I have an XML file called user_preferences that contains my
preferences for my application.
How do I get hold of the different preference Views so that I can
validate them?
Currently I have the code below which is not working because
getSharedPreferences does not return a View.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.user_preferences);
//get a handle on preferences that require validation
timeLimitPreference = (EditTextPreference)
this.getSharedPreferences
("time_limit", MODE_PRIVATE);
timeLimitPreference.setOnPreferenceChangeListener(new
OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference
preference, Object
newValue) {
//Check that the string is an integer.
if( newValue.toString()!=null &&
newValue.toString().matches("\\d
{1-5}") ) {
Log.e(TAG, "Not a number");
newValue = 30;
return true;
}
Log.e(TAG, "Is a number");
return false;
}
});
}
