Example of association between Android viewpager and radiogroup implementation

Android viewpager is associated with radiogroup

Rendering display

Android viewpager and radiogroup implementation Association steps

1. Instantiate viewpager

2. Load the layout through layoutinflator and return the view result

3. Add each generated view object to the list collection

4. Instantiate the adapter and pass the view set

5. The adapter relay is inherited from pageradapter and implements four internal methods

6. Instantiate each RadioButton

7. When clicking each raidobutton, switch to a different page (viewpager. Setcurrentltem (subscript))

8. After page switching, turn the current navigation bar to green

9. When you click before each time, add a method, clear method, (the status of all navigation bars before cleaning is grayed out)

10. Addonpagerchangelistener is required to realize sliding monitoring

11. In the onpagerselected method, set the corresponding bottom navigation bar status according to the subscript judgment of the position page

Code demonstration

1. Introduce android-support-v4.jar package in the main layout file, add radiogroup, and add RadioButton in radiogroup to display the navigation bar

2. Viewpager needs the adapter to inherit from pageradapter

3. Create a new fragment package. Create a onefragment class in the package for sliding display. Create a new layout file fragmentone.xml and add textview to add the contents of different pages. There are four in total, and only one is written here

Onefragment class

fragmentone.xml

4. Prepare main category
