In an application, there are usually multiple Activity, and each Activity corresponds to an UI layout file. In general, in order to maintain a consistent style between different windows, many of the same layouts will almost certainly be used in these UI layout files. If we rewrite the same layout in each xml file, one is code redundancy and poor readability, and the other is troublesome to modify, which is very disadvantageous to later modification and maintenance. So, in general, we need to write the code with the same layout as a separate module, and then when we use it, we can reuse the layout code through tags.

It is common that some applications have a title bar at the top. Similar to the figure below.

Example of the title bar of the figure

If most of the Activity layouts in the project contain such a title bar, you can write the layout of the title block as a separate xml file.

We name the above xml file "navigator_bar.xml", and other Activity xml layout files that require title blocks can refer to this file directly.

Experience sharing:

In general, the style of the overall UI can be roughly determined at the beginning of the project. So in the early days, we can make some plans to write out the general modules first.

Here are some common layouts that can be pulled out:

1) background. Some applications use a unified background in different interfaces. The default background may be changed frequently later, so you can make the background into a generic module.

2) title bar of the head. If the application has a unified header title bar, it can be extracted.

3) Navigation bar at the bottom. If the application has a navigation bar, and the bottom navigation bar of most Activity is the same, you can write the navigation bar as a general module.

4) ListView. Most applications use ListView to display multiple pieces of data. The style of ListView may be adjusted frequently later in the project, so it is better to use ListView as a general-purpose module.

Thank you for your reading, the above is the content of "what is the optimization method of Android for interface UI". After the study of this article, I believe you have a deeper understanding of what the optimization method of Android for interface UI is, and the specific use needs to be verified in practice.
