Theming of Material Design EditText in Android with Example

Theming the EditText widget, particularly when you're using the Material Design components, can significantly enhance the visual appeal and user experience of your app. Here's a step-by-step guide to theme the Material Design TextInputLayout and TextInputEditText in Android:

1. Prerequisites:

Ensure you have the Material Components library in your build.gradle:

implementation 'com.google.android.material:material:<version>'

Replace <version> with the appropriate library version.

Make sure your app's theme inherits from a Material Components theme, such as Theme.MaterialComponents.Light.DarkActionBar.

2. Using the TextInputLayout and TextInputEditText:

To achieve a Material Design-styled EditText, you'd typically wrap a TextInputEditText within a TextInputLayout:

<com.google.android.material.textfield.TextInputLayout
    android:id="@+id/textInputLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Enter your name">

    <com.google.android.material.textfield.TextInputEditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</com.google.android.material.textfield.TextInputLayout>

3. Theming:

A. Using XML Styles:

You can define a style in your res/values/styles.xml:

<!-- Theme for TextInputLayout -->
<style name="CustomTextInputLayout" parent="Widget.MaterialComponents.TextInputLayout.FilledBox">
    <item name="boxBackgroundColor">@color/boxBackgroundColor</item>
    <item name="boxStrokeColor">@color/boxStrokeColor</item>
    <item name="hintTextColor">@color/hintColor</item>
    <item name="errorTextColor">@color/errorColor</item>
    <item name="boxStrokeErrorColor">@color/boxErrorColor</item>
</style>

<!-- Theme for TextInputEditText -->
<style name="CustomEditText" parent="Widget.MaterialComponents.TextInputEditText.FilledBox">
    <item name="android:textColor">@color/textColor</item>
</style>

Apply these styles in your XML layout:

<com.google.android.material.textfield.TextInputLayout
    style="@style/CustomTextInputLayout"
    ...>

    <com.google.android.material.textfield.TextInputEditText
        style="@style/CustomEditText"
        ... />

</com.google.android.material.textfield.TextInputLayout>

B. Programmatically:

val textInputLayout: TextInputLayout = findViewById(R.id.textInputLayout)
val editText: TextInputEditText = findViewById(R.id.editText)

textInputLayout.boxBackgroundColor = ContextCompat.getColor(this, R.color.boxBackgroundColor)
textInputLayout.boxStrokeColor = ContextCompat.getColor(this, R.color.boxStrokeColor)
textInputLayout.defaultHintTextColor = ColorStateList.valueOf(ContextCompat.getColor(this, R.color.hintColor))

editText.setTextColor(ContextCompat.getColor(this, R.color.textColor))

These are the basic steps to theme the TextInputLayout and TextInputEditText in your Android app. Remember, Material Components offer a lot of attributes for customizing the appearance of these widgets. Always refer to the official documentation for the most up-to-date theming guidance and comprehensive attribute lists.
