Answer 1

你重写ScrollView类
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    final float x = ev.getX();
    final float y = ev.getY();    final int action = ev.getAction();
    switch (action) {
        case MotionEvent.ACTION_DOWN:
            mDownPosX = x;
            mDownPosY = y;            break;
        case MotionEvent.ACTION_MOVE:
            final float deltaY = Math.abs(y - mDownPosY);
            // 这里是够拦截的判断依据是左右滑动，读者可根据自己的逻辑进行是否拦截
            if (deltaY > 5) {
                return false;
            }
    }    return super.onInterceptTouchEvent(ev);
}
