How to remove padding for the bottom line of the TextInputEditText

I'm trying to remove all padding of a TextInputLayout and a TextInputEditText, but with padding=0dp the line at the bottom of the TextInputEditText keeps it padding left and right. How I can remove this padding?
This is the xml code that I've used.
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/ti_input_otp"
android:layout_width="0dp"
android:layout_height="wrap_content"

app:hintTextAppearance="#style/FloatingLabel"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/tv_input_otp_description">
<com.google.android.material.textfield.TextInputEditText

Thank you

You can use your own custom style for TextInputLayout as below:
Your layout:
<com.google.android.material.textfield.TextInputLayout
....
android:hint="Your hint text"
style="#style/My.TextInputLayout.Theme" >
Then define your custom theme as below:
<style name="My.TextInputLayout.Theme" parent="Widget.MaterialComponents.TextInputLayout.FilledBox">
<item name="materialThemeOverlay">#style/MyThemePadding</item>
</style>
<style name="MyThemePadding">
<item name="editTextStyle">#style/MyTextInputEditText_padding</item>
</style>
<style name="MyTextInputEditText_padding" parent="#style/Widget.MaterialComponents.TextInputEditText.FilledBox">
<!-- Set left and right padding here -->
<item name="android:paddingStart" ns2:ignore="NewApi">2dp</item>
<item name="android:paddingEnd" ns2:ignore="NewApi">2dp</item>
<item name="android:paddingLeft">2dp</item>
<item name="android:paddingRight">2dp</item>
<!-- Set top and bottom padding here -->
<item name="android:paddingTop">28dp</item>
<item name="android:paddingBottom">12dp</item>
</style>

How can I change the background color of the hint text of TextInputLayout

I am programming a view of TextInputLayout
My style.xml is :
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="MyTextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense">
<item name="boxStrokeColor">#color/colorPrimary</item>
<item name="hintTextColor">#color/colorPrimary</item>
<item name="boxBackgroundColor">#android:color/white</item>
<item name="boxStrokeWidth">2dp</item>
</style>
</resources>
My color overrides in color.xml are:
<color name="mtrl_textinput_default_box_stroke_color" tools:override="true">#c2261a</color>
My TextInput Layout is:
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/weightInput"
style="#style/MyTextInputLayoutStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:layout_marginBottom="15dp"
android:hint="#string/hint_weight"
app:errorEnabled="true"
app:helperTextEnabled="false"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/textViewTitle">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:imeOptions="actionDone"
android:importantForAutofill="no"
android:inputType="numberDecimal"
android:maxLength="5"
android:maxLines="1"
android:singleLine="true"
android:textAlignment="center"
android:textColor="#color/colorPrimary" />
</com.google.android.material.textfield.TextInputLayout>
And the final result is
As we can see the background color of the hint text is transparent. How can I find that view.
I tried that style without success:
My style.xml is :
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>

Updating to material components 1.4.0-alpha01 resolves this issue.
This is the commit responsible: https://github.com/material-components/material-components-android/commit/6015a4e901dc55a02f86e12703820d520684f95e

Its Works for me.. I wish its also works for you..
<EditText
android:layout_width="match_parent"
android:layout_height="50dp"

android:hint="Add Your Text Watermark"
android:textColorHint="#color/yellowcolor" // this line can change hint text color
android:textColor="#color/yellowcolor"
android:fontFamily="#font/inter_light"
android:textAlignment="center"/>

This is to change the line color of edit text.
android:backgroundTint="#color/colorPrimaryDark"

how to change google.android.material.textfield.TextInputLayout line colour [duplicate]

I am using android design library's TextinputLayout. But couldn't customize the hint color, label color and the underline color of EditText inside TextinputLayout. Please help.

