ScrollView嵌套Scrollview滑动冲突

来源：互联网发布：淘宝哪家手办店好编辑：程序博客网时间：2024/05/03 22:21

主要解决的问题：实现父控件和子控件都可以滑动，并且当子控件滑动到最低端，继续滑动的时候，获得父控件焦点，同理，向上滑动
步骤：
第一步：继承OnTouchListener，第二步：帖代码
/**
  * ScrollView中嵌套SrcollView 滑动冲突
  */
float start=0;
float start1=0;
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
  switch (arg0.getId()) {
  case R.id.scrParent://父控件布局
scrChild.getParent().requestDisallowInterceptTouchEvent(false);
scrChildren.getParent().requestDisallowInterceptTouchEvent(false);
break;
  case R.id.scrChild://子控件布局
if ((arg1.getY() - start) > 0) {
if (arg0.getScrollY() == 0) {
   arg0.getParent().requestDisallowInterceptTouchEvent(false);
} else {
   arg0.getParent().requestDisallowInterceptTouchEvent(true);
}
} else {
if (arg0.getHeight() + arg0.getScrollY() >= scrChild
   .getChildAt(0).getMeasuredHeight()) {
   arg0.getParent().requestDisallowInterceptTouchEvent(false);
} else {
   arg0.getParent().requestDisallowInterceptTouchEvent(true);
}
}
start = arg1.getY();
break;
  case R.id.scrChildren:
if ((arg1.getY() - start1) > 0) {
if (arg0.getScrollY() == 0) {
   arg0.getParent().requestDisallowInterceptTouchEvent(false);
} else {
   arg0.getParent().requestDisallowInterceptTouchEvent(true);
}
} else {
if (arg0.getHeight() + arg0.getScrollY() >= scrChild
   .getChildAt(0).getMeasuredHeight()) {
   arg0.getParent().requestDisallowInterceptTouchEvent(false);
} else {
   arg0.getParent().requestDisallowInterceptTouchEvent(true);
}
}
start1 = arg1.getY();
break;
  }
  return false;
}
