You'll notice that even if you put android:numeric="integer", the
setting will be saved and loaded as a string.
If you want it to be a integer:
package com.ubikod.android.ubikim.settings;
import android.content.Context;
import android.preference.EditTextPreference;
import android.util.AttributeSet;
public class EditIntegerPreference extends EditTextPreference
{
public EditIntegerPreference(Context context)
{
super(context);
}
public EditIntegerPreference(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public EditIntegerPreference(Context context, AttributeSet attrs,
int defStyle)
{
super(context, attrs, defStyle);
}
@Override
public String getText()
{
return String.valueOf(getSharedPreferences().getInt(getKey(), 0));
}
@Override
public void setText(String text)
{
getSharedPreferences().edit().putInt(getKey(),
Integer.parseInt(text))
.commit();
}
}
and use <com.ubikod.android.ubikim.settings.EditIntegerPreference
instead of <EditTextPreference in the XML
