Android dynamically adds indicator navigation to viewpager

Let's see the effect first

The shape and color of small dots can be defined by themselves, depending on the demand

First, slide two dots, one is the selected dot and the other is the unselected dot. Look at the selected dot shape

Unselected

Is it simple to specify a circle and a color

The next step is to define a selector to control selected and unselected

Then there is the layout file of mainactivity. Place a viewpager and a LinearLayout below to hold small dots

Next is the code of mainactivity. In fact, it is very simple and has comments. I won't go into detail

Finally, attach the adapter of viewpager