Change bottom line color:
From this answer
<item name="colorControlNormal">#c5c5c5</item>
<item name="colorControlActivated">#color/accent</item>
<item name="colorControlHighlight">#color/accent</item>
Change hint color when it is floating
<style name="MyHintStyle" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/main_color</item>
</style>
and use it like this:
<android.support.design.widget.TextInputLayout
...
app:hintTextAppearance="#style/MyHintStyle">
Change hint color when it is not a floating label:
<android.support.design.widget.TextInputLayout
...
app:hintTextAppearance="#style/MyHintStyle"
android:textColorHint="#c1c2c4">
Thanks to #AlbAtNf

With the Material Components Library you can use the com.google.android.material.textfield.TextInputLayout.
You can apply a custom style to change the colors.
To change the hint color you have to use these attributes:
hintTextColor and android:textColorHint.
<style name="Custom_textinputlayout_filledbox" parent="#style/Widget.MaterialComponents.TextInputLayout.FilledBox">
<!-- The color of the label when it is collapsed and the text field is active -->
<item name="hintTextColor">?attr/colorPrimary</item>
<!-- The color of the label in all other text field states (such as resting and disabled) -->
<item name="android:textColorHint">#color/selector_hint_text_color</item>
</style>
You should use a selector for the android:textColorHint. Something like:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:alpha="0.38" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
<item android:alpha="0.6" android:color="?attr/colorOnSurface"/>
</selector>
To change the bottom line color you have to use the attribute: boxStrokeColor.
<style name="Custom_textinputlayout_filledbox" parent="#style/Widget.MaterialComponents.TextInputLayout.FilledBox">
....
<item name="boxStrokeColor">#color/selector_stroke_color</item>
</style>
Also in this case you should use a selector. Something like:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="?attr/colorPrimary" android:state_focused="true"/>
<item android:alpha="0.87" android:color="?attr/colorOnSurface" android:state_hovered="true"/>
<item android:alpha="0.12" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
<item android:alpha="0.38" android:color="?attr/colorOnSurface"/>
</selector>
You can also apply these attributes in your layout:
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.FilledBox"
app:boxStrokeColor="#color/selector_stroke_color"
app:hintTextColor="?attr/colorPrimary"
android:textColorHint="#color/selector_hint_text_color"
...>

Based on Fedor Kazakov and others answers, I created a default config.

Add this attribute in Edittext tag and enjoy:
android:backgroundTint="#color/colorWhite"

This Blog Post describes various styling aspects of EditText and AutoCompleteTextView wrapped by TextInputLayout.
For EditText and AppCompat lib 22.1.0+ you can set theme attribute with some theme related settings:
<style name="StyledTilEditTextTheme">
<item name="android:imeOptions">actionNext</item>
<item name="android:singleLine">true</item>
<item name="colorControlNormal">#color/greyLight</item>
<item name="colorControlActivated">#color/blue</item>
<item name="android:textColorPrimary">#color/blue</item>
<item name="android:textSize">#dimen/styledtil_edit_text_size</item>
</style>
<style name="StyledTilEditText">
<item name="android:theme">#style/StyledTilEditTextTheme</item>
<item name="android:paddingTop">4dp</item>
</style>
and apply them on EditText:
<EditText
android:id="#+id/etEditText"
style="#style/StyledTilEditText"
For AutoCompleteTextView things are more complicated because wrapping it in TextInputLayout and applying this theme breaks floating label behaviour.
You need to fix this in code:
private void setStyleForTextForAutoComplete(int color) {
Drawable wrappedDrawable = DrawableCompat.wrap(autoCompleteTextView.getBackground());
DrawableCompat.setTint(wrappedDrawable, color);
autoCompleteTextView.setBackgroundDrawable(wrappedDrawable);
}
and in Activity.onCreate:
setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
autoCompleteTextView.setOnFocusChangeListener((v, hasFocus) -> {
if(hasFocus) {
setStyleForTextForAutoComplete(getResources().getColor(R.color.blue));
} else {
if(autoCompleteTextView.getText().length() == 0) {
setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
}
}
});

If you want to change the bar/line color and the hint text color of the TextInputLayout (what the accent color normally is), then just create this style:
<style name="MyStyle">
<item name="colorAccent">#color/your_color</item>
</style>
Then apply it to your TextInputLayout as a theme:
<android.support.design.widget.TextInputLayout
...
app:theme="#style/MyStyle" />
This basically sets a theme (not style) to one view (as opposed to the whole activity).

