How to customize the Android interface, in view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

If you want to go directly to your own defined Android interface, you can add a custom Action value to the recipient's IntentFilter. They are all observer patterns that use the design pattern, for reference only.

One is to write the layout Layout graphically. These layouts are saved in the XML file, compiled into resources, loaded by the Activity in the program (setContentView ()), and then manipulated by findViewById to obtain references to each interface component.

For most people, they like the most intuitive way, that is, the way it is generated dynamically in the code. Let's start from here, as for the way of visual programming and layout of resources, we will talk about it later.

First, layout management (Layout)

Each interface component is a subclass of View and can occupy a separate screen, but the really useful interface is the combination of these components. All kinds of Layout are used for layout management in the Android interface, which is basically the same as some AWT,SWING interfaces in the traditional J2SE.

Second, a single interface element:

Public class HelloActivity extends Activity {/ * * Called when the activity is first created. * / @ Override public void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); TextView tv = new TextView (this); tv.setText ("Hello, World!"); this.setContentView (tv);}} Layout is not used here, this is the separate component approach. You can also change it to: super.onCreate (savedInstanceState); Button btn = new Button (this); btn.setText ("TestButton"); this.setContentView (btn); compile and run, there will be a full-screen Button, of course, this is not the practical interface you want. Then we use Layout to layout super.onCreate (savedInstanceState); Button btn = new Button (this); btn.setText ("TestButton"); Button btn2 = new Button (this); btn2.setText ("TestButton2"); LinearLayout layout = new LinearLayout (this); layout.setOrientation (LinearLayout.VERTICAL); layout.addView (btn); layout.addView (btn2) This.setContentView (layout)

Compile and run, you can see two buttons arranged up and down. Of course, anyone who has done AWT,SWING on PC is no stranger to the use of the layout manager, so I won't repeat it here. So how to respond to the event: guess? It must be easy for you to guess.

In AWT, in the J2ME of mobile phones, Listener is used to deal with event responses, and the Android interface is not vulgar. This is the same as Observer in Blackberry,Symbian. It is the observer pattern that uses the design pattern. Let's take a look at an example that can respond to events.

The steps are:

First, generate two Button, configure the Click event listener to HelloActivity, and this class implements the OnClickListener interface.

Second, put in the layout and display two Button according to the layout

Third, press one of the Button, generate the Click event, and call the OnClick interface function of HelloActivity.

Fourth, for the value of the View parameter, determine which View (Button) it is. Rewrite the Titile content of Activity. Note that do not compare View.getId (), by default, the ID value of each component is-1, unless the ID value is artificially set, and an ID value is automatically generated for it when visually programmed.

This is the answer to the question about how to customize the Android interface. I hope the above content can be of some help to you. If you still have a lot of doubts to solve, you can follow the industry information channel to learn more about it.
