My setup is simple enough:
I get some code from net.
Change scrollView
to Special scrollview
:
package com.image.indicator.control;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.ScrollView;
/**
* @File: ScrollViewExtend.java
* @Package com.image.indicator.control
* @Author Hanyonglu
* @Date 2012-6-18
* @Version V1.0
*/
public class ScrollViewExtend extends ScrollView {
private float xDistance, yDistance, xLast, yLast;
public ScrollViewExtend(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
xDistance = yDistance = 0f;
xLast = ev.getX();
yLast = ev.getY();
break;
case MotionEvent.ACTION_MOVE:
final float curX = ev.getX();
final float curY = ev.getY();
xDistance += Math.abs(curX - xLast);
yDistance += Math.abs(curY - yLast);
xLast = curX;
yLast = curY;
if(xDistance > yDistance){
return false;
}
}
return super.onInterceptTouchEvent(ev);
}
}
Or change RecyclerView
to ViewPager
:
public class ChildViewPager extends ViewPager{
/** 触摸时按下的点 **/
PointF downP = new PointF();
/** 触摸时当前的点 **/
PointF curP = new PointF();
OnSingleTouchListener onSingleTouchListener;
public ChildViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public ChildViewPager(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
@Override
public boolean onInterceptTouchEvent(MotionEvent arg0) {
// TODO Auto-generated method stub
//当拦截触摸事件到达此位置的时候,返回true,
//说明将onTouch拦截在此控件,进而执行此控件的onTouchEvent
return true;
}
@Override
public boolean onTouchEvent(MotionEvent arg0) {
// TODO Auto-generated method stub
//每次进行onTouch事件都记录当前的按下的坐标
curP.x = arg0.getX();
curP.y = arg0.getY();
if(arg0.getAction() == MotionEvent.ACTION_DOWN){
//记录按下时候的坐标
//切记不可用 downP = curP ,这样在改变curP的时候,downP也会改变
downP.x = arg0.getX();
downP.y = arg0.getY();
//此句代码是为了通知他的父ViewPager现在进行的是本控件的操作,不要对我的操作进行干扰
getParent().requestDisallowInterceptTouchEvent(true);
}
if(arg0.getAction() == MotionEvent.ACTION_MOVE){
//此句代码是为了通知他的父ViewPager现在进行的是本控件的操作,不要对我的操作进行干扰
getParent().requestDisallowInterceptTouchEvent(true);
}
if(arg0.getAction() == MotionEvent.ACTION_UP){
//在up时判断是否按下和松手的坐标为一个点
//如果是一个点,将执行点击事件,这是我自己写的点击事件,而不是onclick
if(downP.x==curP.x && downP.y==curP.y){
onSingleTouch();
return true;
}
}
return super.onTouchEvent(arg0);
}
/**
* 单击
*/
public void onSingleTouch() {
if (onSingleTouchListener!= null) {
onSingleTouchListener.onSingleTouch();
}
}
/**
* 创建点击事件接口
* @author wanpg
*
*/
public interface OnSingleTouchListener {
public void onSingleTouch();
}
public void setOnSingleTouchListener(OnSingleTouchListener onSingleTouchListener) {
this.onSingleTouchListener = onSingleTouchListener;
}
}
