readme.xml

style.xml 파일에서

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.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="progressBarStyle" parent="@style/Widget.AppCompat.ProgressBar.Horizontal">
        <item name="android:indeterminateDrawable">@drawable/progress_bar_drawable</item>
    </style>
</resources>



/res/drawable/progress_bar_drawable.xml  하나만들고

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape>
            <solid android:color="@color/colorPrimary"/>
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <solid android:color="@color/colorPrimaryDark"/>
            </shape>
        </clip>
    </item>
</layer-list>
