Nested listview in scrollview in Android

. The problem is: there is only one permission, and both views must be supported for scrolling. This is a bit difficult to implement .. In fact, this is not difficult. When the finger reaches the listview, The scrollview outside is handed over the permission. When the finger is released, the scrollview outside is re-authorized. So OK. See the code implementation: Override an innerlistview extends listview Innerlistview. Java @ Override Public Boolean Onintercepttouchevent (motion

Log API provided by JDK --- logging (first recognized)

various targets, including memory, output stream, console, file, or socket. Handler has multiple sub-classes for different output targets. You can simply call setlevel (level. Off) to disable a processor or re-open it to give a proper level. Developers can also compile Other Processors as needed, such as jmshandler or jdbchandler. Handler is an abstract class. JDK has several built-in implementation classes. Logrecord: the log record object. It can be used to transmit detailed request records b

Catel help manual-catel. Core (6): Log Management

1. Introduction Since version 2.2, catel has used a custom log system. In this way, the reference to log4net can be removed. This modification is mainly made to avoid forcing users to use log4net. At the same time, log4net does not seem to be updated for a long time. Other log systems, such as nlog, seem to be growing. The new log system will allow many basic logs. In this way, logs will be very simple, and if needed, the real log will be executed by the user.1.1 log and ilog All logs are proces

Python Log Module (article 1st)

[Reprint] the original address http://blog.sina.com.cn/s/blog_681315fa0100imtk.html If you use python to write a relatively large program, you will certainly use the log system. Especially for dynamic languages like python, many errors can only be found during running. A good log system is very important to Python programs. The simplest solution is to directly use print to output the running information. However, this is too simple and there is no grading function. If you want to remove the ru
