afohrman f2ebf56e21 Rename text field outlined style from "Outline" to "Outlined".

This commit updates the style names for the outlined text field box from "Outline" to "Outlined.

Widget.MaterialComponents.TextInputLayout.OutlineBox -> Widget.MaterialComponents.TextInputLayout.OutlinedBox, and
Widget.MaterialComponents.TextInputEditText.OutlineBox -> Widget.MaterialComponents.TextInputEditText.OutlinedBox.

This name matches spec and is closer to what is used on the other platforms.

Text Fields

TextInputLayout provides an implementation for Material text fields. Used in conjunction with a TextInputEditText, TextInputLayout makes it easy to include Material text fields in your layouts.

Design & API Documentation

Usage

To create a material text field, add a TextInputLayout to your XML layout and a TextInputEditText as a direct child.

<com.google.android.material.textfield.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

  <com.google.android.material.textfield.TextInputEditText
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:hint="@string/hint_text"/>

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

Note: An EditText may work for your input text component. However, using TextInputEditText allows TextInputLayout greater control over the visual aspects of the input text and provides accessibility support for the text field.

Material Styles

Using TextInputLayout with an updated Material theme (Theme.MaterialComponents) will provide the correct updated Material styles to your text fields by default. If you need to use an updated Material text field and your application theme does not inherit from an updated Material theme, you can apply one of the updated Material styles directly to your widget in XML.

Filled Box (Default)

Filled text fields have a solid background color and draw more attention, especially in layouts where the field is surrounded by other elements. To use a filled text field, apply the following style to your TextInputLayout:

style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox"

To change the background color of a filled text field, you can set the boxBackgroundColor attribute on your TextInputLayout.

Outline Box

Outline text fields have a stroked border and are less emphasized. To use an outline text field, apply the following style to your TextInputLayout:

style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"

To change the stroke color and width for an outline text field, you can set the boxStrokeColor and boxStrokeWidth attributes on your TextInputLayout, respectively.

Height Variations

TextInputLayout provides two height variations for filled and outline text fields, standard and dense. Both box styles default to the standard height.

In order to reduce the height of a text box, you can use a dense style, which will reduce the vertical padding within the text box. You can achieve this by applying the appropriate styles to your TextInputLayout and TextInputEditText, depending on whether you are using a filled or outline text field:

Dense Filled Box

Apply this style to your TextInputLayout: xml style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.Dense"

Dense Outline Box

Apply this style to your TextInputLayout: xml style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"

To change a text box's internal padding and overall dimensions, you can adjust the android:padding attributes on the TextInputEditText.

Corner Radius

boxCornerRadiusTopLeft
boxCornerRadiusTopRight
boxCornerRadiusBottomLeft
boxCornerRadiusBottomRight

Common features

TextInputLayout provides functionality for a number of Material text field features. These are some commonly used properties you can update to control the look of your text field:

Text field element	Relevant attributes/methods
Label (also called a “Floating Label”)	`android:hint` `app:hintEnabled`
Error message	`app:errorEnabled` `#setError(CharSequence)`
Helper text	`app:helperTextEnabled` `app:helperText`
Password redaction	`app:passwordToggleEnabled` `app:passwordToggleDrawable`
Character counter	`app:counterEnabled` `app:counterMaxLength`

Notes about setting the hint

If a hint is specified on the child EditText in XML, then the TextInputLayout will use the EditText's hint as its floating label. To specify or change the hint programmatically, make sure to call the setHint() method on TextInputLayout, instead of on the EditText.

Notes about using `TextInputLayout` and `TextInputEditText` programmatically

If you construct a TextInputEditText programmatically, you should use TextInputLayout's context to create the view. This will allow TextInputLayout to pass along the appropriate styling to the TextInputEditText.

TextInputEditText editText = new TextInputEditText(textInputLayout.getContext());
