Research Of A Interactive Programming Learning System

With the rapid development of the mobile internet,a great number of programmers are needed.But the novice may hardly understand the program codes and the mechanism of system because the programming leaning is dull and abstract.So the need for programming learning system is becoming more and more urgent.The existing programming learning systems still have such disadvantages as:they usually has only one learning model and their running processes are not based on the actual programmer's data.Obviously these systems cannot meet the needs of learners.The paper proposes a interactive programming learning system,which is based on Android system.The system can capture the actual dynamic data in running programme and display of them.Further,through the setting of the data,processes and results of the programer can be changed quickly without changing program itself.The paper studies the process of layouting of view and running of animation in Android system,discusses two methods of getting data in such process,presents a scheme for dynamic display of layouting process and compares several ideas of displaying the ViewTree's structures.On these basis,three major modules of the system are detailed designed and realized.These modules are layouting process display,interactive learning of layouting parameters and interactive learning of animation.Through the using of the system,learners can study complex processes of view's layouting and animation's making up in Android system,deepen their understanding of system's mechanism.It also can be used to show the functions of parameters in views and animations by interactive learning in system,greatly improve the learning efficiency of learners.
