Listen to the back press event

This topic guides you through how to listen for the mini program back press event.

Overview

From IAPConnect 2.34.0, Griver supports the back press event by implementing the GriverBackPressedPointEvent interface. The following sections provide the detailed steps:

Step 1. Implement GriverBackPressedPointEvent

To listen for the mini program back button press event, implement the GriverBackPressedPointEvent interface, and write your business logic in the handleBackPressed function:

public class DemoGriverBackPressedPointEvent implements GriverBackPressedPointEvent {

  @Override
  public void handleBackPressed(Page var1) {}

  @Override
  public void onInitialized() {}

  @Override
  public void onFinalized() {}
}

Step 2. Register the back press event

Register the back press event during initializing:

Griver.registerEventHandler(
  new GriverEventManifest(
    DemoGriverBackPressedPointEvent.class.getName(),
    Arrays.asList(GriverBackPressedPointEvent.class.getName()),
    App.class
  )
);
