How to Display Edit Text Input as a Toast in Android

Creating a user-friendly interface often requires the display of information entered by the user. If you're working with Android and have a custom alert dialog that includes an EditText, you might want to show the entered text as a Toast message when a button is clicked. In this post, we’ll walk you through how to implement this functionality step by step.

Problem Statement

When you click the "Yes" button in a custom alert dialog that contains an EditText, the goal is to retrieve the input text and display it as a Toast message. Let's break down how we can achieve this using Java for Android development.

Solution Overview

To accomplish this, we will follow a series of organized steps:

Update the current dialog setup in your MainActivity.

Retrieve the text from the EditText when the button is clicked.

Display the text as a Toast message.

Step 1: Update Your Alert Dialog Code

We need to ensure that the dialog correctly inflates the dialog_layout so that we can access the EditText. Here’s the code to modify your dialog construction method within your MainActivity:

Step 2: Retrieve Text from EditText

In the above code, we retrieve the text from the EditText using view.findViewById(R.id.editTextInput). This approach is crucial because it ensures we are accessing the instance of EditText that belongs to the dialog layout we just inflated.

Step 3: Display the Toast Message

Once you've retrieved the input from the EditText, the next step is to display it as a Toast. This is done with the following line:

This line creates a Toast message that will pop up on the screen showing the PIN entered by the user.

Conclusion

Implementing functionality to display EditText input as a Toast in Android is straightforward once you properly reference the inflated view of your dialog. By following the steps above, you should now have a working example that provides a Toast message with the user input when they click "Yes" in your custom alert dialog.

Feel free to modify the design or add further functionalities as per your application's requirements. Happy coding!
