android.preference.ListPreference.getSummary(ListPreference.java)
It happens only on Cyanogen's firmware when there's "%" symbol in
ListPreference's summary.
If u will open ListPreference.java from Froyo's sources u wouldn't
find method ListPreference.getSummary, so it looks like ListPreference
uses base method from Preference.java:
public CharSequence getSummary() {
return mSummary;
}
And javadoc's from eclipse it confirms that:Returns the summary of
this Preference.
Ok, now let's open ListPreference.java from Cyanogen's sources:
public CharSequence getSummary() {
final CharSequence entry = getEntry();
if (mSummary == null || entry == null) {
return super.getSummary();
} else {
return String.format(mSummary, entry);
}
}
It look's like it's Cyanogen's feature (only 8 bug reports from >3000
users), but let's go to
http://developer.android.com/reference/android/preference/ListPreference.html:
Returns the summary of this ListPreference. If the summary has a
String formatting marker in it (i.e. "%s" or "%1$s"), then the current
entry value will be substituted in its place.
WHAT IS GOING ON HERE???
Can someone explain how *exactly* getSummary works?
