android - scrollView Inside Horizo​​ntal Scrollview 无法正常工作

Question

希望我们玩的开心/p>

当我尝试滚动布局时，只允许我向一个方向滚动，而不是同时向两个方向滚动。我认为这是 android 真正的问题。

请提供任何解决方案。问候

有比创建自定义 View 更简单的解决方案:

布局:

<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/scrollHorizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ScrollView 
        android:id="@+id/scrollVertical"
        android:layout_width="wrap_content"
        android:layout_height="match_parent" >

        <WateverViewYouWant/>

    </ScrollView>
</HorizontalScrollView>

代码(onCreate/onCreateView):

    final HorizontalScrollView hScroll = (HorizontalScrollView) value.findViewById(R.id.scrollHorizontal);
    final ScrollView vScroll = (ScrollView) value.findViewById(R.id.scrollVertical);
    vScroll.setOnTouchListener(new View.OnTouchListener() { //inner scroll listener         
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return false;
        }
    });
    hScroll.setOnTouchListener(new View.OnTouchListener() { //outer scroll listener         
        private float mx, my, curX, curY;
        private boolean started = false;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            curX = event.getX();
            curY = event.getY();
            int dx = (int) (mx - curX);
            int dy = (int) (my - curY);
            switch (event.getAction()) {
                case MotionEvent.ACTION_MOVE:
                    if (started) {
                        vScroll.scrollBy(0, dy);
                        hScroll.scrollBy(dx, 0);
                    } else {
                        started = true;
                    }
                    mx = curX;
                    my = curY;
                    break;
                case MotionEvent.ACTION_UP: 
                    vScroll.scrollBy(0, dy);
                    hScroll.scrollBy(dx, 0);
                    started = false;
                    break;
            }
            return true;
        }
    });

您可以更改 ScrollView 的顺序。只需更改它们在布局和代码中的顺序。很明显，您放置了想要双向滚动的布局/ View ，而不是 WateverViewYouWant。
