Android开发ScrollView下上左右滑动事件冲突整理二（根据角度）

Android的ScrollView滑动获得角度实例：

package com.cm.android.pad.view.itemView;import android.content.Context;import android.util.AttributeSet;import android.view.GestureDetector;import android.view.GestureDetector.SimpleOnGestureListener;import android.view.MotionEvent;import android.view.View;import android.widget.ScrollView;public class TestScroll extends ScrollView {	private GestureDetector mGestureDetector;	private static double SCROLL_ANGLE = 90;	public TestScroll(Context context, AttributeSet attrs) {		super(context, attrs);		mGestureDetector = new GestureDetector(new YScrollDetecotr());		setFadingEdgeLength(0);	}	@Override	public boolean onInterceptTouchEvent(MotionEvent ev) {		return super.onInterceptTouchEvent(ev)				&& mGestureDetector.onTouchEvent(ev);	}	class YScrollDetecotr extends SimpleOnGestureListener {		@Override		public boolean onScroll(MotionEvent e1, MotionEvent e2,				float distanceX, float distanceY) {			// if(distanceY != 0 && distanceX != 0){			//			// }			// if(Math.abs(distanceY) >= Math.abs(distanceX)){			// System.out.println("distanceX = " + distanceX + " , distanceY = "			// + distanceY);			// return true;			// }			// return false;			double angle = Math.atan2(Math.abs(distanceY), Math.abs(distanceX));//			System.out.println("angle-->" + (180 * angle) / Math.PI);			if ((180 * angle) / Math.PI < 180) {				return false;			}			return false;		}	}}
