I. I took part in school recruitment in March and concentrated on those three or four days to test the effect of my fast self-study front-end during the summer vacation.
II. The record is as follows:
A online test, one side, two sides, no message
Netease did not go online for a written test due to geographical reasons
T, written examination
B's written test, one side, two sides, no news
Meituan, written test
VIP, written test

An Android app can contain multiple activity, and an activity can initiate another activity.The activity is managed with a stack structure, and the newly opened activity is stacked on top of the current activity, and the current activity stops running.When an activity stops running, the Android system retains its pre-stop state, and when the user presses the "Back" button, the top activity of the stack is rolled out of the stack and the previous activity moves to the top of the stack and is disp
described in detail later. This example changes the value of haunted preference once every 1 seconds (selected, not selected, not selected).Registeronsharedpreferencechangelistener,unregisteronsharedpreferencechangelistener used for Sharedpreferences Registers a total preference Change event handling code. In this example, the number of times the current button is displayed on the screen when the mypreference changes:"Sail Plan 031" 2015 sail
the service is re-created when Onstartcommand is called, the last intent is not passed in as a parameter, that is, intent=null. Start_redeliver_intent will pass in the last intent that was not processed before being killed.This service is not used as a bind service, so it is implemented by an empty implementation:@Override Public ibinder onbind (Intent Intent) { returnnull;}Finally, to see how to start/stop this service, controller is implemented as the control class for this service, provide

The Reorder activities example has four related activitives:reorderonlaunch, Reordertwo,reorderthree, Reorderfour. Where Reorderonlaunch is the main activity,reorderonlaunch start Reordertwo, Reordertwo starts reorderthree,reorderthree. At this time, the "Back stack" of the activity has the following status:Reorderfour want to start reordertwo again, at this time with two implementation methods, one is to start a new reordertwo above the Recordfour, which is the default behavior of StartActivity
The Local service Controller uses LocalService as a "Started" service, which is much simpler than the "Bound" service, Localserviceactivities.controller started the local Service, it basically doesn't matter localservice.StartService (new Intent (Controller. this, LocalService. class));LocalService can choose to stop itself, this example is by calling StopService to stop the service, if you start the service in this example, there is no stopservice, the service will run in the background, Even

If the project manager cannot solve the resource allocation problem, the project progress plan will not succeed.
When most of the activities in a project are similar to other activities that have previously been executed, the Key Path Method (CPM) is usually used for planning. The estimation of the CPM activity duration is usually based on the duration data and uses the average value of the previous project activity duration.

boyfriend? Can't I find it? After reading this article, we can see that no one dares to ask for it, no company wants it, and you can't imagine it. Besides, I have to wait for another three years at huagong, which is actually a place to go to bed. Big companies should all focus on graduate students. Look, this is the spiritual victory of Self-comfort. If you have any ideas about the advantages and disadvantages of reading and researching by girls, please let me know that I cannot afford the mora

I just spent two hours writing an article. After I click the "post" button, all the text content will be cleared. Is it because it has been lost? But I really didn't have a Green Dam. Well, at least this has aroused the impulse to write again. It seems that csdn is actually engaged in technology and can only be released in Sina.
The preliminary plan for the summer vacation is as follows to ensure that all are done.
