What's the difference between a goal and a task?

What's the difference between a goal and a task? Goals are concrete and quantifiable, and they are born from the purpose. A plan is a plan to achieve a goal, and a task is that each completion point in the plan generally has a purpose first, then a plan, and then a goal, and the goal is achieved through a task.

If a person wants to make his life meaningful, he must set up lofty ideals. Of course, if you haven't figured out how to implement it, you will think that your goal is very big and may be difficult to accomplish. You can break down a big goal into several small goals, and then complete the small goals one by one. This method can help you overcome your fears and follow the plan.

When you accomplish small goals, you should be confident, you can't give up halfway, you should persist in doing it, and you should do a small thing again and again. You should adjust your mentality, you should constantly encourage yourself and believe that you can do a small thing well. As long as you want to do something seriously, you firmly believe that you will do it well.

After you have the experience of completing one thing, sum up the experience in time, further enhance your self-confidence, move towards another goal, and try your best to complete it successfully.

You will feel very happy when you finish the task. You are a confident and most successful person! You are still young, believe in your ability, and you must be the winner!

The goal is initiative and the task is passive. The goal is a hard indicator of a task, but it can be divided into long-term and short-term. The task is what you need to complete at present. They also have sex. You set your own goals. The task may be set by yourself, or it may be assigned to you by others.

What's the difference between "task" and "goal"? Tasks are generally passive, and others have to give you some tasks.

The goal is generally active. Set goals for yourself.

1, the goal is concrete and quantifiable, and comes from the purpose.

2. The task is every completion point in the plan.

3. Generally, there is a purpose first, then a plan, and the task is used to accomplish the goal.

Goals are concrete and quantifiable, and they are born from the purpose. A plan is a plan to achieve a goal, and a task is that each completion point in the plan generally has a purpose first, then a plan, and then a goal, and the goal is achieved through a task.

What's the difference between main task and sideline task? Personally, I feel that the main line gives things experience, and most of the SP lines are money and things.

What's the difference between a program and a task? A program records all programs executed by your computer, including tasks, viruses, system programs and so on. Any termination of the program will have an impact on the computer. Ctrl+alt+del can view

The task is the application (such as IE, QQ, games = =) that you open after executing the computer.

Ending a task usually does not affect the computer system.

What's the difference between a night show ds with a task and one without a task? Attention: Please look at me. There are many good performance places in Shanghai, where I can perform at night. However, there are many swindlers, especially those nightclubs that are established by intermediaries in official website. Nightclubs don't set up their own websites. I'll probably tell you the situation so as not to be cheated. I am the leader of the model association and look forward to all the beautiful women.

First, don't bring a lot of cash when you go to the interview, whether it's true or not.

Second, the night recruitment in Shanghai is all recruited by the team leader himself or introduced by friends around him.

Thirdly, if you interview what high-end office building and personnel department he took you to, don't consider turning around and leaving, because no nightclub in Shanghai will set up a personnel department because of such a trivial matter as recruiting people.

First, promise not to charge any deposit and fees, and the company's customers are stable.

Second, announce that this advertisement is the only advertisement on the Internet that really recruits women.

3. In order to confirm the authenticity of this recruitment, we can look at the advertisements of online recruitment and see if there is anything like us that promises not to charge any deposit and fees.

No matter how good things are, it is better to see them with your own eyes. In order to prevent being cheated, please come directly to the venue for an interview at night. You don't need to bring a penny. Those who meet the requirements will show you the working environment and other similar staff first, and then consider whether to work here by yourself. This is entirely voluntary and never involves any illegal work.

If you are not satisfied with your present job, if you want to earn more money, if you are full of longing for the future, and if you like nightlife, here will give you another choice and a chance to grasp the future.

Non-intermediary, I promise no charge, please remember "where important people don't need money, where they need money, there is no shortage of people"

What's the difference between android handler and asynchronous tasks? In fact, handler is not comparable to asynchronous tasks, and your foundation needs to be strengthened. The following csdn blog has a detailed introduction of handler.

The principle, advantages and disadvantages of AsyncTask implementation.

The lightweight asynchronous class AsyncTask provided by android can directly inherit AsyncTask, realize asynchronous operation in the class, provide an interface to feed back the current asynchronous execution degree (UI progress update can be realized through the interface), and finally feed back the execution result to the UI main thread.

