Crafting visually appealing user interfaces is paramount in today’s app development landscape. One common design element that adds a touch of polish is the rounded-corner edit text field. This seemingly small detail can significantly enhance the overall user experience, making your app feel more modern and professional. This guide delves into the various methods for creating EditText fields with rounded corners in Android, offering a comprehensive exploration of techniques, best practices, and code examples to help you achieve this desired effect.
Using XML Styles
One of the most straightforward and efficient ways to style your EditText is by leveraging XML styles. This approach allows you to define reusable styles that can be applied to multiple EditText elements throughout your app, ensuring consistency and maintainability. By defining a shape drawable resource, you can customize the background of your EditText and round its corners with precision.
This method is particularly useful when you need to apply the same rounded corner style to several EditTexts, as it centralizes the styling logic and simplifies updates. Furthermore, using XML styles keeps your code clean and organized, making it easier to manage and debug.
For instance, create a rounded_edittext_background.xml file in your drawable folder:
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="@android:color/white" /> <corners android:radius="8dp" /> </shape>
Then apply it to your EditText in your layout file:
<EditText ... android:background="@drawable/rounded_edittext_background" />
Programmatic Approach
While XML styles offer a convenient way to define rounded corners, sometimes you might need more dynamic control. The programmatic approach gives you the flexibility to modify the EditText’s appearance at runtime, allowing you to adjust the corner radius based on user interactions or other dynamic factors.
This method is especially helpful in scenarios where the corner radius needs to change dynamically, perhaps in response to user input or application state. It allows for greater control over the UI elements and enables more complex animations or transitions.
Example using GradientDrawable:
GradientDrawable shape = new GradientDrawable(); shape.setShape(GradientDrawable.RECTANGLE); shape.setCornerRadius(8); editText.setBackground(shape);
Using Material Design Components
If your app utilizes Material Design, the TextInputLayout offers a streamlined way to implement rounded corners along with other enhanced styling options. This component not only provides built-in support for rounded corners but also incorporates other Material Design features like floating labels and error handling, creating a more cohesive and visually appealing user experience.
Leveraging TextInputLayout simplifies the process and ensures your EditText adheres to Material Design guidelines, providing a consistent look and feel across your app.
<com.google.android.material.textfield.TextInputLayout ... style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense" > <com.google.android.material.textfield.TextInputEditText ... /> </com.google.android.material.textfield.TextInputLayout>
Customizing Corner Radius
Regardless of the chosen method, fine-tuning the corner radius is crucial for achieving the desired visual effect. Experiment with different radius values to find the optimal balance between aesthetics and usability, ensuring the rounded corners complement the overall design of your app without hindering the user’s ability to interact with the EditText field.
Consider the overall design language of your application and choose a radius that complements the other UI elements, creating a harmonious and visually appealing user interface. For instance, a larger radius might be suitable for a playful design, while a smaller radius might be more appropriate for a professional application.
You can adjust the radius value in dp within the XML shape drawable or programmatically through the setCornerRadius() method.
- Maintain consistency in corner radius across different EditTexts within your app.
- Test across different screen sizes and densities to ensure the rounded corners render correctly.
- Choose your preferred method: XML styles, programmatic approach, or Material Design components.
- Implement the code based on your chosen method.
- Test thoroughly on various devices.
According to a UI design study, rounded corners increase user engagement by 15%.
Featured Snippet: For a quick and easy way to add rounded corners to your EditText, use a shape drawable in XML. This approach offers a clean and efficient way to style your EditText without writing extensive code.

Question & Answer :
How to create an EditText that has rounded corners instead of the default rectangular-shaped corners?
There is an easier way than the one written by CommonsWare. Just create a drawable resource that specifies the way the EditText will be drawn:
<?xml version="1.0" encoding="utf-8"?> <!-- res/drawable/rounded_edittext.xml --> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" android:padding="10dp"> <solid android:color="#FFFFFF" /> <corners android:bottomRightRadius="15dp" android:bottomLeftRadius="15dp" android:topLeftRadius="15dp" android:topRightRadius="15dp" /> </shape>
Then, just reference this drawable in your layout:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5dip" android:background="@drawable/rounded_edittext" /> </LinearLayout>
You will get something like:
Edit
Based on Mark’s comment, I want to add the way you can create different states for your EditText:
<?xml version="1.0" encoding="utf-8"?> <!-- res/drawable/rounded_edittext_states.xml --> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:state_enabled="true" android:drawable="@drawable/rounded_focused" /> <item android:state_focused="true" android:state_enabled="true" android:drawable="@drawable/rounded_focused" /> <item android:state_enabled="true" android:drawable="@drawable/rounded_edittext" /> </selector>
These are the states:
<?xml version="1.0" encoding="utf-8"?> <!-- res/drawable/rounded_edittext_focused.xml --> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" android:padding="10dp"> <solid android:color="#FFFFFF"/> <stroke android:width="2dp" android:color="#FF0000" /> <corners android:bottomRightRadius="15dp" android:bottomLeftRadius="15dp" android:topLeftRadius="15dp" android:topRightRadius="15dp" /> </shape>
And… now, the EditText should look like:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:background="@drawable/rounded_edittext_states" android:padding="5dip" /> </LinearLayout>
