Simple method of realizing dialer function by Android programming

This paper describes the method of Android programming to simply realize the function of dialer. Share with you for your reference, as follows:

I've been learning Android for two days. When I didn't learn it, I thought Android might be boring, but after learning it, I found that it's much more fun than Java Web. You can see some interesting things when learning Android. Here, it is also recommended that people learning javame not suffer any more. Learn Android. You also need to know how Android works before writing programs

1. Get the component list 2. Register or register the component 3. Encapsulate the component into intention 4. Give the intention to the intention processor for processing 5. Display the interface to the user

Looking at the development process of online Android, many people say that the interface and activity can be developed in parallel, because Android also follows the MVC design mode, that is to say, Android can also have its own business layer Dao. Due to the short development history of Android, the current division of labor is not very clear. For the interface and background, you can choose one of them as your own development direction. For any piece of Android, the salary is relatively high. No more nonsense. Let's realize the function step by step.

1. Write a "text" configuration file. The default configuration file is strings.xml. You can also rewrite a configuration file here. To keep the format consistent, write the configuration file (mystring. XML)

2. Write control

In order to make you see more clearly, I will also give you the content of R document

3. Write activity

The above is the writing method of the inner class. You can also use the following writing method

During development, you should pay attention to the number of uri.parse and Tel: that is, there will be errors

To implement this function here, first take a look at XML

Here, we only need to look at the first filter. Here, we only need to use two filters. We don't need to manage the default one. In addition, we also need to obtain the call license, so we need to add something to the component list, as shown below

The preparation work is almost done. Let's test it. Here, for the convenience of testing, I got two virtual phones

Got through

This is more fun. As for the application icon, I can change it to what I like. I won't change it

Now I'll give you the strings. XML configuration file

OK, the program is written.