Use advantages:

Simple and quick

Process controllable

Disadvantages of use:

This becomes complicated when multiple asynchronous operations are used and the Ui needs to be changed.

The principle, advantages and disadvantages of asynchronous implementation of handler

When implementing handlers asynchronously, there are four objects involved: handlers, loop programs, messages and threads. The process of realizing asynchronism is that the main thread starts the thread (child thread) to execute, generates messages -Looper gets messages and passes them to Handler to get messages one by one in Looper and make UI changes.

Use advantages:

Clear structure and clear functional definition

For multiple background tasks, it is simple and clear.

Disadvantages of use:

When a single background is processed asynchronously, it appears that there are too many codes and the structure is too complex (relativity).

Introduction to asynchronous tasks

Android's AsyncTask is lighter than Handler (only the code is lighter, but it actually consumes more resources than handler), which is suitable for simple asynchronous processing.

Firstly, it is clear that Android has Handler and AsyncTask in order not to block the main thread (UI thread), and UI update can only be completed in the main thread, so asynchronous processing is inevitable.

In order to reduce the difficulty of development, Android provides AsyncTask. AsyncTask is a packaged background task class, which is an asynchronous task as its name implies.

AsyncTask directly inherits from the Object class and is located at android.os.AsyncTask To use AsyncTask, we need to provide three generic parameters and overload several methods (at least one).

AsyncTask defines three general types Params, Progress and Result.

Params starts the input parameters of the task execution, such as the URL of the HTTP request.

The percentage of progress background tasks that have been executed.

Result the final result returned by the background execution task, such as String.

Students who have used AsyncTask know that loading data asynchronously must rewrite at least the following two methods:

DoInBackground(Params…) is executed in the background, and time-consuming operations can be put here. Note that the UI cannot be operated directly here. This method is executed in the background thread and usually takes a long time to complete the main work of the task. During the execution, you can call publicProgress(Progress…) to update the progress of the task.

OnPostExecute(Result) is equivalent to the way that Handler handles UI, in which the result obtained in doInBackground can be used to handle operation UI. This method is executed in the main thread, and the result of task execution is returned as the parameter of this method.

If necessary, you must rewrite the following three methods, but this is not necessary:

OnProgressUpdate(Progress…) can use the progress bar to increase the user experience. This method is executed in the main thread and used to display the progress of task execution.

OnPreExecute () This is the interface when the end user calls Excute. This method is called before the task is executed and the progress dialog box can be displayed here.

OnCancelled () What does it do when the user calls cancel?

When using the AsyncTask class, here are some guidelines that must be followed:

You must create an instance of the task in the UI thread;

The execute method must be called in the UI thread;

Do not manually call onpreexecute (), onpostexecute (result), doinbackground (params ...), onprogressupdate (progress ...);

This task can only be executed once, otherwise an exception will appear if it is called many times;

Introduction of handler

1.Handler mainly accepts the data sent by the child thread, and uses these data to update the UI with the main thread.

When the application starts, Android will open a main thread first. The main thread is a UI control component in the management interface, which distributes events. Updating UI can only be done in the main thread, and it is dangerous to operate in the sub-thread. Handler is needed to solve this complicated problem at this time. Since the handler runs in the main thread (UI thread), it can transmit data to the child thread through the message object. At this point, the handler is responsible for accepting the message objects (including data) sent by the child thread (passed by the child thread with the sedMessage () method) and putting these messages in the queue of the main thread to update the UI with the main thread.

Second, the characteristics of handlers

Handler can distribute message objects and Runnable objects to the main thread, and each Handler instance will be bound to the thread that created it.

It has two functions:

(1) Arranges the message or Runnable to run somewhere in the main thread.

(2) Arrange an action to be executed in different threads.

Some methods of distributing messages in handlers

Release (runnable)

postAtTime(Runnable，long)

Post-delay (can run for a long time)

senemptymessage(int)

Send a message (message)

SendMessageAtTime (long message)

SendMessageDelayed (long message)

The post class method above allows you to arrange a Runnable object in the main thread queue.

The sendMessage class method allows you to arrange a message object with data in the queue for update.
