Unable to change switch color

Question

I'm looking for applying this color to all switches only. But by default, it is taking colorAccent instead of this theme for switch.

Device: marshmallow.

layout:

<Switch
            android:id="@+id/soundSwitch"
            style="@style/SwitchStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_centerVertical="true"
            android:layout_marginBottom="@dimen/large_space"
            android:layout_marginRight="@dimen/medium_space"
            android:layout_marginTop="@dimen/large_space"
            android:checked="true"
            />

styles-v21:

<style name="SwitchStyle" parent="Theme.AppCompat.Light">
        <!-- active thumb & track color (30% transparency) -->
        <item name="android:colorControlActivated">@color/switch_color</item>

        <!-- inactive thumb color -->
        <item name="colorSwitchThumbNormal">#f1f1f1</item>

        <!-- inactive track color (30% transparency) -->
        <item name="android:colorForeground">#42221f1f</item>
    </style>

What am I doing wrong?

Answer 1

You're mixing styles and themes together.

These attributes are theme attributes so define them together in a theme overlay:

res/values/styles.xml (not values-v21)

<style name="ThemeOverlay.MySwitch" parent="">
    <item name="android:colorControlActivated">@color/switch_color</item>
    <item name="android:colorSwitchThumbNormal">#f1f1f1</item>
    <item name="android:colorForeground">#42221f1f</item>
</style>

<style name="ThemeOverlay.MySwitchCompat" parent="">
    <item name="colorControlActivated">@color/switch_color</item>
    <item name="colorSwitchThumbNormal">#f1f1f1</item>
    <item name="android:colorForeground">#42221f1f</item>
</style>

And then apply this theme overlay on the switch:

res/layout/layout.xml

<Switch
    android:theme="@style/ThemeOverlay.MySwitch"/>

<androidx.appcompat.widget.SwitchCompat
    android:theme="@style/ThemeOverlay.MySwitchCompat"/>

Pick one of the two variants:

• Switch available since API 21, all theme attributes are prefixed with android:
• SwitchCompat available in AndroidX AppCompat library, some theme attributes are not prefixed (make sure you know which).
