Java 以编程方式使用辅助功能服务读取通知栏标题、消息
使用可访问性服务，我能够阅读通知栏标题和消息，我面临的问题是，当第一次通知出现时，我正在完美地阅读所有这些内容，但在第一次通知及以后，我只收到标题和文本“Youhave2messages”等等，而不是整条消息。 等待您的专家建议 代码：Java 以编程方式使用辅助功能服务读取通知栏标题、消息,java,android,notifications,accessibilityservice,Java,Android,Notifications,Accessibilityservice,使用可访问性服务，我能够阅读通知栏标题和消息，我面临的问题是，当第一次通知出现时，我正在完美地阅读所有这些内容，但在第一次通知及以后，我只收到标题和文本“Youhave2messages”等等，而不是整条消息。 等待您的专家建议 代码： @Override protected void onServiceConnected() { Log.d("AccessibilityServiceNotification", "ServiceConnected");

消息：您有两条消息（而不是：您在做什么）试试这个，下面的代码对我有用-
Notification notification = (Notification) event.getParcelableData();
RemoteViews views = notification.contentView;
Class secretClass = views.getClass();
try {
Map<Integer, String> text = new HashMap<Integer, String>();
Field outerFields[] = secretClass.getDeclaredFields();
for (int i = 0; i < outerFields.length; i++) {
if (!outerFields[i].getName().equals("mActions")) continue;
outerFields[i].setAccessible(true);
ArrayList<Object> actions = (ArrayList<Object>) outerFields[i]
.get(views);
for (Object action : actions) {
Field innerFields[] = action.getClass().getDeclaredFields();
Object value = null;
Integer type = null;
Integer viewId = null;
for (Field field : innerFields) {
field.setAccessible(true);
if (field.getName().equals("value")) {
value = field.get(action);
} else if (field.getName().equals("type")) {
type = field.getInt(action);
} else if (field.getName().equals("viewId")) {
viewId = field.getInt(action);
}
}
if (type == 9 || type == 10) {
text.put(viewId, value.toString());
}
}
System.out.println("title is: " + text.get(16908310));
System.out.println("info is: " + text.get(16909082));
System.out.println("text is: " + text.get(16908358));
}
} catch (Exception e) {
e.printStackTrace();
}
Notification Notification=（Notification）event.getParcelableData（）；
RemoteViews=notification.contentView；
Class secretClass=views.getClass（）；
试一试{
映射文本=新的HashMap（）；
Field outerFields[]=secretClass.getDeclaredFields（）；
for（int i=0；i<?xml version="1.0" encoding="utf-8"?>

使用通知中的
附加项额外文本行Notification notification = (Notification) event.getParcelableData();
CharSequence[] lines = notification.extras.getCharSequenceArray(Notification.EXTRA_TEXT_LINES);
int i = 0;
for(CharSequence msg : lines)
{
Log.d("Line " + i, (String) msg);
i += 1;
}
此代码对我来说非常适用：
List<String> msgs = new ArrayList<String>();
msgs.add("Info: " + notif.extras.getString(Notification.EXTRA_INFO_TEXT));
msgs.add("Title: " + notif.extras.getString(Notification.EXTRA_TITLE));
msgs.add("Text: " + notif.extras.getString(Notification.EXTRA_TEXT));
