How to remove the outline from AutoCompleteTextView?

I have a layout with several TextInputEditText fields nested in TextInputLayouts. I also have one dropdown menu using AutoCompleteTextView, also nested in a TextInputLayout. I use a custom background drawable on the fields to create a rounded field. Unfortunately, I cannot for the life of me figure out how to get rid of the little outline around the AutoCompleteTextView.
With the TextInputEditText fields, I can eliminate the outlines by setting the background on it. Doing this on the AutoCompleteTextView does nothing, and I have to set it on the parent TextInputLayout to see the background. But yet, the outline remains.
I believe this has something to do with material design (and its styles?) because when you press on the field, the outline turns orange, which is the primary color in our app's theme as set in the styles.xml.
Here is a relevant snippet of the XML layout in question. For comparison, the first part is the city field, and the second is the state field:
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/input_city"
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:visibility="#{viewModel.addDevice.isFinishedWithSettings ? View.INVISIBLE : View.VISIBLE}"
app:endIconMode="clear_text"
app:hintEnabled="false"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/input_apartment">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/input_city_edit_text"
style="#style/AppFont500.DarkGrey.EditTextHint"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingStart="25dp"
android:paddingEnd="25dp"
android:paddingLeft="25dp"
android:paddingRight="25dp"
android:visibility="#{viewModel.addDevice.isFinishedWithSettings ? View.INVISIBLE : View.VISIBLE}"
android:imeOptions="actionDone"
android:inputType="number"
android:text="#={viewModel.addDevice.city}"
android:hint="#string/hint_city"
android:background="#drawable/rounded_edittext_states"
/>
</com.google.android.material.textfield.TextInputLayout>
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/input_state"
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:visibility="#{viewModel.addDevice.isFinishedWithSettings ? View.INVISIBLE : View.VISIBLE}"
app:endIconMode="dropdown_menu"
app:hintEnabled="false"
app:layout_constraintEnd_toStartOf="#id/input_zip_code"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/input_city"
android:background="#drawable/rounded_edittext_states"
>
<AutoCompleteTextView
android:id="#+id/input_state_edit_text"
style="#style/AppFont500.DarkGrey.EditTextHint"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingStart="25dp"
android:paddingEnd="25dp"
android:paddingLeft="25dp"
android:paddingRight="25dp"
android:layout_marginEnd="4dp"
android:visibility="#{viewModel.addDevice.isFinishedWithSettings ? View.INVISIBLE : View.VISIBLE}"
android:imeOptions="actionDone"
android:inputType="none"
android:text="#={viewModel.addDevice.state}"
android:hint="#string/hint_state"
/>
</com.google.android.material.textfield.TextInputLayout>
I believe the key here involves styles and themes. Here are the custom styles and theme used within this snippet:
<style name="AppMaterialTheme" parent="#style/Theme.MaterialComponents.Light.NoActionBar">
<item name="colorPrimary">#color/primaryOrange</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
</style>
<style name="AppFont500">
<item name="fontFamily">#font/poppins_medium_500</item>
</style>
<style name="AppFont500.DarkGrey">
<item name="android:textColor">#color/secondaryDarkGrey</item>
</style>
<style name="AppFont500.DarkGrey.EditTextHint">
<item name="android:textSize">16sp</item>
</style>
The background comes from this selector. It previously had more items, but right now just has one:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="true"
android:drawable="#drawable/rounded_edittext" />
</selector>
And the drawable:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:padding="10dp">
<solid android:color="#FFFFFF" />
<corners
android:radius="30dp" />
</shape>
Mainly, what I have seen in questions related to outlines around edit texts is to either edit the stroke or boxStroke. I tried both and set them to an invisible value, but it does not change the stroke at all.

Here is how you remove this outline.
In your TextInputLayout XML code add the following snippet:
app:boxStrokeWidth="0dp"

How to remove underline from dropdown menu material design in android

I can't seem to get rid of the black underline from Exposed Dropdown Menu done according to material design guide in my android UI.
The dropdown looks like this:
I have tried setting background to null, transparent or custom shape. app:boxBackgroundMode="none" doesn't work either.
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/spinner_age"
style="#style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg_rounded_button"
android:hint="Age">
<AutoCompleteTextView
android:id="#+id/age_dropdown"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"/>
</com.google.android.material.textfield.TextInputLayout>
Ideally the dropdown would look like a button without the underline. How do I get rid of it?

