使用自定義垂直SeekBar，拇指高亮不會隨着酒吧旋轉

我正在使用自定義垂直Seekbar，除拇指突出顯示外，一切都很好。使用自定義垂直SeekBar，拇指高亮不會隨着酒吧旋轉

正如我滾動左側搜索條上下，拇指亮點繼續滾動左到右在屏幕的頂部，如果搜索條仍然是水平的。我的自定義垂直搜索條如下：

public class VerticalSeekBar extends SeekBar { 

protected OnSeekBarChangeListener changeListener; 

public VerticalSeekBar(Context context) { 
    super(context); 
} 

public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
} 

public VerticalSeekBar(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

protected void onSizeChanged(int w, int h, int oldw, int oldh) { 
    super.onSizeChanged(h, w, oldh, oldw); 
} 

@Override 
protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
    super.onMeasure(heightMeasureSpec, widthMeasureSpec); 
    setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth()); 
} 

@Override 
public synchronized void setProgress(int progress) { 
    super.setProgress(progress); 
    onSizeChanged(getWidth(), getHeight(), 0, 0); 
} 

@Override public void setOnSeekBarChangeListener(OnSeekBarChangeListener mListener) 
{ 
    this.changeListener = mListener; 
} 

protected void onDraw(Canvas c) { 
    c.rotate(-90); 
    c.translate(-getHeight(),0); 

    super.onDraw(c); 
} 

@Override 
public boolean onTouchEvent(MotionEvent event) { 
    if (!isEnabled()) { 
     return false; 
    } 

    switch (event.getAction()) { 
     case MotionEvent.ACTION_DOWN: 
      setProgress(getMax() - (int) (getMax() * event.getY()/getHeight())); 
      if (changeListener != null) 
       changeListener.onStartTrackingTouch(this); 
      setSelected(true); 
      setPressed(true); 
      break; 
     case MotionEvent.ACTION_UP: 
      if (changeListener != null) 
       changeListener.onStopTrackingTouch(this); 
      setSelected(false); 
      setPressed(false); 
      break; 
     case MotionEvent.ACTION_MOVE: 
      int i=getMax() - (int) (getMax() * event.getY()/getHeight()); 
      setProgress(i); 
      onSizeChanged(getWidth(), getHeight(), 0, 0); 
      if (changeListener != null) 
       changeListener.onProgressChanged(this, i, true); 
      setPressed(true); 
      setSelected(true); 
      break; 
     case MotionEvent.ACTION_CANCEL: 
      break; 
    } 
    return true; 
} 

}
