XML attributes

android:disableDependentsState

The state (true for on, or false for off) that causes dependents to be disabled. By default, dependents will be disabled when this is unchecked, so the value of this preference is false.

May be a boolean value, such as "true" or "false".

android:summaryOff

The summary for the Preference in a PreferenceActivity screen when the SwitchPreference is unchecked. If separate on/off summaries are not needed, the summary attribute can be used instead.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:summaryOn

The summary for the Preference in a PreferenceActivity screen when the SwitchPreference is checked. If separate on/off summaries are not needed, the summary attribute can be used instead.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:switchTextOff

The text used on the switch itself when in the "off" state. This should be a very SHORT string, as it appears in a small space.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:switchTextOn

The text used on the switch itself when in the "on" state. This should be a very SHORT string, as it appears in a small space.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;
