Android5.0里面的AbsSeekBar重写后无法触发onProgressChanged事件

[coder_master]

我有一个应用需要用到垂直的Seekbar，所以在现有的AbsSeekBar基础上重写了，代码借鉴了现在网上到处都找得到的例子。原先在Android5.0以下的系统运行正常，手机升级到5.0之后，就出问题了，滑动Seekbar的时候，只能触发onStartTrackingTouch和onStopTrackingTouch这两个事件，onProgressChanged无法触发，在上层我就无法获取到这个Seekbar的值了。
请问大伙有遇到过这个情况吗？Android5.0是否对onProgressChanged这个函数做了改动？
附上代码如下：

package com.pulque;

调用：

package com.pulque;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class VerticalSeekbarActivity extends Activity {
    /** Called when the activity is first created. */
	private com.pulque.SeekBar mb;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mb=(com.pulque.SeekBar )findViewById(R.id.seekbar);
        mb.setOnSeekBarChangeListener(new com.pulque.SeekBar.OnSeekBarChangeListener(){

			@Override
			public void onProgressChanged(com.pulque.SeekBar VerticalSeekBar,
					int progress, boolean fromUser) {
				// TODO Auto-generated method stub
				Log.d("VerticalSeekbarActivity-----------",""+progress);
			}

			@Override
			public void onStartTrackingTouch(com.pulque.SeekBar VerticalSeekBar) {
				// TODO Auto-generated method stub
				Log.d("VerticalSeekbarActivity","onStartTrackingTouch-----------");
			}

			@Override
			public void onStopTrackingTouch(com.pulque.SeekBar VerticalSeekBar) {
				// TODO Auto-generated method stub
				
			}

        });
    }
}

同样遇到此问题，重写了verticalSeekBar ,4.1没问题，5.0的就有问题了。
