防止垂直搜索栏在点击时移动

Question

我在水平列表视图中使用垂直搜索栏。现在，即使在进度绘制中手指触摸，搜索栏也会移动。但我只想在拇指移动的时候移动它。当触摸progressdrawable时，搜索栏的值不应该改变。我怎样才能预防呢?

public class VerticalSeekBar extends SeekBar {
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());
}
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:
        case MotionEvent.ACTION_UP:
        case MotionEvent.ACTION_MOVE:
            int i=0;
            i=getMax() - (int) (getMax() * event.getY() / getHeight());
            setProgress(i);
            onSizeChanged(getWidth(), getHeight(), 0, 0);
            break;
        case MotionEvent.ACTION_CANCEL:
            break;
    }
    return true;
}
Drawable mThumb;
@Override
public void setThumb(Drawable thumb) {
    super.setThumb(thumb);
    mThumb = thumb;
}
public Drawable getSeekBarThumb() {
    return mThumb;
}
public void updateThumb(){
    onSizeChanged(getWidth(), getHeight(), 0, 0);

}}

我的解决方法如下:如果触摸到拇指图像的外部，它不会改变查找条的值。

holder.vertical_seekBar.setOnTouchListener(new OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if(event.getAction() == MotionEvent.ACTION_MOVE ||
                            event.getAction() == MotionEvent.ACTION_UP ||
                            event.getAction() == MotionEvent.ACTION_DOWN){
                        Rect seekBarThumbRect = holder.vertical_seekBar.getSeekBarThumb().getBounds();
                        int seekBarHeight = holder.vertical_seekBar.getHeight();
                        if(seekBarThumbRect.left - (seekBarThumbRect.right - seekBarThumbRect.left) / 2 < (Math.abs(seekBarHeight - event.getY())) &&
                                seekBarThumbRect.right + (seekBarThumbRect.right - seekBarThumbRect.left) / 2 > (Math.abs(seekBarHeight - event.getY())) &&
                                seekBarThumbRect.top < event.getX() &&
                                seekBarThumbRect.bottom > event.getX())
                                        return false;
                    }
                    return true;
                }
            });
