BrieflyThe project through the analysis of the design patterns in the Android system to enhance people's understanding of the design pattern, from the source of the analysis of the understanding of the Android system itself, but also from the excellent design of the actual use of the model and its application of the scene, to avoid in the actual development of the mechanically. If you are not familiar with

. Differences from the policy modelThe state pattern is almost identical to the structure of the strategy pattern, like a twin brother. But they are different in their eyes and in nature. The behavior of the state mode is parallel and irreplaceable, and the behavior of the policy mode is independent and interchangeable with each other. State mode, usually a chang

stack can come from different apps, so it can be run in a different process, but they all belong to the same task.The Android system is a real-time multi-task system that allows users to switch between multiple tasks at will. When all activity in a task stack pops, the task is destroyed. Sometimes the system destroys the activity in order to reclaim memory, but the task is not destroyed.Activity has the Launchmode option in manifest and can configure

void OnClick (View v) {Intent Intent = new Intent (secondactivity.this, Thirdactivity.class);StartActivity (Intent);}});}It also prints the ID of the current return stack in the OnCreate () method, and then modifies the code of the button click event to start the thirdactivity. Finally, modify the code for the OnCreate () method in thirdactivity:@Override protected void OnCreate (Bundle savedinstancestate) {Super.oncreate (savedinstancestate);LOG.D ("Thirdactivity", "Task ID is" + gettaskid ())

" + gettaskid ()); Modifies the code of the OnCreate () method in secondactivity, printing the ID of the current return stack. log.d ("secondactivity", "Task ID is" + gettaskid ()); The last modification of the OnCreate () method in thirdactivity still prints the ID of the current return stack in the OnCreate () method. log.d ("thirdactivity", "Task ID is" + gettaskid ());Printing results:As you can see, the secondactivity Task ID differs from firstactivity and thirda

INTRODUCTION of SOCKET COMMUNICATIONThere are two main ways of communication between Android and Server, one is HTTP communication, the other is socket communication. The biggest difference between the two is that the HTTP connection uses "request-response

This article gives you an introduction to the lifecycle of activity, and if you've learned about iOS partners, the activity lifecycleis very similar to the lifecycle of Viewcontroller in iOS. Life cycle is not difficult to understand. A person's life cycle is a sickness and death, the flower life cycle is the flower bloom thanks. The life cycle of activity in Android is the process of creating and disappearing activity. This blog will introduce the di

In non-full screen mode, set the activity's windowSoftInputMode attribute to adjustResize. At the same time, you can get the changed size in onSizeChanged (int w, int h, int oldw, int oldh) of the View, and then calculate the distance to move the screen based on the results of the changes. However, in full screen mode, even if the activity's windowSoftInputMode attribute is set to adjustResize. When display

activity set to singletask mode does not always create a new taskid.When it is not the startup surface of the app, it will be the same as the startup surface taskid.However, you must pay attention to data loss when setting the non-start plane to this mode.Because it is very likely that a is a welcome page. After initialization and other time-consuming work is completed, call B and A (finish method)At this time, when the system recycles the memory and