A TextinputLayout is not a view, but a Layout, as very nicely described by Dimitrios Tsigouris in his blog post here. Therefore, you don't need a Style, which is for Views only, but use a Theme. Following the blog post, I ended up with the following solution:
Start in your styles.xml with
<style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
<!-- reference our hint & error styles -->
<item name="android:textColor">#color/your_colour_here</item>
<item name="android:textColorHint">#color/your_colour_here</item>
<item name="colorControlNormal">#color/your_colour_here</item>
<item name="colorControlActivated">#color/your_colour_here</item>
<item name="colorControlHighlight">#color/your_colour_here</item>
</style>
And in your layout add
<com.google.android.material.textfield.TextInputLayout
android:theme="#style/TextInputLayoutAppearance"
...

<style name="Widget.Design.TextInputLayout" parent="android:Widget">
<item name="hintTextAppearance">#style/TextAppearance.Design.Hint</item>
<item name="errorTextAppearance">#style/TextAppearance.Design.Error</item>
</style>
You can override this style for layout
And also you can change inner EditText-item style too.

<style name="EditScreenTextInputLayoutStyle" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorControlNormal">#color/actionBar_background</item>
<item name="colorControlActivated">#color/actionBar_background</item>
<item name="colorControlHighlight">#color/actionBar_background</item>
<item name="colorAccent">#color/actionBar_background</item>
<item name="android:textColorHint">#color/actionBar_background</item>
</style>
apply this style to TextInputLayout

I used all of the above answers and none worked. This answer works for API 21+. Use app:hintTextColor attribute when text field is focused and app:textColorHint attribute when in other states. To change the bottmline color use this attribute app:boxStrokeColor as demonstrated below:
<com.google.android.material.textfield.TextInputLayout
app:boxStrokeColor="#color/colorAccent"
app:hintTextColor="#color/colorAccent"
android:textColorHint="#android:color/darker_gray"
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
It works for AutoCompleteTextView as well. Hope it works for you:)

Works for me. If you trying EditText with Label and trying change to underline color use this. Change to TextInputEditText instead EditText.
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/editTextTextPersonName3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="#dimen/_16sdp"
android:layout_marginLeft="#dimen/_16sdp"
android:layout_marginTop="#dimen/_16sdp"
android:layout_marginEnd="#dimen/_8sdp"
android:layout_marginRight="#dimen/_8sdp"
android:textColorHint="#color/white"
app:layout_constraintEnd_toStartOf="#+id/guideline3"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:backgroundTint="#color/white"
android:hint="Lastname"
android:textSize="#dimen/_14sdp"
android:inputType="textPersonName"
android:textColor="#color/white"
android:textColorHint="#color/white" />
</com.google.android.material.textfield.TextInputLayout>

Change line color of TextInputLayout + TextInputEditText
colors.xml
<color name="mtrl_textinput_default_box_stroke_color" tools:override="true">#color/lineColor</color>
styles.xml
<style name="TextInputLayout" parent="Widget.MaterialComponents.TextInputLayout.FilledBox.Dense">
<item name="boxStrokeColor">#color/lineColor</item>
<item name="android:textColorHint">#color/hintColor</item>
<item name="boxStrokeWidth">1dp</item>
<item name="boxBackgroundColor">#color/backgroundColor</item>
</style>
<style name="TextInputEditText" parent="ThemeOverlay.MaterialComponents.TextInputEditText.FilledBox.Dense">
<item name="android:textColor">#color/black</item>
</style>
layout.xml
<com.google.android.material.textfield.TextInputLayout
style="#style/TextInputLayout"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<com.google.android.material.textfield.TextInputEditText
style="#style/TextInputEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text" />
</com.google.android.material.textfield.TextInputLayout>

