How to Display Selected Time in React Native DateTimePicker

If you’re working on a React Native application, you may want to customize the behavior of the DateTimePicker to allow users to select a specific time instead of always defaulting to the current time. This can be crucial for applications that require precise time management. In this guide, we’ll address how to set up the DateTimePicker so that it shows the time you provide when the user interacts with it. Let’s dive into this issue and its solution.

The Problem Explained

You may have encountered a scenario where, upon clicking a button to open a Time Picker, the displayed time doesn't reflect the user's choice. Rather than showing a preset time, the DateTimePicker defaults to the current time, which can be inconvenient for users who expect to see their chosen time right away. For instance, if you want to preset the time to 9:00 PM (21:00 in 24-hour format), you need to configure your component accordingly.

Example Scenario:

User clicks the button to open the Time Picker.

Current default time shows up instead of the anticipated 9:00 PM.

The Solution Steps

Here’s how to solve this issue step-by-step.

1. Set up the component state

Start by defining the necessary state variables in your functional component. You'll need to keep track of the selected time and whether the picker should be visible or not.

2. Handling Time Selection

When the user selects a time, you will want to capture that specific time instead of the current one. Here's how you set it up:

3. Show the Time Picker with Preset Time

Now we will implement the function that guarantees it displays the required time:

4. Configuring the DateTimePicker

Here’s the key part: ensure you adjust the is24Hour prop of the DateTimePicker. Set it to false to maintain the 12-hour format with AM and PM.

Conclusion

By following the steps above, you can successfully customize the React Native DateTimePicker to reflect the time that the user has selected, rather than defaulting to the new date and time. This allows for a more intuitive user experience, especially in time-sensitive applications. Don’t forget to set the is24Hour prop to false for a cleaner display of hours in the 12-hour format!

With this knowledge, you can enhance your app's functionality and provide your users with a seamless and user-friendly interface. Happy coding!
