Why am I getting a ClassCastException here?
- by Holly
I'm creating an android application and i'm trying to use a PreferenceActivity.
I'm getting the java.lang.ClassCastException: java.lang.String error when it gets to this line return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_TERM, USER_TERM_DEF);
I thought it might be because I'm not converting it properly from it's string value in the EditText box to the int I need but I can't figure out how to fix this, or is that even the cause? I'm flummoxed.
Here's my preference activity class:
public class UserPrefs extends PreferenceActivity {
//option names and default vals
private static final String USER_TERM = "term_length";
private static final String USER_YEAR = "year_length";
private static final int USER_TERM_DEF = 12;
private static final int USER_YEAR_DEF = 34;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
public static int getTermLength(Context context){
try{
return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_TERM, USER_TERM_DEF);
}catch (ClassCastException e){Log.v("getTermLength", "error::: " + e); }
//return 1;//temporary, needed to catch the error and couldn't without adding a return outside the block.//
}
public static int getYearLength(Context context){
return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_YEAR, USER_YEAR_DEF);
}
And here's the bit of code where I'm trying to use the the preferences inside another class:
public float alterForFrequency(Context keypadContext, float enteredAmount, String spinnerPosition){
int termLength = UserPrefs.getTermLength(keypadContext);
int yearLength = UserPrefs.getYearLength(keypadContext);
}
