学习功能强大的AccessibilityService！！！
以下是本人根据自动抢红包的实现思路敲的用于微信自动向附近的人打招呼的核心代码
public class AutoService extends AccessibilityService implements View.OnClickListener { private static final String TAG = "test"; /** * 微信的包名 */ static final String WECHAT_PACKAGENAME = "com.tencent.mm"; /** * 推送消息在通知栏的关键字，设置为推送账号名,如【十点读书】 */ static final String PUSH_TEXT_KEY = "十点读书"; /** * 推送链接的关键字，所有推送链接的标题都需要包含此关键字：如【深度好文】 */ private static final String URL_TEXT_KEY = "深度好文"; /** * 向附近的人自动打招呼的内容 */ private String hello = "测试APP自动打招呼功能，这是一条测试信息"; boolean startFunc2 = false;//标记是否开启自动添加附近的人为好友的功能; int i = 0;//记录已打招呼的人数 int page=1;//记录附近的人列表页码,初始页码为1 int prepos = -1;//记录页面跳转来源，0--从附近的人页面跳转到详细资料页，1--从打招呼页面跳转到详细资料页 @Override public void onAccessibilityEvent(final AccessibilityEvent event) { int eventType = event.getEventType(); //通知栏事件 //自动打开推送的链接 if (eventType == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) { List<CharSequence> texts = event.getText(); if (!texts.isEmpty()) { for (CharSequence t : texts) { String text = String.valueOf(t); if (text.contains(PUSH_TEXT_KEY)) { openNotification(event); openDelay(1000, URL_TEXT_KEY); } } } } //自动加人 if (!startFunc2) { return; } if (eventType == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && event.getClassName().equals("com.tencent.mm.ui.LauncherUI")) { //记录打招呼人数置零 i = 0; //当前在微信聊天页就点开发现 openNext("发现"); //然后跳转到附近的人 openDelay(1000, "附近的人"); } else if (event.getClassName().equals("com.tencent.mm.plugin.nearby.ui.NearbyFriendsUI") && eventType == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) { prepos = 0; //当前在附近的人界面就点选人打招呼 AccessibilityNodeInfo nodeInfo = getRootInActiveWindow(); List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByText("米以内"); Log.d("name", "附近的人列表人数: " + list.size());

} AccessibilityNodeInfo nodeInfo_ = getRootInActiveWindow(); List<AccessibilityNodeInfo> list_ = nodeInfo_.findAccessibilityNodeInfosByText("米以内"); Log.d("name", "列表人数: "+list_.size()); //滑动之后，上一页的最后一个item为当前的第一个item，所以从第二个开始打招呼 list_.get(1).performAction(AccessibilityNodeInfo.ACTION_CLICK); list_.get(1).getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK); } }).start(); } } } } else if (event.getClassName().equals("com.tencent.mm.plugin.profile.ui.ContactInfoUI") && eventType == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) { if (prepos == 1) { //从打招呼界面跳转来的，则点击返回到附近的人页面 performGlobalAction(AccessibilityService.GLOBAL_ACTION_BACK); i++; } else if (prepos == 0) { //从附近的人跳转来的，则点击打招呼按钮 AccessibilityNodeInfo nodeInfo = getRootInActiveWindow(); if (nodeInfo == null) { Log.w(TAG, "rootWindow为空"); return; } List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByText("打招呼");

启用这个服务的代码：
//打开系统设置中辅助功能 Intent intent = new Intent(android.provider.Settings.ACTION_ACCESSIBILITY_SETTINGS); startActivity(intent);
