Using viewpager to implement Android Software wizard function implementation steps

The layout file is as follows:

In addition, we need four layout files, which are the images to be displayed by the wizard. Each layout file is a page, and each layout file contains an ImageView. As follows:

Layout file I:

Layout document II:

Layout document III:

Layout file IV:

Then load the four layout files and the main layout file in the code:

Activity Code:

First, load 4 layouts and main layout files to be displayed from layoutinflator.

Then put the layout file as a view into an ArrayList.

Then find viewpager and LinearLayout from the main layout. Viewpager is used to load four layout files and LinearLayout is used to load four prompt icons.

Then create four new imageviews, set the corresponding background, and add them to the LinearLayout as views.

Then set the adapter for the viewpager and the onpagechangelistener.

Getcount should be set in the adapter, which is the number of pages. Here are 4, so set 4;

At the same time, the corresponding page add in the instantiateitem and return to the corresponding page.

Remove the page when destroying the item.

In the method of selecting a page, set the background of the selected icon in onpageselected.
