HorizontalScrollView與ListView滑動事件衝突，導致ListView下拉不靈敏。下面給出一種比較完美的實現方式，如果是縱向的ScrollView，對應改一下就好了~~上程式碼

package wosai.com.membermarketing.util.layout;

import android.content.Context;
import android.util.AttributeSet;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
import android.widget.HorizontalScrollView;

/**
 * 自定義HorizontalScrollView，解決滑動事件衝突
 *
 * Created by yuyh on 2015/10/30.

public class CustomHorizontalScrollView extends HorizontalScrollView {

    float lastX, lastY;

    private GestureDetector mGestureDetector;
    View.OnTouchListener mGestureListener;

    public CustomHorizontalScrollView(Context context) {
        super(context);
        mGestureDetector = new GestureDetector(context, new YScrollDetector());
        setFadingEdgeLength(0);
    }

    public CustomHorizontalScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
        mGestureDetector = new GestureDetector(context, new YScrollDetector());
        setFadingEdgeLength(0);
    }

    public CustomHorizontalScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mGestureDetector = new GestureDetector(context, new YScrollDetector());
        setFadingEdgeLength(0);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
    }

    /**
     * 如果豎向滑動距離<橫向距離，執行橫向滑動，否則豎向。如果是ScrollView，則'<'換成'>'
     */
    class YScrollDetector extends GestureDetector.SimpleOnGestureListener {
        @Override
        public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
            if (Math.abs(distanceY) < Math.abs(distanceX)) {
                return true;
            }
            return false;
        }
    }
}
