This article is about how to use AccessibilityService to achieve Wechat account switching function automatically. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

I have been studying AccessibilityService for more than a month, and I found that its usage is actually quite simple, but it is more complicated to try and make mistakes in different projects.

Use AccessibilityService to automatically switch accounts on Wechat, as shown below (this step is all automatic):

The way to use it is to run the program-turn on the barrier-free service, switch to the main interface of Wechat, click the "I" tab button, and then automatically execute the logic of exiting the account and logging in again.

The basis of AccessibilityService usage:

Android auxiliary service category is mainly a tool to facilitate some users with obstacles to achieve barrier-free services, to put it bluntly, it can help these users to operate the device more easily, including text-to-voice, tactile feedback, gesture operation, trackball and handle operation.

You can also use this function to achieve a variety of strange functions, such as Wechat automatically grab red packets and other strange functions.

Based on the same principle, this paper realizes the function of automatically switching accounts. (in fact, I won't let out some cooler features.)

The principle of implementation:

1. Configure the auxiliary service class.

two。 Distinguish the page by traversing the node.

3. Crawling specific nodes performs operations and jumps between pages and inputs by simulating gestures.

Code implementation:

First of all, we need to register an AccessibilityService.

Profile accessible_service_config.xml:

For the meaning of the parameters, please refer to API. Note here that packageNames I wrote is the package name of Wechat. If it is not specified, it will monitor all programs. If you specify a specific package name, you will only listen on specific programs.

Then configure the auxiliary service class in MaineFast:

The way you write it is a paradigm, so be careful not to lose permissions.

Then we need to implement an auxiliary service class:

/ * Created by jiangzn on 17-2-6. * / public class MyAccessibilityService extends AccessibilityService {@ Override protected void onServiceConnected () {LogUtils.d ("onServiceConnected");} String description; @ Override public void onAccessibilityEvent (AccessibilityEvent event) {} @ Override public void onInterrupt () {LogUtils.d ("onInterrupt");}}

Implement our account switching method in the onAccessibilityEvent method:

/ * * account switching * defaults to the Wechat main interface * @ param rootNodeInfo * @ param event * / private void test2 (AccessibilityNodeInfo rootNodeInfo, AccessibilityEvent event) {/ / 3. Exit the current account button List quiteNowCounts = rootNodeInfo. FindAccessibilityNodeInfosByViewId ("com.tencent.mm:id/bch"); LogUtils.d ("number of buttons to exit the current account:" + quiteNowCounts.size ()); / / 4. The big back button identifier List bigquitetagNow = rootNodeInfo. FindAccessibilityNodeInfosByText ("No historical data will be deleted after exiting the current account, and you can still use this account the next time you log in.") ; LogUtils.d ("number of big back button identifiers:" + bigquitetagNow.size ()); / / 5. Find more buttons List moreInfo = rootNodeInfo. FindAccessibilityNodeInfosByViewId ("com.tencent.mm:id/bcb"); LogUtils.d ("more quantity:" + moreInfo.size ()); / / 6. Switch account button List changeBtnInfo = rootNodeInfo. FindAccessibilityNodeInfosByViewId ("com.tencent.mm:id/akv"); LogUtils.d ("number of buttons for switching accounts:" + changeBtnInfo.size ()); / / 7. Use the other way to log in button List changeWayInfo = rootNodeInfo. FindAccessibilityNodeInfosByText ("login by other means"); LogUtils.d ("number of login buttons by other means:" + changeWayInfo.size ()); / / 8. Go to Wechat login interface and start login List logintitleInfo = rootNodeInfo.findAccessibilityNodeInfosByText ("login Wechat"); LogUtils.d ("number of title boxes of login interface:" + logintitleInfo.size ()); if (logintitleInfo.size ()! = 0) {List loginInputInfo = rootNodeInfo.findAccessibilityNodeInfosByViewId ("com.tencent.mm:id/gr") For (AccessibilityNodeInfo tempNode: loginInputInfo) {if (tempNode.getText ()! = null&&tempNode.getText (). ToString (). Contains ("QQ account / WeChat / Email") {LogUtils.d ("enter account"); NodeUtils.NodeInfoInput (tempNode, "WeChat"); loginInputInfo.remove (tempNode); LogUtils.d ("enter password"); NodeUtils.NodeInfoInput (loginInputInfo.get (0), "Wechat password") / / Click the login button List loginbtns = rootNodeInfo.findAccessibilityNodeInfosByViewId ("com.tencent.mm:id/bbt"); loginbtns.get (0) .performAction (AccessibilityNodeInfo.ACTION_CLICK);} else if (changeWayInfo.size ()! = 0) {LogUtils.d ("Click the login button in another way"); changeWayInfo.get (0) .performAction (AccessibilityNodeInfo.ACTION_CLICK) } else if (changeBtnInfo.size ()! = 0) {LogUtils.d ("Click the switch account button"); List changgeCount = rootNodeInfo. FindAccessibilityNodeInfosByViewId ("com.tencent.mm:id/fa"); changgeCount.get (0). GetParent (). PerformAction (AccessibilityNodeInfo.ACTION_CLICK);} else if (moreInfo.size ()! = 0) {LogUtils.d ("Click more buttons"); moreInfo.get (0) .performAction (AccessibilityNodeInfo.ACTION_CLICK);} else if (bigquitetagNow.size ()! = 0) {List bigquiteNow = rootNodeInfo. FindAccessibilityNodeInfosByViewId ("com.tencent.mm:id/abg"); LogUtils.d ("number of big back buttons:" + bigquiteNow.size ()); bigquiteNow.get (0) .performAction (AccessibilityNodeInfo.ACTION_CLICK);} else if (quiteNowCounts.size ()! = 0) {LogUtils.d ("Click the mini back button"); / / Click to exit the current account quiteNowCounts.get (0) .performAction (AccessibilityNodeInfo.ACTION_CLICK) } else {/ / Recursively find the exit button / / NodeUtils.findNodeByTxt (rootNodeInfo, "quit"); if (description.contains ("chat")) {/ / 1. Recursively find the setting button List setBtns = rootNodeInfo.findAccessibilityNodeInfosByText ("setting"); LogUtils.d ("set the number of buttons:" + setBtns.size ()); / / Click the setting button setBtns.get (0). GetParent (). PerformAction (AccessibilityNodeInfo.ACTION_CLICK);} else if (description.contains ("Settings")) {/ / 2. Recursively find the exit button List quiteBtns = rootNodeInfo.findAccessibilityNodeInfosByText ("exit"); LogUtils.d ("set the number of exit buttons in the interface:" + quiteBtns.size ()); / / Click the exit button quiteBtns.get (0). GetParent (). PerformAction (AccessibilityNodeInfo.ACTION_CLICK);} else {}}

Here you can see that the whole process is divided into eight logic.

Each logical step is to traverse the node to find the specified button, and then simulate the button click.

Because onAccessibilityEvent is triggered by a loop, it will always trigger the interface logic we need, execute it all the time, and finally achieve the effect of automatically switching accounts.
