NestedScrollView中的NestedScrollview未滚动

Question

我知道这个问题经常出现，但我尝试了几乎所有的解决方案，即使是神奇的解决方案显然对我也不起作用！：(家长是NestedScrollview，孩子中有另一个NestedScrollview)

    parent.setOnTouchListener(new View.OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            Log.v(TAG,"PARENT TOUCH");
            child.getParent().requestDisallowInterceptTouchEvent(false);
            return false;
        }
    });

    child.setOnTouchListener(new View.OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event)
        {
            Log.v(TAG,"CHILD TOUCH");
            // Disallow the touch request for parent scroll on touch of child view
            v.getParent().requestDisallowInterceptTouchEvent(true);
            return false;
        }
    });

在Logcat上，我得到了“父母接触”和“孩子接触”，但Chidl不滚动！奇怪的是，这个解决方案和其他解决方案适用于其他人，而不是我

这是我的xml结构：(PS:我很乐意尝试您的解决方案)(编辑后

Answer 1

通过创建以下内容解决了此问题：

public class NoInterceptScrollView extends ScrollView {

    public NoInterceptScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return false;
    }

}

并将其用作父类..and将两个嵌套的scrollview更改为scrollview+我删除了禁用父触摸的代码……
