ScrollView嵌套Viewpager和ListView的整合
1、ScrollView嵌套Viewpager解决滑动冲突:
(1)重新ScrollView(法一)
/** * 能够兼容ViewPager的ScrollView * @Description: 解决了ViewPager在ScrollView中的滑动反弹问题 */ public class ScrollViewExtend extends ScrollView { // 滑动距离及坐标 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); } } |
(2)重新ScrollView(法二)
public class MyScrollView extends ScrollView { private boolean canScroll;
private GestureDetector mGestureDetector; View.OnTouchListener mGestureListener;
public MyScrollView(Context context, AttributeSet attrs) { super(context, attrs); mGestureDetector = new GestureDetector(new YScrollDetector()); canScroll = true; } @Override public boolean onInterceptTouchEvent(MotionEvent ev) { if(ev.getAction() == MotionEvent.ACTION_UP) canScroll = true; return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev); }
class YScrollDetector extends SimpleOnGestureListener { @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { if(canScroll) if (Math.abs(distanceY) >= Math.abs(distanceX)) canScroll = true; else canScroll = false; return canScroll; } } } |
个人是用第一个方法解决的,根据不同的情况可以自己处理!
