Since the appcompat v7 is missing a SwitchCompatPreference
it seems like it's necessary to create it by myself.
How can this be achieved? I googled a bit and found a tutorial for a DialogPreference
. I tried to adopt it for a SwitchCompatPreference
but in my xml layout it always says that this class is not allowed in the preference xml.
What do I need to do?
You do not need to create a new component.
First of all, you should use CheckBoxPreference
instead of SwitchPreference, in order to support lower APIs.
Using the existing android.support.v7.widget.SwitchCompat
widget, create a new layout file, for example l_switch.xml
. Use the following code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SwitchCompat xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/checkbox" <!-- IMPORTANT -->
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@null"
android:clickable="false" <!-- IMPORTANT -->
android:focusable="false" <!-- IMPORTANT -->
android:gravity="center" />
Then, to your SwitchPreference CheckBoxPreference in PreferenceFragment
,
yourSwitch = findPreference("key_for_this_component");
yourSwitch.setWidgetLayoutResource(R.layout.l_switch);
or, to your CheckBoxPreference directly,
android:widgetLayout="@layout/l_switch"
This will force the CheckBoxPreference to use the SwitchCompat
style.
