在ListPreference中以编程方式设置默认值

Question

I'm trying to set the default value of a ListPreference programmatically, but it has no effect. I am inflating the preference from xml, and then setting the values dynamically.

addPreferencesFromResource(R.xml.pref_general);
ListPreference sizePreference = findPreference("picture_size");
sizePreference.setEntries(entries);
sizePreference.setEntryValues(entryValues);
sizePreference.setDefaultValue(entryValues[0]);

bindPreferenceSummaryToValue(sizePreference);

Is there a way to do this without having to override Preference ?

Answer 1

尝试这个：

setValueIndex(int index);

Answer 2

你试过setValueIndex（int index）吗？

sizePreference.setValueIndex(0);