You can change the label color of TextInputLayout by using app:hintTextAppearance attribute in TextInputLayout.
<android.support.design.widget.TextInputLayout
android:id="#+id/inputlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintTextAppearance="#style/TextAppearance.App.TextInputLayout">
<EditText
android:id="#+id/mail"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:hint="#string/email"
android:inputType="textEmailAddress"
android:maxLines="1"
android:paddingStart="5dp"
android:singleLine="true"/>
</android.support.design.widget.TextInputLayout>
Style:
<style name="TextAppearance.App.TextInputLayout"
parent="#android:style/TextAppearance">
<item name="android:textColor">#android:color/black</item>
<item name="android:textSize">20sp</item>
</style>
To change edittext underline color, you can use android:backgroundTint
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Underline color change"
android:backgroundTint="#android:color/holo_red_light" />

Create style as mentioned below
<style name="text_input_layout_style">
<item name="colorControlNormal">#color/primary</item>
<item name="colorControlActivated">#color/primary</item>
<item name="colorControlHighlight">#color/primary</item>
</style>
and apply it to your TextInputLayout as android:theme="#style/text_input_layout_style"
And definitely will work for you all.

I needed to change the bottom line color of a TextInputEditText inside a TextInputLayout and then the other answers didn't work out. I finally solved it by setting the colorOnSurface for the TextInputLayouts theme. I'll leave my code here in case it helps someone else.

How to reduce the line size of Floating Label EditText when it is in active state

Here I am using Floating Label EditText. I need to edit the size of the line under the EditText when I enter any text into that text field. Here I have added the code for your reference
This is the code in XML
<android.support.design.widget.TextInputLayout
android:id="#+id/input_layout_last"
android:layout_width="match_parent"
android:layout_height="70dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:layout_marginTop="10dp">
<EditText
android:id="#+id/input_last"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:textSize="12sp"
android:paddingLeft="20dp"
android:theme="#style/MyEditTheme"
android:textColor="#color/white"
android:textColorHint="#color/white"
android:hint="Password" />
</android.support.design.widget.TextInputLayout>
This my style.xml
<resources>
<style name="MyMaterialTheme" parent="MyMaterialTheme.Base">
</style>
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>

<item name="android:textColorHint">#color/white</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="MyEditTheme" parent="MyMaterialTheme.Base">
<!-- Used for the bottom line when not selected / focused -->
<item name="colorControlNormal">#383838</item>
<!-- colorControlActivated & colorControlHighlight use the colorAccent color by default -->
</style>
</resources>
Here I need to reduce the size of the blue line.

With the Material Components Library you can use the com.google.android.material.textfield.TextInputLayout.
You can apply a custom style to change the colors.
To change the hint color you have to use these attributes:
hintTextColor and android:textColorHint.
<style name="Custom_textinputlayout_filledbox" parent="#style/Widget.MaterialComponents.TextInputLayout.FilledBox">
<!-- The color of the label when it is collapsed and the text field is active -->
<item name="hintTextColor">?attr/colorPrimary</item>
<!-- The color of the label in all other text field states (such as resting and disabled) -->
<item name="android:textColorHint">#color/selector_hint_text_color</item>
</style>
You should use a selector for the android:textColorHint. Something like:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:alpha="0.38" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
<item android:alpha="0.6" android:color="?attr/colorOnSurface"/>
</selector>
To change the bottom line color you have to use the attribute: boxStrokeColor.
<style name="Custom_textinputlayout_filledbox" parent="#style/Widget.MaterialComponents.TextInputLayout.FilledBox">
....
<item name="boxStrokeColor">#color/selector_stroke_color</item>
</style>
Also in this case you should use a selector. Something like:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="?attr/colorPrimary" android:state_focused="true"/>
<item android:alpha="0.87" android:color="?attr/colorOnSurface" android:state_hovered="true"/>
<item android:alpha="0.12" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
<item android:alpha="0.38" android:color="?attr/colorOnSurface"/>
</selector>
You can also apply these attributes in your layout:
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.FilledBox"
app:boxStrokeColor="#color/selector_stroke_color"
app:hintTextColor="?attr/colorPrimary"
android:textColorHint="#color/selector_hint_text_color"

