I'm trying to change default switch thumb in preference screen to my custom. I've tried different solutions found here but none of them working. My last try was to create a custom layout but the problem is that I can't properly add switch to that layout. Can't really add androidx.appcompat.widget.SwitchCompat because of the id (@android:id/switch_widget requires API level 24 (current min is 21) or with other suggested id: Cannot resolve symbol '@android:id/switchWidget'). root_preferences.xml (part):
<PreferenceCategory app:title="@string/confidentiality"
android:layout="@layout/preferences_category">
<SwitchPreferenceCompat
android:layout="@layout/switch_preference_compat"
app:key="show_contacts"
app:title="@string/contact_information"
app:singleLineTitle="false"
app:defaultValue="true"
app:iconSpaceReserved="false"/>
</PreferenceCategory>
switch_preference_compat.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:orientation="vertical">
<TextView
android:id="@android:id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/ks_font_data"
android:textSize="18sp"/>
<TextView
android:id="@android:id/summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"/>
</LinearLayout>
<androidx.appcompat.widget.SwitchCompat
android:id="@android:id/switchWidget" <--- error here
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
I tried styles but it also didn't work well. I want my thumb looks like this[my custom switch][1] [1]: https://i.sstatic.net/Js5vb.png
So after a few hours I was able to find out how to do that. Posting this answer so it may help somebody save their time. In root_preferences.xml there is android:widgetLayout property where you can set custom layout for SwitchPreferenceCompat:
<SwitchPreferenceCompat
android:widgetLayout="@layout/switch_preference_compat"
app:key="show_contacts"
app:title="@string/contact_information"
app:singleLineTitle="false"
app:defaultValue="true"
app:iconSpaceReserved="false"/>
switch_preference_compat.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
android:gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:orientation="vertical">
<TextView
android:id="@android:id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"/>
<TextView
android:id="@android:id/summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"/>
</LinearLayout>
<androidx.appcompat.widget.SwitchCompat
android:id="@+id/switchWidget"
android:thumb="@drawable/thumb"
app:track="@drawable/track"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
there is where you put your drawables for custom thumb and track. Mine looks so: thumb.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false"
android:drawable="@drawable/switch_icon_false" />
<item android:state_checked="true"
android:drawable="@drawable/switch_icon_true"/>
</selector>
track.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false">
<shape android:shape="rectangle">
<solid android:color="#dedede"/>
<corners android:radius="100sp"/>
<stroke android:color="#dedede"
android:width="1dp"/>
</shape>
</item>
<item android:state_checked="true">
<shape android:shape="rectangle">
<solid android:color="#9dcbb5"/>
<corners android:radius="100sp"/>
</shape>
</item>
</selector>
