layout, the system will generate the code setContentView (R. Layout. main) by default. Is this the case when Preference is used? I believe that Preference can be used as a layout file, but when I load it into the simulator (setContentView (R. xml. preference), the following error is returned: Caused by: android. view. inflateException: Binary XML file line #2: Error inflating class PreferenceScreen Caused by: java. lang. classNotFoundException: andro

the purpose of extending and enhancing the function of software, in this regard Jess is no exception. In this paper, from the Jess language to provide user-defined function interface Userfunction [3-4], to analyze the implementation of Useffunction interface specific details, This paper analyzes the intrinsic relation

This article mainly introduces the PHP version of the data statistics interface usage, combined with the example form analysis of PHP data statistics interface functions and related use skills, the need for friends can refer to the following PHP version of the data statistics interface is actually very useful in the p

behaviors, butIt is this group of behaviors that can be implemented in any specific way possible. This abstract description is an abstract class, and this set of arbitrary possible concrete implementationsis represented by all possible derived classes. Like, an animal is an abstract class, Human, Monkey, Tiger is a concrete implementation of derived classes, we canUse animal types to hide the types of people, monkeys, and tigers.(ii) analysis from a grammatical definitionAt the syntactic level,

usingInterface mode definition. Obviously, because the Java language does not support multiple inheritance, both concepts are defined using abstract class. The latter two methods are feasible, but their selection reflects the understanding of the concept nature in the problem field, and whether the reflection of the design intent is correct and reasonable. Let's analyze and explain them one by one. If both concepts are defined using the

field, and whether the reflection of the design intent is correct and reasonable. Let's analyze and explain them one by one. If both concepts are defined using the interface method, there are two problems: 1. We may not understand the problem field clearly. The concept of alarmdoor is essentially true. Is it door or an alarm? 2. If we have no problem understanding about the problem field, for example, thro

First, prefaceFrom an application perspective, there are three types of time-related services that the kernel needs to provide:1, and system time-related services. For example, when you write a record to a database, you need to record the operation time (when and where the month is).2. Let the process sleep for some time3, and timer-related services. After a specified period of time has elapsed, kernel to alert the user processThis paper mainly descri

Subversion is a file versioning tool that is widely used as the source code version management.Existing tools, whether their own command-line tools or Windows UI TortoiseSVN, are also very handy, but if you want to integrate with the existing system, in addition to its built-in hook script function, it is necessary to use the SVN API, this API is written in C , so it is inconvenient for other languages such as Jav
