EditText is a fundamental UI element in Android that allows users to input text. This guide will help you read data from EditText using Java in Android Studio, perfect for beginner Android developers.

Step-by-Step Guide

1. Add EditText and Button in XML Layout

Create or open your XML layout file (e.g., activity_main.xml) and add the following UI elements:

<EditText
    android:id="@+id/editTextName"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Enter your name" />

<Button
    android:id="@+id/buttonSubmit"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Submit" />

2. Access EditText and Button in Java Code

In your activity class (e.g., MainActivity.java), declare and initialize the views:

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    EditText editTextName;
    Button buttonSubmit;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize the views
        editTextName = findViewById(R.id.editTextName);
        buttonSubmit = findViewById(R.id.buttonSubmit);

        // Set a click listener
        buttonSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Read text from EditText
                String name = editTextName.getText().toString();

                // Display using Toast
                Toast.makeText(MainActivity.this, "Hello, " + name, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

3. Key Methods Explained

• • findViewById(): Links the XML view to Java.
  • getText().toString(): Retrieves the text input from EditText.
  • Toast.makeText(): Displays a small message popup (optional).

Summary

Reading data from an EditText in Java using Android Studio is simple and essential. You:

• • Declare EditText and Button
  • Use getText().toString() to retrieve the text
  • Use it for displaying, processing, or saving

Now you’re ready to handle user input like a pro!
