问题描述
每隔preference我有触发其在preferenceChangeListener。然而,我的铃声preference它不会:
P =获取preferenceScreen()找到preference(pref_tone);
串RNAME = preferences.getString(pref_tone,Settings.System.DEFAULT_RINGTONE_URI.toString());
字符串名称= ringtoneToName(RNAME);
p.setSummary(名称);
p.setOn preferenceChangeListener(新在preferenceChangeListener(){
在preferenceChange公共布尔(preference preference,对象为newValue){
//永远不要打了!
串V =(字符串类型)newValue;
preference.setSummary(ringtoneToName(ⅴ));
返回true;
}
});
解决方案
onActivityResult只好打电话super.onActivityResult是修复
Every other preference I have fires its OnPreferenceChangeListener. However, my RingtonePreference it doesn't:
p = getPreferenceScreen().findPreference("pref_tone");
String rname = preferences.getString("pref_tone",Settings.System.DEFAULT_RINGTONE_URI.toString());
String name = ringtoneToName(rname);
p.setSummary(name);
p.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
// Never hits here!
String v = (String) newValue;
preference.setSummary(ringtoneToName(v));
return true;
}
});
解决方案
onActivityResult had to call super.onActivityResult is the fix
