How to change inactive border stroke color of Android Material TextInputLayout component

Question

I am trying to setting up TextInputLayout unfocused border stroke color. For the same, There are too many questions and their answers and I have tried all of them. Like Created styles and used as theme, Created color selector and applied that, and also applied directly app:boxStrokeColor with color selector. But not luck with any of these available solutions.

Not sure, where do i am doing wrong or something i still missing. I pushed my code to Test project to github for to get better visibility of my whole setup. Here is some sample code for quick review:

activity_main.xml (TextInputLayout inside ConstraintLayout)

<com.google.android.material.appbar.MaterialToolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <!-- Tried this as well - app:boxStrokeColor="@color/text_input_box_stroke_color" -->
    <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/emailTextInputLayout"
        android:hint="Email"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="24dp"
        android:theme="@style/TextInputLayoutStyle"
        android:layout_marginHorizontal="24dp"
        app:layout_constraintTop_toBottomOf="@id/toolbar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/emailTextInput"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:importantForAutofill="no"
            android:inputType="textEmailAddress" />

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

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense">
        <item name="boxStrokeColor">#FF00CC</item>
        <item name="boxStrokeWidth">2dp</item>
    </style>
</resources>

text_input_box_stroke_color.xml (color selector)

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/mtrl_textinput_focused_box_stroke_color" android:state_focused="true"/>
    <item android:color="@color/mtrl_textinput_hovered_box_stroke_color" android:state_hovered="true"/>
    <item android:color="@color/mtrl_textinput_disabled_color" android:state_enabled="false"/>
    <item android:color="@color/mtrl_textinput_default_box_stroke_color"/>
</selector>

It would be great help if someone can provide some guideline and suggestion and help me figure out any mistake made by me.

Thanks in advance.

Solution for this is next, and this works because I JUST NOW tested it.

Go to your colors.xml inside your res>values folder.

In there you'll have your colorPrimary and other colors you already created before. Scroll to the bottom and add this line:

<color name="mtrl_textinput_default_box_stroke_color" tools:override="true">@color/colorPrimary</color>

When you do that, you can just change the color there. I defined as @color/colorPrimary but you can use whatever you want. Before applying this line I got this:

And after applying that line this is the result:

Also I applied style="@style/YourStyle" for both TextInputLayout and TextInputEditText

I have tested your code and it works after you do the below changes:

1.First change your res/color/text_input_box_stroke_color.xml like below to see the different states colors. In the below example i have set a Red color for the focused state and a Light Blue color for default-inactive state:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@android:color/holo_red_dark" android:state_focused="true" />
    <item android:color="@android:color/holo_green_dark" android:state_hovered="true" />
    <item android:color="@color/mtrl_textinput_disabled_color" android:state_enabled="false" />
    <item android:color="@android:color/holo_blue_light" />
</selector>

2.Then change your res/values/styles.xml with the boxStrokeColor linking to the above selector like below:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense">
        <item name="boxStrokeColor">@color/text_input_box_stroke_color</item>
        <item name="boxStrokeWidth">2dp</item>
    </style>
</resources>

3.Finally in your TextInputLayout add this style like below:

<com.google.android.material.textfield.TextInputLayout
    style="@style/TextInputLayoutStyle"
    android:id="@+id/emailTextInputLayout"

Currently your adding the style like: android:theme="@style/TextInputLayoutStyle" instead of style="@style/TextInputLayoutStyle"

Answer 3

Create a box stroke color for active and inactive state like below: box_stroke_color

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="#2C2C2C" android:state_focused="true"/>
    <item android:color="#2C2C2C" android:state_hovered="true"/>
    <item android:color="#D7D7D7"/>
</selector>

Make a TextInputLayout style : TextInputLayoutStyle

 <style name="TextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
        <item name="boxStrokeColor">@color/box_stroke_color</item>
        <item name="boxStrokeWidth">1dp</item>
    </style>

Use in your TextInputLayout

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