This Blog Post describes various styling aspects of EditText and AutoCompleteTextView wrapped by TextInputLayout.
For EditText and AppCompat lib 22.1.0+ you can set theme attribute with some theme related settings:
<style name="StyledTilEditTextTheme">
<item name="android:imeOptions">actionNext</item>
<item name="android:singleLine">true</item>
<item name="colorControlNormal">#color/greyLight</item>
<item name="colorControlActivated">#color/blue</item>
<item name="android:textColorPrimary">#color/blue</item>
<item name="android:textSize">#dimen/styledtil_edit_text_size</item>
</style>
<style name="StyledTilEditText">
<item name="android:theme">#style/StyledTilEditTextTheme</item>
<item name="android:paddingTop">4dp</item>
</style>
and apply them on EditText:
<EditText
android:id="#+id/etEditText"
style="#style/StyledTilEditText"
For AutoCompleteTextView things are more complicated because wrapping it in TextInputLayout and applying this theme breaks floating label behaviour.
You need to fix this in code:
private void setStyleForTextForAutoComplete(int color) {
Drawable wrappedDrawable = DrawableCompat.wrap(autoCompleteTextView.getBackground());
DrawableCompat.setTint(wrappedDrawable, color);
autoCompleteTextView.setBackgroundDrawable(wrappedDrawable);
}
and in Activity.onCreate:
setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
autoCompleteTextView.setOnFocusChangeListener((v, hasFocus) -> {
if(hasFocus) {
setStyleForTextForAutoComplete(getResources().getColor(R.color.blue));
} else {
if(autoCompleteTextView.getText().length() == 0) {
setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
}
}
});

If you want to change the bar/line color and the hint text color of the TextInputLayout (what the accent color normally is), then just create this style:
<style name="MyStyle">
<item name="colorAccent">#color/your_color</item>
</style>
Then apply it to your TextInputLayout as a theme:
<android.support.design.widget.TextInputLayout
...
app:theme="#style/MyStyle" />
This basically sets a theme (not style) to one view (as opposed to the whole activity).

A TextinputLayout is not a view, but a Layout, as very nicely described by Dimitrios Tsigouris in his blog post here. Therefore, you don't need a Style, which is for Views only, but use a Theme. Following the blog post, I ended up with the following solution:
Start in your styles.xml with
<style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
<!-- reference our hint & error styles -->
<item name="android:textColor">#color/your_colour_here</item>
<item name="android:textColorHint">#color/your_colour_here</item>
<item name="colorControlNormal">#color/your_colour_here</item>
<item name="colorControlActivated">#color/your_colour_here</item>
<item name="colorControlHighlight">#color/your_colour_here</item>
</style>
And in your layout add
<com.google.android.material.textfield.TextInputLayout
android:theme="#style/TextInputLayoutAppearance"
...

<style name="Widget.Design.TextInputLayout" parent="android:Widget">
<item name="hintTextAppearance">#style/TextAppearance.Design.Hint</item>
<item name="errorTextAppearance">#style/TextAppearance.Design.Error</item>
</style>
You can override this style for layout
And also you can change inner EditText-item style too.

<style name="EditScreenTextInputLayoutStyle" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorControlNormal">#color/actionBar_background</item>
<item name="colorControlActivated">#color/actionBar_background</item>
<item name="colorControlHighlight">#color/actionBar_background</item>
<item name="colorAccent">#color/actionBar_background</item>
<item name="android:textColorHint">#color/actionBar_background</item>
</style>
apply this style to TextInputLayout

I used all of the above answers and none worked. This answer works for API 21+. Use app:hintTextColor attribute when text field is focused and app:textColorHint attribute when in other states. To change the bottmline color use this attribute app:boxStrokeColor as demonstrated below:
<com.google.android.material.textfield.TextInputLayout
app:boxStrokeColor="#color/colorAccent"
app:hintTextColor="#color/colorAccent"
android:textColorHint="#android:color/darker_gray"
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
It works for AutoCompleteTextView as well. Hope it works for you:)

