Why Are Your Text Content Not Visible in Android Jetpack Compose?

If you're diving into the world of Android Jetpack Compose, you may find yourself facing some unexpected challenges, particularly when it comes to displaying text on the screen. One common issue developers encounter is that their text content is simply not visible, while other UI elements appear just fine. If you've written some code but can't see your Text content, you're not alone.

In this guide, we’ll explore a specific case of this issue, investigate what may be going wrong, and provide a clear solution to make your text visible again.

The Problem: Invisible Text Content

You might have created a composable function to display several texts stacked vertically. Your structure might look something like this:

While you can see other components like buttons, your text elements are simply not showing up. What’s happening here?

Understanding the Root Cause

The issue fundamentally arises from two main factors:

Column Height is Too Small: Setting the height of your Column to 40.dp is not sufficient to contain all the text views you want to display. The spacing and elements inside need more height to be fully visible.

Order of Modifiers Matters: When you apply Modifier.padding(top = 120.dp) after setting a fixed height, you're attempting to push the content down within a container that can only hold 40.dp. Hence, there isn’t enough room to display everything.

Breaking Down the Problem

The Spacer and the Text components require additional vertical space:

The Spacer at 20.dp height takes away more space.

Each Text component also requires vertical space based on its defined size.

When fitting these into a Column restricted to 40.dp, elements are inevitably cut off.

The Solution: Adjusting Height and Layout

To resolve this visibility issue, you have two main options:

1. Remove the Height Modifier

The simplest approach is to remove the .height(40.dp) modifier altogether. This allows the height of the Column to adjust automatically based on its content.

2. Set a Larger Height

If you wish to keep a fixed height for your column, consider increasing it sufficiently to accommodate all contained elements. For instance:

Conclusion

By understanding how layout modifiers interact in Jetpack Compose and ensuring that your UI components have enough space to be displayed, you can avoid the frustration of invisible text content. Whether you choose to remove the height restriction or set a larger dimension, you’ll enjoy a visually coherent design.

If you find yourself struggling with UI issues like this, take a moment to inspect your layout parameters—often, small adjustments can lead to significant improvements.
