously. Poll for date text (up to 15s).
4. Elements with clickable=false: TextViews may not be clickable — tap their parent container instead.
5. ADB disconnects: USB can drop. Run adb kill-server && adb start-server to recover.
6. SMS captcha: The user must enter the verification code manually.
7. Patient selection: Verify correct patient is checked before confirming.

Decision Tree

d.dump_hierarchy() + check activity:
  ├─ activity == "MainActivity" → HOME
  │   → tap search box → tap hot suggestion
  ├─ activity == "SearchActivity" → SEARCH RESULTS
  │   → tap hospital card
  ├─ activity == "HospitalHomePageActivity" → HOSPITAL PAGE
  │   → tap 预约挂号 icon (2nd icon, 1st row)
  ├─ activity == "DepartmentActivity" → DEPARTMENTS
  │   → select tab (普通门诊) → tap department name
  ├─ activity == "SpecialDiseaseActivity" → DEPT DETAIL
  │   → tap available appointment entry (有号)
  ├─ activity == "SchedulingActivity" → DATE PICKER
  │   → wait for data → tap target date/time slot
  ├─ activity == "ReserveInfoActivity" → CONFIRMATION
  │   → verify details → get SMS captcha → tap 确定预约
  └─ otherwise → unknown state, take screenshot
