Show/Hide Password in EditText in Android

This feature allows users to toggle between displaying the password in plain text and hiding it behind asterisks or dots.

1. Create an EditText in your layout XML file:

EditText
    android:id="@+id/passwordEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textPassword"
    android:hint="Enter your password"

2. Define a boolean flag to track the password visibility state:

boolean isPasswordVisible = false;

3. Create a method to toggle password visibility:

private void togglePasswordVisibility() {
    EditText passwordEditText = findViewById(R.id.passwordEditText);
    if (isPasswordVisible) {
        // If password is visible, hide it by setting the input type to textPassword
        passwordEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        isPasswordVisible = false;
    } else {
        // If password is hidden, show it by setting the input type to text
        passwordEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
        isPasswordVisible = true;
    }
    // Move the cursor to the end of the text to maintain the current position
    passwordEditText.setSelection(passwordEditText.getText().length());
}

4. Set an OnClickListener to the EditText to toggle password visibility when a user clicks an eye icon or any other view:

EditText passwordEditText = findViewById(R.id.passwordEditText);
ImageView togglePasswordVisibilityImageView = findViewById(R.id.togglePasswordVisibilityImageView); // Replace with your eye icon or view
togglePasswordVisibilityImageView.setOnClickListener(v -> togglePasswordVisibility());

5. You're done! Now, when the user clicks the eye icon or view, the password visibility will toggle between hidden and visible.
