nativescript vue back button handler
// Step 1: Import the required modules
import { onBeforeUnmount } from 'vue';
import { Application, AndroidApplication, AndroidActivityBackPressedEventData } from '@nativescript/core';
// Step 2: Define a function to handle the back button press
function handleBackButton() {
// Your custom logic for handling the back button press goes here
// For example, navigating back or showing a confirmation dialog
}
// Step 3: Register the back button handler when the component is created
const onMounted = () => {
// For Android
if (Application.android) {
Application.android.on(AndroidApplication.activityBackPressedEvent, handleBackButton);
}
};
// Step 4: Unregister the back button handler when the component is destroyed
const onUnmounted = onBeforeUnmount(() => {
// For Android
if (Application.android) {
Application.android.off(AndroidApplication.activityBackPressedEvent, handleBackButton);
}
});
// Step 5: Export the lifecycle hooks
export { onMounted, onUnmounted };
Note: Make sure to adapt the handleBackButton
function according to your specific requirements. This example focuses on setting up the back button handler in a Vue component using NativeScript-Vue for Android.
