In this tutorial, we’ll implement Text Fields using the new Material Design Components Library. We have already implemented TextInputLayout here.
TextInputLayout provides an implementation for Material text fields. We just need to use TextInputEditText! First and foremost, import the new material components dependency. Also, set the MaterialComponent theme in your Activity.
implementation 'com.google.android.material:material:1.1.0-alpha09'
By default, an input text field has a filled background to draw users attention. Now let’s create a default text field:
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Filled box(default)">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
In the next few sections, we’ll customize text fields in different ways.
Text Fields have two types of height variants:
@style/Widget.MaterialComponents.TextInputLayout.FilledBox.Dense
The dense Text field is slightly shorter in height.
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Filled box(default)">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
<com.google.android.material.textfield.TextInputLayout
style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.Dense"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Filled box dense"
app:boxBackgroundColor="#20D81B60">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
By default the FilledBox.Standard
style is used app:boxBackgroundColor
is used to set the filled box color. Here’s how this looks on the screen:
Apply the following style on the TextInputLayout to get the outlined look text fields:
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
Similar to FilledBox, this has the two height variants as well - Standard and Dense. To set the corner radius, following attributes are used:
boxStrokeColor
is used to set the stroke color of the outline. Here’s how it looks:
Moving forward, now let’s set end icon modes. These are basically icons set at the right of the text field. Currently, the three types of icons that are available built-in are :
password_toggle
clear_text
custom
The above attributes are self-explanatory. We can set our own icon tint on these icons using endIconTint
attribute. For the custom icon, we use the endIconDrawable
attribute
<com.google.android.material.textfield.TextInputLayout
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Enter password"
app:endIconMode="password_toggle">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
<com.google.android.material.textfield.TextInputLayout
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Enter password"
app:endIconMode="password_toggle"
app:endIconTint="@color/colorAccent">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
<com.google.android.material.textfield.TextInputLayout
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Clear text"
app:endIconMode="clear_text"
app:endIconTint="@color/colorPrimaryDark">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
<com.google.android.material.textfield.TextInputLayout
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:hint="Custom end icon"
app:endIconCheckable="true"
android:id="@+id/custom_end_icon"
app:endIconDrawable="@android:drawable/ic_input_add"
app:endIconMode="custom"
app:endIconTint="@color/colorPrimaryDark">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
Here’s how it looks on the screen:
For the custom icon, we can use setEndIconOnClickListener
callback to listen to clicks and do stuff.
ShapeAppearance is a powerful style. It lets us customize the shape of the text field. We have two built-in shapes - cut and round.
<style name="Cut" parent="ShapeAppearance.MaterialComponents.MediumComponent">
<item name="cornerFamily">cut</item>
<item name="cornerSize">12dp</item>
</style>
<style name="Rounded" parent="ShapeAppearance.MaterialComponents.SmallComponent">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">16dp</item>
</style>
Setting the above styles in the shapeAppearance
attributes gives us this -
That sums up Material Components Text Fields for now. In the below source code you’ll find all the above concepts.
