MapView-禁止拖动，但允许缩放 [英] MapView - Disable dragging around, but allow zooming

问题描述

我有一个ViewPager，里面有3个片段，在最右边，我想显示一个MapView-到目前为止运行良好.但是我想禁用它的拖动功能，但仍然允许用户使用固定的中心放大/缩小.如果允许用户拖动地图，则它会与Viewpager滚动功能混为一谈. 试图禁用可点击+聚焦，但是-当然-不再缩放.

I have a ViewPager with 3 fragments inside, on the outer right I want to display a MapView - working fine so far. But I'd like to disable dragging it around, but still let the user zoom in / out - with a fixed center. If the user would be allowed to drag the map around, it messes with the viewpager scrolling abilities. Tried to disable clickable + focusable but - of course - no zooming anymore..

在stackoverflow上查看了其他问题，但到目前为止，没有一个提供有效的解决方案.

Looked at other questions here at stackoverflow but none provided a working solution so far..

谢谢！

推荐答案

忽略我到目前为止所说的一切(这就是我编辑答案的原因)，而是在MapActivity类中使用以下代码(它可以正常工作，只需尝试一下！):

Ignore everything I've said so far (which is why I've edited my answer), instead use the following code in your MapActivity class(it works perfectly, just tried it!):

final GeoPoint point = new GeoPoint(latitudeE6, longitudeE6);
final MapController mapController = mapView.getController();

mapController.animateTo(point);
mapController.setZoom(6);

mapView.setOnTouchListener(new View.OnTouchListener() {

@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
  if(arg1.getAction() ==  MotionEvent.ACTION_UP)
  {
    mapController.setCenter(point);
    return true;
  }
  if(arg1.getPointerCount() > 1)
  {
   mapController.setCenter(point);
   return false;
  }
  else
  {
   return true;
  }
 } 
 });