Please change your this line
android:background="#android:color/transparent"
With
android:background="#00000000"

Make background = null
<AutoCompleteTextView
android:id="#+id/age_dropdown"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"/>

just add this line to remove the underline
android:inputType="textNoSuggestions"

Just use the standard style #style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu and
You don't need to use a custom background shape, you can just use the
app:boxCornerRadius* attributes to define the rounded shape.
Something like:
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
app:boxCornerRadiusBottomEnd="32dp"
app:boxCornerRadiusTopEnd="32dp"
app:boxCornerRadiusBottomStart="32dp"
app:boxCornerRadiusTopStart="32dp"
app:boxStrokeColor="#color/myselector"
...>
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
/>
</com.google.android.material.textfield.TextInputLayout>
To change the color of the line under the component, you have to change the app:boxStrokeColor attribute. Just customize the selector as you prefer:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:alpha="0" android:color="?attr/colorOnSurface" android:state_hovered="true"/>
<item android:alpha="0" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
<item android:alpha="0" android:color="?attr/colorOnSurface"/>
</selector>
This is the result:
Pay attention to this note in doc:
Note: When using a filled text field with an EditText child that is not a TextInputEditText, make sure to set the EditText's android:background to #null. This allows TextInputLayout to set a filled background on the EditText.
Alternative:
With the new version 1.1.0 you can also use the shapeAppearanceOverlay attribute to customize the shape of your component.
Just use:
<com.google.android.material.textfield.TextInputLayout
style="#style/MyFilledBox_ExposedDropdownMenu
...>
<AutoCompleteTextView
android:background="#null"
... />
</com.google.android.material.textfield.TextInputLayout>
and this style:
<!-- Rounded -->
<style name="MyFilledBox_ExposedDropdownMenu" parent="#style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu">
<item name="shapeAppearanceOverlay">#style/ShapeAppearanceOverlay.MyApp.TextInputLayout.Rounded</item>
<item name="boxStrokeColor">#color/myselector</item>
</style>
<style name="ShapeAppearanceOverlay.MyApp.TextInputLayout.Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">32dp</item>
</style>

Setting boxStrokeWidth = 0dp would solve it

TextInputLayout hint color in error state

As per Googles Material Guidelines:
https://material.io/guidelines/components/text-fields.html#text-fields-layout
TextInputLayout hint should be the same color as the Error message:
However it is not like that and when I call setError("My error") only the underline and the error message show up in red.
How can I change this behavior to account for Google's own guidelines?

Here is how you can do it:
<android.support.design.widget.TextInputLayout
android:padding="8dp"
android:id="#+id/tilSample"
app:errorTextAppearance="#style/error_appearance"
app:hintTextAppearance="#style/error_appearance"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/etSample"
android:layout_margin="8dp"
android:padding="8dp"
android:hint="android"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.TextInputLayout>
style.xml
<style name="error_appearance" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/colorRed</item>
<item name="android:textSize">12sp</item>
</style>
colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#FF4081</color>
<color name="colorRed">#f44336</color>
</resources>
EDIT
We can manipulate the error and hint colours in code also using:
tilSample.setErrorTextAppearance(R.style.error_appearance);
tilSample.setHintTextAppearance(R.style.error_appearance);

Now this is default behaviour. To achieve this, just update your support library version to 28+.
implementation 'com.android.support:design:28.0.0'

We can manipulate the error as helper text because if you set an error it will definitely change the hint color, so I just used helperText instead of setError, here is an example

<com.google.android.material.textfield.TextInputLayout
android:id="#+id/textInputLayoutUserName"

Function
fun TextInputLayout.setErrorText(error : String, editText: EditText) {
this.helperText = error
editText.backgroundTintList = ColorStateList.valueOf(
ResourcesCompat.getColor(resources,
R.color.colorNegative, null)
)
}

Here is another method which you may would try
fun wrapInCustomStyle(myText: String): Spannable? {
val spannable = SpannableString(myText) Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
//Test 'Alignment.ALIGN_OPPOSIT' Too if not working
spannable.setSpan(
AlignmentSpan.Standard(Layout.Alignment.ALIGN_NORMAL), 0,
myText.length, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
return spannable
}
InputLayout.error=wrapInCustomStyle("sample")

You can use the "helperTextTextColor" attribute to do this.
<com.google.android.material.textfield.TextInputLayout
app:hintTextColor="#color/color_login_text_hint"
app:helperTextTextColor="#color/error_color">
</com.google.android.material.textfield.TextInputLayout>