Works for me. If you trying EditText with Label and trying change to underline color use this. Change to TextInputEditText instead EditText.
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/editTextTextPersonName3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="#dimen/_16sdp"
android:layout_marginLeft="#dimen/_16sdp"
android:layout_marginTop="#dimen/_16sdp"
android:layout_marginEnd="#dimen/_8sdp"
android:layout_marginRight="#dimen/_8sdp"
android:textColorHint="#color/white"
app:layout_constraintEnd_toStartOf="#+id/guideline3"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:backgroundTint="#color/white"
android:hint="Lastname"
android:textSize="#dimen/_14sdp"
android:inputType="textPersonName"
android:textColor="#color/white"
android:textColorHint="#color/white" />
</com.google.android.material.textfield.TextInputLayout>

Change line color of TextInputLayout + TextInputEditText
colors.xml
<color name="mtrl_textinput_default_box_stroke_color" tools:override="true">#color/lineColor</color>
styles.xml
<style name="TextInputLayout" parent="Widget.MaterialComponents.TextInputLayout.FilledBox.Dense">
<item name="boxStrokeColor">#color/lineColor</item>
<item name="android:textColorHint">#color/hintColor</item>
<item name="boxStrokeWidth">1dp</item>
<item name="boxBackgroundColor">#color/backgroundColor</item>
</style>
<style name="TextInputEditText" parent="ThemeOverlay.MaterialComponents.TextInputEditText.FilledBox.Dense">
<item name="android:textColor">#color/black</item>
</style>
layout.xml
<com.google.android.material.textfield.TextInputLayout
style="#style/TextInputLayout"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<com.google.android.material.textfield.TextInputEditText
style="#style/TextInputEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text" />
</com.google.android.material.textfield.TextInputLayout>

You can change the label color of TextInputLayout by using app:hintTextAppearance attribute in TextInputLayout.
<android.support.design.widget.TextInputLayout
android:id="#+id/inputlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintTextAppearance="#style/TextAppearance.App.TextInputLayout">
<EditText
android:id="#+id/mail"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:hint="#string/email"
android:inputType="textEmailAddress"
android:maxLines="1"
android:paddingStart="5dp"
android:singleLine="true"/>
</android.support.design.widget.TextInputLayout>
Style:
<style name="TextAppearance.App.TextInputLayout"
parent="#android:style/TextAppearance">
<item name="android:textColor">#android:color/black</item>
<item name="android:textSize">20sp</item>
</style>
To change edittext underline color, you can use android:backgroundTint
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Underline color change"
android:backgroundTint="#android:color/holo_red_light" />

Create style as mentioned below
<style name="text_input_layout_style">
<item name="colorControlNormal">#color/primary</item>
<item name="colorControlActivated">#color/primary</item>
<item name="colorControlHighlight">#color/primary</item>
</style>
and apply it to your TextInputLayout as android:theme="#style/text_input_layout_style"
And definitely will work for you all.

I needed to change the bottom line color of a TextInputEditText inside a TextInputLayout and then the other answers didn't work out. I finally solved it by setting the colorOnSurface for the TextInputLayouts theme. I'll leave my code here in case it helps someone else.
XML:
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:theme=""#style/TextInputLayoutStyle"">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</com.google.android.material.te`tfield.TextInputLayout>
Style:
<style name="TextInputLayoutStyle">
<item name="colorOnSurface">#0ff</item>
</style>

XML
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/activity_profile_textInputLayout_mobile"
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginTop="10dp"
android:layout_marginRight="20dp"
android:hint="Mobile Number"
app:theme="#style/EditBoxColor">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/activity_profile_textInputEditText_mobile"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:imeOptions="actionNext"
android:inputType="number"
android:maxLength="10"
android:textSize="15sp" />
</com.google.android.material.textfield.TextInputLayout>
Style
<style name="EditBoxColor" parent="ShapeAppearance.MaterialComponents.SmallComponent">
<item name="colorPrimary">#color/colorPurple</item>
<item name="colorPrimaryDark">#color/colorPurple3</item>
</style>
