Android custom viewpager indicator

This example shares the production method of Android viewpager indicator for your reference. The specific contents are as follows

1. General

The viewpageindicator, an open source framework, has been contacted by everyone. I feel it's good, but it's troublesome to use. It needs to be configured here and there, and it's inconvenient to customize the configuration effect. The first time I used it, I couldn't get the effect. After looking for it for a long time, I found that the theme of activity was not configured properly. Today, we will build a wheel and implement it ourselves. The adapter mode is used. If you don't know this mode, please see my android source code design pattern analysis: https://www.oudahe.com/p/27593/ , let's see the effect:

2. Realization

1) . to achieve the basic effect, customize horizontalscrollview extensions, set viewpager to continuously traverse and add sub views according to the number.

2）. Set the scrolling listening of viewpager to make viewpager and tabview linked together

3）. Finally, we use the adapter mode to complete the highlighting and subscript indicators.

4）. Finally, let's look at how to use it in the activity. There are four methods in the indicatoradapter. We only need to implement one method. If the other three methods are not used, they can not be replicated. If it is exposed in the form of an adapter, users can implement it without being limited.
