Issue: change border color or box stroke for unfocused TextInputLayout in android

问题

I have a very specific issue for changing the outline of the textbox for TextInputLayout when it's unfocused. I can't seem to find an attribute to change the color for the border of my "unfocused" text box.

Here's a visual example of what I'm trying to do:

The color of this (textbox):border is not white. currently its not focused. After I click it, it turns white:

I don't know what I need to change, it doesn't seem like there is an attribute to change it.

I'm also using material design text input layout styles, although I don't see if that will affect it.

Here is my xml code for the text box:

 <other layouts ... >
     <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="70dp"
            android:layout_gravity="bottom"
            android:layout_margin="5dp"
            android:background="@drawable/item_recycler_view">

            <android.support.design.widget.TextInputLayout
                android:id="@+id/dialog_text_input_layout"
                style="@style/Widget.AppTheme.TextInputLayoutList"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Quick Add..."
                android:textColorHint="@color/colorWhite"
                app:boxStrokeColor="@color/colorWhite"
                app:errorEnabled="true"
                >

                <android.support.design.widget.TextInputEditText
                    android:id="@+id/dialog_edit_text"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:inputType="text"
                    android:maxLines="1"
                    android:textColor="@color/colorWhite"
                    android:textSize="14sp" />
            </android.support.design.widget.TextInputLayout>
        </RelativeLayout>
 </other layouts...>

And here are the styles that I use for this:

<style name="TextAppearance.AppTheme.TextInputLayout.HintTextAlt" parent="TextAppearance.MaterialComponents.Subtitle2">
    <item name="android:textColor">@color/colorWhite</item>
</style>

<style name="Widget.AppTheme.TextInputLayoutList" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
    <item name="hintTextAppearance">@style/TextAppearance.AppTheme.TextInputLayout.HintTextAlt</item>
    <item name="boxStrokeColor">@color/colorWhite</item>
    <item name="boxCornerRadiusBottomEnd">5dp</item>
    <item name="boxCornerRadiusBottomStart">5dp</item>
    <item name="boxCornerRadiusTopEnd">5dp</item>
    <item name="boxCornerRadiusTopStart">5dp</item>
    <item name="android:layout_margin">5dp</item>
</style>

Thanks, any help or suggestions are welcome!

If you want to set the color for the outline box in unfocused mode instead of the default black, you have to add this line in colors.xml file which will override the default color for the outline box.

copy this line as it is. you can change color to what you want.

<color name="mtrl_textinput_default_box_stroke_color">#fff</color>

until now it will work, for more control on TextInputLayout you may add this style in styles.xml

<style name="TextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense">
    <item name="boxStrokeColor">#fff</item>
    <item name="boxStrokeWidth">2dp</item>
</style>

then add theme to TextInputLayout

android:theme="@style/TextInputLayoutStyle"

With the Material Components Library just use the boxStrokeColor attribute.
It can work with a selector.

Just use something like:

    <com.google.android.material.textfield.TextInputLayout
        app:boxStrokeColor="@color/text_input_layout_stroke_color"
        ..>

with:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:alpha="..." android:color="@color/...." android:state_focused="true"/>
  <item android:alpha="..." android:color="@color/...." android:state_hovered="true"/>
  <item android:alpha="..." android:color="@color/...." android:state_enabled="false"/>
  <item android:alpha="..." android:color="@color/...."/>  <!-- unfocused -->
</selector>

Answer from Amjad was right, but starting from 1.1.0-alpha02 (probably even alpha01) after this issue was resolved it's possible to define color in color state list using the same boxStrokeColor attribute, e.g. how it's done in lib:

<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>
