Simple implementation of Android boot page

When you enter the application for the first time, there will be a guidance page. The implementation of the guidance page is also very simple, and there are many ways to implement it. The following is the effect of a guidance page written by yourself. The general implementation ideas are as follows:

The outermost layer is a fragmentactivity, which contains four fragments. In the fragment, a cycle is opened for viewpager to realize picture broadcasting. In fact, the effect is that several fragments in the fragmentactivity slide switch, and viewpager in the fragment rotates and slides indefinitely;

The following is the code implementation:

Here, it should be noted that when the viewpager and fragment slide change, the selected color of the small circle at the bottom will be changed;

The above is the main code for effect realization, and the effect operation is as follows:

A small part of the effects in the above effect drawing are not shown. In fact, the circle above is cyclic and can slide at the same time;