Here is an example:

android:layout_height="wrap_content"
android:id="#+id/email_layout"
android:textColorHint="#color/gray"
app:errorTextAppearance="#style/TextAppearence.App.TextInputLayout"
app:hintTextAppearance="#style/TextAppearence.App.TextInputLayout">

How to fix missing styles when using theme in TextInputLayout

I use the TextInputLayout widget for custom EditText.
<android.support.design.widget.TextInputLayout
android:theme="#style/EditTextHint"
android:id="#+id/panelID"
android:paddingTop="30dp"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/txtID"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Engage code here"
android:inputType="textCapWords"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:maxLines="1"
tools:ignore="HardcodedText" />
</android.support.design.widget.TextInputLayout>
With style :
<style name="EditTextHint" parent="TextAppearance.AppCompat">
<item name="colorAccent">#DD4B39</item>
<item name="android:textColorHint">#DD4B39</item>
<item name="colorControlNormal">#545454</item>
<item name="colorControlActivated">#545454</item>
<item name="colorControlHighlight">#545454</item>
</style>
To get some custom EditText. But I found some error
When I ignore the error, and still run my application there is no error, just a warning on the design panel in android studio
What should I add in the style that the error could be disappear?
Thanks

your parent should be #android:style/TextAppearance instead of TextAppearance.AppCompat

You can try to use another nameSpace for attribute colorControlHighlight
Try this:
xmlns:app="http://schemas.android.com/apk/res-auto"
instead this
xmlns:android="http://schemas.android.com/apk/res/android"

How to change the hint size of TextInputLayout

This is my xml
<android.support.design.widget.TextInputLayout
style="#style/main_input_text"
android:layout_marginTop="#dimen/activity_medium_margin"
app:hintTextAppearance="#style/TextAppearence.App.TextInputLayout">
<android.support.v7.widget.AppCompatEditText
style="#style/main_edit_text"
android:inputType="text" />
</android.support.design.widget.TextInputLayout>
And this is style
<style name="main_input_text">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">#dimen/activity_edittext_height</item>
<item name="android:background">#drawable/mc_shape_border_button_transparent</item>
<item name="android:gravity">center_vertical</item>
<item name="android:paddingTop">#dimen/activity_extra_small_margin</item>
<item name="android:paddingBottom">#dimen/activity_extra_small_margin</item>
<item name="android:keyTextSize">8sp</item>
<item name="android:textSize">8sp</item>
</style>
I don't find something like hintSize, textSize and keyTextSize not helping

In your styles.xml
<style name="TextLabel" parent="TextAppearance.Design.Hint">
<item name="android:textSize">16sp</item>
</style>
And then in your layout file:
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/activity_horizontal_margin"
android:layout_marginRight="#dimen/activity_horizontal_margin"
android:layout_marginTop="12dp"
app:hintTextAppearance="#style/TextLabel"
android:minHeight="30dp">

Change the TextInputLayout's app:errorTextAppearance in XML.
<android.support.design.widget.TextInputLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:errorTextAppearance="#style/CustomTextInputLayoutStyle.ErrorTextStyle">
Where CustomTextInputLayoutStyle.ErrorTextStyle is defined in styles.xml as
<style name="CustomTextInputLayoutStyle.ErrorTextStyle" parent="TextAppearance.Design.Error">
<item name="android:textSize">10sp</item>
</style>

#Santiago Martínez answer only works for hints on non empty Edittext (inside TextInputLayout)
But for empty Edittext, TextInputLayout hint takes property from Edittext textSize.

1) Add hintTextAppearance to your InputLayout with a style
<android.support.design.widget.TextInputLayout xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintTextAppearance="#style/TextInputLayoutHintText" >
<android.support.design.widget.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="16sp" />
</android.support.design.widget.TextInputLayout>
2) Then just add the style to your styles.xml
<style name="TextInputLayoutHintText">
<item name="android:textColor">#color/gray</item>
<item name="android:textSize">12sp</item></style>

For material 1.4.0
implementation 'com.google.android.material:material:1.4.0'
You only need to change the android:textSize attribute for the TextInputEditText for the hint size to change.
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
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:textSize="18sp"/>
</com.google.android.material.textfield.TextInputLayout>

You can reduce the font size on the EditText - that will reduce the size of the hint as well. i.e. android:textSize="16sp"
