如何使 Google 地图在滚动视图中正确滚动?
How to make Google Maps scroll properly inside Scroll View?
我有一个片段,它包含一个地图(视图),它位于我的布局的滚动视图中。
问题是地图不能正确向上或向下滚动(难以滚动)。滚动视图似乎干扰了地图的垂直滚动。它水平滚动(平滑),而不是垂直滚动。
我该如何解决这个问题?

对于google map v2,按照本教程的解决方案
您可以添加适合 mapFragment 的透明 ImageView:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imagetrans"
android:layout_alignTop="@+id/mapfragment"
android:layout_alignBottom="@+id/mapfragment"
android:layout_alignEnd="@+id/mapfragment"
android:layout_alignRight="@+id/mapfragment"
android:layout_alignLeft="@+id/mapfragment"
android:layout_alignStart="@+id/mapfragment"
android:src="@color/transparent"/>
然后,当用户触摸它时,禁止滚动视图:
final ScrollView scroll = (ScrollView) findViewById(R.id.scroll);
ImageView transparent = (ImageView)findViewById(R.id.imagetrans);
transparent.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
scroll.requestDisallowInterceptTouchEvent(true);
// Disable touch on transparent view
return false;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
scroll.requestDisallowInterceptTouchEvent(false);
return true;
case MotionEvent.ACTION_MOVE:
scroll.requestDisallowInterceptTouchEvent(true);
return false;
default:
return true;
}
}
});
这样,只有当用户触摸ImageView时,地图才会响应触摸事件。其余时间,ScrollView 会响应。
