Fixing Your Android Studio EditText View: Why Input, Output, and Hints May Not Display
If you've been working with Android Studio and are experiencing issues with your EditText view, you're not alone. Many developers, especially those new to Android, face similar challenges. You might find that your EditText does not display the user's input, fails to show the expected output, or that the hint you've specified simply doesn't appear. So, what gives?
In this guide, we'll explore some common pitfalls associated with EditText and provide you with a solution to ensure it displays correctly.
Understanding the Problem
From the provided code snippets, the issue seems to stem from the configuration of the EditText in the XML layout. Here’s a brief recap of the symptoms:
The EditText does not show user input when typed.
The output does not display as intended.
The hint set for the EditText does not appear.
These problems can often be attributed to improperly set layout parameters or styles, which can restrict the view’s dimensions.
Step-by-Step Solution
To resolve these issues, we will make a few adjustments to both your XML layout file and your Java code. Follow these steps:
1. Adjusting XML Layout Attributes
In your XML layout for the EditText, the current dimensions are set to fixed measurements (40dp for width and 20dp for height). However, when you also set the layout_margin, it effectively reduces the visible area. Here’s the change you need to make:

2. Addressing the Java Code
To ensure that the user input is captured and displayed correctly, make sure you have the following logic in your button's OnClickListener:

3. Best Practices
Use wrap_content: This allows your views to adjust according to the content, avoiding issues where text might get clipped due to small dimensions.
Variable Naming: Consider changing your variable names to follow the camel case convention. For instance:

Hint Visibility: To enhance the contrast between your hint text and user input, consider changing the opacity of your hint color, making it easier to distinguish.
Conclusion
By following these guidelines, you should be able to fix your EditText so that it accurately displays user inputs and hints. Remember that the dimensions of your views are crucial for visibility, and always strive to write clean, maintainable code.
Should you continue experiencing issues, examine the entire layout file and configurations surrounding your EditText, as constraints and other attributes may influence its behavior.
Happy coding!
