Android ScrollView touch 处理中的 Horizo​​ntalScrollView

我有一个围绕整个布局的ScrollView，因此整个屏幕都是可滚动的.这个ScrollView中的第一个元素是HorizontalScrollView挡路，它具有可以水平滚动的功能.我已经向Horizontalscroll视图添加了一个ontouch侦听器来处理touch 事件，并强制视图"捕捉"到action_up事件上最接近的图像.

所以我想要的效果就像是普通的Android主屏幕，你可以从一个滚动到另一个，当你抬起手指时，它就会弹到一个屏幕上.

这一切都很好，除了一个问题:我需要从左向右几乎完美地水平滑动一个动作直到注册为止.如果我至少垂直滑动(我认为很多人在手机上从一边到另一边滑动时都会这样做)，我会收到一个动作取消，而不是一个动作向上.我的理论是，这是因为horizontalscrollview在scrollview中，而scrollview正在劫持垂直touch 以允许垂直滚动.

如何在水平滚动视图中禁用滚动视图的touch 事件，但仍允许在滚动视图的其他位置进行正常的垂直滚动？

以下是我的代码示例:

   public class HomeFeatureLayout extends HorizontalScrollView {
    private ArrayList<ListItem> items = null;
    private GestureDetector gestureDetector;
    View.OnTouchListener gestureListener;
    private static final int SWIPE_MIN_DISTANCE = 5;
    private static final int SWIPE_THRESHOLD_VELOCITY = 300;
    private int activeFeature = 0;

    public HomeFeatureLayout(Context context, ArrayList<ListItem> items){
        super(context);
        setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
        setFadingEdgeLength(0);
        this.setHorizontalScrollBarEnabled(false);
        this.setVerticalScrollBarEnabled(false);
        LinearLayout internalWrapper = new LinearLayout(context);
        internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
        internalWrapper.setOrientation(LinearLayout.HORIZONTAL);
        addView(internalWrapper);
        this.items = items;
        for(int i = 0; i< items.size();i++){
            LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.homefeature,null);
            TextView header = (TextView) featureLayout.findViewById(R.id.featureheader);
            ImageView image = (ImageView) featureLayout.findViewById(R.id.featureimage);
            TextView title = (TextView) featureLayout.findViewById(R.id.featuretitle);
            title.setTag(items.get(i).GetLinkURL());
            TextView date = (TextView) featureLayout.findViewById(R.id.featuredate);
            header.setText("FEATURED");
            Image cachedImage = new Image(this.getContext(), items.get(i).GetImageURL());
            image.setImageDrawable(cachedImage.getImage());
            title.setText(items.get(i).GetTitle());
            date.setText(items.get(i).GetDate());
            internalWrapper.addView(featureLayout);
        }
        gestureDetector = new GestureDetector(new MyGestureDetector());
        setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (gestureDetector.onTouchEvent(event)) {
                    return true;
                }
                else if(event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL ){
                    int scrollX = getScrollX();
                    int featureWidth = getMeasuredWidth();
                    activeFeature = ((scrollX + (featureWidth/2))/featureWidth);
                    int scrollTo = activeFeature*featureWidth;
                    smoothScrollTo(scrollTo, 0);
                    return true;
                }
                else{
                    return false;
                }
            }
        });
    }

    class MyGestureDetector extends SimpleOnGestureListener {
        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            try {
                //right to left 
                if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    activeFeature = (activeFeature < (items.size() - 1))? activeFeature + 1:items.size() -1;
                    smoothScrollTo(activeFeature*getMeasuredWidth(), 0);
                    return true;
                }  
                //left to right
                else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    activeFeature = (activeFeature > 0)? activeFeature - 1:0;
                    smoothScrollTo(activeFeature*getMeasuredWidth(), 0);
                    return true;
                }
            } catch (Exception e) {
                // nothing
            }
            return false;
        }
    }
}
