监听通知栏获取支付宝到账信息
[toc]
定义service
@SuppressLint("OverrideAbstract")
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR2)
public class PayReceiver extends NotificationListenerService {
private static final String TAG = "lht";
@Override
public void onCreate() {
super.onCreate();
}
@RequiresApi(api = Build.VERSION_CODES.KITKAT)
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
// Toast.makeText(this,"收到消息",Toast.LENGTH_SHORT).show();
Notification notification = sbn.getNotification();
if (notification == null) {
return;
}
Bundle extras = notification.extras;
if (extras != null) {
//包名
String pkg = sbn.getPackageName();
// 获取通知标题
String title = extras.getString(Notification.EXTRA_TITLE, "");
// 获取通知内容
String content = extras.getString(Notification.EXTRA_TEXT, "");
Log.i(TAG, String.format("收到通知，包名：%s，标题：%s，内容：%s", pkg, title, content));
//处理
processOnReceive(pkg, title, content);
}
}
}
权限获取
