ScrollView 内的 MapView? [英] MapView inside a ScrollView?

问题描述

我想在 ScrollView 中有一个 MapView，但是当我尝试滚动地图时，ScrollView 优先！有没有办法在地图内滚动时给 MapView 优先级，否则给 ScrollView?

I would like to have a MapView inside a ScrollView, however when I try to scroll the map, the ScrollView takes priority! Is there a way to give the MapView priority when scrolling inside the map, and the ScrollView otherwise?

谢谢！

推荐答案

我遇到了同样的问题 10 天了，但几分钟前我得到了解决方案！！这是解决方案.我制作了一个自定义 MapView 并像这样覆盖 onTouchEvent().

I have had a same problem for 10 days, but I got a solution a few minutes ago!! Here is the solution. I made a custom MapView and override onTouchEvent() like this.

@Override
public boolean onTouchEvent(MotionEvent ev) {
    int action = ev.getAction();
    switch (action) {
    case MotionEvent.ACTION_DOWN:
        // Disallow ScrollView to intercept touch events.
        this.getParent().requestDisallowInterceptTouchEvent(true);
        break;

    case MotionEvent.ACTION_UP:
        // Allow ScrollView to intercept touch events.
        this.getParent().requestDisallowInterceptTouchEvent(false);
        break;
    }

    // Handle MapView's touch events.
    super.onTouchEvent(ev);
    return true;
}
