Why the Spinner Disappears

Oct 13, 2025 by miodeya.com 13 views

Introduction

When working with maps, it's essential to provide a seamless user experience, especially when dealing with poor network connections. One common issue is the disappearance of the loading spinner while the map is still loading, leaving the user uncertain about the app's status. In this article, we'll explore how to maintain the spinner while the map is not fully displayed, ensuring a more intuitive and user-friendly experience.

Understanding the Problem

When a user opens a map, the app typically displays a loading spinner to indicate that the data is being fetched. However, on a poor 4G network, the spinner might disappear before the map is fully loaded, leaving the user with a blank screen. This can be frustrating, especially if the user is expecting to see the map immediately.

Why the Spinner Disappears

There are several reasons why the spinner might disappear before the map is fully loaded:

Network Connection: As mentioned earlier, a poor network connection can cause the spinner to disappear before the map is fully loaded.
Map Loading Time: If the map loading time is longer than expected, the spinner might disappear before the map is fully loaded.
App Configuration: The app's configuration might be set to hide the spinner once the map is loaded, even if the map is not fully displayed.

Solutions to Maintain the Spinner

To maintain the spinner while the map is not fully displayed, you can implement the following solutions:

1. Use a Timer

You can use a timer to keep the spinner visible for a certain period, even if the map is not fully loaded. This can be achieved by setting a timer to display the spinner for a specific duration, say 10 seconds, after the map is loaded.

// Set a timer to display the spinner for 10 seconds
setTimeout(() => {
  // Hide the spinner after 10 seconds
  spinner.setVisibility(View.GONE);
}, 10000);

2. Use a Progress Bar

Instead of using a spinner, you can use a progress bar to indicate the loading progress. This can be achieved by displaying a progress bar with a specific value, say 50%, until the map is fully loaded.

// Set the progress bar value to 50%
progressBar.setProgress(50);

// Update the progress bar value as the map is loaded
progressBar.setProgress(100);

3. Use a Custom View

You can create a custom view to display the spinner and the map simultaneously. This can be achieved by creating a custom layout with a spinner and a map view, and then updating the map view as the map is loaded.

<!-- Custom layout with a spinner and a map view -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!-- Spinner view -->
    <ProgressBar
        android:id="@+id/spinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="visible" />

    <!-- Map view -->
    <MapView
        android:id="@+id/map_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

4. Use a Library

There are several libraries available that can help you maintain the spinner while the map is not fully displayed. Some popular libraries include:

Android Maps Extensions: This library provides a set of extensions for the Google Maps Android API, including a spinner that can be used to indicate the loading progress.
Mapbox: This library provides a set of tools for building custom maps, including a spinner that can be used to indicate the loading progress.

Conclusion

Maintaining the spinner while the map is not fully displayed is essential to provide a seamless user experience, especially when dealing with poor network connections. By implementing the solutions outlined in this article, you can ensure that the spinner remains visible until the map is fully loaded, providing a more intuitive and user-friendly experience for your users.

Best Practices

When implementing the solutions outlined in this article, keep the following best practices in mind:

Use a consistent design: Ensure that the spinner and the map view are designed consistently to provide a seamless user experience.
Test thoroughly: Test the app thoroughly to ensure that the spinner remains visible until the map is fully loaded.
Optimize performance: Optimize the app's performance to ensure that the map is loaded quickly and efficiently.

Common Issues

When implementing the solutions outlined in this article, you may encounter the following common issues:

Spinner not visible: Ensure that the spinner is visible and not hidden by the map view.
Map not loaded: Ensure that the map is loaded correctly and not stuck in a loading state.
App crashes: Ensure that the app does not crash when the spinner is displayed.

Future Development

In future development, consider the following features to improve the user experience:

Loading animation: Implement a loading animation to indicate the loading progress.
Progress bar: Implement a progress bar to indicate the loading progress.
Custom view: Implement a custom view to display the spinner and the map simultaneously.
