Complete example of Android application welcome interface based on viewpager

This article describes the application welcome interface of Android based on viewpager. Share with you for your reference, as follows:

Sometimes when developing an application, you need to guide the user to prompt some new functions. The implementation of such a welcome interface can use the following methods

First of all, we need to use the viewpager class. This class is in android-support-v4.jar. You can search it on the Internet

Now put this package into the project and reference it later

The personal understanding of the viewpager class is that it is a container that fills the image resources you need into its adapter, so we need an adapter, customize an adapter, inherit the pageradapter, and then set the setadapter () of the viewpager

Next, sort out the implementation idea of small dots, prepare two pictures, one is the selected state and the other is the unselected state, and then use the selector to set its changes

This is the idea of the whole project. Please refer to the following code for details:

Layout file

Set the selector for small dots
