MAX and MIN AND INTERVAL BUG

[Missyouag]

I find some problem,and I think...
In com.pavelsikun.seekbarpreference PreferenceControllerDelegate

1. preferencevalue not change;

2. INTERVAL bug

a lot...

is My com.pavelsikun.seekbarpreference PreferenceControllerDelegate:

package com.pavelsikun.seekbarpreference;

import android.content.Context;
import android.content.res.TypedArray;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import android.widget.SeekBar;
import android.widget.TextView;
