Hi all,
i need to set the defult value for a ListPreference when the Activity
starts.
I've tried with `ListPreference.setDefaultvalue("value");` but it
makes the firts Entry of the List as default. I need it because i must
check a condition and set as default the value which satisfies that
condition, so I think it can't be done from the xml file (with
`android:defaultValue`)
For example, suppose I have this array of values in the arrays.xml:
<string-array name="opts">
<item>red</item>
<item>green</item>
<item>blue</item>
</string-array>
<string-array name="opts_values">
<item>1</item>
<item>2</item>
<item>3</item>
</string-array>
In the PreferenceScreen xml:
<ListPreference
android:title="Colour select"
android:summary="Select your favourite"
android:key="colour"
android:entries="@array/opts"
android:entryValues="@array/opts_values" />
In the Activity I'd like to do something like this:
String mycolour;
if (something)
mycolour="1";
else
mycolour="2";
ListPreference colour=(ListPreference) findPreference ("colour");
colour.setDefaultValue(mycolour);
But it doesn't work, because it makes the first choice as default.
Could you explain me how to make another one as default? Thanks.
